1. Drinking too much water
Drink water when you’re thirsty. Drinking too much water can even cause dehydration. If you are prone to kidney stones, drink at least 2.5 liters of fluid a day. Different factors determine how much water you need, but it’s important not to have too much.

2. Drinking water too quickly
When you drink water too fast, it can create swelling.
3. Drinking the wrong fluids
Not all fluids hydrate you. Some can even dehydrate you.
4. Drinking while eating
This can weaken your ability to digest foods, especially protein, and could lead to GERD or acid reflux. If you drink while eating, don’t overdo it. It may be better to have something to drink 30 minutes before or after a meal.
5. Drinking cold water
Drinking large amounts of very cold water may inhibit the vagus nerve, which is responsible for digestion. This may be more of an issue for those who already have digestive issues.
6. Drinking tap water
There are chemicals and very small plastics in tap water that are not safe for the body. Get a good water filter to filter that out.
