How much sleep does a day take to be healthy? How much sleep do you need a day to get healthy?

You need to get seven to eight hours of sleep a day. This will not lead to endocrine disruption and decreased resistance, which is good for health.

Personally, I think that 8 hours of sleep a day is fine, sleeping too short or too long will lead to low energy, and you can also drink a glass of milk before going to bed to help you sleep.

8 hours is just enough to keep you energized for the day.

Human sleep generally takes 4 to 6 cycles from falling asleep to waking up, and each cycle consists of five different sleep stages, which are:

Sleep onset, light sleep, deep sleep, deep sleep, rapid eye movement.

The time required for these five stages is usually 90-120 minutes, and it varies slightly from person to person.

4 to 6 cycles, that is, 6-9 hours.

When we wake up after a full sleep cycle, we are more energetic and awake than we were in the previous five stages.

And generally speaking, more than 4 cycles, we can get better rest.

In a cycle, even if you are awake, but the body does not get enough rest, you still have no energy and physical strength.

Sleep studies have shown that 6 to 9 hours is the right amount of sleep, while 7 to 8 hours is better.

People who sleep less than 5 hours are 52% more likely to have a heart attack than those who sleep 7 to 8 hours, and sleeping too much can also affect health.

Why is 6-9 hours of sleep healthy?

First of all, we are all familiar with the dangers of too little sleep.

Sleep deprivation can also lead to eating too much food, or making unhealthy dietary choices, which can lead to overweight and obesity, which in turn can affect heart health.

In addition, lack of sleep can also lead to a decrease in immunity and affect the brain's thinking.

Are there any dangers of sleep deprivation? Will it reduce immunity?

Studies have shown that adults who don't get 7-8 hours of sleep for 3 consecutive nights can have their immune function cut in half.

Generally, adults can maintain a sleep time of about 8 hours, but there is no mandatory requirement for sleep time every day, and it is generally based on their own situation. As long as you are in a good state of mind the next day, you will get enough sleep according to your needs.

People of all ages need different amounts of sleep. Generally, newborns sleep for about 18 hours; Babies are about 12 hours; Preschoolers sleep for about 10 hours; Adolescents sleep for 8-9 hours; 7-8 hours for adults; Older people may have their sleep reduced to about 6 hours due to various functional declines.

People with sleep disorders can drink a glass of warm milk before going to bed, and do appropriate physical exercise during the day to help them fall asleep, improve sleep quality, and ensure that the brain is fully rested.

With enough sleep, nerve cells and memory cells are likely to play their best role. If you don't get enough sleep for a long time and have poor sleep quality, it is easy to cause various health problems, such as mental weakness, sleepiness, malnutrition, etc. Therefore, in order to ensure good health and maintain high efficiency in daily work and study, adequate sleep time should be ensured.

If you only sleep 6 hours a day, what time should you go to bed and wake up to be more refreshed? 6 hours of sleep time is relatively not enough to meet the normal needs of the human body, it is recommended that such people should increase their work and rest time according to their own schedule, such as a proper lunch break at noon the next day, or increase sleep time at a certain time in the next half day.

The best time to go to bed at night should be to go to bed before 10 p.m., and in the morning to get up around 7 o'clock, because everyone should maintain 6-8 hours of sleep every day, ensuring adequate sleep time is a great benefit to physical health. We should pay attention to developing good habits of life and rest.
