How much water should you be drinking?

Water is more than hydration — it’s life support. It fuels your brain, regulates your temperature, cushions your joints, flushes toxins, and energizes your cells. Yet most people don’t drink enough. So how much should you be drinking?

Why there’s no single answer

Your recommended water intake depends on a range of personal factors:

• Body weight
• Activity level
• Climate and environment
• Age and sex
• Medications or health conditions
• Diet — especially if you consume caffeine or alcohol, which are diuretics

While the popular “8 glasses a day” (64 oz) is a decent baseline, newer science suggests personalized hydration based on body weight is more effective.

A simple starting point

One widely accepted formula is to drink half your body weight in ounces per day.

Recommended intake by body weight

The chart below gives a quick reference for daily water targets based on body weight. These are estimates — your actual needs may vary.

What about athletes and active people?

If you exercise regularly or sweat heavily, your hydration needs go up significantly. The American Council on Exercise recommends:

Our recommendation

While individual needs vary, we recommend drinking at least 60 oz of water per day as a starting point — and often more depending on your lifestyle and body size. Consistent hydration improves energy, focus, recovery, and long-term health in ways that are hard to notice until you start tracking.

Know your body. Talk to your doctor.

Hydration is personal. Your body is unique. Always consult with your physician before making significant changes to your water intake, especially if you have heart, kidney, or metabolic conditions. Sponge Hydration is here to help — not replace medical advice.
