Mike Tipton, PhD, professor of human and utilized physiology on the College of Portsmouth Excessive Environments Laboratory in Hampshire, U.Ok., has spent many years consulting with the army, business, and elite athletes on methods to keep up their “cool” in excessive environmental conditions. However maybe considered one of his most essential classes got here from the least anticipated place: Nineteen Seventies housewives.
“A few years in the past – in all probability 50 or so – housewives used to say that after they obtained scorching gardening or doing one thing exterior, they’d are available and run their palms beneath the chilly faucet,” Tipton defined.
“So after we have been on the lookout for one thing for the Navy firefighters who’ve to enter very popular compartments carrying a whole lot of protecting clothes, you begin with how the physique works. And we discovered that sticking their palms into chilly water was as efficient as anything we might do for them.”
Earlier than Issues Get Out of Hand …
Peripheral blood move – how and the place blood is transported by the physique – is essentially decided by deep physique temperature. When it will get scorching exterior the physique, the mind instructs blood vessels to divert blood move to pores and skin to help in sweat and evaporation to make sure that the core or deep physique temperature stays optimum.
“The palms are superb warmth exchangers as a result of they’ve a excessive floor space to mass ratio,” mentioned Tipton. “Hand immersion is a very great way of cooling the physique.”

“Clothes acts as a barrier for lack of warmth from train,” mentioned Tipton, referring to troopers as a primary instance.
“Once you [think] in regards to the army, they’re carrying protecting clothes and carrying extra load, which will increase their metabolic price and their warmth manufacturing, in addition to impeding it. In that state of affairs, you will get to the circumstances of varied warmth diseases in a short time, [some which are] a medical emergency.”
