Can alarm clocks also threaten our health? Multiple alarm clocks make people fall into a "sleep swamp"

China Science and Technology News Network, February 17 (Jin Xi) Do you rely on a series of alarm clocks to wake up every day? After setting multiple alarm clocks, you always feel weak and listless after getting up? Recently, a netizen shared his experience of being "scared" by the alarm clock that comes with his Apple phone and feeling dizzy and vomiting. The doctor diagnosed him with transient cerebral ischemia. What impact will the alarm clock have on us?

Studies have shown that people who are awakened by alarm clocks have higher blood pressure and faster heart rate than those who wake up naturally. This is because the sound of the alarm clock is an "external stimulus" to the human body. The sudden sound will trigger the body's stress response, causing the body to secrete adrenaline and cortisol, leading to a variety of reactions. For example, pupil dilation, tracheal dilation, faster heartbeat... The body enters a defensive state and is under a comprehensive pressure.

If you have a chronic cardiovascular disease, long-term and repeated stimulation will put pressure on your cardiovascular system, increasing the risk of high blood pressure and heart disease complications. A loud and irritating alarm can also easily scare people, causing vasoconstriction, speeding up the heartbeat, and inducing or aggravating heart disease, cerebral arteriosclerosis, myocardial infarction and other diseases.

Although the alarm clock can ensure that you are not late for work, in the long run, it will bring huge pressure, leading to insomnia, high blood pressure and mental depression. Further investigation also shows that being woken up by the alarm clock also has a certain impact on people's short-term memory.

If an alarm clock has this kind of power, what about a string of alarm clocks?

After repeated awakenings, the adenosine content in the body increases, making people feel more sleepy and more likely to fall into a "sleep-wake" cycle, which may lead to chronic fatigue. Over time, after getting up, you will feel weak, dizzy, and lack of energy.

If you want to get up "painlessly", you can choose soft music, or natural sounds such as birdsong, running water, etc. as your alarm clock, and try to lower the volume to gradually wake up your brain in the morning and reduce the pressure of getting up. Or put the alarm clock farther away from the bed, so that when the alarm rings, it forces you to get up. When you walk over to turn off the alarm clock, you may realize that you have already gotten up.

You can also use light to your advantage by opening the curtains when you wake up, or even leaving them open overnight so that natural light can slowly filter in during the morning. Light stimulates the photoreceptors on the retina and sends wakefulness signals to the brain.
