Peanut is a potent allergen, but little is known about the factors that contribute to severe peanut reactions. In soon-to-publish U.K. research presented at the allergists’ conference, both exercise and sleep deprivation were shown to have a big impact.

In the study, 126 peanut-allergic participants underwent three challenges, in which they consumed a small amount of peanut and then either exercised, reduced the amount of sleep they got – or did nothing further.

The amount of peanut needed to trigger symptoms was reduced by 45 percent in those lacking sleep or taking part in exercise, compared to those with no intervention.

The preliminary findings, presented at the AAAAI 2019 conference, suggest that individuals with an allergy to peanut should be extra vigilant when eating food prior to and following exercise or when particularly sleep deprived,” said a spokesperson for Britain’s Food Standards Agency (FSA), which funded the study.

The full results of the study are expected to be published in the fall of 2019.
