A new article published this week in Psychology and Aging (Mantantzis, Konstantinos, Maylor, et. al.) found that providing glucose as an energy source through a sugar drink helped increase heart rate associated with higher task engagement. More importantly, the increase in glucose levels also improved cognitive performance on a memory test at various levels of difficulty while also increasing positive affect (emotion) in the adults. So this might suggest that having a quick sugar fix before you need to perform cognitively (e.g. filling out your taxes, etc.) or when you need to put on your happy face – might be just the trick.
