Sleep is definitely important--not just for the body but also for the mind. Sleeping is as important as eating healthy and exercising. Regular, good quality sleep is important for brain functioning, emotional wellbeing, physical health, daytime performance, and personal safety. When you sleep important physical and mental processes are carried out.
Although not getting enough sleep is common, it poses serious impacts on one's health and wellbeing. Lack of sleep or sleep deprivation increases risk of new and advanced respiratory diseases. It also affects one's ability to think, to remember and to process information. Lack of sleep is also said to trigger anxiety and depression.
Experts say that to stay healthy, adults need seven to nine hours whereas children need nine to eleven, and even more.
