Crazy, right? How can water, a liquid crucial in our diet, be so harmful to sleep? Let’s break down the facts. Water is essential for hydration of the body. It helps regulate our body temperature, assists in proper circulation, and speeds up metabolism among many things. The human body is made up of 50 to 75 percent water. And we lose water quite easily when we urinate, sweat, or even so much as exhale. An adult can lose up to 3 liters of water in a day and the elderly lose about 2 liters of water per day. Drinking water constantly makes up for these losses and prevents dehydration, allowing our bodies to function optimally. Men and women are advised to drink 2.6 liters and 2.1 liters of water respectively. Drink too much water before bedtime however, and you will curse yourself for the night to make several trips to the bathroom. It is true that digestion slows down at night when you’re asleep. But it sure doesn’t stop. Binging on water or any other liquid before sleeping will cause your bladder to fill up and prompt you to wake up. As a result, your sleep will be interrupted occasionally, and you will have brief periods of sleep. This won’t be enough for rest and recovery. Even worse, you may not be able to asleep again after a trip to the bathroom! Besides getting puffy eyes, you will have problems staying awake during daytime. Taking a nap in the afternoon to make up for lost hours of sleep will only make it worse for you. Your sleeping pattern will become imbalanced and you will eventually develop insomnia. You can avoid all this by simply limiting your water intake at night. Or, you can keep yourself from drinking water at least 2 hours before bedtime.
