The Urologist’s Core Advice: Front-Load Your Hydration
One of the most consistent recommendations from urologists is this:
👉 Drink most of your water earlier in the day.
What This Means in Practice
- Morning to early afternoon: drink freely
- Late afternoon: moderate intake
- Evening: sip only if needed
- 2–3 hours before bed: avoid large amounts
This allows your kidneys to process excess fluid before bedtime.
Why Drinking Late at Night Causes Problems
Water consumed late in the evening:
- Has no time to be processed
- Moves directly to the bladder
- Triggers nighttime urgency
Even “healthy habits” can backfire if mistimed.
Common culprits:
- Large glasses of water with dinner
- Herbal teas before bed
- Nighttime supplements taken with water
- Drinking out of habit, not thirst
The “Small Sip” Rule Before Bed
Urologists don’t recommend going to bed thirsty.
Instead, they advise:
- Small sips only, not full glasses
- Stop drinking large amounts 2–3 hours before sleep
Dry mouth doesn’t always mean dehydration—it can also be caused by:
- Medications
- Mouth breathing
- Room humidity
A small sip is usually enough.
