It helps our brain to function and affects many different systems within our body from our emotional state to our physical state.

Sadness and depression are also linked to reduced sleep and inadvertently could contribute to suicide attempts or taking inappropriate risks. Emotion can affect us in work or activities and can affect the decision-making process, so having enough sleep helps in the control of our emotions at the correct times. Happiness is crucial to living a healthy and fulfilled life and this can be affected by poor sleep as well as social interaction, which can be adversely affected.
