Introduction
Water is essential for life, and staying hydrated throughout the day is crucial for maintaining overall health. But one common question many people ask is:
“Is drinking water before sleep good or bad?”
Some believe it helps detox the body, while others worry about sleep disturbance due to frequent bathroom trips.
In this detailed guide, we will explore the benefits, risks, myths, and best practices of drinking water before bedtime, so you can make the right decision for your health.

This makes hydration important — but timing and quantity matter a lot.
