Staying hydrated is one of the easiest health practices, yet misconceptions about hydration persist and mislead many. From the idea of needing '8 glasses a day' to the belief that only plain water counts, misinformation can lead to both dehydration and unnecessary overhydration. Here's a straightforward, science-based guide to what your body really requires.
Myth 1: Everyone should drink 8-10 glasses every day.
Fact: Hydration requirements differ significantly depending on factors like climate, diet, activity levels, and body weight. Most adults need around 2-2.5 liters daily, but those in warmer areas like Pune or those who exercise regularly may require more. The best gauge is your thirst and the color of your urine (pale yellow is optimal).
Myth 2: Only plain water can hydrate you.
Fact: Hydration can also be obtained from fruits, vegetables, coconut water, soups, herbal teas, and milk. Foods high in water content, such as cucumbers, oranges, melons, and tomatoes, play a significant role in your daily fluid intake.
Myth 3: If you feel thirsty, you're already dehydrated.
Fact: Thirst is a natural early signal -- not a warning sign. Mild dehydration is common and can be easily remedied by drinking water consistently throughout the day. However, persistent fatigue, dizziness, dry mouth, or dark urine may suggest more serious dehydration.
Myth 4: More water equals better health.
Fact: Drinking too much water can lead to hyponatremia, a dangerous drop in sodium levels. This often occurs during intense workouts when individuals consume excessive plain water without electrolytes. Balance is essential -- water, salts, and minerals must be maintained in the right proportions.
Myth 5: Cold water is harmful to digestion.
Fact: There is no substantial scientific evidence to back this claim. Cold water is safe to consume and can actually aid in cooling the body during hot weather or after physical activity. The temperature of your water is a matter of personal preference.
Drink steadily through the day instead of chugging at night.
Have electrolytes during long workouts or outdoor activities.
Eat water-rich fruits daily.
Reduce caffeinated and high-sugar drinks that cause dehydration.
