Staying hydrated is essential for your health, especially during the hot summer months when you’re more likely to lose fluids through sweat. While the common recommendation is to drink "eight glasses of water a day," your hydration needs actually depend on a variety of factors, such as your activity level, climate, and health.
Water accounts for approximately 60% of your body weight and is essential for nearly all bodily functions. It regulates your temperature, aids digestion, supports joint movement, and helps flush waste from your body. Without enough water, you can become dehydrated, which can lead to headaches, dizziness, fatigue, and even more serious health problems.
In this article, we’ll walk you through practical tips to help you stay hydrated all summer long, so you can feel your best and enjoy the sunny days ahead.
How Much Water Should You Drink?
While the "8x8 rule" (eight 8-ounce glasses of water a day) is a helpful guideline for many people, it’s not a one-size-fits-all recommendation. Your hydration needs vary depending on factors like your age, gender, activity level, and the climate where you live.
The U.S. National Academies of Sciences, Engineering, and Medicine suggest the following daily water intake:
- Men: Approximately 3.7 liters (roughly 15 cups) of fluids daily
- Women: Approximately 2.7 liters (roughly 11 cups) of fluids daily
However, this amount should increase if you’re exercising, sweating more than usual, or living in a particularly hot environment. Remember that you also get fluids from foods (like fruits and vegetables) and other drinks, so water isn’t the only source of hydration.
If you’re concerned about your water intake, talk to your doctor, as some medical conditions may require more or less hydration.
10 Tips for Staying Hydrated
- Begin your day with a refreshing glass of water. - Kickstart your morning with a glass of water. It helps wake up your metabolism and gives you an early hydration boost. Just be careful not to drink too much water right before bed, as it may disturb your sleep.
- Carry a Reusable Water Bottle - Carry a water bottle with you all day long. This serves as a reminder to drink more water. Choose a bottle with measurements or motivational phrases to track your progress.
- Set Hydration Reminders - If you have trouble remembering to drink water, set hourly reminders on your phone or smartwatch. Many fitness trackers can notify you when it’s time to hydrate.
- Drink Water Before Meals - Drinking a glass of water before meals helps your body digest food better and can help you feel fuller, which may prevent overeating.
- Infuse Your Water with Flavor - If plain water feels boring, add some natural flavor by infusing it with fruits like lemon, cucumber, or berries. You can also try adding herbs like mint or basil to make it more refreshing.
- Monitor Your Urine Color - Monitor the color of your urine regularly. Clear or light yellow urine usually indicates good hydration, while dark yellow urine might be a sign of dehydration.
- Swap Sugary Drinks for Water - Instead of sugary sodas or juice, try sparkling water or seltzer. These drinks are often more refreshing and help increase your water intake without the added sugar.
- Eat Water-Rich Foods - Numerous fruits and vegetables are rich in water and can help meet your daily hydration requirements. Examples include watermelon, cucumbers, oranges, strawberries, and celery.
- Stay Cool During Peak Sun Hours - Steer clear of direct sunlight between 10 AM and 2 PM, when UV rays are at their most intense. Plan outdoor activities for the morning or evening to prevent excessive sweating and dehydration.
- Hydrate with Electrolytes During Exercise - If you’re engaging in intense physical activity or sweating heavily, drinking water alone might not be enough. Electrolytes such as sodium and potassium assist your body in retaining essential fluids. Consider sports drinks (with low sugar) or electrolyte tablets to replenish lost minerals.
Dehydration Risks in Hot Weather
San Diego’s sunny and dry climate, for example, makes it a popular location for outdoor activities, but the heat can also increase your risk of dehydration. When you're sweating more, your body loses both water and electrolytes. People at higher risk of dehydration include athletes, children, the elderly, and individuals with chronic illnesses.
Dr. Stacie Ly, an internal medicine physician, explains that dehydration can lead to severe health issues, including kidney damage or nervous system problems. To stay safe, drink water consistently, even if you don’t feel thirsty, and keep an eye out for dehydration symptoms, such as dizziness, dry mouth, or dark urine.
Recognizing the Signs of Dehydration
Dehydration can range from mild to severe. Watch for these signs of dehydration:
- Dark yellow or amber-colored urine
- Fatigue or weakness
- Dry mouth or skin
- Dizziness or lightheadedness
- Muscle cramps
- Increased thirst
- Headache
If you experience any of these symptoms, take action right away by drinking water and replenishing electrolytes if necessary.

Proper hydration is essential, particularly during hot weather and increased physical activity. By following these tips and listening to your body, you can maintain healthy hydration levels throughout the summer.
