Sleep is a biological necessity! Having a good night's sleep is essential for health. As per doctors, six hours of sleep every night is necessary for a person. Depending upon your age and activity level, the amount of sleep you need will vary. Still, too much of sleep can be actually called a medical disorder as it has been linked to many medical problems. Similarly, being a night owl and sleeping for less than six hours will also affect your health. It can make you feel drowsy for the whole day, and can even shorten your life expectancy. So it's very clear that a solid night's sleep is essential for long and healthy life.
As per a new study, it has been found that men who sleep less than six hours a night can face an increased risk of cardiovascular disease compared to those who sleep between seven and eight hours.
The study showed that poor quality sleep of less than six hours increases the risk of atherosclerosis by 27 percent compared to seven to eight hours of sleep.
Atherosclerosis refers to the build-up of fats, cholesterol and other substances in and on the artery walls throughout the body. Similarly, women who slept more than eight hours a night had an increased risk of atherosclerosis.
Jose M Ordovas, a researcher at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) in Madrid, said the following points:
Six hours of sleep every night is necessary for a person!
- "Cardiovascular disease is a major global problem and we are preventing and treating it using several approaches, including pharmaceuticals, physical activity and diet."
- "We have to include sleep as one of the weapons we use to fight heart disease -- a factor we are compromising every day."
- "Many people think alcohol is a good inducer of sleep, but there's a rebound effect. If you drink alcohol, you may wake up after a short period of sleep and have a hard time getting back to sleep. And if you do get back to sleep, it's often a poor-quality sleep."
Lack of sleep has been known to raise the risk of cardiovascular disease by increasing heart disease risk factors such as glucose levels, blood pressure, inflammation and obesity.
