One personality trait is linked to understanding other people’s feelings.

Being agreeable is linked to high levels of empathy, research finds.

Agreeableness is one of the five major aspects of personality, along with conscientiousness, neuroticism, openness to experience and extraversion.

Agreeable people tend to be tactful, trusting, friendly and warm.

They are generally mindful of other people’s feelings, which also makes them more compliant.

People who are agreeable are more likely to be helpful to others, because of their propensity for empathy.

The conclusions come from a series of studies in which people read scenarios describing a person getting into difficulties.

Subsequently, they rated how much empathy they felt and whether they would offer assistance.

The results showed that the more agreeable people are, they more they felt empathy for the victim of the story.

Agreeable people were more likely to offer their assistance.

Along with agreeable people, those who were more neurotic were more likely to empathise.

Dr Meara Habashi, the study’s first author, said:

“It is common for persons to experience distress on seeing a victim in need of help.

That distress can lead some people to escape, and to run away from the victim.

But distress does not need to block helping because it may be one first-appearing aspect of empathy.

Distress can actually contribute to helping, but the way it contributes depends on personality.”

Less agreeable people seem to need more reminders that they should help out, said Dr Habashi:

“Personality matters.

It matters in how we structure our request for help, and it matters in how we respond to that request.

Helping is a result of several different processes running in sequence.

Each process contributes something different.

The way we ask for help -perspective taking — can influence our chances for getting it.”

The study was published in the journal Personality and Social Psychology Bulletin (Habashi et al., 2016).

People with higher IQ have this cheerful quality.

Feeling happy and satisfied is linked to having a higher IQ, research finds.

In fact, experiencing positive emotions, feeling lively and wide awake all predict higher intelligence.

The conclusions come from two studies of 440 people who completed tests of personality and well-being/happiness.

When given a task to do, people with higher intelligence were less stressed both before and afterwards, as well as being more engaged, researchers found.

People who were happier and more lively were also more likely to agree with statements like:

• Am quick to understand things.
• Have a rich vocabulary, and intellectual engagement.
• Like to solve complex problems.

Positive answers to these questions matched up with an actual fluid intelligence test they were given.

In other words, smart people were right about being smart, they didn’t just ‘feel’ smart.

Fluid intelligence refers to the speed at which the brain works.

It is like the raw power of an engine or the speed at which a computer can process information.

The study’s authors conclude:

“The results indicated that Intellect was generally associated with lower stress (low distress and worry and high task engagement) before and after intelligence tests.”

Even without being given a test to do, people with higher IQs felt happier and more energetic.

The reason that IQ and happiness are linked could be down to how much importance is placed on being smart in Western cultures.

The authors write:

“It is striking that Intellect was correlated with affect even in Study 1, in which there was no requirement to perform an intellectual task.

At least in Western cultures, intellect may be of sufficient importance to the self-schema that it influences general emotional functioning.”

The study was published in the journal Personality and Individual Differences (Zajenkowskia & Matthews, 2019).

It increases relationship satisfaction and marriage solidity.

One of the simplest ways to improve your relationship is to enjoy more hugs and cuddles, research finds.

Couples who experience higher levels of non-sexual touch are more satisfied with their relationships.

Men, in particular, felt more satisfied with their relationships when they were shown more routine affection.

For women, affection through touch was still important, but low levels were linked to relationship dissatisfaction.

Ms Samantha Wagner, the study’s first author, said:

“There’s something specific about touch satisfaction that interplays with relationship satisfaction but not dissatisfaction for wives.”

The study included 184 couples who were interviewed about their relationship and how much affection they routinely showed towards each other.

The results revealed that more affection was linked to better relationships.

On top of this, couple’s satisfaction with non-sexual touch was also linked to having a more solid marriage.

Ms Wagner said:

“Interestingly, there’s some evidence that holding your partner’s hand while you’re arguing de-escalates the argument and makes it more productive.”

However, Ms Wagner warned that not everyone appreciates being touched.

Touch can mean different things to different people and in the wrong context can constitute abuse.

People with autism, for example, can find touch overwhelming.

Still, most people find touch comforting, especially in times of stress, said Ms Wagner:

“Feel free to give some extra snugs on the couch.

There’s plenty of evidence that suggests touch as a way to decrease stress.”

The pandemic has meant that many people cannot be as close to their loved ones as they would wish.

Healthcare workers, for example, may be quarantining themselves from their families.

Ms Wagner said:

“I think we should all hold the loved ones we can a little closer and be thoughtful of the struggles that others might be having because they can’t do just that.

If anything is true for me, a hug has become even more precious than it was before.”

The study was published in the Journal of Social and Personal Relationships (Wagner et al., 2020).

It could be possible to increase your IQ.

Young adults who are fitter have a higher IQ and are more likely to go on to higher education, research finds.

Higher IQ is linked to a higher heart and lung capacity, not to muscular strength.

Heart and lung capacity was most strongly linked to verbal comprehension and logical thinking skills.

