Few people can get up on time without an alarm clock, but there are such people. What is their secret?

Some people easily wake up on time even without an alarm clock, while others cannot. This is partly due to the biological clock, the balance of rest and work, as well as the state of a person's health. Thanks to the biological clock, a person wakes up at the same time.

At the same time, various factors can affect the biological clock. This is nutrition, temperature at different times of the year, lighting, caffeine, etc. Ideally, a person's biorhythms should work stably. However, if he often stays up late and if he lacks self-discipline, he may also wake up at the same time in certain situations. This is explained by stress.

That is, those who wake up at the same time without an alarm clock may simply suffer from an increased level of stress.
