Have you ever wondered why you’re usually thirsty before bed? You could be fine all the way up to deciding when you’re be going to bed, when all of a sudden – “I really need a glass of water right now.” It’s uncanny! You could even be under the covers, eyes slowly closing, snug as a bug in a rug, and then the thirst strikes.

Did you know there’s a science behind it? The culprit for your sudden bedtime thirst is none other than your body’s biological clock. How? What? Why? Well, the sudden thirst you experience before bedtime is basically your body telling you to stay hydrated throughout the night.

Theoretically, bodies have a built-in feature that can predict when sleep will start. This triggers you into a ‘mini-survival mode’ to seek out resources (such as water) to stay healthy during long periods of rest. So the next time you feel thirsty as you get into bed or wake up in the middle of the night feeling parched, you now know why!
