Good quality sleep is a necessity for every living object. We need to make sure we are having a sufficient, complete and quality sleep. According to some studies, the quality of sleep is related to risk of having heart disease and stroke.
If a person is used to not having a complete at least 8 hours of sleep, he is more prone to having high blood pressure. Metabolic Syndrome or having high blood pressure, high cholesterol, diabetes and being overweight are results of constant less than 6 hours of sleep every day. Sleep deprivation lowers metabolism and trouble losing weight that increases the risk of having heart disease.
Sleep apnea is a sleeping disorder that causes pauses or stops in breathing while sleeping is a common cause of heart problems among the sleep disorders. More than 50% of people with sleep apnea develops heart disease and stroke.
Another sleep deprivation disorder called shift work; a circadian rhythm disorder is also linked. People who are working on changing shifts, night shifts and not regular working times have an increased risk of cardiovascular disease. We generally don’t know how many people have circadian disorders but about 15-20% of the U.S. workforce are shift workers.
The most basic to explain is when the tissue in the back of your throat relaxes and blocks your airway while you sleep. You stop breathing, so your brain signals your throat muscles to contract, which opens up your airway again. This can happen dozens or even hundreds of times a night. Your brain also releases stress hormones during these episodes. They can raise your heart rate and your blood pressure -- which raises your chance of developing heart failure or making it worse.
There is much more research that shows direct connections between sleep quality and development of heart disease but sleep is a vital part of sustaining our life so make sure you practice to have the best quality.
