Water spray reduced core temperature by 0.33 °C and heart rate by 6 bpm in older adults.
Compared to control trials, supplemental skin wetting significantly lowered sweat rate and skin temperature changes.
Participants performed light exercise during an ambient heating simulation to mimic heat generation from daily activities.
These findings imply a need for non-air conditioning cooling strategies for elderly populations during extreme heat conditions.

Water spray shows reductions in core temperature and physiological strain in older adults exposed to heat waves, suggesting new cooling strategies.

McKenna et al. (2024) studied this question.
