Insomnia hazards
Physiological experiments have shown that people who lack sleep not only have a significant decrease in immune function, but also have 4-5 times the daily aging process compared to normal people. The following article systematically explores and studies the impact of sleep on physiological tissues:
1. Sleep and cell lifespan
The consequences of lack of sleep on cellular oxidative renewal mainly lead to tissue damage, which is repaired through the action of enzymes. Continuous repair between molecules and the overall maximum lifespan of cells are inseparable. In terms of aging, the most important thing is to detect DNA damage and repair them, and the integrity of cells is the foundation of their division and proliferation lifespan, And this repair mechanism is completed during deep sleep in living organisms.
Scientific research experiments have shown that high intensity sleep time is the most powerful force that the average body spends on repairing DNA damage. In terms of cellular molecular science, this balance between DNA damage and DNA repair is the most important indicator of Cellular senescence.
2. Sleep and body immunity
Whether it is a lack of sleep or a lack of complete sleep, it is a devastating blow to the human immune system, with the thymus gland rapidly shrinking. This is the most important immune organ in the human body. Normally, only in the middle and old age will the thymus shrink to the size of a cherry, while the proliferation of T cells will significantly decrease. Not only will white blood cells and lymphocytes be greatly reduced, but macrophages will also have an inhibitory effect.
Without the protection of the immune system in the human body, the threat of various carcinogenic diseases to the human body can be said to be fatal. Even in the short term, the human body may feel nausea, dizziness, mental atrophy, and limb weakness, which is not only a physiological trend of a direct decline in immunity, but also a precursor to diseases.
3. Sleep and nervous system
The nervous system is the main functional regulation system of the body, which directly regulates the functions of various organs and systems in the body, and sleep is closely related to the physiological role of the central nervous system,
As a regulatory mechanism, sleep is used to regulate visceral activity and hormone secretion through the hypothalamus, The neuroendocrine not only depends on the instructions of the central nervous system, but also is the activity cycle of the "Circadian clock" of life itself.
Physiologically, the Circadian clock is the memory code that DNA plays the role of heredity. The following thalamus tissue will secrete reducing glutathione, Superoxide dismutase (SOD) and so on from 10 o'clock to about at night when the human body is in deep sleep. These are non synthetic human essential hormones, which are mainly used to repair cell damage, promote cell proliferation and differentiation, and ensure the normal growth and development of various tissues and organs.
4. Sleep and repair mechanisms
Experiments have shown that even short-term sleep deprivation and lack of sufficient sleep time can lead to rapid aging and a significant decrease in the body's immune system.
Deep sleep at night, through the central nervous system of the hypothalamus, actually regulates the metabolic activities of various tissue cells to affect the physiological activities of the human body, mainly used to repair cell damage and restore the integrity of tissue function.

We sleep and cover ourselves with blankets every day. In the scorching summer, it is necessary to have a specialized summer blanket. In the summer, the blanket we cover should not only be stuffy but also have a warm effect. Compared to traditional cotton quilts, quilts specifically designed for summer use are lightweight and comfortable. Generally speaking, summer blankets are made of four types of materials: synthetic fiber, pure cotton, silk, tencel, down, and relatively thin towels. So, how do we choose a suitable quilt to cover in summer? The following aspects can serve as references: 1. Try to choose a cold color. For example, blue, light blue, purple, and other colors belong to cool tones. In the scorching summer, they can give people a sense of coolness to some extent and lower your psychological temperature.


Hotel supplies 4 knowledge: the Duvet cannot be squeezed, and the silk quilt must not be exposed to the sun!

The weather is gradually starting to change seasons, although the temperature may fluctuate between cold and hot, it is also necessary to prepare in advance for the storage during the change season. The storage of winter bedding is even more important. If the storage and organization method is not correct, be careful not to shorten the lifespan of the quilt. The following four common knowledge for storing winter bedding must be remembered. 1、 The Duvet can be exposed to the sun and cannot be washed Many people's favorite Duvet in winter should not be washed with water before storage. Washing will damage the down. If you want to clean it, you should give it to professional dry cleaning. Before storing the Duvet, it can be exposed to the sun, because it can increase the warmth and softness of the Duvet. On average, it can be stored after being exposed to the sun for 2-3 hours on both sides. 2、 Duvet can not be compressed in vacuum Before the Duvet is stored, it needs to be dried in the shade, or use a Dehumidifier to remove the humidifier, and then never use a vacuum compression bag, because it may break the down and affect the Fill power and warmth of the down. 3、 Wool should not be washed with water, and caution should be taken when exposed to sunlight Wool blankets cannot be washed or dried with water, as it may cause shrinkage and felting, damaging the scales of the wool and making it unable to keep warm. If you want to store it, you can first expose it to sunlight, but it only takes 1-2 hours, and excessive exposure is not allowed. 4、 Silk should not be exposed to sunlight or compressed before storage Because silk is a protein fiber, it should be avoided from direct sunlight exposure to prevent high temperatures from damaging the fiber structure and causing silk breakage. Before storage, dehumidification should be done first, and compressed bags should also be avoided to avoid silk breakage.

Cleaning of Duvet (1) When cleaning cotton fabrics, laundry detergent and other detergents (do not use bleach containing detergents) should be put into water first, and after they are completely dissolved, cotton fabrics can be added. (2) Generally, the soaking time should not exceed half an hour, and the water temperature during cleaning should not exceed 40 degrees Celsius. (3) When cleaning, light colored products should be washed separately from dark colored products to avoid staining. (4) When drying the quilt, it is advisable to choose a well ventilated and sunless place, with the best time from 10am to 3pm. It is best to remove the cover when drying.
