Sleep, but a major event in life, according to the average sleep of 8 hours a day, sleep occupies almost 1 3 hours of people's lives. How can you make sleeping, an already comfortable thing, more enjoyable?
You might as well try sleeping naked!
Today, the family doctor will talk about the benefits of sleeping naked in detail, you will never think of it.
The experimenter has conducted an experiment using a sleeping bag and a thermometer.
Two experimenters (a man and a woman) first carried out a naked sleep test, lying still as much as possible within 1 hour, and recording temperature changes every 20 minutes. End result: The temperature change in the bedding was 31 in males9℃→35.2℃→35.5℃→35.6℃；The change in bedding temperature in females is 34 to 354℃→35.2℃→35.3℃。
Subsequently, they tested the temperature change of dressing and sleeping in the same way, and found inAfter 40 minutes, it began to decline, and in women it dropped to 35 .
It can be seen that sleeping naked is indeed warmer than sleeping with clothes. How does this work?
Professor Hu Guoliang of the School of Materials and Textiles, Zhejiang Sci-Tech UniversityExplain that the quilt itself is cold, and when a person sleeps naked, it will absorb the heat from the human body, thus warming itself. In this way, the temperature of the human body will naturally drop. However, after a period of time, the quilt has gained enough heat, and the human body continues to heat up, and the temperature of the quilt gradually rises, making people feel warmer and warmer.
In contrast, if you sleep in pajamas, the pajamas will suck up the body's heat, which will then be robbed by the quilt. As the heat is repeatedly conducted, there is more loss. Therefore, from the point of view of warmth, sleeping naked seems to be more advantageous.
When it comes to the benefits of sleeping naked, in addition to making people feel warmer, there are three other benefits.
The first is to improve the quality of sleep
The quality of sleep is related to how relaxed the body's limbs are, and the more relaxed the body, the easier it is to reach deep sleep. Therefore, it is important to choose a good mattress, pillows of the right height, and comfortable bedding.
Among them, the most direct contact with the body is pajamas. Excessively tight or heavy clothing will cause a certain sense of restraint to the body, which is not conducive to physical and mental relaxation; Pajamas that are too loose may be misaligned when they turn over, wrapping around the body and affecting breathing, causing dreams or waking up.
When sleeping naked, the body is able to get maximum stretch without any additional constraints, making the muscles more relaxed, which improves the quality of sleep.
The second is to improve gender relations
Studies have shown that in a stressful environment, a person's breathing, heart rate, and adrenocortical hormone levels can fluctuate significantly. Long-term stress that cannot be relieved can lead to a series of problems such as increased blood pressure and increased anxiety.
However, in stressful situations, if the subject is able to have skin-to-skin contact with his partner, the subject's heart rate, cortisol level and other indicators will be significantly reduced. This means skin-to-skin contact helps people feel soothed and stress released.
Third, it is more conducive to physiological health
Many people are prone to sweating during sleep, and if they are wearing pajamas, it is more difficult for sweat to be fully discharged, and at this time, ** will always be in a state of high humidity, which is relatively more prone to dermatitis diseases. And when you sleep naked, sweat is more likely to evaporate, and you can stay dry, which is better for your health.
In addition, people also need a proper naked sleeping environment. Because most of the time is wrapped in **, this humid and stuffy environment is easy to breed pathogens and induce infection. Therefore, proper "ventilation" can better protect the physiological health of **.
Seeing this, some people may be eager to experience sleeping naked, but some people may still be worried about hygiene.
In fact, sleeping naked in your own home or in a relatively safe environment is not a hygienic problem.
The human body's ** barrier system is very strong, and it will not easily contract ** diseases because of sleeping naked. If you think about it, our arms and legs are exposed to the air for a long time in the summer, and we don't inexplicably get sick because of this.
Therefore,As long as you do a good job of washing and changing bedding regularly, and maintain a relatively clean and dry sleeping environment, you can boldly choose to sleep naked.
ForProne to allergiesWhen sleeping naked, direct contact with bed sheets, sheets or exposure to the air is prone to allergic reactions such as rashes due to contact with dust or dust mites.
ForSuffering from hypertension, cardiovascular and cerebrovascular diseases, due to changes in external temperature, body temperature fluctuations may trigger, thereby inducing acute cardiovascular events.
In addition, it is not recommended to sleep naked in unfamiliar environments, such as hotels, other people's homes, etc. After all, there's no way to know for sure if something happened in bed.
