The old myth about losing most body heat from the head has been debunked by experts, leaving many of us to wonder where this notion originated.
According to John Tregoning, a professor of vaccine immunology at Imperial College London, the idea that our heads are uniquely prone to heat loss likely stems from a 1970s US Army Survival Manual. However, Tregoning disputes this claim, stating that there is nothing inherently special about the human head.
In reality, we lose more body heat from areas that are left exposed than those protected by clothing. If you venture out in cold weather without wearing a hat or covering your face, you'll lose heat just as quickly from these uncovered areas. Clothing plays a significant role in slowing down the cooling of our bodies.
For instance, if you're dressed in a snowsuit but forget to wear a hat, you'll still experience rapid heat loss from your face and head – not because of its unique properties, but due to its relatively small surface area. In contrast, areas like the legs have a greater surface area, making them more susceptible to heat loss.
While there is some debate about whether our heads are indeed more prone to heat loss, Tregoning points to research suggesting that we lose less heat from our heads due to their lower fat content compared to other parts of our bodies. However, this supposed advantage in insulation is offset by the fact that vasoconstriction – a natural process designed to conserve heat – is less effective on the head.
Recent studies have further dispelled the myth, with researchers finding that the speed at which we cool down when our heads are submerged in cold water doesn't significantly differ from other parts of the body.
So, what's the takeaway? While it's true that you'll lose some heat through your face if you're not wearing a hat or covering it up, it's by no means as critical an area as previously thought. If you're braving extreme cold without proper gear, prioritize covering your entire body – including your face – to minimize heat loss and stay safe.

I mean, it makes total sense that clothing would play a huge role in keeping us warm, but come on, who forgot about that? 
And now that we know vasoconstriction is actually less effective on the head, it's like, no wonder people didn't catch on sooner 
Anyway, can we just focus on dressing up and covering up instead of wasting time trying to debunk myths about our bodies? 
I never knew that myth was busted! 
It makes total sense now, I guess I've been wearing hats just for the aesthetic 
. Anyway, now that we know the truth, let's all prioritize covering up in extreme cold 
!
. The idea that losing most body heat from the head is a thing of the past now makes total sense - it's all about where you're exposed, not what part of your body you're wearing 
. I can imagine how easy it must have been to come up with the original myth back in the 70s... who needs facts when you've got a manual on survival? 
. Anyway, makes sense now that you know the truth – clothing is way more important than which part of your body you lose heat from 
. clothing is actually whats savin u from losin too much heat, not da head itself 
. i mean, if u wear a snowsuit but forget ur hat, u're still gonna lose heat from ur face and head, it's all about da surface area 
Interesting how something like this gets passed down through the years and becomes so ingrained in our minds 
anyway now that we know the head isn't the worst for heat loss maybe we should focus more on wearing cozy clothes instead of just hats?
. It's actually our exposed areas that are more prone to heat loss than our protected ones. Like if you're out in the snow without a hat or scarf, your face and head will lose heat just as fast as any other uncovered area. Clothes play a big role in keeping us warm, so even with a fancy snowsuit, forgetting a hat can still leave you feeling chilly pretty quickly 
. So yeah, I guess our heads aren't really the cold-burning machines we thought they were 
, it's crazy how a seemingly obvious fact can be so... wrong 
. Prioritizing body coverage is a no-brainer now 
, makes sense that we should cover up all exposed areas, not just the head 
. I'm glad to see researchers like John Tregoning shedding light on this topic and helping us separate fact from fiction
