The findings suggest that individuals who sleep less than six hours may be at increased risk of atherosclerosis, a cardiovascular disease caused by a buildup of plaque in the arteries. The study recommends adults get seven to eight hours of high-quality sleep, finding that those who slept longer – along with those who slept poorly – may also increase their risk for the disease. Sleep quality is defined as the duration of time asleep and the frequency of movement while asleep. Good sleep quality is described as sleeping through the night with minimal waking.
Delayed reactions, trouble remembering and an inability to focus can all be symptoms of high levels of adenosine, which builds up in the brain after too little sleep. Unwanted pounds could also be a side effect of insufficient rest as leptin, the hormone that suppresses hunger, decreases without sufficient sleep, and levels of ghrelin, the hunger hormone, increase.
