Under normal circumstances, you should feel energetic when you wake up in the morning and throughout the day. In the evening you must be exhausted from the fatigue of the day, right? But that’s not how it usually happens!
Bride The reasons for this contradiction let’s see.
We all have an internal alarm that tells us when to sleep and when to wake up. This internal clock is called the circadian rhythm and is 24 hours a day. It also helps the body and mind to oscillate between alertness and fatigue.
Ultimately, our bodies cannot function at all hours of the day. He needs time to listen and recover from the tension of the day.
A small part of the hypothalamus called the SCN, receives input from the environment, such as the time of dayThe SCN then sends signals to different parts of the brain to release or not release certain hormones.
Hormones and their levels also change during the day. Melatonin for example It is a hormone secreted towards the end of the day that causes drowsiness. It is only excreted when the body senses that the sun has set.
Cortisol, also known as the stress hormone, is also part of the circadian rhythm. cortisol level It starts to rise when you wake up and decreases towards the end of the day.
In short, circadian rhythm disruption appears odd for a number of reasons. You feel tired all day and energetic at night. Of course, all of this is determined by the state of the hormones.
