Stop blaming the water: here’s the real reason you wake up at 2 a.m.

Sleeping position: a detail that changes everything

It’s rarely considered, yet posture greatly influences sleep quality. Sleeping on your back can promote a redistribution of fluids towards the center of the body, making the organs more active at night.

Sleeping on your side – especially your left – generally improves comfort. With a pillow between your knees, your muscles relax more, promoting more restful sleep. A small change, a big difference.

The microclimate of your room: an underestimated factor

You’ve probably noticed that you sleep better in a slightly cool room. This isn’t a coincidence. A room that’s too warm prevents your body from reaching its ideal resting temperature, which disrupts sleep.

Conversely, a room that is too cold can trigger an adaptation reflex: your body rebalances fluids differently, which can lead to… waking up during the night.
