How can I sleep well? These are the three things you need most.

Blindfold

Earplug

A comfortable bed

[can’t sleep at night, can’t get up during the day] [stay up late tonight for a while, get up tomorrow morning crematorium]…

No matter whether you do it yourself or are really forced to do nothing, people have one or two times when sleep quality is not high.

As a result, many people will turn to some sleep [artifacts] for help, hoping that these things can improve their sleep problems.

Sleep blindfolds and shading curtains, of course, have the greatest effect of shading the light and creating a [opaque] environment for the body. Then, the body secretes melatonin, and people naturally begin to feel sleepy.

Earplugs can help isolate external noise, make people fall asleep faster, and at the same time are less likely to be awakened by external sounds. If there is a snoring person nearby when sleeping, the effect of earplugs is highlighted.

Comfortable beds and pillows make you feel relaxed and comfortable when lying on them, and slowly fall asleep.

All these three things are enough? Where’s the sleep bracelet? Where’s the sleep candy? Where’s sleep music? Are these [sleep artifacts] useless?

For example, this sleeping water, which was introduced by a well-known beverage company in Japan and claimed to be “able to lie on the floor for 15 hours after drinking one bottle”, looks very attractive:

It’s easy to sleep for 15 hours at a time.

Don’t worry, let’s talk about these [artifacts] one by one.

Sleep water

Judging from the description of sleep water, the main active ingredient of this water is theanine.

Current human studies of theanine have proved that it can indeed reduce anxiety and improve sleep quality of ADHD children.

Careful examination of the topic, people improve the sleep quality of ADHD children. You are no longer a child, let alone ADHD, and you may not really be able to count on this bottle of water.

More importantly:

Existing human studies on theanine are based on small samples and short duration, and most of them are for children and young people.

Perhaps theanine has certain psychological effects, but the existing research is not sufficient to support its effect in advertising.

Fortunately, theanine has no side effects of what on human body. Those who want to experience it can give it a try with confidence.

Sleep candy, sleep buccal tablets, sleep stick

In addition to the magic [sleep water], there is also a kind of artifact used for [import], that is, all kinds of magic [sleep candy] [sleep buccal tablets]. Ding Dong also discovered a kind of seemingly magical [sleep stick]:

Sleep sugar

Sleep stick

The main active ingredient of this kind of products is melatonin.

Melatonin is a hormone secreted by light. Simply put, melatonin secretion starts to increase when it gets dark at night, so people are sleepy. At dawn, melatonin secretion begins to decrease.

Therefore, playing with mobile phones before going to bed will affect sleep. One of the most important reasons is that inappropriate light affects melatonin secretion.

For healthy people, melatonin supplementation is not necessary.

Long-term use of melatonin can also produce side effects, including drowsiness, hypothermia, etc. And melatonin will make you feel sleepy during the day, which is probably not what you want.

If you really have sleep disorders and feel that you may need melatonin and cannot use it indiscriminately, you must first listen to what the doctor says. If you are pregnant or a child, you should strictly limit your intake.

Sleep bracelet

At present, sleep bracelets sold on the market can be roughly divided into two types.

One claims to be able to detect sleep quality.

The principle of these bracelet products is to detect sleep quality by detecting people’s movement: assuming that people will have movements such as turning over in light sleep and less in deep sleep.

According to this assumption, sleep bracelets can roughly estimate the sleep situation of the human body.

However, this cannot be used as a standard, but only as a reference. The real standard that can detect sleep quality should be the EEG during sleep.

Blindly pursuing the data detected by these devices may not even dare to turn over because of anxiety and sleep worse. At that time, what’s the use of this data?

Another bracelet is a black technology that claims to be implanted with advanced chips, which can help improve sleep quality or speed up sleep. Ding Dang found a similar one on a well-known e-commerce website:

This product claims to be able to emit the so-called Schumann frequency to act on the human body, thus promoting sleep.

However, the [Schumann frequency] mentioned in this product promotion is not special to what. Simply put, it is the resonance flatness of our Earth’s atmosphere, which is 7.83 Hz. Similarly, when we blow into an empty bottle, we will also hear a sound with a fixed frequency.

Let’s do a simple math problem: the wavelength of the 7.83 Hz electromagnetic wave is about 380,000 kilometers, which is about the distance from the earth to the moon. However, the length (height) of a typical human body is 1.7 meters, and there is no possibility that any electromagnetic wave so large and weak will affect it.

Not only is it useless, it is also very expensive. For thousands of dollars, you can buy a shade curtain for the whole room.

Some people say, then I don’t have to spend money to buy these things, let me listen to some music. Is it useful to listen to music?

Bedtime music

For people who do have sleep disorders, bedtime music does help them sleep.

However, it is hard to say clearly whether listening to music is useful for healthy people who only occasionally feel that they cannot sleep well.

In research on sleep, the subjective feelings and reports of the tested people are generally used to evaluate sleep quality. This is the problem:

On the one hand, people’s subjective feelings are not accurate-they are usually not related to objectively measured data.

On the other hand, if subjective feelings are used for the experiment, there will be no real control group in the study, because all participants in the experiment know whether they listen to music before going to bed.

Therefore, if your sleep is not a big problem, just want to help yourself sleep better. Then the attitude towards sleep music can be: if you think listening is useful, then continue listening happily.

At the end of the day, most of these so-called sleep [artifacts] also come from psychological comfort.

Fortunately, in addition to melatonin needs to be used carefully, the rest of the few will not cause what damage to the human body. People who want to try and have economic strength can also try it boldly. It is said that the sleep water at the beginning is quite delicious.
