Next to water and food, sleep is essential for survival. Ageing, stress and some prescription drugs can all affect sleep. Good sleep is a requirement if we want to support our health and have the energy we need to thrive. Chronic lack of sleep is thought to be linked to diabetes, hypertension, weight gain, memory loss, and the risk of heart disease.
Studies have shown a link between a properly functioning metabolism and getting adequate sleep and rest — lack of sleep can mean lack of weight loss. Night after night of sleeplessness can seriously slow down your metabolism since the body works to conserve energy when it’s fatigued. Make it a priority to get a full night rest every night in order to keep hormone levels in check, including cortisol. High levels of cortisol associated with a lack of sleep are tied to poor mental functioning, weight gain and becoming more resistant to insulin that controls blood sugar.
Although each of us need different amounts to feel our best, the general consensus seems to be about 8 hours per night. This, for many people, is easier said than done and can often be a source of frustration.
