Drinking Water Before Bed Can Disrupt Your Sleep
Drinking too much water before bed can make you wake up to use the bathroom.
This is called nocturia.
Waking up repeatedly can interrupt the deepest parts of sleep.
Poor sleep may leave you tired and unfocused the next day.
However, going to bed very thirsty can also be uncomfortable.
Dehydration may cause a dry mouth or leg cramps at night.
A few small sips can help if you are especially thirsty.
Try to drink most of your water earlier in the day and avoid large amounts during the two hours before bedtime.
Large amounts of water before bed can cause nocturia, or repeated nighttime urination.
Nighttime bathroom trips may interrupt deep, restorative sleep and cause daytime fatigue.
Going to bed dehydrated may contribute to dry mouth and nocturnal leg cramps.
A few sips before sleep may help address thirst and replace some overnight fluid loss.
Health experts generally recommend avoiding large amounts of water during the two hours before bed.
