Connolly, D. A., & Wilcox, A. R. (2000). The effects of an application of suncream on selected physiological variables during exercise in the heat. Journal of Sports Medicine and Physical Fitness, 40, 35-40.

The application of suncream on mean skin temperature, rectal temperature, oxygen consumption, and heart rate during exercise in the heat was investigated. Males (N = 22) performed for 40 minutes at 55% VO2max at 32 degrees Celsius under two conditions; with and without suncream.

Mean skin temperature was lower and mean core to skin temperature gradient was greater when suncream was used.

Implication. Suncream application does not impair heat dissipation when exercising in the heat.