Professor Michael Nilsson, one of the study’s authors, said:

 “Being fit means that you also have good heart and lung capacity and that your brain gets plenty of oxygen.

This may be one of the reasons why we can see a clear link with fitness, but not with muscular strength.

We are also seeing that there are growth factors that are important.”

The researchers found that the link is down to environmental factors, not genes.

In other words, it could be possible to increase your IQ by getting fitter.

Dr Maria Åberg, the study’s first author, said:

“We have also shown that those youngsters who improve their physical fitness between the ages of 15 and 18 increase their cognitive performance.

This being the case, physical education is a subject that has an important place in schools, and is an absolute must if we want to do well in maths and other theoretical subjects.”

The conclusions come from a study of 1.2 million Swedish men doing their military service, who were born between 1950 and 1976.

Another study have shown that two hours of extra physical activity per week can boost children’s performance in school (Käll et al., 2014).

Children doing more exercise doubled their chances of hitting national learning goals in that study.

The study was published in the journal Proceedings of the National Academy of Sciences (Aberg et al., 2009).

Survey of almost 30,000 people finds one personality trait consistently linked to longer life.

Being positive has been linked to living longer by research.

People lived longer if they were more:

• optimistic about the future,
• closer to other people,
• decisive,
• and felt more useful and relaxed.

Those who scored in the top sixth for being positive were 18% less likely to die over the next four years.

Other key factors linked to living longer included getting married and having a degree.

The results come from a survey of 28,662 people.

Both people’s mental health and their medical records were examined by the survey.

The people analysed in the survey had similar levels of physical health, income and other demographic characteristics.

Income, perhaps surprisingly, did not have an effect on the chance of dying.

Dr Christopher Jacobi, the study’s author, said:

“The results indicate that better positive mental health seems to have a somewhat protective effect against mortality.

In research literature the most frequently stated ways in which positive mental health is likely to affect mortality are via direct physiological responses such as lowered blood pressure, capacity to cope with stress, less drinking and smoking, an active lifestyle, and better sleep quality.

Likewise, people with high positive mental health might not be affected as severely by potentially negative symptomatic and physiological effects of life events like divorce or unemployment.”

Previous research has also revealed that both extroverts and optimists are more likely to live longer than introverts and pessimists.

As I wrote previously:

“Optimists have healthier hearts than pessimists, a study of over 51,000 adults finds.

Optimists also had healthier body mass indexes, were more physically active and less likely to smoke.

Researchers found that the more optimistic people were, the greater their overall physical health.

The most optimistic people were 76% more likely to have health scores that were in the ideal range.”

The study was presented at the British Sociological Association’s Medical Sociology conference in Birmingham on 8 Sept 2016.

It is linked to higher relationship satisfaction, more positive relationship behaviours, better mental, physical health and even better health behaviours.

Using the pronouns “we” and “us” is linked to having a healthier and happier relationship, research finds.

Couples who use “we” and “us” are signalling their interdependence.

Talking like this means a couple are more likely to be closer in how they think, feel and act.

It also suggests they can rely on each other for support.

Interdependence is particularly important at times of stress and conflict.

The conclusion comes from an analysis of 30 studies including a total of over 5,000 people.

Mr Alexander Karan, the study’s first author, said:

“By examining all these studies together, they let us see the bigger picture.

We-talk is an indicator of interdependence and general positivity in romantic relationships.”

The results showed that ‘we-talk’ was linked to higher relationship satisfaction, more positive relationship behaviours, better mental, physical health and even better health behaviours.

Mr Karan said:

“The benefit of analyzing many different couples in a lot of different contexts is that it establishes we-talk isn’t just positively related in one context, but that it indicates positive functioning overall.”

The question, said Dr Megan Robbins, study co-author, is what comes first, the ‘we-talk’ or a good relationship:

“It is likely both.

Hearing yourself or a partner say these words could shift individuals’ ways of thinking to be more interdependent, which could lead to a healthier relationship.

It could also be the case that because the relationship is healthy and interdependent, the partners are being supportive and use we-talk.”

The study was published in the Journal of Social and Personal Relationships (Karan et al., 2018).

Fluid intelligence refers to the raw speed at which the brain works.

A hunger for new, unconventional ideas is one of the strongest indicators of high IQ, research finds.

People with high IQs are intellectually curious and enjoy things like unusual activities, philosophical arguments and brain teasers.

This desire for new ideas is linked to an aspect of IQ called fluid intelligence.

Fluid intelligence refers to the speed at which the brain works.

It is like the raw power of an engine or the speed at which a computer can process information.

Fluid intelligence is contrasted with crystallised intelligence.

Crystallised intelligence is something like general knowledge: the information that people have learnt about the world over the years.

The conclusions come from a study of 2,658 employees working at 10 different companies in the UK.

They were all given tests of personality and intelligence.

The results showed that high fluid intelligence was linked to hunger for new ideas.

