Sleep is essential to human health. In fact people can survive without food longer than they can without sleep. Getting enough of it allows your body to reset after a tiring day, balances hormones, and eases stress. However, it's not only about the hours you get to sleep. It's also about the quality of your sleep. It's crucial to get quality sleep to avoid health issues such as exhaustion, body pain, weight gain, and chronic diseases, among others.
