of their hearts, blood pressure, heart rate and levels of thyroid hormone and the stress hormone cortisol. Sleep supports healthy growth and development. Deep sleep triggers the body to release the hormone that promotes normal growth in teens and children. This hormone also boosts muscle mass and helps repair cells and tissues in children, teens, and adults. Sleep also helps maintain a healthy balance of the hormones that make you feel hungry (ghrelin) or full (leptin). When you don’t get enough sleep, your level of ghrelin goes up and your level of leptin goes down. This makes you feel hungrier than when you’re well-rested.
Thirdly, sleep helps you improve and prepare your daytime performance and safety. Getting enough quality sleep at the right times helps you function well throughout the day. But some people, who lose sleep, can’t control micro sleep, and might not be aware of it. For example, in 2013, The National Highway Traffic Safety Administration estimates that drowsy driving was responsible for 72,000 crashes, 44,000 injuries, and 800 deaths. However, these numbers are underestimated and up to 6,000 fatal crashes each year may be caused by drowsy drivers. As the result,
sleep deficiency is not only harmful on a person level, but it also can cause large-scale damage. For example, sleep deficiency makes you feel lazy to do something, or accidents cause traffic jam then it leads to come late to work. Teens and children, who are sleep deficient are less productive at their work and school. They take longer to finish tasks, have a slower reaction time, decreases creative, and make more mistakes than other children who have enough sleep.
Some people today are so busy in their work, they do not really care about their health, and they don’t get enough sleep at all because they think it isn’t important to have enough sleep. In fact, if you continue to operate without enough sleep, you may see more long-term and serious health problems such as high blood pressure, diabetes, heart attack, heart failure or stroke. But if you care about your health and get enough sleep, you will have a healthy brain function and emotional well-being, have physical health and high longevity, and it helps you improve your daytime performance and safety. That's why sleep is very important!
