Cognitive boost from exercise may last into the following day, researchers say

For the morning runners, the cycle-to-work commuters and those who start the day with a brisk walk, the benefits of banking some early exercise are well understood.

Now scientists believe activity is not just a way to improve the day ahead; exercise could also be associated with a small increase in memory scores the next day, too.

A study from University College London has shown that 30 minutes of moderate to vigorous activity and sleeping for at least six hours at night could contribute to improved cognitive performance the following day.

"The takeaway is that physical activity is good for your brain, and good sleep helps that," said Dr Mikaela Bloomberg, first author of the study.

The researchers noted that physical activity has previously been associated with both short-term improvements in cognitive function as well as a reduced risk of dementia.

However, Bloomberg said that many studies looking at short-term impacts had been laboratory-based, and primarily tracked responses on a timescale of minutes to hours.
