Still using the alarm clock to wake up! Aren’t you afraid of changes in your body?

Human sleep has its own inherent mechanism, and waking up naturally is in line with the laws of the human body's biological clock. Light is a necessary condition for waking up naturally and is the biological alarm clock in the human body. In the early morning, the human body feels the gradually strong sunlight, the secretion of melatonin decreases, the secretion of serotonin increases, the metabolism speeds up, and people gradually transition from deep sleep to light sleep until waking up.

The fast-paced modern life prevents many office workers from enjoying a leisurely sleep and natural awakening, so the alarm clock becomes a helpless choice. However, experimental studies have shown that the physiological and psychological effects of waking up naturally and being woken up by an alarm clock are very different.

When transitioning from sleep to wakefulness, a person's breathing will increase from 16 times/minute to 24 times/minute, the heart rate will increase by 10 times/minute, and brain waves will increase from 8 times/second to 30 times/second. If you are suddenly woken up by an alarm clock, you will feel anxious, depressed, sleepy and suspended, etc. If you are suddenly awakened from deep sleep, your short-term memory, cognitive ability, and even calculation skills will be significantly affected; these abilities are at most 65% of the normal state, so being awakened by an alarm clock is equivalent to being drunk.

Being frequently woken up by an alarm clock can also be harmful to your health. The sudden sound of the alarm clock will trigger the body's protective conditioned reflex and increase the level of adrenaline in the body. If this state continues for days, weeks, or months, it will lead to high blood pressure, sleep problems, and mental depression.

This is because during sleep, the human body undergoes some changes that make people more susceptible to illness in the morning, and the alarm clock will exacerbate this process.
