Dr. Chris Winter explains that chronic sleep deprivation erodes cardiovascular health, increases the risk of hypertension, heart attack, stroke, and accelerates cognitive decline and aging. It also has implications for metabolic processes, potentially facilitating weight gain and increasing the risk of conditions like Alzheimer's disease 3.
