Some "bad" habits that are good for your health

Not all bad habits should be completely eliminated. The article even lists some common habits of people, arguing that although they seem to be "bad habits", they are actually beneficial to the body as long as they are properly controlled.

Listen to heavy metal music

Studies have shown that listening to music with a strong sense of rhythm, such as heavy metal and hard rock, can actually stimulate the inner ear and brain in a positive way, making you feel happy. Just be careful, firstly, you need to choose a suitable environment for listening, and secondly, be sure to control the volume - the maximum volume that the human ear can withstand is 90 decibels. When a high sound of more than 100 decibels suddenly appears in the ear, it may instantly cause perforation and bleeding of the eardrum, and eventually lead to hearing loss.

angry

Being angry can increase your blood pressure. But compared to people who are not often angry, people who are often angry do not actually have higher blood pressure.

Playing video games

Some people believe that sitting still and playing video games for a long time not only affects eyesight, but also easily leads to obesity. However, when playing games, the player's heart rate accelerates and calorie consumption increases. As long as the length of time is controlled, it is a healthier form of entertainment than sitting and watching TV.

curse

Researchers say that swearing can actually relieve the pain felt by the swearer himself. Because swearing can stimulate the secretion of adrenaline.

Put pressure on yourself

Studies have found that short-term psychological stress can improve learning ability and memory. Stress causes the body to secrete the hormone cortisol, which has a positive effect on the hippocampus area of ​​the brain that controls learning. It is worth noting that people cannot handle high psychological pressure for a long time.

No housework

Earlier studies have shown that people who are exposed to kitchen fumes for a long time are more likely to have lung problems. Pregnant women who frequently use household detergents have a higher risk of giving birth to children with asthma.

Drinking carbonated drinks

The ingredients of Coke make people love and hate it. Research results show that drinking two cans of carbonated drinks a day can help prevent Alzheimer's disease and improve memory by up to 20%. But maintaining this habit for a long time may also lead to tooth decay and obesity.

Impatient

A study shows that people with quick tempers are more likely to be thin. This is because impatient people act quickly when they see any sign of trouble, so they naturally consume more calories.

Unhygienic

Studies have found that dust mites, which can trigger asthma, cannot survive in student dormitories that have not been cleaned.

gamble

A survey of people over 65 years old showed that those who gambled once a week were mentally healthier than those who never gambled.
