	Evaporative spray cooling can improve thermal comfort and provide relief from thermal stress, even in a subtropical climate such as Japan. An experiment was carried out that combined a water mist spray with a fan and assessed its impact on the comfort of 141 participants on hot summer days. Participants were visitors to a public event held on 10–11 August 2013 in Osaka, Japan.

	This technology has the potential to reduce heat stress and discomfort, particularly at large outdoor events and festivals. It could also reduce cooling loads within buildings by providing inhabitants with thermal relief outdoors. Continuing research will measure the effects of misting fans on people engaged in moderately strenuous activity in hot conditions.

−	It was found that the cooling effect was highly efficient. The forced convection of the fan helped cool the skin and accelerate the evaporation of mist droplets that had adhered to skin and clothing. This produced an almost instant decrease in skin temperature. The mist and fan combination ~~achiever~~ localised cooling rates of more than 200 W/m2. Exposed skin temperatures could drop 2 K within 10 s with light wetting and were 1 K cooler even after leaving the mist. There was no correlation between time spent in the mist and degree of effect.	+	It was found that the cooling effect was highly efficient.
