It's often recommended that you should stop drinking water two hours before going to bed. This way, you're not flooding your body with extra fluids that may cause an unwanted trip to the bathroom in the middle of the night.
Some research suggests that people with conditions that affect the esophagus, or food pipe, such as achalasia, should avoid drinking cold water.

One of the main reasons to avoid drinking chilled water is because it has a serious implication on your digestion. Chilled water as well as some cold beverages contract the blood vessels and also restrict digestion. The natural process of absorbing nutrients during digestion is hindered when you consume chilled water.
The risks and disadvantages of drinking cold water include thickening of mucus causing respiratory difficulty, headaches, tooth sensitivity, slowing gastric emptying, aggravating achalasia (a rare disease making it difficult for food to pass from the esophagus to the stomach), and causing 'cold stress'.
