The sleep researchers are divided on the question of how much sleep do you actually require. Some say it is 8 hours, others come up with the suggestion of 6 hours. It all depends on the physique and the lifestyle of the person that would determine the length of sleep.
I have seen many people sleeping for over 10 hours yet not getting up well and fresh, [Reasons Why You Wake Up Tired in the Morning]. On the other hand many would just sleep for 5 hours and remain alert and fresh throughout the day. So it is absurd to say that more the sleep hours more healthy and fresh you will feel. Rather the contrary may be true.
Another fact is that it is not only the number of hours that you spend in sleeping rather the quality of sleep would also determine the standard of your fitness and freshness. If you can reduce the period of sleep but improve its quality, the result will be a good health and an early wake-up habit developed over a period of time.
The underlying idea is that your body should get enough sleep time to maintain a good health. You can reduce the sleep time by about one hour without any prejudice to health. In this regards the first step is to improve the quality of sleep for good Health and Sleep.
