2. Harms Your Heart
Getting the correct amount of sleep is very important when it comes to looking after your heart. Sleep plays a vital role in healing and repairing your blood vessels and heart.
Many studies have made a clear link between cardiovascular disease, and those who consistently get below 6 hours of sleep a night – regardless of other lifestyle-related considerations including age, diet and smoking.
Proper rest and sleep are essential for your heart health. Sleep deprivation puts you at a higher risk for cardiovascular disease—regardless of age, weight, smoking and exercise habits.
One study published in 2000 saw a direct link between sleep deprivation and increased resting blood pressure. A later study published in Progressive Cardiovascular Disease suggested that short-term sleep deprivation negatively affects blood pressure, inflammation, and hormones, all contributing to an increased risk of cardiovascular disease.
Another study published in the European Heart Journal, showed that people who sleep less than 6 hours on average, have a greater risk of developing coronary heart disease, and stroke as compared to those sleeping 7 to 8 hours per night.
Some research even suggests that you are twice as likely to have a heart attack or stroke if you sleep on average less than 6 hours a night, compared to those who sleep between 6 and 8 hours a night. Getting too much sleep (9 hours +) consistently, can also be detrimental, and has also been linked to an increased risk of heart disease.
