How is too much sleep harmful to health?

A good and enough sleep every day is really essential. However, sleeping too much can cause unpredictable harm to human health.


1. Obesity

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.

3. Easy to get headaches

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.

So you should not spend "full time" of your day off in bed to "grill" if you don't want to wake up on Monday morning in a sluggish state, with a headache.

4. Weakness in both body and mind

About 15% of people with depression tend to sleep a lot. This makes the condition worse. According to scientists, regular sleep habits are very important for the recovery process.

Regularly sleeping too much aggravates chronic depression and many other physical problems such as back pain, hip pain, etc. In addition, if you tend to have shortness of breath at night (also known as “ sleep apnea”), you may stay in bed longer due to poor sleep quality.

This will weaken your heart muscle, increasing your chances of cardiovascular disease.

5. Becoming irritable

Waking up tired and realizing that you're not as productive as you'd like to be can take a toll on your mood, becoming irritable and irritable.

6. May have premature aging

Too much sleep not only makes your face and body age quickly, but also your "brain".

Too much sleep causes problems with memory and concentration. In addition, oversleeping slows down the metabolism and causes weight gain.

7. Memory loss

Some scientific studies also show that sleeping too much can also affect brain functions. It makes your brain age faster even older than 2 years.

Since then, the brain's activity is no longer agile, memory loss and significantly affect daily activities.

In addition, sleeping too much also makes it easy to fall asleep, or wake up in the middle of the night. This leads to poor sleep, poor sleep quality, so it affects the brain and health.

8. Vulnerable to respiratory diseases

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.

9. Circadian rhythm disturbances

Circadian rhythm disturbances occur when your body's circadian clock is out of sync with its natural day and night time schedule.

When you sleep too much, it can disrupt your circadian rhythm, making you sleep a lot during the day but lose sleep at night…

ten . High risk of death

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.
