Just like food, sleep is an important requirement to the body. Even though it is not an energy source, it assists the body to reenergize and have strength for the following day. Some people think that sleep is somewhat unimportant. Those that think so should know that sleep is more than merely lying on the bed on ones back, it is how one regains the most prized energy. This is why a good night sleep is so important, to an extent that if one lacks a good sleep, it is necessary to use sleep aids. These aids act as the ultimate source to get a great sleep, gain energy and improve one’s health and fitness.
How Sleep is Induced
Sleep is induced by the presence of a naturally occurring substance in the brain known as melatonin. Its production is highest at night, its production acts as a signal to the body that it is time for sleep. People with insomnia naturally have an insufficient production of melatonin. Their bodies will therefore not shift to a restful sleep. Instead, they should opt for the sleep aid medication that can increase melatonin and cause sleep.
