1. Why is lack of sleep bad for your health?

Some people sleeping only 5 or 6 hours is not a good idea. There are many negative effects of sleep deprivation, such as feeling irritable and unable to function at your best. But many people may not know that sleep deprivation can also have profound consequences for our physical health?
According to statistics, one in three of us regularly suffers from insomnia and stress. Computers, electronic devices and busy work are the reasons given to explain this situation. However, the price to pay of all those sleepless nights is not only a bad mood but also a lack of concentration. Regular poor sleep puts us at risk for serious diseases, including overweight, obesity, metabolic cardiovascular disease and type 2 diabetes – the leading causes of our shortened life expectancy. It is now clear that a good night's sleep is essential to a long and healthy life.
Most of us need about 8 hours of sleep a night for our bodies to function properly - but many people can sleep less or more than this number. It's important to figure out how much sleep you need and then work to hit that time. As a general rule, if we wake up tired and spend the day hoping for a chance to take a nap, we're likely not getting enough sleep.
Many factors can cause poor sleep, including health conditions like sleep apnea. But in most cases it is usually due to bad sleep habits.
Sometimes a sleepless night will leave you feeling tired and cranky the next day, but it won't harm your health. However, after many sleepless nights, the effects on our mental health will become more and more severe. The brain will work inefficiently, making it difficult for us to focus and make decisions. Many people will begin to feel sad and may oversleep during the day. Our risk of injury and accidents at home, work and on the road also increases.
If this continues, lack of sleep can affect our overall health and make you more susceptible to serious conditions, such as obesity, heart disease, high blood pressure and diabetes. Here are 7 reasons why we should not fall asleep:

Prolonged lack of sleep can disrupt the immune system, so the body is less able to fight off foreign invaders. Sleep Can Stabilize Weight: Less Sleep Can Mean Weight Gain! Studies have shown that people who sleep less than 7 hours a day tend to gain more weight and have a higher risk of obesity than those who sleep 7 hours. This is thought to be because sleep-deprived people have reduced levels of leptin (the chemical that makes them feel full) and increased levels of ghrelin (the hormone that stimulates hunger). Sleep boosts mental health: A single sleepless night can leave us irritable and moody the next day, so it's not surprising that chronic sleep deprivation can lead to long-term mood disorders such as depression and anxiety. When people with anxiety disorders or depression were surveyed to calculate their sleep habits, it was found that most of them slept less than six hours a night.

Men with sleep apnea -- a disorder that makes it hard for them to breathe and disrupt sleep -- also tend to have lower testosterone levels and possibly a decreased sex drive.

Therefore, the recovery process will take a long time, even weeks. Starting on the weekend, try to get an extra hour or two of sleep each night. The way to do this is to go to bed when you feel tired and allow your body to wake you up in the morning.
Initially, you can sleep up to 10 hours per night. After a while, the amount of time you sleep will gradually decrease to a normal level. Don't rely on caffeine or energy drinks as a short-term option. They can boost your energy and focus temporarily, but can disrupt your functioning and cause circadian rhythms to be affected even more in the long term.
