Abnormally hot days could have consequences for everyday thinking, a new study from the Yale School of Public Health warns.
After analyzing data from eight years of cognitive tests administered to teenagers and adolescents across China and then matching the test results to local weather data at the exact time of the test administration, researchers discovered that high-temperature days were associated with reduced scores on math tests. The lower test scores represented a learning deficit equivalent to as much as a quarter of a year of education, the researchers said.
