Despite having comparable levels of caffeine in the body, females exhibited significantly greater caffeine-induced impulsivity than males.

New Delhi:Are you someone who reaches for a cup of coffee every night? According to a new study, nighttime caffeine consumption can increase impulsive behaviour, potentially leading to reckless actions, especially among women.

The findings could have negative implications for shift workers, health care, and military personnel who consume coffee at night, particularly females, said a team of biologists from The University of Texas at El Paso (UTEP).

The study, published in the journal iScience, examined how nighttime caffeine intake affects inhibition and impulsivity in fruit flies.

Drosophila melanogaster, the fruit fly species used in the study, is a powerful model to study complex behaviours due to its genetic and neural parallels with humans.

The team designed a series of experiments introducing caffeine into the flies' diets under various conditions, including different caffeine doses, nighttime versus daytime consumption, and in combination with sleep deprivation.
