For adults, getting 8 to 0 hours of sleep per day is ideal. Depending on the individual's needs, the amount of sleep will change accordingly.

Many people will find that there is a difference between sleeping only six hours and sleeping a full eight. If the body does not get enough sleep, it will have an impact on health. So, what is the difference between people who sleep eight hours a day compared to those who only sleep six hours?

1. Cardiopulmonary function

Studies have shown that people who sleep eight hours a day have a 20% lower chance of developing cardiovascular and cerebrovascular diseases, because the heart beats slower during sleep at night, and if you sleep enough, you can get enough blood to your heart to prevent irregular heartbeats.

In addition, people who sleep for six hours have less adrenaline secretion in their bodies than those who sleep for eight hours, which predisposes to the dysfunction of the heart, leading to the appearance of various acute symptoms.

In addition, sleeping eight hours a day can strengthen the body's immunity and improve the resistance of the lungs. Many lung diseases are caused by bacterial infections, so getting eight hours of sleep a day can prevent lung diseases from occurring.

Moreover, ensuring eight hours of sleep a day can fully discharge toxins from the lungs, enhance the function of the alveoli, and in the long run, the lungs are less prone to pneumonia, lung cancer and other problems.

Especially for smokers, they should ensure eight hours of sleep, because the alveoli in their body are less than normal, and ensuring eight hours of sleep every day can play a certain role in regulating lung function.

2. Mental state

Studies have shown that sleep can improve a person's sense of well-being, so getting eight hours of sleep a day not only improves productivity, but also keeps the brain excited and makes it easier to stick with it when things get tough.

In addition, when the body gets enough sleep, it can relieve tension in life and prevent depression, anxiety and other problems. If you work hard, you should get enough sleep, so that you can complete your work tasks more efficiently and quickly.

And if you only sleep six hours a day, the brain can't get enough rest, and brain cells are susceptible to damage, which can lead to memory loss and poor mental state.

Not only that, lack of sleep can also lead to decreased concentration, make people's mental state worse, and easily lead to the appearance of various mental diseases. If you already have this condition, it is recommended to seek help from a psychologist and carry out psychological treatment in time to prevent the condition from worsening.

3. Skin

Lack of sleep can affect how healthy your skin is, and if you only sleep six hours a day, your skin will age faster than someone who sleeps eight hours.

Moreover, long-term lack of sleep will slow down the blood circulation in the body, and the toxins in the body cannot be discharged normally, which can easily lead to pigmentation.

Therefore, in daily life, it is necessary to ensure sufficient sleep, so that the skin can become smoother and more delicate, and the complexion will be better and better.

To sum up, for patients with chronic diseases, it is more important to ensure adequate sleep. In the state of sufficient sleep, the body's immunity can be qualitatively improved, and the body has a greater chance to eliminate diseases, so as to obtain a healthier body.

因此建议每晚11点左右入睡，早上七点醒来，这样可以保证身体得到八小时的充足睡眠。
