How is too much sleep harmful to health?

Sleeping too much or too little can also cause the body to gain weight. A recent study found that people who slept 9-10 hours a night were 21% more likely to be obese than those who slept 7 to 8 hours, even if you eat less and exercise regularly.

2. Feeling exhausted all the time

Not only does sleeping a lot do not make you feel refreshed and full of energy. On the contrary, you will feel tired and not want to do anything.

The recommended amount of sleep is between 7-9 hours for adults. If you sleep more than that, your brain will always be in a state of rest and unable to focus.

Lack of sleep can cause headaches, and if you sleep too much, the same can happen.

Because researchers have found that when you sleep too much, some neurotransmitters including serotonin are completely reduced. That puts pressure on the brain and nerves, so you often have a headache when you wake up.

In the long run, too much sleep can lead to frequent neurotransmitters being mis-stimulated, causing you to oversleep. Furthermore, if you suffer from snoring, you are more likely to wake up with a headache.

When we sleep, especially for long periods of time, we often close the door to avoid light and noise. However, if this action continues for a long time, it will lead to insufficient indoor air circulation.

Long periods of time in a closed room without air will produce harmful bacteria, leading to poor air quality. In addition to sleeping for too long, people are very susceptible to respiratory diseases.

Many studies have found that people who sleep more than 9 hours a night have a significantly higher mortality rate than those who sleep 7 to 8 hours.

Although there is no specific reason for this conclusion, the researchers found that depression and low socioeconomic status caused people to sleep more, leading to complex disease progression, increased mortality rates, and more. death.
