Exercise
The government of Canada recommends that people over 18 get 150 minutes of exercise a week to maintain health. This also plays a significant role in executive functioning. I explored how different factors impacted executive functioning, including how often individuals were exercising, how hard were they exercising and what exercise activities were they performing.
People who reported getting six hours of physical activity per week showed improved executive functioning over sedentary individuals. Additionally, those in a high-intensity sprint program for a two-week period not only outperformed a control group in their measures of executive functioning, they also made fewer mistakes.
While standing and treadmill desks did generate improvements to other aspects of physical health after just four days, they did not get the same boost to cognition that was seen with other moderate to high-intensity exercises. This means that if you want those boosts to cognition, you need to really get your heart rate up.

Sleep
It’s also important to consider how much sleep you are getting, as people often reduce their rest for work and social obligations. Although a few studies in the review did find that reduced sleep generated poorer executive functioning, the more common outcome was worse performance across the board. Reduced sleep didn’t impact specific components of attention in the same way that meditation and exercise did. Instead, it made people slower to react and more prone to making mistakes.
However, most of the sleep research included in the review involved keeping people up for 24 hours. This isn’t very representative of how most people experience a reduction in sleep. Future research should consider how people’s sleep quality is impacting their executive functioning. This information is especially important for those who work in scenarios where lapses in attention pose a potential risk, like air traffic controllers or those who operate heavy machinery.
There are many aspects of our cognition that are out of our control. Executive functioning abilities are largely influenced by genetics. However, this review provides promising evidence that there are changes you can make to your daily routine that can provide a nice boost to your focus.
So, if you want that extra edge, start meditating, get your heart rate up and get to bed early!
