The Amount of Exercise That Can Boost The Aging Brain

The right amount of exercise to help boost the older brain.

The right amount of exercise to help boost the older brain.

A relatively small increase in exercise is enough to boost brain function in older adults, a new study finds.

The amount of exercise that’s beneficial is equivalent to a brisk 25-minute walk several times a week.

Healthy over-65s who exercised more had better attention and ability to focus, the research found.

Professor Jeffrey Burns, co-director of the Kansas University Alzheimer’s Disease Center, said:

“Basically, the more exercise you did, the more benefit to the brain you saw.

Any aerobic exercise was good, and more is better.”

For the study, 101 healthy people over 65 were split into four groups, three of which did some extra exercise.

The three groups did 75, 150 and 225 minutes of exercise per week.

They were compared with a group that were relatively sedentary.

All the groups saw some benefit, but the more exercise people did, the better they performed in cognitive tests.

The extra mental boost from exercise above 75 minutes, though, was only small.

It wasn’t so much the duration of the exercise, the researchers found, it was more about the intensity.

Dr Eric Vidoni, the study’s first author, said:

“For improved brain function, the results suggest that it’s not enough just to exercise more.

You have to do it in a way that bumps up your overall fitness level.”

One of the participants in the study, Marjorie Troeh, 80, explained she used the study as a way of motivating herself:

“I love exercising my mind, but I hate exercising my body.

I knew about the evidence that said exercise was good for endurance and agility, but I really didn’t make any connection with that and brain health.

I’m surrounded by people who face memory problems.

I’m really anxious to do anything I can to further knowledge in this area.”

The research was published in the journal PLOS ONE (Vidoni et al., 2015).

How Parents Misjudge Their Children’s Happiness

Parents are often mistaken when guessing how happy their children are.

Parents are often mistaken when guessing how happy their children are.

Fifteen and sixteen-year-olds are happier than their parents think, a new study finds.

However, ten and eleven-year-olds are not as happy as their parents think.

The children themselves reported being equally happy in both age-groups.

The difference is all down to how parents judge their children.

Parents of adolescents tend to be less happy than parents of younger children.

This leads them to assume their adolescent children are less happy.

The culprit is the ‘egocentric bias’: a tendency to rely too much on your own feelings to assess those of other people.

The conclusions come from a study of 357 children and adolescents in Spain, along with their parents.

The study also found that, on average, across both age-groups, children weren’t as happy as their parents assumed.

Dr Belén López-Pérez, the study’s first author, said:

“Being unable to read children’s happiness appropriately may increase misunderstanding between parents and children/adolescents, which has been shown to have negative consequences for parent-child relationships.

Furthermore, parents might not be able to provide the appropriate emotional support or attend to their children’s needs accurately.”

The research was published in the Journal of Experimental Child Psychology (López-Pérez & Wilson, 2015).

Alcohol’s Unexpected Effect on Memory and Learning

Surprisingly, alcohol is not bad for all types of memory.

Surprisingly, alcohol is not bad for all types of memory.

Alcohol can actually help some areas of the brain learn and remember.

While it’s true that alcohol is generally bad for conscious memory, it can boost unconscious memory.

This may help explain why alcohol — and other drugs — can be so habit-forming.

Dr Hitoshi Morikawa, an addiction researcher, said:

“Usually, when we talk about learning and memory, we’re talking about conscious memory.

Alcohol diminishes our ability to hold on to pieces of information like your colleague’s name, or the definition of a word, or where you parked your car this morning.

But our subconscious is learning and remembering too, and alcohol may actually increase our capacity to learn, or ‘conditionability’.”

Dr Morikawa and colleagues reached this conclusion by exposing mice to alcohol and examining synaptic plasticity in key areas of the brain.

They found that with repeated exposure, the plasticity increased — indicating learning.

The unconscious, though, is learning more than just that drinking feels good.

It is learning a whole constellation of behavioral, environmental and social triggers.

For example, it is learning that particular music, people and places are linked to a surge of pleasure.

Neurobiologically, this means the brain is releasing dopamine, says Dr Morikawa:

“People commonly think of dopamine as a happy transmitter, or a pleasure transmitter, but more accurately it’s a learning transmitter.

It strengthens those synapses that are active when dopamine is released.”

As the drinking is repeated again in the same context, the brain becomes more sensitive to this situation.

