Horrible idea if you enjoy waking up to pee at 2 AM.
Your kidneys don't shut down at night - they simply continue working on whatever you fill your system with. Drink plenty of water before you sleep and you'll get a full bladder when you wake up, spoiling your rest.
Sleep takes the prize here. Fragmented sleep disrupts everything - hormones, immune system, mood, metabolism. Not even worth it to guzzle water just before sleeping.
Skip fluid intake 2-3 hours before sleeping if you want to sleep undisturbed throughout the night. If thirsty, take a sip or two, but don't down an entire glass.
If you're always thirsty at night, you're dehydrated during the day. Fix it by drinking more water in the morning and early afternoon, not at night.
Exception: You could be ill, hung up, or on meds that dry you out. Then a little might be okay. But still look forward to waking up and urinating.
A few people can drink water late and sleep just fine - lucky bastards with iron bladders. The rest of us aren't so lucky.
Your body may survive for 8 hours without water. It can't survive on chronic sleep disturbance.
Prioritize sleep.
