We hear about the importance of sleep everywhere. Many manufacturers of furniture and especially mattresses advertise their products, maximally “sharpened” for a comfortable and healthy sleep. And everyone knows that one-third of each person’s life takes place in their dreams!
After just a few days without sleep, a person will begin to understand why sleep is so important. In addition to obvious signs, such as a feeling of constant sleepiness and fatigue, comes irritability, a deterioration in concentration, etc – symptoms that might not obviously point to poor sleep as the cause. A frequent lack of a healthy, extended sleep over time can affect immunity, libido, excess weight, and constant depression and has even been identified as a factor in the development of cancer.
How a lack of sleep affects health
It has long been known that quality sleep can help you to avoid many ailments, preventing the development of various diseases (cardiovascular, obesity, neuroses and depression). A lack of sleep can have a significant impact on human health.
For most adults, 7-8 hours of sleep is enough to rest and gain strength. The relationship between sleep and health is complex and still not fully understood; we can only say for certain that sleep deprivation can lead to severe depression, irritability, decreased concentration, fatigue, loss of energy, headaches, abdominal pain, memory loss and numerous other associated ailments.
The importance of sleep for normal human weight
To maintain optimal weight, a good sleep is invaluable. A long night’s rest protects your body from ailments associated with obesity. If you sleep less than the required time, your metabolism slows down. Lack of sleep can lead to a worsening of appetite, or vice versa, to raise the level of the hormone responsible for feeling hungry, which will lead to weight gain.
Why sleep is important for mental health
Do not underestimate the importance of sleep for the nervous system. Improving memory and the ability to focus can only occur if the body has a sufficient amount of sleep. While the lack of a night’s rest negatively affects emotional health, other effects include stress, irritability and lingering depression.
The negative effect of sleep deprivation on the body is best seen in a child, who will become restless, capricious, irritable. The same thing happens with adults, only less obviously so as they have greater control over their emotions.
The importance of sleep for the operation of organ systems
Every human body must sleep to function well. Without good sleep, the body experiences stress, which leads to certain health risks. Sleep deprivation, especially prolonged, can cause inflammation of internal organs which, when combined with stress, increases the risk of cardiovascular diseases, including hypertension and heart disease. Bad sleep can also lead to a violation of the immune system and an increased the risk of cold, flu, and other viral or bacterial infections.
There are also studies linking oncological diseases with quality of sleep. Some recent studies have shown that persistent nightmares, the lack of a full 8-hour’s sleep, night work, a sharp restless sleep in the middle of the night, and sleeping with the light on, all increase the risk of developing certain cancers, including breast cancer and colorectal cancer.
Believe it or not, the quality of your sleep also affects your teeth! Japanese scientists have found that people who do not have a sufficient amount of daily rest for several months or worse, years, progress more quickly to gum disease, as well as cardiovascular diseases. In those who report a high quality of sleep, such diseases were very rare.
I think you understand the importance of a good night’s sleep from this article. Do not neglect sleep, otherwise, it can be detrimental to your health!