In other words: it learns to enjoy the drinking more and more.

Treating alcoholism, and other addictions, is partly about picking apart this web of situations and emotions.

Dr Morikawa said:

“We’re talking about de-wiring things.

It’s kind of scary because it has the potential to be a mind controlling substance.

Our goal, though, is to reverse the mind controlling aspects of addictive drugs.”

The study was published in The Journal of Neuroscience (Bernier et al., 2011).

The Mood Most People Are In Most of The Time, Everywhere

How people feel, on average, most of the time, wherever they live in the world.

How people feel, on average, most of the time, wherever they live in the world.

People are, on average, in a mildly good mood most of the time all around the world, a new study finds.

Researchers have reviewed evidence drawn from many different nations — rich and poor, stable and unstable.

As long as people have not just experienced a strong emotional event, even those in poor circumstances are likely to be in a mild positive mood.

The study’s authors write:

“According to our hypothesis, humans have been evolutionarily selected to have a positive mood offset, and the higher-than-neutral level of happiness is genetically transmitted from parents to children, while chronic depression and lack of positive affect have been selected out.

People are happy most of the time because they are descended from ancestors who were happier and engaged in fitness-maximizing behavior more frequently than their neighbors who were less happy.

Current good and bad events can move people temporarily away from their baseline levels, but people will return toward that level over time.

Long-term bad and good circumstances can move the baseline up or down, but only within a range.”

The reason being mildly happy is beneficial to our future?

Being happy makes you more likely to plan for the future, be creative, be social and, crucially, to mate.

The study was published in the journal Personality and Social Psychology Review (Diener et al., 2015).

7 Wise Happiness Quotes — But Which Ones Are Really True?

Answers to: whether happiness comes with age, whether it is better to be unemployed than in a job you hate, and more…

Answers to: whether happiness comes with age, whether it is better to be unemployed than in a job you hate, and more…

Americans are generally a pretty happy group.

People in the US are six times more likely to say they are happy than unhappy, according to a new poll by CivicScience.

Here are a few wise quotes about happiness from some big names.

Do their bon mots ring true?

“There is an unspeakable dawn in happy old age.” – Victor Hugo

True.

People really do get happier as they get older.

In the survey, people over 65 were 14 times more likely to be happy than unhappy.

From the age of around 30, people report feeling progressively happier, on average.

“Choose a job you love, and you will never have to work a day in your life.”  Confucius

True.

The survey even found evidence that it may be better to be out of work than to be in a job that you hate.

Although, obviously, neither situations is ideal.

“Happiness quite unshared can scarcely be called happiness; it has no taste.” ― Charlotte Brontë

True.

Married people consistently report being 20% happier than unmarried people.

There’s some evidence that parents are happier than non-parents.

“Money may not buy happiness, but I’d rather cry in a Jaguar than on a bus.” — Françoise Sagan

True up to a point.

And that point in the US is around $100,000 in earnings per year.

After that, more money seems to do little for happiness — indeed more may make you less happy.

If you’ve got enough money to be able to go to an upscale restaurant every now and then or to buy yourself the odd trinket, then perhaps you’ve got enough?

“Happy girls are the prettiest.”  Audrey Hepburn

Sort of true, but not as true as you might imagine.

People who are more attractive do repeatedly report being slightly happier than their less bodily-advantaged peers.

But it may partly depend where those girls (or boys) live.

In the city where it’s more about looks, being attractive may make you happier.

In the countryside, though, the link is less clear-cut.

(Alternatively, if Audrey meant that looking happy increases your attractivity, then: DEFINITELY TRUE!)

To keep the body in good health is a duty… otherwise we shall not be able to keep our mind strong and clear.” – Buddha

True.

You can’t argue with Buddha, can you?

“I felt my lungs inflate with the onrush of scenery—air, mountains, trees, people. I thought, ‘This is what it is to be happy.’”  Sylvia Plath

Plath not exactly known for her quotes about happiness.

Nevertheless: true.

Get out into nature, travel and explore.

All were linked to higher levels of happiness in the poll.

About the poll

The poll included data from 262,000 Americans.

They were asked about their lifestyles, demographics and many other characteristics.

Emotional Insights: 10 Awesome New Psych Studies That Will Uplift and Intrigue You

The wonderful power of awe, the source of life’s most emotional moments. Plus: you really can smell happiness…

The wonderful power of awe, the source of life’s most emotional moments. Plus: you really can smell happiness…

1. Awe expands time and increases well-being

Awe makes people more patient, less materialistic and more open to helping out others.

