How many hours of sleep do you get every night? Well, the numbers can vary, some say 5 or 6 hours and some say 7 or 8 hours. There are many people who believe that it is enough to sleep 6 hours.
However, researchers at the University of California, San Francisco, say that it is only bad news to only sleep six hours, as this can lead to chronic sleep deprivation.
As a result, you may feel depressed, have difficulty paying attention, and reduce the ability to control your appetite. According to the National Sleep Foundation, healthy adults and the elderly should be given at least 7 to 9 hours of sleep per night for various body functions to function optimally.
Why is sleep important?
Sleep is important for many reasons – it signals your body to release hormones and compounds that control your hunger levels (beneficial for mid-night snackers), maintains your immune system, lowers the risk of health problems and preserves memory.
How sleep seven to eight hours positively affects your body
1.Manage your appetite
If your sleeping habits are poor, this can increase the body’s energy needs. This will activate your brain to release chemicals to signal hunger. This ultimately leads to more food and more weight. Researchers in a study revealed that people who slept for more than 8.5 hours had a higher body mass index (BMI) and higher A1C values. A1C is a measurement of a person’s normal blood sugar level. And those who slept for 6.5 hours had the lowest A1C levels.
2.Supports immune function
While you sleep, your immune system releases compounds called cytokines that are important for signaling the cells. Some of these cytokines have a protective effect on the immune system by helping against inflammation and various types of infections. If your sleep is not enough, the immune cells are unable to produce enough cytokines that will prevent you from getting sick. A 2013 study found that a bad night’s sleep increases the amount of inflammatory substances in a person’s body. These compounds are responsible for triggering asthma and allergies. The study researchers also found that people who sleep four to five hours a night have a weak immune system.
3.Increases your life span
The researchers from Italy and the United Kingdom analyzed data from 16 separate studies that were conducted over 25 years, involving nearly 1.3 million people and more than 100,000 deaths. Their research results were published in the ‘Sleep’ magazine. The findings revealed that people who just slept six hours a night increased their risk of premature death by 12 percent. And those who slept for eight to nine hours had a much lower risk. 10 Insurance schemes Started by Modi insurance schemes launched by Modi Govt 10 Bollywood actors who have successful additional activities!
4. Helps with memory function
In addition to regulating immune function and appetite, good sleep also helps protect and strengthen your memory. Research shows that sleeping well can be an aid in saving memories. And people with poor sleeping habits have a harder time retrieving information, they can interpret events differently and lose the ability to access previous information. It is also essential to experience all sleep stages that contribute to creative thinking, long-term memories and memory processing.
5.Risk of diseases is reduced
If you have a lack of sleep, you can increase the risk of health conditions such as diabetes, heart disease, obesity and obstructive sleep apnea. And all of these health conditions can be kept at a distance when you sleep at least seven to eight hours.
