There is such an amazing difference between sleeping enough for 8 hours and not sleeping enough for 8 hours

It is estimated that no one in the world has a deeper understanding of the pain of insufficient sleep than novice mothers. With long-term intermittent sleep and serious lack of sleep, Xiaojiu, who could barely be called beautiful, has now completely become the aunt of 39 Xiaojiu.

How bad is it? Here, just like the picture below.

It is needless to say that Xiao Jiu has become very grumpy now with dark circles under his eyes and fine lines. My biggest dream is to sleep until dawn, and then count the benefits of sleep in my dream and giggle

1. The hematopoietic function of spleen and bone marrow is improved.

The spleen and bone marrow are the hematopoiesis system of the human body. If a person stays up all night, the hematopoiesis function of his body system will be reduced by 20%, and if he stays up all night, it will be reduced by 40%. Therefore, long-term staying up all night and insufficient sleep are important factors leading to anemia.

2. Not easy cold

According to a study published in the journal Sleep, people who sleep less than 6 hours a day have a four times higher risk of catching a cold than those who sleep more than 7 hours.

Through a follow-up survey of 164 volunteers, researchers at the University of California, San Francisco found that compared with those who slept more than 7 hours a night, those who slept less than 6 hours a night had a 4.2-fold higher risk of catching a cold, and those who slept less than 5 hours a night had a 4.5-fold higher risk of catching a cold.

3. Better athletic ability

Exercise can help improve sleep. On the other hand, when you don’t get enough sleep, it will be difficult to exercise, so you can’t exercise vigorously and for a long time.

Xiao Jiu said that she felt the same way. Even though she was already overweight, she could not bring up the idea of exercising to lose weight in her mind. Whenever she had time, she just wanted to find a bed to lie down and sleep.

4. Decreased appetite

Hormones in our bodies constantly create hunger and satiety. Experiments show that these hunger hormones – ghrelin, leptin and insulin – are destroyed when sleep is interrupted. In addition, the study also found that when people lack sleep, their hunger will greatly increase, and they are more inclined to choose junk food with high calories.

According to a survey by Boston women and children’s Hospital, compared with teenagers who sleep more than 8 hours, teenagers who sleep less than 8 hours a night get 2.2% more calories from fat and 3% less calories from carbohydrates; And for every additional time of sleep, the probability of eating a large number of snacks will be reduced by 21%.

5. Treatment migraine

According to a South Korean study, lack of sleep, fatigue and excessive stress are the three major triggers of migraine. Another study published in the journal headache shows that when women get enough sleep, migraine symptoms decrease.

6. Reduce diabetes risk

American scientists divided the sleep time of a day into three categories: sleep less than 6 hours, sleep between 6 and 8 hours, sleep more than 8 hours. They observed the impact of sleep time on blood sugar. During the six-year study, it was found that those who slept less than 6 hours a day had a 4.56 times higher proportion of blood sugar changing from normal to abnormal fasting blood sugar than those who slept between 6 and 8 hours. There was no difference between those who slept more than 8 hours and those who slept between 6 and 8 hours. It can be seen that patients with diabetes who sleep less than 6 hours every night are prone to abnormal fasting blood glucose.

In addition, researchers from the University of Chicago found that if healthy adults sleep an average of 316 minutes (about 5.2 hours) a day, they will secrete 50% more insulin after eight consecutive days than those who sleep 477 minutes (about 8 hours) a day. As a result, people who slept less had a 40% decrease in insulin sensitivity.

7. Better shape

Whether it is children or adults, many studies have shown that there is a great correlation between insufficient sleep and obesity. First of all, people who are lack of sleep and drowsy definitely don’t like sports, and then eat more. Secondly, the lower metabolic rate also plays a role.

8. Appearance will become younger

A 46 year old British woman named Sarah Chalmers took part in an experiment at a sleep school in London. The following is a comparison of her face when she slept only six hours for five consecutive days and when she slept eight hours.

(8 hours on the left and 6 hours on the right)

The reason why our skin is soft and shiny is that it relies on the capillaries of the subcutaneous tissue to provide sufficient nutrition. Insufficient sleep will cause stagnation of skin capillaries and blocked circulation, so that skin cells can not get sufficient nutrition, thus affecting skin metabolism, accelerating skin aging, and making skin appear dark and pale.

9. Improved immunity

The proliferation quantity and activity of human immune cells (lymphocytes, leukocytes, B cells, etc.) will be greatly reduced due to lack of sleep. Studies by special institutions in the United States have found that if people only rest for six hours for three consecutive days, their immunity will be reduced to only 20% of the original.

10. Intelligence improvement

A person’s brain must think clearly and respond sensitively, and must have enough sleep. If you don’t get enough sleep for a long time, your brain won’t get enough rest, which will affect your brain’s creative thinking and ability to process things.

Therefore, we must cultivate regular work and rest time. Avoid staying up late, exercise more during the day, reduce caffeine intake after noon, smoke less, drink less, and create a good sleep environment, which can help you live a full sleep.

However, people like Xiao Jiu who are suffering from insomnia are another story.
