Introduction
Have you ever wondered how much water you need every day to stay healthy and energized? While we’ve all heard the “eight glasses a day” advice, the truth is more nuanced. Your body’s hydration needs depend on your activity level, environment, and diet. Let’s dive into what experts say about daily hydration and how to hydrate smarter every day.

Everyone’s Water Needs Are Different

There’s no one-size-fits-all answer when it comes to water intake. Your daily needs are shaped by factors such as:

• Age and body size—Larger or more active bodies need more water.
• Climate—Hotter, humid environments increase water loss through sweat.
• Diet—High-protein or salty foods require extra water for digestion.
• Physical activity—Exercise boosts your body’s need for hydration.
• Men: 3.7 liters (125 ounces)
• Women: 2.7 liters (91 ounces)

Calculating Your Personal Water Needs

To estimate your own ideal water intake:

1. Multiply your body weight (kg) by 35 ml. Example: 60 kg × 35 ml = 2.1 liters per day.

2. Add more if you’re exercising or live in a hot environment.

3. Include hydration-rich foods like fruits and vegetables.

Smart Hydration Habits for Every Day

To hydrate effectively throughout your day:

• Start early: Drink a glass of water upon waking.

• Sip consistently: Small sips throughout the day keep hydration steady.

• Hydrate mindfully: Take a moment to breathe and feel gratitude while drinking.

• Avoid extremes: Both underhydration and overhydration can affect balance.
