More News : While 7 to 8 hours of sleep is considered healthy for adults, oversleeping for 10–12 hours or more may negatively affect overall health. According to health experts, excessive sleep can slow down brain function, leading to fatigue, poor concentration, and reduced cognitive performance.
Research suggests that prolonged sleep may also weaken memory, reduce mental alertness, and increase the risk of anxiety and depression. Studies have further linked oversleeping to heart-related issues, including a higher risk of heart disease, stroke, and heart attacks.
The risks are greater when long sleep is combined with low physical activity or a sedentary lifestyle. Oversleeping can slow metabolism, contribute to weight gain, and increase the risk of obesity. It may also raise insulin resistance, which is associated with type-2 diabetes. Additionally, excessive sleep disrupts the body’s natural circadian rhythm, causing fatigue, irritability, and daytime drowsiness.
If someone regularly sleeps 10–12 hours or more but still feels tired, it could be a sign of underlying health conditions such as sleep apnea, depression, or thyroid disorders. Experts recommend maintaining a consistent sleep schedule and limiting sleep to 7–8 hours for better physical and mental health.
