Chronic sleep deprivation has serious long-term effects on both physical and mental health. Research links prolonged lack of sleep to increased risks of obesity, heart disease, diabetes, and a weakened immune system. Over time, poor sleep also accelerates cognitive decline, raising the likelihood of memory loss, dementia, and mental health disorders like anxiety and depression. Additionally, sleep deprivation disrupts hormones, leading to higher stress levels and reduced productivity. Prioritizing quality sleep is essential for long-term well-being and disease prevention.
