Why did you wake up five minutes before the alarm

Your body is the Service nenavidit



The internal clock of your body just as good, if not better, as the mechanical clock. In the center of the brain is the accumulation of nerves called the nucleus suprahiazmalnoe supervising body clock - the circadian rhythm. It defines the periods of sleepiness and vitality, control blood pressure, body temperature and a sense of time.

In fact, our body - perfectly tuned machine, and this machine likes predictability: the work of the body is most effective when there is a routine sequence. So if you fall asleep and wake up at the same time for several days, the internal clock adjust to this schedule.

Sleep-wake cycle is regulated by a protein PER. Protein level rises and falls throughout the day, reaching a peak in the evening and at night fall. When the PER is low, your blood pressure falls, heart rate slows down, and thinking becomes vague - you become drowsy.

If you wake up every day at the same time, the body learns to produce enough PER at the right time - about an hour before waking up with the level of PER body temperature and blood pressure begins to rise. To prepare for the stress of waking body produces a cocktail of stress hormones - cortisol.

That's why you wake up before the alarm. In fact, your body hates the Service - for it is a rude awakening is stress, shock. Alarm negates all the work of your body - it prevents it from waking up slowly, naturally.

By the way, if you do not wake up to an alarm clock, you probably will not fill up or go to sleep not on schedule. For example, if you get up at different times on weekdays and weekends, the "reset" setting of the internal clock. No schedule your body does not know when to wake up, so when the alarm goes off, you feel stunned and annoyed.

You press the snooze button, and because your body is awake, even under stress, subsequent REM sleep even more confuses the internal clock. Hormones that help you fall asleep, mixed with hormones that help you to wake up - the body is confused, and with each repeated wake-up call is only getting worse. So that morning trills - this is the worst way to start the day.
