Stress is a natural response to pressure, but when it becomes chronic it can damage both body and mind—causing fatigue, irritability, and difficulty concentrating. A new scientific study suggests that chronic stress may be worsened by something as simple as not drinking enough water.
💧 Low Water Intake and Higher Stress Hormones
Researchers at Liverpool John Moores University found that people who drank less than 1.5 liters of fluids per day had a 50% higher cortisol response (the body’s main stress hormone) compared to those who met daily hydration recommendations (about 2 liters for women, 2.5 liters for men).
Professor Neil Walsh, lead researcher, explained:
“An exaggerated cortisol response to stress is linked to a higher risk of heart disease, diabetes, and depression. Keeping a water bottle close—especially before deadlines or presentations—can be a simple, healthy habit.”
🚱 What Happens When the Body is Dehydrated?
-
Increased thirst and dry mouth
-
Reduced sweating and urine output
-
Skin loses elasticity
-
Cells shrink and function less effectively
-
Severe dehydration may cause dizziness, confusion, even organ damage
🥤 How to Prevent and Treat Dehydration
-
Mild dehydration: Drink plenty of water and healthy fluids.
-
Moderate to severe: Oral rehydration solutions (ORS) are recommended, especially for children.
-
Severe cases: IV fluids may be required under medical supervision.
💡 Sports drinks are not always sufficient—they may lack the right balance of electrolytes.
✅ Key Takeaway
Staying well-hydrated doesn’t just keep your body working properly—it can actually lower your stress response and protect your long-term health. So, the next time you’re feeling tense, remember: sometimes the best remedy is simply a glass of water.
