The explanation is given in the book. If you have that kind of thinking, you are still looking at the issue of sleep in isolation. You only see the sleep time every night, but you don't see a 24-hour repair process.
In fact, the time when you are about to go to bed and the time when you just wake up are also part of sleep, which is a repair process.
Chu Lihua learned in detail how to prepare before going to bed, and how to wake up the body after waking up.
Sometimes I have dinner with friends or colleagues, or because there are activities in the group at night, and it is after 10 o'clock when I get home. So how to use the r90 sleep plan to arrange time?
It's very simple. Chu Lihua determined that the time to get up in the morning is 6:30, and she plans to complete 5 sleep cycles. Then, if she calculates backwards, the ideal time is to go to bed at 11:00 in the evening.
But then she had just come home and there was no way she would be going to bed so soon. Then she will follow a 90-minute cycle, and wait until the next sleep cycle starts, that is, at 12:30 before falling asleep, so that she can complete at least 4 sleep cycles.
At first, Qing Yunfei still felt strange, if he went to bed an hour and a half later, he must be in a bad mood the next day.
¡ª¡ª"This question involves the arrangement before going to bed and after waking up. The preparation and actions before and after going to bed are actually as important as the time of falling asleep.
Sometimes even more important than falling asleep. Because this is your own time to control. Getting ready to fall asleep will directly affect the quality of your night's sleep.
Similarly, what you do when you wake up the next day can affect how you feel throughout the day. Ideally, you want a 90-minute acclimation period before bed and an equal amount of acclimation period after waking up. "
After Chu Lihua recounted what she had learned to Qing Yunfei again, she gained a deeper understanding.
Just like in the example just now, the composition of the 4 sleep cycles is not just 6 hours of sleep, but a repair process of up to 9 hours.
¡ª¡ª"There is another key question, what preparations should we make during the 90 minutes before and after sleep?
Let's talk about the time before going to bed first. This period of time is actually designed to allow you to fall asleep better.
Just like you eat very late, you can't go to bed right away, you must let the food be digested first.
Because according to the circadian rhythm, your brain will start to suppress intestinal activity from around 9 or 10 in the evening, which is not conducive to digesting food.
If you are still full at night, won't it disrupt the rhythm of your body and cause a burden? For another example, if you encounter some difficult problems at work, the high-load operation of the brain will also affect sleep.
Therefore, it is actually necessary to do something that helps you fall asleep before going to bed.
I also thought about a few things I can do before going to bed.
For example, you can tidy up your things. Prepare clothes for work or travel tomorrow. If we live at home, we can also do housework, wash dishes, wash clothes, etc.
For another example, you can take out a pen and paper, make a list, and write down all the things you are thinking about, all your thoughts, worries, and concerns.
In the process of writing, it is very relaxed and casual. It can also save you that irresistible factors will disrupt the plan and you will be in a hurry without countermeasures.
After finishing, put this list next to the keys, or other things that will be taken away the next day, and deal with these things tomorrow.
Doing this is also a hint to yourself. When you lie on the bed, you know very clearly that you have dealt with all the problems and can rest without any burden. "-
"Sounds good."
Qing Yunfei nodded thoughtfully.
¡ª¡ª"There is another small detail for you - you must breathe through your nose when you sleep."
¡ª¡ª"You are also asleep, how do you know that I am not breathing through my nose?"
As long as Qing Yunfei is mentioned, his rebuttal will always be the fastest.
Chu Lihua couldn't help laughing, and didn't argue with him, but just reasoned with him a little bit.
¡ª¡ª"Because you snore! Although I will get used to it after a long time, it will turn into a white noise similar to the sound of rain on a rainy night, and it can also promote my sleep. However, snoring is indeed harmful to your body not good.
British respiratory expert Patrick McKeown has a book on breathing through the nose called "The Benefits of Oxygen". It is mentioned in the book that breathing with the mouth will greatly increase the incidence of snoring and sleep apnea.
? Patients with sleep apneaOr, breathing stops repeatedly during sleep at night. At this time, the brain will send a signal of hypoxia to wake up the patient from sleep, which will seriously interfere with sleep.
This situation, I will also see in you, sometimes when your snoring is too loud, you will suddenly turn over or something, your sleep is interrupted by yourself, but you don¡¯t know it, so your Sleep quality will be poor. "
After Chu Lihua finished speaking to Qing Yunfei sincerely, Qing Yunfei paused and continued.
¡ª¡ª"No one has ever told me that I can snore before, how do I know if you lied to me?"
¡ª¡ª"If you insist on evidence, I can record it for you, but there is absolutely no need for it. In fact, you can feel it when you wake up.
How do you know whether you breathe through your nose or your mouth when you sleep?
It is also very easy to judge. Pay attention, if you wake up in the morning, if your mouth feels dry, it means that you breathe through your mouth at night; if your mouth is still moist, it means that you breathe through your nose. "
¡ª¡ª"Then snoring, many men have this problem, you can't even ask me to change this, right? It's not something I can control!"
¡ª¡ª"I don't mean to blame you, we should find a solution together when we encounter problems, we are a whole, instead of complaining to each other.
In fact, if you find that you are not breathing through your nose, don't worry, I also saw a solution in the book - use nasal strips.
That is, before going to bed, put on a nasal patch to expand the nasal passage, and then seal your mouth with a thin, hypoallergenic medical tape, so that you can gradually get used to breathing through your nose at night. "
¡ª¡ª"Are you sure you don't want to murder your husband? What if I just get bored like this?"
Qing Yunfei stared at Chu Lihua with terrified little eyes.
¡ª¡ª"Haha, what's the matter? Now you know you're afraid? You know you've done bad things a lot? Tell me, how many things are you sorry for me that you keep from me?"
Chu Lihua asked Qing Yunfei in a dark and sad manner on purpose.
¡ª¡ª"Where do I have any more! Now I have a deep understanding of what it means to be a hooligan who is not scary, I am afraid that hooligans will become educated. Make a big move quietly!" (Remember the website URL: www.hlnovel.com