Like an interest in ideas, being willing to try new activities was also linked to intelligence, the authors write:

“Actions refers to willingness to try different activities, and to a preference for novelty and variety over familiarity and routine.

Fluid intelligence involves things like reaction times, quick thinking, reasoning, seeing relationships and approaching new problems.

This means that individuals high on [fluid intelligence] have an innate ability to cope more efficiently with novel experiences, and to deal with intellectually stimulating tasks such as brain teasers, which would thus make it rewarding for them to pursuit such activities.

Similarly, individuals low on [fluid intelligence] may in time grow to avoid such activities, due to their low ability to handle them, which would thus make them less rewarding.”

The study was published in the journal Learning and Individual Differences (Moutafi et al., 2006).

An ingredient in sugar-free and low-calorie foods that could increase the risk of heart attack and stroke.

Erythritol is a sugar substitute made from wheat or maize and commonly used as an additive in foods and medications.

According to a study, consumption of erythritol over the long-term could increase the risk of heart attack and stroke.

Over 4,000 European and American adults took part in the study.

The researchers noticed that participants with elevated levels of erythritol in their blood samples were more likely to suffer from heart failure, stroke, or other major adverse cardiovascular events (MACE), and death.

To identify why this sweetener has such an effect on human health, the team examined the changes made by erythritol in the blood and isolated platelets.

Platelets are small blood cells that clump together to form clots when a blood vessel is damaged.

They found that erythritol increased platelet reactivity and the formation of blood clots (thrombosis).

Past studies have also suggested that erythritol ingestion would increase blood clotting.

Dr Stanley Hazen, the study’s senior author, said:

“Sweeteners like erythritol, have rapidly increased in popularity in recent years but there needs to be more in-depth research into their long-term effects.

Cardiovascular disease builds over time, and heart disease is the leading cause of death globally.

We need to make sure the foods we eat aren’t hidden contributors.”

In recent years table sugar has been extensively replaced with erythritol or other artificial sweeteners in low-carb, low-calorie, and keto meals.

People with diabetes, obesity, or metabolic syndrome or those who want to lose weight have been advised to eat sugar-free foods which often contain erythritol.

However, these people are at increased risk of adverse cardiac events such as heart failure and stroke.

Erythritol is a natural sweetener largely made from fermenting corn and it is 70 percent as sweet as sugar.

Erythritol when ingested can’t be eliminated easily from the body, alternatively, it will be absorbed into the bloodstream and some passes through urine.

Our body naturally makes a very small amount of erythritol but its long term consumption will only lead to accumulation of this compound in the body.

The other issue is that artificial sweeteners are difficult to measure and minimum labelling requirements are applied to these ingredients.

In addition, The United States Food and Drug Administration (FDA) has listed erythritol in the ‘Generally Recognized As Safe’ (GRAS) group meaning there is no need for specific research to evaluate its long-term safety.

Dr Hazen said:

“Our study shows that when participants consumed an artificially sweetened beverage with an amount of erythritol found in many processed foods, markedly elevated levels in the blood are observed for days—levels well above those observed to enhance clotting risks.

It is important that further safety studies are conducted to examine the long-term effects of artificial sweeteners in general, and erythritol specifically, on risks for heart attack and stroke, particularly in people at higher risk for cardiovascular disease.”

The study was published in the journal Nature Medicine (Witkowski et al., 2023).

Study tests if diet or exercise is better for maintaining weight loss.

The best way to maintain weight loss in the long-term is through more exercise rather than less food, research finds.

People in the study maintained weight loss of 30 pounds or more for around ten years by being active.

They did more physical activity and expended more energy each day than those who were obese.

Successful weight loss maintainers did around 12,000 steps each day, compared with 6,500 by obese people.

In other words, successful weight loss maintainers ate more but burned it off through exercise.

Your activity levels matter a lot more than what you eat in the long term, the researchers concluded.

Dr Danielle Ostendorf, the study’s first author, said:

“This study addresses the difficult question of why so many people struggle to keep weight off over a long period.

By providing evidence that a group of successful weight-loss maintainers engages in high levels of physical activity to prevent weight regain — rather than chronically restricting their energy intake — is a step forward to clarifying the relationship between exercise and weight-loss maintenance.”

The study compared successful weight loss maintainers with one group of people with normal body weight and another group who were obese.

Successful weight loss maintainers did twice as many steps as people who were obese, the results showed.

Exercise clearly beat restricting calorie intake for maintaining weight loss.

The results are the same as those from an analysis of people who had been on the reality TV show “The Biggest Loser”.

Again, people who maintained their weight loss did so through increased activity.

Changes in diet had little effect on maintaining weight loss over the years after they finished the show.

Dr Victoria A. Catenacci, study co-author, said:

“Our findings suggest that this group of successful weight-loss maintainers are consuming a similar number of calories per day as individuals with overweight and obesity but appear to avoid weight regain by compensating for this with high levels of physical activity.”

The study was published in the journal Obesity (Ostendorf et al., 2019).
