Getting enough sleep is essential for helping a person maintain optimal health and well-being
Sleep is an important part of our daily routine. Quality sleep and getting enough of it at the right times is as essential to survival as food and water. Getting enough sleep is essential for helping a person maintain optimal health and well-being. When it comes to health, sleep is as vital as regular exercise and eating a balanced diet.
Everyone needs sleep, but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body – from the brain, heart, and lungs to metabolism, immune function, mood, and disease resistance. Research shows that a chronic lack of sleep, or getting poor quality sleep, increases the risk of disorders including high blood pressure, cardiovascular disease, diabetes, depression, and obesity.
Better productivity and concentration
Sleep has links to several brain functions, including: concentration, productivity, cognition. A more recent 2015 study in the Journal of Child Psychology and Psychiatry showed that children’s sleep patterns can have a direct impact on their behavior and academic performance.
Better calorie regulation
There is evidence to suggest that getting a good night’s sleep can help a person consume fewer calories during the day. One study in the Proceedings of the National Academy of Sciences of the United States of America says that sleep patterns affect the hormones responsible for appetite. When a person does not sleep long enough, it can interfere with their body’s ability to regulate food intake correctly.
Greater athletic performance
According to the National Sleep Foundation, adequate sleep for adults is between 7 and 9 hours a night, and athletes may benefit from as many as 10 hours. Accordingly, sleep is as important to athletes as consuming enough calories and nutrients. One of the reasons for this requirement is that the body heals during sleep. Other benefits include: better performance intensity, more energy, better coordination, faster speed and better mental functioning.
Lower risk of heart diseases
One risk factor for heart disease is high blood pressure. According to the Centers for Disease Control and Prevention (CDC), getting adequate rest each night allows the body’s blood pressure to regulate itself. Doing so can reduce the chances of sleep-related conditions such as apnea and promote better overall heart health.
There is a link between getting adequate sleep and reducing inflammation in the body. A study in the World Journal of Gastroenterology suggests a link between sleep deprivation and inflammatory bowel diseases that affect people’s gastrointestinal tract. The study showed that sleep deprivation can contribute to these diseases — and that these diseases, in turn, can contribute to sleep deprivation.
Stronger immune system
Sleep helps the body repair, regenerate, and recover. The immune system is no exception to this relationship. Some researches suggest that better sleep quality can help the body fight off infection.
Sleep is thus a vital, often neglected, component of every person’s overall health and well-being. Sleep is important because it enables the body to repair and be fit and ready for another day. Getting adequate rest may also help prevent excess weight gain, heart disease, and increased illness duration.
