It is widely known that sleep is vital to our health, happiness, and cognitive abilities. It is undeniable that by sleeping you are contributing to maintaining your physical and mental health at sustainable levels. When sleeping, your body is able to grow and repair itself, and your brain is able to process and remember memories; this is done to help you prepare for the day ahead. Furthermore, the amount of sleep you get also affects your cardiovascular system, immune system, and metabolism (2). When you enter non-REM (non-rapid eye movement) sleep, your blood pressure and heart rate fall. Your parasympathetic system (which is the sector of your nervous system that keeps your body in a “rest and digest”(3) state) takes over control of your body and allows your heart to relax; this contributes to maintaining a healthy cardiovascular system. Regular sleep also allows you to avoid health problems such as coronary heart disease, high blood pressure, and strokes. Furthermore, sleep also allows your immune system to work and, therefore, combat infections. Your metabolism also benefits if you get the correct amount of sleep. For example, a proper and stable circadian clock ensures that your liver is able to digest fats at suitable times. Sleeping for an appropriate amount of time also helps you avoid an increased risk of developing health issues such as a diminished ability to respond to insulin, obesity, and metabolic syndrome (4) (which is a grouping of conditions that can increase susceptibility to diseases like coronary heart disease, diabetes, and stroke(5)). Despite such insights, we are still left with the question, “How long should we sleep to be able to profit off of these benefits?” unanswered.
