Many of us may keep a glass of water by our bed, but you don’t want to drink too much water during the night. While some water will keep us from being dehydrated and can improve our mood, too much can lead to frequent bathroom trips.
In some cases, drinking too much water can cause nocturia (urinating several times throughout the night) which disrupts the sleep cycle. It makes you more prone to falls, increases your chances of depression, and lowers focus and productivity.
As a general rule of thumb, try to stop drinking water 3 to 4 hours before bed, suggests urologist Vannita Simma-Chiang. However, "Any time you feel thirsty or your throat is dry, it's a good idea to drink water," Simma-Chiang concedes.
