Sleep is crucial state of everyday living that every living creature goes through every 24 hours. We are aware of the impact of poor quality or insufficient quantity of sleep, how it can impair important functions of the brain during wakefulness.

There is also evidence that during sleep, the brain also gets rid of waste material


In the presence of poor quality or insufficient quantity of sleep, these two important functions are impaired and the research community has produced enough evidence that shows that good quality of sleep is essential for daytime functioning. There is also extensive data about the long term consequence on the health of individuals with poor quality sleep.
