To find out when and why it could be wise to do so, we tapped (sorry!) Maddie Pasquariello, MS, RDN, of East Coast Health in Brooklyn, New York.
When to avoid drinking water, according to a dietitian
1. Close to bedtime
If you have nocturia (frequent nighttime awakenings to relieve your bladder), you might be drinking too much leading up to bedtime. Pasquariello suggests spacing your water intake more evenly throughout the day and avoiding water at least an hour before bedtime. Peeing before bed is also a good idea, but frequent awakening to urinate could signal a more serious underlying condition like a UTI or overactive bladder.
2. At night to make up for a lack of hydrating earlier in the day
Drinking a lot of water at once in the evening to compensate for insufficient hydration earlier in the day isn’t ideal. Pasquariello recommends sipping water throughout the day to keep hydrated without straining your kidneys and to avoid bloating or stomach upset. Chugging water is acceptable after intense workouts or on hot days, but limit it to one liter per hour.
3. Shortly before working out
Hydration is crucial before exercise, but avoid drinking too much right before a workout as it can lead to discomfort. Instead, monitor your hydration status before and after exercise and sip water regularly during your workout.
4. When you don’t have immediate access to a bathroom
Avoid drinking large amounts of water during long commutes or when access to a restroom is limited to prevent straining your bladder muscles and pelvic floor. Holding urine every now and then is fine, but don’t make it a habit.
5. To compensate for stress
Stress can lead some people to drink more water, but excessive thirst or unusual urination patterns should be addressed with a doctor. Overdrinking due to stress can cause discomfort and kidney strain.
When to avoid drinking water: The bottom line
While there are times to limit water intake, most people benefit from drinking more water throughout the day. It’s important to be aware of dehydration and overhydration risks but not overly stress about them. Stay hydrated within limits and let your body do its thing!
