Sleep is the most relaxing time of the day and a crucial process for regulating the body. So how can you sleep healthily? Next, we'll introduce the top 10 misconceptions about sleeping positions.
1. Sleeping with an electric blanket on all night
Leaving an electric blanket on overnight not only leaves you feeling parched upon waking but also increases your risk of catching a cold.The ideal temperature inside the covers when falling asleep is 33-35°C (91-95°F), with relative humidity at 55%-60%. In this "microenvironment," the skin's blood vessels constrict, slowing blood flow and allowing the body to rest and recover fully.If the electric blanket heats for too long, causing persistently high temperatures under the covers, skin blood vessels dilate, blood circulation accelerates, breathing deepens and quickens, and resistance to pathogens decreases, making colds more likely. Therefore, the correct way to use an electric blanket is to turn it on 10 minutes before bedtime. Once the bedding is preheated, turn it off. It should be warm enough that you don't feel a sudden chill when getting under the covers.
2. Sleeping with hands under the head
Placing both hands under the head while sleeping not only impairs blood circulation, causing numbness and soreness in the upper limbs, but also increases abdominal pressure. Over time, this can lead to "reflux esophagitis."Poor digestion can impair overall nutrient absorption, leading to a sallow complexion over time.
3. Sleeping in drafts During sleep, the body's ability to adapt to environmental changes decreases. Sleeping in a draft makes you susceptible to catching a chill and falling ill. Therefore, avoid sleeping in drafty areas; keep your bed a reasonable distance from windows and doors.
4. Sleeping in a seated position
Many women, exhausted from demanding work, collapse onto the sofa after dinner and doze off. Sleeping while seated slows the heart rate, dilates blood vessels, and increases brain hypoxia, leading to dizziness and tinnitus.
5. Sleeping with Head Covered
Many people prefer sleeping with their heads covered, but this practice is highly detrimental to health. The exhaled oxygen poses significant harm to the brain. Those who habitually cover their faces with blankets risk breathing difficulties. As carbon dioxide levels rise and oxygen levels drop within the quilt, prolonged inhalation of humid air severely damages the brain.Over time, this can lead to oxygen deprivation, resulting in poor sleep quality and increased nightmares. Upon waking, individuals may experience dizziness, fatigue, and mental lethargy.This arrangement causes one partner to inhale mostly the other's exhaled air, depriving the brain of fresh oxygen or causing insufficient oxygen supply. This can also lead to insomnia, vivid dreams, and waking up feeling dizzy, weak, and mentally sluggish. Since everyone has different sleeping habits—kicking off blankets, snoring, etc.—it's easy for the blanket to slip off, causing you to catch a cold and disrupting sleep.
7. Sleeping with shoulders exposed
Some individuals habitually leave their shoulders uncovered while sleeping, unaware that cold air readily invades the shoulder joints. This can cause stagnation of qi and blood flow in local meridians and joints, leading to rheumatism, arthritis, and joint soreness and pain. Exposure to cold air also increases susceptibility to colds, runny noses, breathing difficulties, dizziness, and headaches.
8. Sleeping with jewelry on
Some women do not remove jewelry before bed, which is quite dangerous. Firstly, metal jewelry can cause long-term skin abrasion, leading to chronic absorption and potential accumulation of toxins (such as aluminum poisoning). Secondly, glow-in-the-dark jewelry emits radium radiation; though weak, prolonged exposure can have adverse effects over time.Third, wearing jewelry while sleeping impedes bodily circulation and hinders metabolism, which is also why the skin around jewelry tends to age prematurely.
9. Sleeping in a bra
Bras protect the breasts, but sleeping in one can invite disease, particularly breast tumors.Research indicates that women wearing bras for over 17 hours daily face over 20 times higher risk of breast tumors than those wearing them briefly or not at all. This stems from prolonged breast compression obstructing lymphatic drainage, causing harmful substances to accumulate in the breast tissue.
10. Falling asleep slightly intoxicated
With changing lifestyles, young women today often have active nightlife, especially career women with frequent social engagements, leading to falling asleep while slightly drunk. Medical research indicates that drinking before bed increases the risk of sleep apnea, typically occurring about twice per night with each episode lasting around 10 minutes.Over time, this habit increases susceptibility to heart disease and hypertension. Surprised by these findings? Understanding and correcting these improper sleeping habits is essential for maintaining good health! This concludes our exploration of the top 10 sleeping posture misconceptions. We hope this information proves helpful. Wishing you good health and smooth sailing this winter.
