《柳叶刀》研究：握力是健康的信号

A person with weak hand strength may be more likely to die.

This is what scientists have found.

In 2015, they measured hand strength in 17 countries.

They measured more than 139,000 people in total.

Four years later, they found one thing.

For every 5 kilograms less hand strength, the chance of death is 16% higher.

There is a scientist in the United States named Brian Clark.

He studies the human body at Ohio University.

He says the flesh on the body is called muscle.

Muscles do not move by themselves.

It is the brain that gives the order, and then the muscles move.

To grip something with the hand, 39 muscles are used.

These 39 muscles must work together.

In 2024, some elderly people were invited.

They measured the elderly people's hand strength.

Elderly people who think slowly also have weak hand strength.

There is also a scientist in Belgium named Ivan Bautmans.

He studies what happens to the body as people age.

He says that weaker hand strength is not a good thing.

It may be that the brain is going to have problems.

Measuring hands is cheap and fast.

So measuring hands can remind people early to go see a doctor.

There is one more thing: the two hands are different.

Most people have one hand stronger than the other.

About 10% stronger — this is normal.

If the difference between the two hands is too big, there is a problem.

He says if one hand has only half the strength of the other hand.

This may mean the body is deteriorating faster.

Weak hand strength does not mean you are definitely sick.

It just reminds people to go to the hospital early and get checked.

This June, Bautmans looked at 60 studies.

These studies included 380,000 people.

People with strong hands had a 19% lower chance of later cognitive decline.

There are also studies saying that strength training is also good for the brain.
