3, will make the body produce a series of physiological reactions. Serotonin is a neurotransmitter and a nerve inhibitor in the brain, which shields the cognitive pressure of the brain and makes people feel relaxed. Usually it secretes more during sleep, which makes us feel comfortable during sleep. However, serotonin is also a strong vasoconstrictor and a stimulator of smooth muscle contraction. Excessive sleep time leads to excessive serotonin, which leads to vasoconstriction and excessive nerve endings, which in turn leads to headache and prevents further sleep. This is the reason why I have a headache after sleeping too much.
How to get up quickly in the morning
Set the alarm clock to ring five minutes after it is turned off. Generally, when you wake up suddenly, it is difficult to fall into a deep sleep within five minutes. At this time, if the alarm clock rings for the second time, Bian Xiao believes that it is difficult for ordinary people to fall asleep again.
Put the alarm clock far away. If the first method still doesn't work for you who are sleepy, then put the alarm clock out of your reach before going to bed at night, preferably far enough away from the bed (of course, you can hear it). Then, when the alarm goes off in the morning, you can either keep it ringing all the time, but I believe it is difficult for anyone to go to sleep or get out of bed and turn it off. Now that you have got up and moved, you must be awake enough.
Suddenly lift the quilt. Obviously, this method only applies to winter. Give yourself this on a cold morning. Bian Xiao thinks you are absolutely refreshed.
