Sleep hygiene refers to the quantity and quality of the sleep that you obtain each night. It is important to get an appropriate amount of sleep, making sure it’s not too little or too excessive. Our sleep needs are dynamic and change across different ages and can be impacted by lifestyle and health status. As a general guide, teens need about 8-10 hours a night, young adults and adults need about 7-9 hours, and adults 65+ need about 7-8 hours each night. Having good sleep hygiene is critical to your overall health and can have a significant positive impact on the reduction of high blood pressure, diabetes and other chronic diseases.
