Summer officially arrives tomorrow.
And if your brain seems to wilt in the summertime heat, there may be a reason.
Studies have shown that when the weather is nice, people tend to focus on what they'd rather be doing instead of the task at hand.
In fact, one Harvard study found just showing people pictures of nice weather affected productivity.
Other studies show working conditions that are hot and muggy may also reduce our attention and energy levels.
"From the time we're pretty young we've developed impressions that summertime is associated with more leisure, less critical thinking, less requirement, and we really live that out," said Scott Bea of the Cleveland Clinic.
Doctors say the summer months are a good time to take a break because your brain wants it anyway.
