You lose a similar amount over any given exposed area of your body and only slightly more through the head due to a higher concentration of blood vessels close to the surface and a smaller percentage of fat.
The common misconceptions are that one loses between thirty and eighty percent of body heat through ones head. The reasons behind this are two-fold.
Firstly, people seldom wear hats or head-coverings until cold conditions becomes fairly acute. However, we seldom run around without clothes in all but both the hottest weather and liberal surroundings. At most points a person will have the majority of their surface area covered with clothes. If it were bitterly cold you would be unlikely to roll up one sleeve, but this would lose a similar amount of heat.
Secondly, your head contains your brain. Your body protects your brain in the same way as any major organ. It withdraws blood from non-essential extremities to concentrate on the core of the body and, of course, your brain.
You feel the cold in these areas last but more often than not the body will have to work harder to protect the head due to clothing on the torso and limbs as well as socks, shoes and underwear. Your head feels cold in order of essentials as well, the ears nose and then lips before the core.
It is possible that you lose about thirty percent when moderately clothed through your uncovered head, but then it is also possible that your head loses less than any other area when naked due to the insulation properties of your hair.
What else can I help you with?
Where do you lose the most body heat?
The most body heat is lost through the head, followed by the hands and feet.
Where do you lose the most body heat?
You lose most of your body heat through your head. This is why cold-weather places often have extreme solutions to keep the head warm such as a scarf, scull cap, or fur headresses.
Where do you lose most of your body heat?
The majority of body heat is lost through the head, as it has a high surface area and is often left uncovered.
Do you lose a lot of body heat through your hands?
no
How much heat can you loose through your head by not wearing a hat?
While the idea that we lose most of our body heat through our head is a myth, not wearing a hat in cold weather can still contribute to heat loss. The amount of heat lost through the head will depend on factors like temperature, wind speed, and individual metabolism, but wearing a hat can help maintain body temperature and prevent excess heat loss.
How do you lose body heat?
mainly through you skin and breathing.
How can the body lose heat from radiation conduction and convection?
The body can lose heat through radiation by emitting infrared radiation from the skin. It can also lose heat through conduction by coming into direct contact with cooler surfaces, transferring heat to those surfaces. Additionally, heat can be lost through convection when air or water makes contact with the skin and carries heat away as it flows past the body.
What three ways do you lose heat?
You can lose heat through convection, where heat is transferred through air or water currents; conduction, when heat is transferred through direct contact with a colder object; and radiation, when heat is emitted as infrared radiation from your body.
What percent of body heat is lost through your head?
I gotta go with the NY Times on this one. It would seem that it's not entirely true. Body heat escapes through any exposed surface. The larger the surface, the more heat that escapes. If you have less hair, naturally, you'll lose more heat through your head (I happen to shave mine, so I know!) http://www.nytimes.com/2004/10/26/health/26real.html
From which three body parts do you lose most of your body heat?
hands, head and feet. about 70 to 80% is lost thru the head. the rest can be lost through the extremities. your nose is fourth in line because you respire warm air out and breath cold back in, which chills the body. James
What process can humans lose heat but not gain it?
Humans can lose heat through processes such as conduction, convection, radiation, and evaporation. However, humans cannot gain heat through evaporation because it is a cooling process where heat is transferred from the body to the surrounding environment.
How does your body lose heat through urination and defecation?
Heat loss through urination and defecation occurs due to the high water content in urine and feces. When urine leaves the body, it takes away some heat with it. Similarly, when feces are eliminated, they also carry away a small amount of heat. However, the overall amount of heat lost through these processes is relatively small compared to other mechanisms such as evaporative cooling through sweating.
