A Good Night's Sleep May Decrease Risk of Cardiovascular Disease
For adults, a good night’s sleep is considered to be seven to eight hours of sleep per night. Short sleep, which is defined as less than 7 hours of sleep a night, leads to poor judgment and memory, difficulty making decisions, lack of focus and attention and an increased risk of illness including high blood pressure or hypertension, coronary heart disease, stroke, diabetes, and obesity. The increased risk of these diseases is real, which is why sleeping for a minimum of 7 hours a night is important.
Sleep allows the body to rest and slow down, which results in a number of physiological responses that include lower blood pressure, heart rate, respiratory rate, and changes in hormone levels that regulate stress, the immune system, and our appetite. All of these factors contribute to our psychological and physiological health—in other words, our mood, how we feel, and how we function. To be at our best, and reduce our risk of disease, especially heart disease, good sleep is important.
