Often, in order not to oversleep, people set several alarm clocks one after the other. In the morning, they pull until the signal of the last of them and get up already exhausted. In fact, this approach can lead to health problems. For example, constant sleepiness will appear, and it will become more difficult to fall asleep, and the quality of sleep will worsen. Other consequences include insomnia, sleep apnea, and circadian rhythm disturbances.
Scientists from Harvard discovered that the hormone adenosine is produced in the body during such repeated awakenings. This leads to even more sleepiness, and the result can be chronic fatigue.
