 Yeah, that's certainly what the evidence is suggesting at the moment. Doesn't seem fair. They do require a little bit more. There are additional complications with females in relation to how they cope with the heat. When we are working at very, very high workloads, we know that females are not as effective at producing the maximum amount of sweat that males can. So males will sweat more. We also see changes across a female's monthly cycle that cause changes in our thermoregulation.
