Why This Urologist Wants You To Reconsider Keeping Water By Your Bed

While drinking water later in the evening is not unhealthy in and of itself, waking up in the middle of the night to use the bathroom can interfere with overall sleep quality and well-being.

Lack of quality sleep can affect your immune function, according to integrative immunologist Heather Moday, M.D. While our body is resting, the immune system cells can also focus all efforts and energy on strengthening their immune response, she previously told mbg.

Poor sleep can also affect gut health, which plays a role in cognitive functioning1, immune functioning, and of course, digestion.

Depending on a person's age, health status, and physical or sexual activities, the best time to stop drinking water will vary. In general, though, urologist Vannita Simma-Chiang, M.D., recommends taking your last sip of the day three to four hours before bed. (At least, that's what she does as part of her own pee health routine.) 

And if you really want to ensure you're getting deep and uninterrupted rest, might we suggest taking your last sip of water alongside mbg's sleep support+ supplement?* The formula contains a science-backed trio of ingredients: magnesium bisglycinate (a highly absorbable form of magnesium) to support a steady state of relaxation, jujube to promote calm, and PharmaGABA® to enhance your natural sleep quality.* Even better? It's melatonin-free so you won't wake up feeling groggy the next day.*

While staying hydrated is important, drinking water too close to bedtime might wake you up for much-needed bathroom breaks. In order to stay asleep throughout the night, urologists recommend taking your last gulps of water about three to four hours before bed.
