Mental Effects

Mike Carruthers discusses how caffeine is commonly believed to enhance mood and cognitive function. However, recent findings from John Hopkins Medical School suggest that these perceived benefits are actually due to alleviating caffeine withdrawal symptoms. This means that the morning boost from coffee merely brings regular drinkers back to their baseline performance levels.

The caffeine that you drink in the morning is just bringing you back to normal after the effects of caffeine withdrawal overnight.

This revelation challenges the long-held belief that coffee inherently improves mental function 1 2.

   

Withdrawal and Performance

Caffeine withdrawal significantly impacts cognitive performance and mood. Carruthers explains that the negative effects of caffeine withdrawal overnight reduce cognitive abilities and mood, which are then temporarily restored by morning coffee. This cycle suggests that non-coffee drinkers do not experience the same cognitive boost from caffeine.

If you give coffee to someone who doesn't drink coffee in the first place, their cognitive performance will not improve much, if at all.

--- Mike Carruthers

Understanding this cycle can help coffee drinkers make more informed choices about their caffeine consumption 1 2.
