Science and evidence:
National Institute of Neurological Disorders and Stroke details the science of sleep. Getting enough sleep at the right times is essential to our survival. Sleep is important for brain functions and it affects almost every type of system in the body such as – brain, heart, lungs, metabolism, immune function, and mood. Lack of sleep, or poor quality of sleep, increases the risk of high blood pressure, cardiovascular disease, diabetes, obesity and depression.
Several brain structures are involved in sleep – hypothalamus, brain stem, thalamus, pineal gland, the basal forebrain, and amygdala. Sleep has different stages – stage 1, stage 2, stage 3, which are called non rapid eye movement (REM) sleep, and REM stage.
There are two internal biological mechanisms that work together to regulate our sleep and awake cycle. Circadian rhythm controls timing of sleep. It fluctuates with body temperature, metabolism, hormones, and synchronizes with environmental cures such as light and temperature. Sleep-awake homeostasis reminds the body to sleep and it regulates sleep intensity. Factors that affect this homeostasis include medical conditions, medications, stress, sleep environment, food and drink, and exposure to light.
