Sleeping well makes us feel better, more alert, energetic, and better able to concentrate and perform our daily tasks. Getting enough sleep each day is one of the most important things you can do for your health and wellbeing and to reduce your risk for ill-health.
Sleep is an important biological function essential for life. While we sleep many important functions take place that help the body in physical recovery and repair, support brain development, cardiac function and body metabolism, as well as support learning, improving memory and mood.
Without enough sleep we are more likely to have problems with thinking, concentration, memory, reaction times and mood, all of which make it harder to perform our daily tasks and increase the risks of mistakes and accidents.
Regular insufficient or poor sleep contributes to long-term health problems such as obesity, Type 2 diabetes, cardiovascular disease and poor mental health.
