If the two most important things in a day are nothing more than "eating" and "sleeping".
An unhealthy diet that "gets sick from the mouth" can affect physical health. However, substandard sleep quality can also affect physical health. Sleeping not only relieves our fatigue of the day, but also promotes detoxification of the body. It is also possible to prepare for the new day and guarantee good condition on day 2.
Relevant data show that sleep and disease have a certain relationship, and people who have been in sleep deprivation for a long time are more likely to suffer from cardiovascular and cerebrovascular diseases and liver diseases.
Why does sleep deprivation affect health?
01 Sleep deprivation is prone to obesity
After research, it has been found that habitual staying up late and gaining weight have a certain relationship, and people who lack sleep/ people who often stay up late are more likely to get fat, why? Mainly in the case of lack of sleep, the consumption of energy becomes faster. At this time, people often feel hungry, and can't help but find food to replenish the energy needed by the human body, which causes us to become fatter and fatter.
02 Sleeping time is too short and prone to heart disease
Long-term lack of sleep also has a certain damage to our heart. Mainly because when people are lacking sleep, there will be memory weakening, the brain is in a state of chaos, resulting in the body's metabolism suffered a certain impact, this time there may be abnormal heartbeat, blood rise and other phenomena. When the heartbeat and blood pressure are in an unstable state for a long time, it will cause a series of complications, such as: cardiovascular disease, heart disease and so on.
03 Long-term lack of sleep can lead to endocrine disorders
Sleeping can not only replenish the spirit, but also promote the regulation of the balance of the human endocrine.
When we are in a state of lack of consciousness for a long time, the metabolic function and endocrine of the human body will be in a state of disorder, and if we continue like this for a long time, it will cause a series of "failures"; Even some women will stay up late, their faces will become dull, bursting and so on.
I don't know if you have noticed that when you sleep, you will always unconsciously put your feet outside the quilt, and you will often be frozen when the weather is cold.
Why do you unconsciously put your feet outside when you sleep?
In fact, putting your feet outside when you sleep can promote the quality of sleep. Studies have found that when the quilt is covered, the body surface temperature will slowly increase. When the human body is at 21-24 °, it is most suitable for sleep, and exceeding this temperature will affect the quality of sleep. Putting the foot outside the bed is actually to cool the body, which is a subconscious action to ensure the quality of sleep.
Will this affect your health in the long run?
Not really.
First of all, when we sleep, our feet are like "air conditioning", and when the body temperature is too high, we will unconsciously put our feet outside the quilt. When the temperature of the body drops to a temperature suitable for sleep, our feet will involuntarily retract.
Secondly, for people with better resistance, the current weather, not covering the quilt at night, the impact on the body will not be too large, let alone only put the feet outside. If we are worried that if we leave our feet outside and the cold will invade our bodies from the soles of our feet, we can wear a pair of socks while sleeping.
According to the relevant data of the "White Paper", staying up late and having difficulty falling asleep has become a norm. 44% have sleep disturbances, and 42% of older adults sleep for more than 30 minutes.
What causes severe insomnia?
Excluding insomnia caused by human factors (long-term use of mobile phones, circadian clock disorders), frequent insomnia may have a certain relationship with liver disease.
First of all, when it comes to the main task of the liver, everyone first thinks of the detoxification function of the liver, in fact, the liver not only needs to eliminate the toxins of the body weight every day, but also assumes the role of "bank", which can store our blood in the liver, thereby promoting the secretion of bile and protein, so that the human body's function can reach a balanced state.
Secondly, if we often stay up late, it will cause harm to the human liver in the long run. Because from 11 p.m. to 3 a.m. is the process of liver detoxification and repair.
If we choose this time point to stay up late, it may affect the liver's self-repair and detoxification effect, making the liver function worse and worse. This can cause liver damage.
Studies have found that the health of the liver has a certain relationship with sleep, and when liver function is abnormal, the quality of sleep will also be relatively poor; Conversely, people with normal liver function will have a relatively better sleep quality. At the same time, when we sleep, we put our legs outside, which not only has the effect of cooling down, but also likes to put our feet outside the bed when the liver detoxifies at night.
Summary: Although putting your feet outside the bed can protect the liver and promote sleep, you must control the temperature. Especially the indoor temperature at night, try to keep it at about 22 ~ 24 ° C, so as to ensure that when we put our feet outside, we will not freeze.
