Many people complain of more back problems and stiffness in the morning during the winter than in the summer.
What are the reasons for this phenomenon?
Sleeping with the window open is pleasant. We simply prefer the fresh air to the stale smell that develops when we leave the window closed at night. Understandably, we use a warmer blanket during the cold season because otherwise we’d freeze. But that’s exactly where the big danger lies. Under a really warm blanket, there’s a risk that we’ll suddenly start sweating and pull the covers off. If cold air then flows into the room through the open window during the cold night, a “pool of cold air” forms near the floor. Cold air is heavier than warm air and sinks. Covering yourself now and lying in this cold air with very warm, sweat-moistened skin—or even continuing to sleep—can easily cause rheumatic pain or stiffness. These symptoms are particularly noticeable when getting out of bed. This often explains why many people suffer more from stiffness and pain in winter than in summer.
Important: When the window is open, the air moistened by our breath flows outside. In return, we let dry, cold winter air into the bedroom. As a result, the mucous membranes dry out and our noses get stuffy. This happens much less often when the window is closed!
