The general guideline is 35ml per kg of bodyweight per day. For a 70kg person this is approximately 2,450ml (about 10 cups). This increases with activity, heat, and certain health conditions. The old "8 glasses a day" rule is a rough approximation — individual needs vary significantly.

Yes — despite popular belief, caffeinated beverages like coffee and tea do count towards your daily fluid intake. While caffeine has a mild diuretic effect, the net fluid contribution is still positive. Water, herbal tea, and milk are the ideal hydration sources, but all beverages count.

Early signs: dark yellow urine, feeling thirsty, dry mouth, fatigue, and headaches. Severe dehydration causes dizziness, rapid heartbeat, and confusion. The simplest daily check: aim for pale yellow urine (straw-coloured). Clear urine may indicate over-hydration; dark amber means drink more water now.
