I believe that many people’s alarm clocks are set like this:
6:20
6:30
6:35
6:37
……
However, the function of these alarm clocks is to be turned off again and again. Finally dragged it down, and then got up reluctantly with a tired face.
How to set the alarm clock so that you can wake up full of energy?
During lighter sleep cycles
Let the alarm go off
During the whole sleep process, from being awake to falling asleep, to being awake, in fact, there have been several sleep cycles in between. A sleep cycle includes NREM and REM periods.
It is not easy to wake up during the NREM period of deep sleep. If you wake up at this time, you will feel tired.
In the early morning REM period, it is easier to wake up. If you wake up at this time, people will feel better.
So the key to setting an alarm is: try to wake us up in the REM period.
Alarm clock setting rules
“Small first, then big 20 points”
Specifically, set 2 alarms, 20 minutes apart. The ringtone volume of the first alarm clock should be small and short, and the volume of the second ringtone can be slightly larger and longer.
For example, if you have to get up at 7 in the morning, you can set the alarm clock as: 6:40, 7:00, and the 6:40 alarm clock sounds lighter.
The reason for this is that in the early morning, the transition from deep sleep NREM to REM sleep takes about 20 minutes.
If you can be awakened by a small ringtone for the first time, it means that you are likely to be in REM sleep, which is easy to wake up. It is more comfortable to wake up at this time.
If you are not awake, it does not matter. It means that you are in a deep NREM period and it is not easy to wake up.
After 20 minutes, sleep will most likely enter a lighter REM period. The alarm clock rings for the second time, and it will be more comfortable to wake up at this time.
This is also the reason why the volume of the alarm clock was small and short for the first time. If the alarm volume is too loud, it may force you to wake you from the NREM period, and you will be very tired after waking up.
According to the statistical results under different conditions, this alarm setting method can increase the probability of waking up during the REM period to 1.5 times. It is still worth a try for everyone who has difficulty getting up.
