Why should you drink water in the morning?
According to Harvard Health Publishing, after 7-8 hours of sleep, the body loses water slightly even though it does not sweat much. Drinking a glass of water right after waking up helps:
Activate the digestive system, support early bowel movements.
Improve blood circulation, as water thins the viscosity of the blood after a long sleep.
Increase alertness, as mild dehydration can cause fatigue and decreased concentration.
Many studies cited by Harvard also show that drinking water in the morning helps stabilize blood pressure and supports body temperature regulation.
Is drinking water at night beneficial or harmful?
Cleveland Clinic believes that drinking a glass of water about 1-2 hours before bed has three main benefits:
Reduces the risk of night cramps, especially in older adults.
Helps the kidneys eliminate toxins from the blood.
Helps the body maintain moisture, limit dry mouth and dry skin at night.
However, the Mayo Clinic warns against drinking too much water too close to bedtime, as it can cause drowsiness, affecting sleep quality. The appropriate amount is 100-200 ml, depending on your health condition.

Morning: drink 1 glass of water (200-250 ml), warm water if the stomach is sensitive.
In the evening: drink 100-200 ml 1-2 hours before bed.
Limit sugary or caffeinated drinks at this time.
People with heart and kidney disease should consult a doctor before increasing their water intake in the evening.
Conclusion
