Circadian rhythms is in all living organisms on our planet. They control the intensity of various biological processes such as hormone production. Often circadian rhythms are tied to the alternation of day and night, but our body including very well able to adapt to daily routine, “remembering” their biological clock when we get up and when to go to bed.
A big role in changing the cycle “sleep-awake” plays protein PER1. When its level in the body decreases, our heartbeat slows down, and the pressure and temperature drops. This is what happens during sleep. Upon waking the next level, “acceleration” biological processes of the body – we feel more cheerful.
Unexpected awakening by the alarm clock is always stressful for the body. To make it at least a little less, the body begins to adjust circadian rhythm of PER1 protein production under the time alarm bells. So our body tries to make for himself the early morning Wake-up stress is not so strong: even in my sleep gradually increases heart rate, blood pressure, hormones rise. Over time, the brain is so precisely adjusted to the time of awakening, that we open our eyes for a few minutes before the alarm.
