Sleep is very important; while you sleep, your body and brain prepare for the next day. Your brain forms new pathways to help you learn and process information. Sleep is therefore a crucial indicator of overall health and well-being.

The quality of your sleep has a direct impact on your mental and physical health, as well as your productivity, emotional balance, brain and heart health, immune system, creativity and vitality.
