When you don’t get enough sleep, your body and mind pay the price. Sleep deprivation weakens your immunity, making you more likely to fall sick. It affects your memory, concentration, and decision-making, which can impact your daily life and work. Lack of sleep also increases stress hormones, leading to mood swings, irritability, and anxiety. Over time, it raises the risk of serious health problems like high blood pressure, diabetes, heart disease, and even weight gain. Getting 7–8 hours of good-quality sleep isn’t a luxury; it’s a necessity for a healthy life.
