The Lowdown on H2O: Personalizing Your Water Intake
Amount of hydration required daily
So you've heard the golden rule for water intake: eight 8-ounce glasses a day, huh? Well, buckle up, 'cause in reality, it's a more individualized game. The Institute of Medicine (IOM) has some different recommendations based on factors like your sex, age, and if you're pregnant or breastfeeding.
Water Recommendations: Tailored to You
The old 'eight glasses' rule isn't backed by solid research, and that body of water you're made up of? It's comprised of 60% H2O. Every system in your body dang near requires it to function properly. Your recommended intake factors in your sex, age, activity level, and other factors, like whether you're pregnant or breastfeeding.
Adults of Age
Demographic
The IOM recommends that men 19 and up should aim for around 3.7 liters, or 13 cups, daily. For women, it's 2.7 liters, or 9 cups. This includes all the fluids you consume, not just the liquid type.

Special Considerations
7-8 cups, or 56-64 total ounces
You may need to throw in extra water if you're living in a scorching climate, working out like a champ, or going through some nasties, like diarrhea or vomiting.
- If you work out hardcore, add an additional 1.5-2.5 cups of water each day.
- Hot climate dwellers may need extra, too.
- If you live high up, you may need more water as well.
- When you endure a fever, vomiting, or diarrhea, your body loses more fluids than usual, so drink up! Your doctor might even suggest opting for drinks with electrolytes to maintain a stable electrolyte balance.

Dehydration
Dehydration, when your body loses more water than it takes in, can lead to symptoms ranging from extreme thirst to fatigue. You may notice less frequent urination or darker urine, especially in children. Dehydration can lead to confusion, mood changes, overheating, constipation, and the formation of kidney stones. Severe dehydration may require hospital treatment, including intravenous fluids and salts.

On the flip side, drinking too much water can dilute the electrolytes in your blood, leading to hyponatremia. Symptoms include confusion, headache, fatigue, nausea or vomiting, irritability, muscle spasms, weakness, seizures, and coma. This condition is more common in people with a smaller build and children.

Here are some tips to help you drink enough water:
- Carry a water bottle with you at all times.
- Don't limit yourself to plain water. Milk, pure fruit juices, teas, and broth also count toward your fluid intake.
- Steer clear of sugary drinks, as they're high in calories.
- Drink a glass of water when you dine out instead of ordering another beverage. You'll save some cash and cut some calories.
- Add a twist of lemon or lime to your water.
- If you're exercising heavily, consider opting for a sports drink with electrolytes to help replenish those you lose through sweating.