This happens, authors of a recent study think, because awe slows down our subjective experience of time.

The researchers described their conclusions:

“People increasingly report feeling time starved, and that feeling exacts a toll on health and well-being.

Drawing on research showing that being in the present moment elongates time perception, we predicted and found that experiencing awe, relative to other states, caused people to perceive that they had more time available and lessened impatience.

Furthermore, by expanding time perception, awe, compared with other states, led participants to more strongly desire to spend time helping other people and to partake in experiential goods over material ones.”

2. Awe protects mind and body

The wonderful effects of awe do not end with expanding time and increasing well-being.

Positive emotions, especially the feeling of awe, have been linked to lower levels of inflammatory cytokines by a recent study.

The research suggests that the positive feeling from enjoying the beauty of nature or getting lost in a painting or symphony can actually help protect the body against heart disease, arthritis, depression, and even Alzheimer’s disease.

3. Why happiness makes people cry

When you think about it, these are pretty weird:

  • Spouses cry when reunited with a soldier returning from war.
  • Lottery winners disintegrate into floods of tears.
  • Soccer players scream when they score the winning goal.
  • Teenage girls scream and cry at a Justin Bieber concert.

Shedding tears might seem a strange response to happiness, but a recent study suggests that it helps people cope with overwhelming emotions.

Crying tears of joy may be the mind’s way of restoring emotional equilibrium, according to the study.

4. All human communication is positive (that’s on average!)

Apparently, human communication is pretty happy, overall.

Across multiple languages and in many modes — movie subtitles, music lyrics, Russian literature — human communication skews towards the positive, a recent study found.

Professor Peter Dodds, a mathematician and the study’s lead author, said:

“We looked at ten languages, and in every source we looked at, people use more positive words than negative ones.”

While some sources were more positive than others, with Chinese books being the least positive and Spanish-language websites being the most positive, all the samples averaged above the neutral point.

This was even the case for English language song lyrics, which were ranked 22 out of 24 categories for happiness, with only Chinese novels and Korean subtitles being less happy.

5. Men and women process emotions in different ways

Women rate emotional images as more stimulating and are more likely to remember them than men, a recent study found.

While strong emotions tend to boost memory for both men and women, this neuroimaging study may help explain why women often outperform men on memory tests.

Women found the emotional pictures — and especially the negative pictures — more stimulating than the men.

Dr Klara Spalek, the study’s first author, said:

“This result would support the common belief that women are more emotionally expressive than men.”

6. A common painkiller also kills pleasure

Acetaminophen — also known as Tylenol (or paracetamol outside the US) — kills positive emotions, a study has found.

Studies have already shown that the painkiller blunts both physical and psychological pain.

But this is the first time anyone has thought to test the popular painkiller’s effect on both negative and positive emotions.

Geoffrey Durso, the study’s lead author, said:

“This means that using Tylenol or similar products might have broader consequences than previously thought.

Rather than just being a pain reliever, acetaminophen can be seen as an all-purpose emotion reliever.”

7. Genes make some people more emotionally reactive

Carriers of a certain genetic variation experience positive and negative emotions more strongly, a recent study suggests.

The genetic variant is carried by around 50% of Caucasians — although the percentage varies between ethnicities.

The feelings are accompanied by greater activation in regions of the brain linked to emotional processing.

The study may help to explain why some people are particularly susceptible to post-traumatic stress disorder (PTSD).

8. Life’s highest highs and lowest lows come from…

When you look back over your life, which moments have given you the most pain — and which the most pleasure?

Some might guess it’s individual achievements, like getting a promotion, or individual failures, like failing an exam.

In fact, research suggests that it’s the highs and lows of social relationships that provide the highest highs and lowest lows.

Dr. Shira Gabriel, whose study this finding is based on, said:

“Most of us spend much of our time and effort focused on individual achievements such as work, hobbies and schooling.

However this research suggests that the events that end up being most important in our lives, the events that bring us the most happiness and also carry the potential for the most pain, are social events — moments of connecting to others and feeling their connections to us.”

9. It’s emotions that make diets hard to follow

As every dieter knows, planning a diet and actually following through are two completely different things.

