According to Sheldon G. Sheps, M.D, for the Mayo Clinic, less than 6 hours of sleep ups our risk to have high blood pressure because the body can’t regulate the production of stress hormones when we lack sleep.
So, if your sleepless nights were the result of stress in the first place, your body can translate all of this into a physical problem like hypertension, which is bad news! A high blood pressure can lead to strokes, heart attack, and kidney disease. Plus, it can cause erectile dysfunction in men and lower libido in women.
According to the Foundation for Traffic Safety, drivers who had five to six hours sleep per night are more likely to get into a car accident compared to drivers who sleep for more than seven hours. Technically and physiologically, if you are sleep deprived, then your level of impairment is comparable to someone who is drunk.
Furthermore, and according to another research from 2017, when your eyes are tired and blurry, they delay communication between neurons in the brain, which dangerously affect the decision-making while driving.
