If your goal is to remain fit and healthy, there are a number of things that need to be done right in addition to a healthy diet, strength training and aerobic exercise. One of them is sleep: the right amount and the right time. Not getting the right amount of sleep affects all your daily activities. If you had not slept well the last night, it would be difficult for you to get up in the morning for your exercise and neither will you be in the right mood to follow a proper diet plan. And, these are just two of the many issues one can face not getting enough sleep.
