Sleep is one of the most essential human functions. It’s a time where our body and mind switch from ‘doing,’ to recharging and repairing. There are so many factors that can affect our sleep and when sleep is impaired, it can have major consequences on our mental and physical health. Sleep impacts our immune system, respiratory and cardiovascular (heart) systems and our metabolism and ability to manage our weight. The good news is that there are some changes we can make to our diet, lifestyle and night time habits to improve sleep quality.
