Why do we think more clearly during cloudy days

Sunlight makes the mind dull for risk and thoughtfulness.

Humans are biologically predisposed to avoid sadness, and they respond to depressed moods by looking for opportunities to repair the mood and protect themselves by being vigilant against whatever may make them sad. In contrast, happiness sends a signal that everything is fine, the environment does not pose an imminent danger, and there is no need to think deeply and carefully.

These contrasting mental perspectives explain why shopkeepers remembered ten trinkets more accurately during rainy days; The rainy days prompted a generally negative mood situation, which shoppers subconsciously tried to overcome by grazing the environment for information, which might have replaced their gloomy sad mood with happy choices. If you think about it, this approach makes sense. Mood states are all-purpose measurement tools that tell us if something needs to be fixed in the environment. When we are faced with great emotional obstacles — extreme grief, an injury that brings severe pain, blinding anger — our emotional warning lights glow red and force us to act. For most of the time we walk smoothly through calm water, leaving much of the world — including small trinkets on store countertops — unnoticed.
