Although it is not the most common gesture right now, the handshake is one of the most universal greetings. But beyond its symbolism, the handshake is very revealing about our own health.

A report from the BBC explains that currently, researchers are able to know the strength of a person, know the rate at which he ages and even diagnose certain health problems such as heart disease and cancer.

Grip strength is measured with a dynamometer. The evaluated person grasps it as they would hold a glass, with the elbow to the side and positioned at a right angle. It is squeezed for five seconds, three times with each hand. Then the stocking is taken out.

According to studies, men between 20 and 30 years are those who have more strength in the hand, while women of more than 75 the least.

The average grip in people between 20 and 29 years old is 46 kilograms of strength in men and 29 kilograms in women. When the person reaches between 60 and 69 years, the force drops to 39 Y 23.5 kg, respectively.

Heart disease

According to doctors, a lower than average grip strength (within the same gender and age range) is associated with an increased risk of cardiovascular failureas a lower force indicates harmful changes in the structure and functions of the heart.

Cancer

On the other hand, the force of a handshake also serves to anticipate the cancer survival. One study claims that lung cancer patients were more likely to overcome the disease if their grip was strong.

The study also points out that the diagnosis of cancer colorectal, prostate or lungn in men and breast or lung in women it is reflected in a reduction of five kilograms of force in the hand in people between 60 and 69 years.

Obesity and diabetes

The weak grip is also related to the obesity it is also associated with a more fragile grip, since the presence of fat around a muscle reduces its effectiveness.

Another recent study shows that people with type 2 diabetes They have a weaker handshake, also due to the accumulation of fat.
