We underestimate how much our mood is affected by light and air. Spending entire days in closed, artificial environments can leave you feeling foggy, low and restless without understanding why.

Natural daylight helps regulate your body clock. Morning light in particular signals your brain that it’s time to be awake, supporting alertness and better sleep later at night. Even 10–20 minutes near a window or outside can make a difference.

Fresh air – away from heavy indoor pollutants, stale air and strong smells – can lift your energy. A short walk outdoors, balcony time, or even opening windows for cross-ventilation reduces stuffiness and gives your eyes a break from screens.

If you work from home or in an office, consciously schedule small “light and air” breaks. Stand near a window, step out to the terrace, or walk around the building. It’s not just about oxygen; it’s about giving your senses a reset.

These small habits are simple, free and often surprisingly powerful for clearing mental fog.
