The amount of water a person should drink each day can vary depending on age, body size, activity level, climate, and overall health.

A common guideline is the “8×8 rule” — about eight 8‑ounce glasses of water a day (around 2 liters or half a gallon). However, many health experts, including the U.S. National Academies of Sciences, Engineering, and Medicine, suggest a more detailed approach:

– Men: About 3.7 liters (125 ounces) of fluids per day

– Women: About 2.7 liters (91 ounces) of fluids per day

This includes not only plain water but also fluids from beverages (like tea, coffee, milk) and moisture in foods (like fruits and vegetables).

Tips to know if you’re getting enough water:

– Your urine is pale yellow (dark urine can signal dehydration).

– You rarely feel thirsty.

– You have steady energy and normal digestion.

Situations where you may need more water:

– Hot or humid environments.

– Intense physical activity or exercise.

– Fever, vomiting, or diarrhea.

– Pregnancy or breastfeeding.

⚠️ Note: Drinking *too much* water in a short time can cause water intoxication (hyponatremia), though this is rare.