The reason is that most people think their conscious thoughts and intentions will change their behaviour, when in fact they don’t.

What really drives a lot of actual, real-world dieting behaviour is the emotions.

Dr Marc Kiviniemi, a public health researcher at the University at Buffalo, explained:

“The crux of the disconnect is the divide between thoughts and feelings.

Planning is important, but feelings matter, and focusing on feelings and understanding their role can be a great benefit.

If you’re sitting back conceiving a plan you may think rationally about the benefits of eating healthier foods, but when you’re in the moment, making a decision, engaging in a behavior, it’s the feelings associated with that behavior that may lead you to make different decisions from those you planned to make.”

10. You really can smell happiness

People communicate their happiness to others through their perspiration.

There are chemical compounds in sweat, it turns out, that can be detected by others.

Previous studies have shown that we can smell fear and disgust in sweat — but happiness has been more of a gray area.

Professor Gün Semin, a psychologist at Utrecht University in the Netherlands, who led the study, said:

“Our study shows that being exposed to sweat produced under happiness induces a simulacrum of happiness in receivers, and induces a contagion of the emotional state.”

Study Tests If More Relationship Sex Really Boosts Happiness

Many self-help books claim that more sex in a relationship makes couples happier, but is it really true?

Many self-help books claim that more sex in a relationship makes couples happier, but is it really true?

Contrary to the claims of many self-help books, couples that have more sex are NOT happier, a new experiment finds.

When couples had more sex, researchers found, they reported wanting and enjoying it less — indeed their happiness was slightly reduced.

The conclusions come from a study of 64 heterosexual, married couples between the ages of 35 and 65.

The study asked some couples to double the amount of sex they had, while the rest were given no instruction.

The results showed that couples that had more sex were slightly less happy.

They also enjoyed the sex less and wanted it less.

Dr Tamar Krishnamurti, one of the study’s authors, said:

“The desire to have sex decreases much more quickly than the enjoyment of sex once it’s been initiated.

Instead of focusing on increasing sexual frequency to the levels they experienced at the beginning of a relationship, couples may want to work on creating an environment that sparks their desire and makes the sex that they do have even more fun.”

The researchers were open to alternative interpretations of their study, as good scientists should be.

Professor George Loewenstein, who led the study, said:

“Perhaps couples changed the story they told themselves about why they were having sex, from an activity voluntarily engaged in to one that was part of a research study.

If we ran the study again, and could afford to do it, we would try to encourage subjects into initiating more sex in ways that put them in a sexy frame of mind, perhaps with baby-sitting, hotel rooms or Egyptian sheets, rather than directing them to do so.”

Despite the study’s results, Professor Loewenstein thinks many couples can benefit from having more sex — as long as sex is initiated in the right way.

Nevertheless, the results fly in the face of a common finding that those who have more sex are happier.

However, the results of other studies may be caused by people who are happier tending to have more sex, rather than that more sex causes more happiness.

The study was published in the Journal of Economic Behavior & Organization (Loewenstein et al., 2015).

Top 3 Needs For Happy Life — Fascinating Changes Since 1938

How beliefs about what makes us happy have changed in the last 80 years.

How beliefs about what makes us happy have changed in the last 80 years.

Eighty years ago the top three things people thought were most important for happiness were security, knowledge and religion.

By 2014 only security was still in the top three, and the other two spots had changed to good humour and leisure.

Meanwhile religion had dropped to tenth, and last place.

The results come from two surveys carried out almost 80 years apart.

For both surveys people in Bolton, England replied to an advert asking them to answer the question “What is happiness?”

Here are some of the responses form both 1938 and 2014:

“Enough money to meet everyday needs and a little for pleasure.” (1938)

“Knowing that my rent is paid on time and I can afford to eat healthily.” (2014)

“I would like a little home, not many possessions … congenial and satisfying companionship, the availability of good music and books.” (1938)

“Engaging in my hobbies, spending time that is free of worry … Simple things like enjoying a nice meal or receiving care and affection.” (2014)

“When I come home from the pit and see my kiddies and wife, I am happy.” (1938)

“Simple things like going out for a walk…….you don’t need tons of material things to be happy, you just have to be happy in the place you live and with the people around you.” (2014)

Despite the changes in the top three, Sandie McHugh, one of the study’s authors, pointed out that there were a lot of similarities:

“The overall impression from the correspondence in 1938 is that happiness factors were rooted in everyday lives at home and within the community.

