How many days can you last with only 2 hours of sleep a day?

There are only 2 hours of rest time a day, and it depends on the patient's constitution, those with good constitution can last more than 20 days, and those with weak constitution can only last 2 or 3 days.

Sleep plays a vital role in the body, allowing the body's various systems to get enough rest, and normal adults need 7 to 8 hours of sleep a day to ensure normal work and study.

Sleeping only 2 hours a day can last for several days, this problem is related to personal physique.

If you only sleep for two hours a day and feel obviously unwell or lack of energy, you should rest quickly, and you can't brace hard, even if you have a good physique, your body will completely collapse and enter the hospital in a month. In general, it is not possible to sleep only two hours a day. If you can't sleep at night due to an emergency, napping can indeed restore a lot of energy, but if you don't sleep at night, you can't just rely on napping to support you!

Studies of brain waves and other physiological indicators have shown that biorhythms are biphasic rather than polyphasic, which determines that our bodies always tend to sleep in one whole block. Attempts to reduce the total amount of sleep by taking multiple short naps can reduce the duration of different stages of sleep, disrupting biological rhythms, and ultimately causing negative effects similar to sleep deprivation and sleep rhythm disorders, such as decreased physical and mental function, increased anxiety and nervousness, and decreased immune function.

People with weak physique may not be able to hold on for two or three days, and those with a particularly strong physique may last for more than 20 days, but this will hurt the body so much that they will go to the hospital. Of course, there are many people who have a special physique, and it doesn't matter if they don't sleep at night, but after all, this kind of person is in the minority, and ordinary people only sleep for two hours a day and sooner or later their bodies will collapse. The sleep limit of ordinary people is to sleep four hours a day, but this does not mean that everyone can sleep only four hours a day, if you only sleep two hours a day and feel obviously unwell or lack of energy, you must rest quickly.

There are 1 3 hours of time in a person's life to be spent on sleep, and there are different optimal sleep times for different ages, and the average minor needs at least 9 10 hours of sleep a day (the specific growth stage is different, see below for details), adults have 7 to 8 hours of sleep a day, and the elderly have 5 to 6 hours of sleep a day.

1.For minors, getting enough sleep is essential for physical development. Specifically, 16-20 hours of sleep are needed in infancy, 10-14 hours in early childhood, and 11-12 hours in preschool.

In addition, minors have a large demand for nutrients, so they should pay attention to the intake of sufficient protein, fat and nucleic acids.

2.Adults generally get seven to eight hours of sleep. Good sleep and sufficient sleep time are the guarantee of learning and work efficiency. You should pay attention to staying up less late and exercising more, go to bed early and get up early, and develop good sleep and exercise habits.

3.Older people generally sleep for a shorter period of time, and five or six hours of sleep are sufficient. The elderly should maintain a regular work and rest, a reasonable diet and a good attitude to ensure good health.

Total sleep time includes naps, and generally half an hour to an hour nap helps improve energy in the afternoon and contributes to good health. However, excessive napping should be avoided, which may cause discomfort such as headache and swelling after waking up, and can also easily induce difficulty falling asleep at night.

As an adult, it's usually just an hour, but I sleep relatively lightly and wake up easily, so I usually only sleep for an hour and squint for about half an hour at noon.

Many people believe that the more they sleep, the more energetic they will be. In fact, those who sleep more are not because they need to sleep for a long time, but because they do not take good care of their sleep system, which causes this system to be weakened and cannot work efficiently.
