Not getting enough sleep not only makes you ugly, but also makes you fatter
A poor night's sleep or no sleep won't kill you, but chronic sleep deprivation can have unintended consequences and increase the likelihood of accidents. Just by thinking about it, you know what will happen if you don’t sleep: you will look haggard, moody, depressed, and not interested in anything else in life; it will also encourage you to eat and drink too much, drink too much caffeine, yell at the people around you, and it will also make you avoid exercise and sex (don’t doubt it) because you are too tired!
In addition, medical research has found that poor sleep habits can have the following side effects: excessive stress, confusion, memory loss, lack of ability to learn new things, weight gain, diabetes, cardiovascular disease and depression.
How did this happen? The first thing to understand is that sleep controls most of our happiness and well-being through our biological clock. The stress hormone "cortisone" should peak in the morning, decrease gradually as the day goes by, and should reach its lowest level after ten o'clock in the evening, when the secretion of "melatonin" is highest. It is this hormone that tells you it's time to sleep.
Once released, melatonin slows down body functions and lowers blood pressure, which in turn lowers core body temperature so you're ready for sleep. High concentrations of melatonin promote more deep sleep and help maintain healthy levels of growth hormone, thyroid hormone, and sex hormones in men and women. If you have trouble winding down at night because of stress, you may be producing too much cortisone to fight the sleep-inducing hormone melatonin.
Many sleep-related hormones, such as growth hormone, must be released during sleep.
When you enter deep sleep, the pituitary gland releases a large amount of growth hormone. This is the time of day when the secretion is greatest. Growth hormone not only stimulates growth and cell regeneration, but also invigorates cells, restores skin elasticity, and strengthens the movement of amino acids across cell membranes. What's even better is that it allows cells to use "fat" as energy to help you maintain weight. Without proper sleep, growth hormone will be locked in the pituitary gland, negatively affecting your fat-to-muscle ratio. In the long run, you will have high fat mass and low lean muscle mass, making you a veritable puffer!
