Knowing for sure how many hours of sleep adults need is a point of contention. While some may feel energized on six hours of sleep, it might take others nine hours to feel awake. In our busy, hustle, go-go society it may seem from the outside that you can feel your best in just a few hours. But this is highly unlikely and pretty dangerous for your health and performance.
Before you start to compare against what your friends are saying or what a top CEO is suggesting, you should look at your own needs first. You need to look at sleep in a holistic way. It’s just as important to balance sleep as it is healthy foods and regular exercise.
There are research based recommended hours for different age groups as a good starting point. But this should also be paired with evaluating other factors such as your work schedule, lifestyle and medical needs.
