Sleeping Less Than 6 Hours Can Cause Serious Disturbances in the Body — Doctors Explain How
1. Hormonal Imbalance
When you sleep less than 6 hours, stress hormones like cortisol increase. This leads to irritability, fatigue, and constant restlessness throughout the day.
2. Increased Risk to the Heart
Short sleep raises heart rate and blood pressure. Over time, this can increase the risk of heart disease and heart attacks.
3. Reduced Brain Function
Sleeping less gives your brain no time to repair and recharge. This decreases focus, reduces decision-making ability, and increases forgetfulness.
4. Weak Immune System
Lack of sleep weakens the immune response. You become more prone to infections like cold, flu, and viral illnesses.
5. Weight Gain
Short sleep disturbs hunger hormones. You feel hungry more frequently and crave sugary or fried foods, leading to weight gain.
6. Disturbed Blood Sugar Levels
Doctors say that insufficient sleep reduces insulin sensitivity. This directly increases blood sugar levels and raises the risk of diabetes.
7. Negative Impact on Skin
Less sleep slows down collagen production. This makes the face look tired, causes dark circles, and leads to early wrinkles.
8. Hormonal & Metabolic Disturbances
A disturbed body clock slows down metabolism. You feel low energy, sluggishness, and the overall hormonal balance gets disrupted.