In 2014 many comments value family and friends, with good humour and leisure time also ranked highly.”

The results were presented at the Annual Conference of the British Psychological Society in Liverpool.

Introverts Prefer Mountains: How Your Personality Affects Where You Should Live

Whether it’s better to live in the mountains, on the plains, by the ocean — and the city that’s best for you.

Whether it’s better to live in the mountains, on the plains, by the ocean — and the city that’s best for you.

‘Introverts prefer mountains’ is one of the conclusions of a series of recent studies on the link between personality and place.

People view mountainous areas as being more peaceful and calm.

Extroverts, meanwhile, tend to prefer flat, open areas.

These are viewed as more exciting, sociable and stimulating.

The study also found that introverts are, indeed, more likely to live in mountainous areas, while extraverts tend to live on the flat.

Dr Shige Oishi, who led the study, said:

“Some cities and towns have geography that is more accommodating for some people than for others…if you know you’re introverted, then you may be rejuvenated by being in a secluded place, while an extrovert may be rejuvenated more in an open space.”

People’s preferences also changed depending on how they were feeling.

When they wanted to socialise, people thought of the ocean 75% of the time.

Personality match

Another study on personality has found that people may be better off in cities which match their personalities.

Dr Wiebke Bleidorn, who led this study, said:

“Individuals low on openness to experiences had significantly lower self-esteem in open cities, like New York City, but relatively higher self-esteem in cities that score relatively lower on openness to experience, for instance, Tuscaloosa, Alabama.”

In other words, people may have higher self-esteem when their personality matches the city.

If you’re open-minded, you’re better off to live in an open-minded type of place.

Happy places

Some areas even seem to give off a special lustre of happiness which people are attracted to.

In a further study of life satisfaction and population growth, Richard E. Lucas found that happy places grow more quickly (Lucas, 2013).

He explained:

“This suggests that there is something about happier places that people recognize and that attracts people to live there.

It’s not clear from our research why this association exists.

It could be that people intentionally move to places that are happier, and the factors that attract people also contribute to happiness, or it may be that places that are growing feel more energetic.”

The 5 Happiest Countries And What Makes Them So Happy

Only one country in North America is amongst the world’s happiest.

Only one country in North America is amongst the world’s happiest.

Switzerland is the world’s happiest country, according to the 2015 World Happiness Report.

The next four spots are taken by Iceland, Denmark, Norway and Canada.

The United States came in 15th spot, while the UK is at 21 and Australia at 10.

Unsurprisingly, four of the five least happy countries in the world are in sub-Saharan Africa: Rwanda, Benin, Burundi and Togo.

The three countries that have seen the biggest gains in happiness are Nicaragua, Zimbabwe and Ecuador.

The biggest drop in happiness is in Greece, where the economy has collapsed.

Jeffrey Sachs, Director of the Earth Institute, Columbia University, said:

“The aspiration of society is the flourishing of its members.

This report gives evidence on how to achieve societal well-being.

It’s not by money alone, but also by fairness, honesty, trust, and good health.

The evidence here will be useful to all countries as they pursue the new Sustainable Development Goals.”

The Gallup organisation surveyed people across 158 countries about their happiness.

They found that most of the differences in happiness could be explained by six factors:

  • Real GDP per capita,
  • healthy life expectancy,
  • having someone to count on,
  • perceived freedom to make life choices,
  • freedom from corruption,
  • and generosity.

Professor Richard Layard, Director of the Well-Being Programme at LSE’s Centre for Economic Performance, and one of the study’s editors, said:

“A positive outlook during the early stages of life is inherently desirable, but it also lays the foundation for greater happiness during adulthood.

As we consider the value of happiness in today’s report, we must invest early on in the lives of our children so that they grow to become independent, productive and happy adults, contributing both socially and economically.”

The study also found that long-established social norms were important to national happiness.

People were happier when they could rely on family, friends and social institutions.

Professor John F. Helliwell, of the University of British Columbia and the Canadian Institute for Advanced Research, and another of the report’s editors, said:

“As the science of happiness advances, we are getting to the heart of what factors define quality of life for citizens.

We are encouraged that more and more governments around the world are listening and responding with policies that put well-being first.

Countries with strong social and institutional capital not only support greater well-being, but are more resilient to social and economic crises.”
