A phenomenon that seems strange, but is quite understandable.
Sometimes we wake up at 3 am. What could be the reasons for such an awakening, experts told, informs Ukr.Media.
Phases of sleep
Human sleep consists of successive phases that repeat several times during the night. Doctors believe that waking up at the end of a certain phase is a completely normal phenomenon.
Hormonal background
Hormones also play a significant role in the sleep process. Their level changes in cycles. Women are more susceptible to these fluctuations because it is related to their monthly cycles. Men also have their own cycles associated with the production of certain hormones, but they last longer than women.
Problems and stress
One of the reasons we can wake up at three o'clock in the morning is anxiety and stress. As a rule, this is observed in people who are always under tension.
Cortisol and melatonin are actively secreted in the body from the third to the fourth hour. In such people, the level of stress hormones is already high, and they can wake up due to the additional "injection".
Physical discomfort
In addition, physical discomfort can prevent you from sleeping. Bright lights, loud noises, an uncomfortable bed, or alcohol before bed can cause you to wake up.
