“The old quilt sleeps soundly” is a solid hammer! Research: Covering heavy quilts for 4 weeks can reduce the severity index of insomnia by 50%

“You are trying to harm me, hurry up and return my old quilt!”

It is said that the relationship between mother-in-law and daughter-in-law is the most difficult to get along with since ancient times. No, Lili was “picked up” by her mother-in-law again.

When Lili got married, she found that the quilt covered by her mother-in-law was still more than ten years old. Recently, the weather turned cold, and Lili was worried that her mother-in-law would be too heavy and warm under the quilt, so she thoughtfully replaced it with a light and warm silk quilt.

Unexpectedly, how long did my mother-in-law sleep? In the evening,didn’t sleep well and continued to suffer from insomnia,So I complained to Lili several times.

“I think that quilt is too heavy, and it’s not warm after covering it for so long.” Lili felt that she was thankless , the tone is also a little impatient.

The mother-in-law is also very anxious, “What do you know! The heavier the quilt, the better the sleep Hurry up and find a way to get it back for me.”

For a while, the two stalemate No less, the atmosphere is very tense. Lili stopped arguing and ran back to the room.

I have never heard that the heavier the quilt, the better the sleep. Isn’t the silk quilt not as good as the old cotton quilt? It must be her mother-in-law talking nonsense. The more Lili thought about it, the more wronged she became, and she couldn’t help crying.

On the market, there are duvets, silk quilts, Wool quilt… There are many types of quilts, and the texture is light, which is loved by many people. But there are also some people who prefer traditional quilts and think that “old quilts sleep soundly”. Is this an illusion or is there a scientific basis?

1. The heavier the quilt, the better the sleep? Look at the study

Recently, researchers in Sweden discovered , It is not an illusion to sleep more soundly under a large thick quilt.

The study found 26 healthy men and women of normal weight and non-smoking, and collected their data in the experiment< span>saliva sample. In the first trial, they were asked to cover themselves with a quilt that weighed 12.2 percent of their body weight, and in the second trial, they were put on a lighter quilt, about 2.4 percent of their body weight.

Through the Karolinska Sleepiness Scale found that cover thickness Scores were slightly higher when quilted, with higher scores indicating more sleepiness. More importantly, when the participants slept with a thick quilt, the concentration of melatonin in saliva increased on average about< /span>6.6±0.7pg/mL,significantly increased than when covered with a lighter quiltspan>32%.

Melatonin plays a key role in the sleep process and can effectively promote sleep. Therefore, research suggests that covering with a thick quilt will release more melatonin before going to bed, thereby improving sleep quality.

Researchers believe that the pressure generated by the thick quilt activates the sensory afferent nerves of the skin, It then travels to the “nucleus of the solitary tract” and finally projects to the paraventricular nucleus of the hypothalamus. The paraventricular nucleus contains small cell oxytocin neurons, which can affect the release of melatonin, and stimulate this area, can reduce feelings of fear, stress and pain< /strong>, which makes people feel more peaceful.

A study by the American Academy of Sleep Medicine also found that if you sleep with a quilt weighing 6-8 (kg), Only one month, the experimenter’s insomnia improvement rate can reach 59.4%, Insomnia severity index decreased by more than 50%, and anxiety and depression symptoms can also be relieved.

2. Reminder: The heavier the quilt, the better

Is it true that the heavier the quilt, the better? Of course not.

The quilt is too heavy, the greater the pressure on the person, the chest is under pressure,Reduces lung capacity. Moreover, too high bed temperature will also increase the body’s metabolic process, increase sweating, and make it easier to catch cold during sleep, making people fall asleep Feeling tired after waking up.

In addition, thick quilts are also easieraccumulate dust, may irritate the respiratory mucosa, and people with asthma or COPD may aggravate or relapse.

And when the quilt is too light The warming effect is relatively poor. When the body is stimulated by the cold, it will affect falling asleep, and may not sleep deeply.

The weight of the quilt is not constant, you need to considerseason. Generally speaking, it is recommended that the weight of spring and autumn quilts be between 1 and 1.5 kilograms, and that of winter quilts be between 3 and 6 kilograms, preferably not more than 8 kilograms.

3. Cotton quilts, silk quilts, down quilts, wool Being… which one is better?

This kind of quilt is especially suitable for people with sensitive skin and allergies. When choosing, it is recommended to choose a brand silk quilt and open the silk to see Whether the silk fiber is milky white or pearly white, and whether the silk will be easily broken or pilled when pulled.

2. Duvet

Down quilts are light, but have strong warmth retention properties, and have good moisture absorption and sweat permeation properties. The filling is usually goose down or duck down. If the down content is 50% The above is a high-quality duvet.

The advantage is that it is suitable for the elderly, pregnant women, children, and people suffering from high blood pressure, heart disease, and poor blood circulation , but the disadvantages are also obvious. First, in the room, small fluff tends to fall off, which may irritate the mucous membrane of the respiratory tract; second, because the duvet dissipates heat quickly, it often feels cold in the middle of the night.

3. Wool quilt

Wool quilt keeps warm , close fit, good moisture absorption and moisture release ability, suitable for people who sweat easily at night, or who like to kick the quilt. However, because wool will absorb the moisture and sweat emitted by the human body, it may feel very dry the next day, so it is not recommended It is suitable for people suffering from rheumatism.

4. Why does the quilt smell so good after drying?

Every time we finish drying the quilt, we can smell a “sun smell”Some people say that this is the smell after the mites are killed. The stronger the smell, the more dead mites are. Is this true?

A research team from the University of Copenhagen in Denmark found that Cotton towels emit a large amount of organic compounds such as aldehydes, ketones, and carboxylic acids containing 5-9 carbon atoms. When these substances are in low concentrations, they smell like the sun.

The reason why these compounds are produced may be that the ultraviolet rays in the sun will activate molecules such as disinfectants and softeners in the fabric and a small amount of free radicals , these highly active substances reactwith some components in the air, and finally show this taste,< strong>It has nothing to do with mites.

Nowadays, the weather is getting colder, and many people will take advantage of the sun to dry their quilts,Xiaomiao teaches you 3 techniques for drying quilts.
