How much sleep do you need?
The day starts the right way after a good night's sleep. And there are some pretty good reasons to make sure you get a good night’s sleep.

A good sleep can lift your concentration, mood, and could reduce your risk of heart disease, high blood pressure and diabetes.^ There’s also the sobering fact that sleep deprivation was linked to more than 3,000 deaths in 2016–17, almost 400 of those from vehicle or industrial accidents, according to the Sleep Health Foundation.*
Poor sleep impacts your mental health and leads to worse decisions as the following image shows.
