Sleeping is an important role in every living beings.Sleep is an essential function that allows your body and mind to recharge, leaving you refreshed and alert when you wake up. Healthy sleep also helps the body remain healthy and stave off diseases. Without enough sleep, the brain cannot function properly. Most adults require between seven and nine hours of nightly sleep. Children and teenagers need substantially more sleep, particularly if they are younger than five years of age.
An internal body clock 4 regulates your sleep cycle, controlling when you feel tired and ready for bed or refreshed and alert. This clock operates on a 24-hour cycle known as the circadian rhythm. After waking up from sleep, you’ll become increasingly tired throughout the day. These feelings will peak in the evening leading up to bedtime. As natural light disappears in the evening, the body will release melatonin, a hormone that induces drowsiness. When the sun rises in the morning, the body will release the hormone known as cortisol that promotes energy and alertness. Yet millions of people do not get enough sleep and many suffer from lack of sleep.
While you’re asleep, your body is taking the time to rest, recover, and rebuild so it can perform at its peak the next day. By healing damaged cells, boosting your immune system, and recharging your cardiovascular system, your body gets the reboot it needs to wake up feeling revived and alert for your daily activities.When you forget to count those sheep each night, your circadian rhythms get out of sync and begin to harm your hormone levels. Hormones regulate everything from your menstrual cycle to your hunger levels. When your body doesn’t get enough sleep, its ability to know when it’s satisfied can become impaired. The hormones responsible for making you feel full or hungry (leptin and ghrelin, respectively) can fall out of sync when you’re tired and cause you to feel hungrier than you should.
The loss of sleep can affect the function of a region of the brain known as the hypothalamus, which regulates appetite and the release of energy.When the body is well-rested, your hormones remain balanced and your appetite is naturally controlled. With that, your temptation for unhealthy foods tends to go away as well.
