A common complaint that increases brain aging, unless treated.

High blood pressure, at any age or for any duration, accelerates brain aging, a study finds.

People with high blood pressure are at greater risk of memory problems and difficulties concentrating and talking fluently.

Around half of all Americans have high blood pressure, which is simply treated with a combination of lifestyle changes and medication.

The cut-off for high blood pressure is around 120 to 130 mmHg (this is the top number on the reading).

Sometimes this range is known as ‘prehypertension’, but the study still found this level damaging to cognitive skills over time.

High blood pressure is problematic for young and old, explained Professor Sandhi M. Barreto, study co-author:

“We initially anticipated that the negative effects of hypertension on cognitive function would be more critical when hypertension started at a younger age, however, our results show similar accelerated cognitive performance decline whether hypertension started in middle age or at older ages.

We also found that effectively treating high blood pressure at any age in adulthood could reduce or prevent this acceleration.

Collectively, the findings suggest hypertension needs to be prevented, diagnosed and effectively treated in adults of any age to preserve cognitive function.”

The conclusions come from an analyses of over 7,000 people in Brazil who were tracked for almost four years.

The results showed that people’s cognitive skills declined if their blood pressure was over 121 mmHg and they did not take medication.

People with uncontrolled hypertension showed the worst declines in thinking skills.

Professor Barreto said:

“In addition to other proven benefits of blood pressure control, our results highlight the importance of diagnosing and controlling hypertension in patients of any age to prevent or slow down cognitive decline.

Our results also reinforce the need to maintain lower blood pressure levels throughout life, since even prehypertension levels were associated with cognitive decline.”

The study was published in the journal Hypertension (Teles De Menezes et al., 2020).

Empathy for certain emotions helps couples have difficult discussions about change, research finds.

Direct communication is the best way to get your partner to change, research finds.

Whether it is getting them to lose weight, spend less money or change life goals, being more direct is the best approach.

Naturally, these sorts of discussions are fraught with difficulty.

The emotional tone of the communication is vital.

Be empathetic

One key to having difficult discussions is empathy.

Research shows that people with stronger relationships tend to be better at reading the emotions of embarrassment, shame and sadness in their partner.

Couples who perceived these softer negative emotions more clearly tended to be more satisfied with their relationships.

In contrast, those who were better at spotting stronger negative emotions, like anger and contempt, had weaker relationships.

Dr Bonnie Le, the study’s first author, explained the reason:

“If you are appeasing with your partner — or feel embarrassed or bashful — and your partner accurately picks up on this, it can signal to your partner that you care about their feelings and recognize a change request might be hurtful.

Or if your partner is angry or contemptuous — what we call dominance emotions — that signals very different, negative information that may hurt a partner if they accurately perceive it.”

Reading embarrassment and shame

The study included 11 couples who had dated for an average of three years.

They were asked to discuss what aspects of their partner they wanted to change.

Naturally, this raised some strong emotions which the researchers asked the couples about after the discussion.

This procedure simulates a common way of dealing with relationship conflict: by asking your partner to change.

The results showed that couples able to read emotions like sadness, embarrassment and shame had stronger relationships.

This is probably because being able to read these emotions helps difficult discussions — like those requesting change — to go more smoothly.

However, reacting more strongly to anger and contempt likely derails difficult discussions early on.

Professor Stéphane Côté, study co-author, said:

“We think reading emotions allows partners to coordinate what they do and say to each other, and perhaps that is helpful when appeasement emotions are read, but not when anger emotions are read.

Anger seems to overpower any effect of reading emotions, which is consistent with lots of research findings on how anger harms relationships.”

Direct communication is the best way to get a partner to change.

It must be done sensitively, though, said Dr Le:

“It’s not bad to feel a little bashful or embarrassed when raising these issues because it signals to the partner that you care and it’s valuable for your partner to see that.

You acknowledge that what you raise may hurt their feelings.

It shows that you are invested, that you are committed to having this conversation, and committed to not hurting them.

And the extent to which this is noted by your partner may foster a more positive relationship.”

The study was published in the journal Psychological Science (Le et al., 2020).

How your sense of humour, what time you go to bed and your curiosity reveal your intelligence.

Being curious, staying up late and having a dark sense of humour are all signs of a high IQ, psychological research finds.

People who are curious ask lots of questions, look for surprises, seek out sensations and make time to search out new ideas, a study finds.

Intelligence, along with curiosity and some personality factors, predicts successful performance in many areas.

Night owl

Being a night owl, meanwhile, is linked to stronger reasoning and better analytical and conceptual thinking.

Night owls prefer to stay up late at night and rise later in the morning.

Around one-third of the population are night owls, with one-quarter preferring to rise early.

The remainder fall somewhere in between, being neither early risers nor late sleepers.

Dark humour

Liking dark humour is a sign of higher intelligence, research finds.

Dark humour, the study’s authors write, is:

“…a kind of humour that treats sinister subjects like death, disease, deformity, handicap or warfare with bitter amusement and presents such tragic, distressing or morbid topics in humorous terms.

Black humour, often called grotesque, morbid, gallows or sick humour, is used to express the absurdity, insensitivity, paradox and cruelty of the modern world.

Characters or situations are usually exaggerated far beyond the limits of normal satire or irony, potentially requiring increased cognitive efforts to get the joke.”

Surprisingly, though, people who like dark humour feel the least aggressive towards others.

In other words, it is not aggressive people who like sick jokes.

Dark humour, it seems, is more difficult to enjoy without higher intelligence.

The study was published in the journals Perspectives on Psychological Science, Personality and Individual Differences & Cognitive Processing (Díaz-Morales & Escribano, 2013; von Stumm et al., 2011; Willinger et al., 2017).

Two servings a day of this high-fat food could lower diabetes risk and reduce high blood pressure.

Eating more whole fat dairy is linked to a lower incidence of diabetes and hypertension, a study has found.

Having dairy products twice a day in your regular diet reduces the risk of high blood pressure and diabetes, the risk factors of Metabolic syndrome.

Diabetes, hypertension, and obesity together will lead to metabolic syndrome, a disorder that puts people at higher risk of heart disease and stroke.

Past studies suggest that higher consumption of dairy products  reduces the odds of high blood pressure, diabetes, and so metabolic syndrome.

This study suggests that full-fat dairy foods but not low-fat dairy have the strongest effect on lowering the incidence of metabolic syndrome and its related risk factors.

To test if this is true for populations in different countries, researchers included 21 countries on five continents.

Participants were between 35- and 70-years-old and the average follow-up was over nine years.

Dairy intake was either low-fat (1–2%) or whole-fat, including mixed dishes prepared with dairy ingredients, milk, yogurt, cheese, yogurt drinks, butter, and cream.

Average diary intake was 179 grams (g) per day, with whole-fat dairy intake counting almost twice as much as low-fat.

The standard serving and portion sizes were used, for example, 5 g for one teaspoon of butter, 15 g for a slice of cheese, and 244 g for a cup of yogurt or a glass of milk.

Compared with eating no dairy, two servings a day of dairy foods reduced the risk of metabolic syndrome by 24 percent and for whole-fat diary by 28 percent.

The likelihood of developing diabetes and hypertension was reduced up to 12 percent.

The risk was reduced to 14 percent with a dairy intake of 3 servings per day.

The authors concluded:

“If our findings are confirmed in sufficiently large and long term trials, then increasing dairy consumption may represent a feasible and low cost approach to reducing [metabolic syndrome], hypertension, diabetes, and ultimately cardiovascular disease events worldwide.”

The study was published in BMJ Open Diabetes Research & Care (Bhavadharini et al., 2020).
