How Much Water Should I Drink Every Day for Optimal Health?

Water is essential for life—it’s what keeps us healthy. But how much should you be drinking every day, to stay healthy? The answer might surprise you. Let’s take a look at the science behind daily water intake and the health benefits it has.


Many adults need around one and a half cups of water per day, which is equivalent to drinking eleven 8-ounce glasses. That number may vary depending on your activity level, climate, and other factors such as age and pregnancy status. For example, if you work out often or live in a hot climate, you may need to drink more than one and a half cups each day to stay hydrated.


Drinking water is an important part of staying healthy. Our bodies are mostly composed of water, so when we become dehydrated we can start to experience physical symptoms such as headaches and fatigue. Drinking the right amount of water also helps to flush toxins from our bodies and keep our skin looking healthy and hydrated.

Drinking enough water can help with mental clarity and focus as well as improve our moods by providing essential nutrients needed for proper brain function. Studies have also shown that people who drink enough water throughout the day tend to have better eating habits than those who don’t drink enough water- likely because they’re not confusing thirst with hunger signals!


Drinking enough water every day is essential for optimal health and wellbeing. While the exact amount of water needed may vary, on average, the recommendation is 11 8-ounce glasses a day for adults. So make sure you’re getting your daily dose of H2O!
