Quality of sleep

Studies have found a relationship between the quantity and quality of one's sleep and many health problems. 

• Insufficient sleep affects growth hormone secretion that is linked to obesity; 
• Blood pressure usually falls during the sleep cycle, however, interrupted sleep can adversely affect this normal decline, leading to hypertension and cardiovascular problems. 
• Insufficient sleep impairs the body's ability to use insulin, which can lead to the onset of diabetes.
