The relationship between sleep and our health
Most of us don’t realise that sleep has a strong relationship to our health. Long term health consequence like higher risk of diabetes type 2, high blood pressure and heart disease are all associated with lack of sleep. Equally alarming are the brain consequences of sleep disturbance or lack of sleep on a regular basis.
Science has shown us that sleep not only allows our bodies to rest and repair, but new evidence shows sleep is required to flush toxins from the brain.
Insufficient sleep is also associated with weight gain. During sleep our bodies’ secrete hormones that help control appetite and regulate metabolism, too little sleep upsets the balance of these hormones and leads to increased cortisol levels, our ‘stress hormone’, and insulin secretion following a meal. High levels of insulin are associated with weight gain and are a risk factor for type 2 diabetes.
