It’s easy to blame low productivity on the weather, especially if you live in the usually bustling city of Nairobi. On rainy days everything slows down. Even the toughest of business tycoons bundle up in their “el niño best” and adopt an easy going attitude until the storm passes. ‘But what if you found out everything you lead yourself to believe could be wrong.

“PEOPLE TEND TO BE MORE PRODUCTIVE ON A BAD WEATHER DAY THAN ON A GOOD WEATHER DAY.”

A study of 136 Harvard college students were divided into two separate groups – rainy-day participants, and sunny day participants. The students were then asked to perform a series of tasks. The researchers found that the top performers (those who completed the task the fastest and the most accurately) were the rainy-day control group participants.

The only catch? Researchers also found that the controlled group of rainy day participants who were shown pictures of artificial sunlight like a picture of the beach or people camping were less productive than their counter parts who were exposed to no sunlight at all.

“The findings indicate that workers are indeed most productive when the weather is lousy—but only if nothing artificially reminds them of good weather.”

So, the good news is you’re probably more productive on rainy days than you think. In part because you don’t have the distraction of a beautiful day outside your window. The bad news? You should probably put away your “20 most beautiful beaches and babes” calendar.
