Proper hydration is key to boosting mood, supporting weight management, and improving focus. Knowing when and how much water to drink can help you maximize these benefits and maintain your overall well-being.

Understanding the Importance of Hydration

Water is essential for nearly every bodily function. “Every cell in our body requires water to function optimally,” says Sarah Krieger, registered dietitian nutritionist based in Florida. Hydration supports digestion, heart health, brain function, and more. But drinking the right amount isn’t enough; timing plays a crucial role in how your body benefits from water.

The general guideline for daily fluid intake varies depending on age, sex, activity level, and environment. Krieger advises clients to drink half their body weight in ounces. For example, a person weighing 140 pounds should aim for 70 ounces of fluids daily. The National Academies of Sciences, Engineering, and Medicine recommend approximately 13 cups (104 ounces) for men and 9 cups (72 ounces) for women.

When to Drink Water: 7 Optimal Times

1. Right After Waking Up: Hydrate to Kickstart Your Day

Starting your morning with 1 to 2 cups of water helps replenish fluids lost overnight. Because you don’t drink while sleeping, your body can wake up dehydrated, which can leave you feeling sluggish. Drinking water first thing boosts metabolism and helps with digestion, especially if you take morning medications.

Pro tip: Coffee can count toward hydration in moderation but shouldn’t replace water.

2. Before Meals: Curb Your Appetite and Support Weight Management

Drinking a glass of water before eating can promote satiety and reduce overall calorie intake, aiding weight control. A 2018 study found that individuals who drank water prior to meals consumed fewer calories and felt equally satisfied as those who didn’t.

Drinking cold water might even help curb appetite further. A 2019 study showed that participants who drank iced water ate less than those who drank warm water.

3. During Meals: Aid Digestion, Especially with Fiber-Rich Foods

Water helps your digestive system process food effectively, especially fiber-rich fruits, vegetables, and whole grains. Fiber absorbs water to form stools and promote regular bowel movements, reducing the risk of constipation and maintaining gut health.

4. In the Midafternoon: Combat Energy Slumps Without Caffeine

Instead of reaching for sugary snacks or coffee during the common afternoon energy dip, try drinking water to stay energized and focused. Dehydration can cause fatigue, irritability, and mood swings. Staying hydrated supports mental clarity and steady energy levels throughout the day.

5. When You Have a Headache: Relieve Symptoms by Rehydrating

Dehydration is a common cause of headaches and migraines. According to the National Headache Foundation, increasing water intake can reduce the frequency and severity of migraines. If you feel a headache coming on, drinking water should be your first remedy.

6. Before, During, and After Exercise: Optimize Performance and Recovery

Hydrating before physical activity is essential but avoid drinking large amounts immediately prior to exercise to prevent discomfort. Instead, increase fluid intake in the days leading up to intense workouts.

During moderate exercise, drink water regularly to replace fluids lost through sweat. Post-workout hydration aids recovery by replenishing lost fluids and maintaining electrolyte balance.

7. Before Bedtime: Keep Water Nearby but Avoid Excess

While it’s important to stay hydrated before sleep, drinking too much water can interrupt rest due to nighttime bathroom trips. Keep a glass nearby to sip if you wake thirsty, which is especially helpful for those on medications that cause dry mouth.

Expert Tips to Build a Sustainable Water-Drinking Habit

Track Intake With Bottles or Apps

Counting cups or ounces can be confusing. Try measuring how many times you fill your water bottle (e.g., a 500 ml bottle filled four times equals two liters). Apps like Plant Nanny or Madefor can gamify hydration and keep you motivated.

Customize Your Water

If plain water feels boring, experiment with temperature, carbonation, or infusions such as lemon, cucumber, or mint. These options can make drinking water more enjoyable.

Keep Water Visible

Place a water bottle or glass within reach throughout the day and by your bedside as a visual reminder to drink regularly.
