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
What else can I help you with?
What percent of body heat escapes from you head?
Here's what I found on a website "Depending on which website you believe it is anywhere between 20% and 90%.However it appears that the big difference is accounted for by the prevailing circumstances.Conduction and convection about 25%Radiation about 43%Evaporation and moisture about 30%Exhaled air about 2%Evaporation prevails at high ambient temperatures. Conduction and convection prevail at low ambient temperatures."The generally accepted overall amount of heat loss through an uncovered head is about 40%, which is substantial. Wearing a hat can make a big difference in how cold you get overall, and how fast you get cold.
What will take in more heat R-5 insulatation or R-35 insulation?
R-5 insulation will take in more heat compared to R-35 insulation. This is because the R-value measures the insulation's resistance to heat flow; a lower R-value indicates less resistance and therefore allows more heat to pass through. In contrast, R-35 insulation provides significantly greater resistance to heat transfer, making it more effective at keeping heat out in summer and retaining warmth in winter.
Why is kettle not 100 percent efficient?
There are many factors that affect the loss of energy:1 the resistance of the wire2 the kettle will keep most heat in but not all heat within the kettle so more energy is lost3 the water will evaporate out the top and that is also a cause. (they can't close it off otherwise the pressure would build and it would explode).
How many square feet does a 120000 BTU heater heat?
Square feet has nothing to do with how much an X BTU heater can heat, heat is calculated by determining how much heat LOSS there is to make up for. AC is the exact opposite, it's size is determined by how much heat GAIN there is. In general, a 120,000 BTU boiler can heat an average well insulated 2 story house, no problem. There are many programs that calculate heat loss/gain but since there are people who do it for a living, try asking one.
How many btu needed to heat 625 sq feet?
btus needed to heat & cool 625sf room
Through what part of the body is nearly 50 of a person's body heat lost?
Nearly 50 of a person's body heat is lost through the head.
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 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.
Does Body heat escape through the ears?
Yes, body heat can escape through the ears as they have blood vessels close to the surface of the skin. This allows heat to dissipate from the head, which helps regulate body temperature.
What is a part of the heat-liberating apparatus of the body?
Most heat exits the head, most of the rest is through water sweated through the skin.
What are the two ways heat is removed from your body?
Through sweat, through the top of your head, bottom of your feet, through your hands.
Where does most of the heat come from in the body?
Most of the heat in the body is produced as a byproduct of metabolic processes, especially in organs like the liver, brain, and heart. Additionally, muscle activity such as shivering or exercising can generate heat.
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.
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.
Why child's ears heat up suddenly?
body heat is released primarily through head, face, ears, hands and feet.
Can head shave heat up the body?
No. It does not heat up the body. On the contrary it keep your head cool by reflecting the light. Lol.
Where does the heat that your body gives off go?
The heat that your body gives off is mainly lost through radiation, convection, and evaporation. Radiation involves the transfer of heat through electromagnetic waves, convection occurs when heat is transferred through the movement of air or liquid, and evaporation helps in cooling the body through sweat that evaporates from the skin.
