Accounting for up to 75% of your body weight, water plays a key role in regulating everything from brain function to physical performance to digestion and much more. Still, while it’s clear that drinking enough water is important to health, you may wonder whether timing matters.

1. If you drink an excessive amount of water before going to bed, you may find that you have to get up multiple times throughout the night to use the restroom.This can be disruptive to your sleep and leave you feeling tired the following day.

2. After eating fruits: Because some fruits contain a high concentration of acid, drinking water immediately after eating these fruits can cause an increase in the acidity level in your stomach, which can lead to heartburn and other uncomfortable symptoms.

3. While you are eating: Drinking water while you are eating can dilute the digestive juices that are already present in your stomach, which can make digestion more difficult for your body.
