does atmospheric temperature affect human body temperature?

it does, but that is why we sweat to try and keep our temperatures down. and that is why if it gets to hot, and we dont keep ourselves cool, we can get heatstroke and some poeple die

could be. as we are more and more able to effectively control our environment we find the average temp of the world we live in is higher. this will effect our average body temp.\nBut.. the sedentary thing would tend to infer we are cooler now. However, on average.. buggered if I know.\nWould be a good bit of research.\nthe global warming goons would love it!!!!

The average temperature of the troposphere (0 to 6 miles above Earth) is 59-degrees Fahrenheit.

Yes, that is fine and within the normal range.  Although the quoted average is 98.6 degrees F (37 degrees C), it can vary by several degrees higher or lower.  Your temperature will vary depending on different factors, such as your metabolism and how fast or slow it is, time of day, if you've exercised recently, etc.\n\nThis also will depend on which method you have been using to take your temperature.  Typically the most reliable temperature reading is either tympanic (your ear) or rectal.  Rectal temp is more reliable because it is more invasive, and it is going to give you a higher reading of your temperature than an oral reading as it is closer to your body's core.  Least accurate, and the one that will give you the lowest temperature reading, is axillary temp (underneath your armpit) as it is the least invasive.  So another thing to consider is whether you have been using the same thermometer and the same method--tympanic, rectal, oral, or axillary--to obtain your temperature, and whether or not it has been the same time of day every day, etc.\n\nSo the bottom line is, generally you should not worry if you think your temperature is low, as what is regular for one person can be higher or lower than the average.  If you still are concerned, though, you may want to consult with your doctor.

If you are in good health, are staying hydrated and are not outside in excessive temperatures, your body is supposed to be able to regulate your body temperature by sweating.  That prevents our temperature from going up significantly during sports and exercise.  (It's also a basic definition of warm blooded...we maintain a stable temperature when our bodies are working they way they are supposed to.) You are more likely to get brain damage from a concussion gotten while playing sports ; )

No. There is no connection between high blood pressure and changes in body temperature. If you experience changes in body temperature, perhaps you have an infection that has nothing to do with your blood pressure.

Atmosphere has a very low heat capacity compared to hydrosphere. It will react strongly on short term (well below diurnal) changes, like insolation (amount of energy absorbed by the sun).

I have to disagree with bobpegoh.  Wind chill DOES change the actual physical temperature of anything that has moisture. Nor is it a matter of simple heat transfer, although that can come into play.\n\nThis is the basic answer to your question - your skin has moisture but the outside of the pipe (where the wind hits) is dry.  If on a windy day you were to put something that absorbs water easily outside, you would feel the item cool in the wind.\n\nThe chilling effect is caused by evaporation (see the link below).  The physics is complicated, but basically when the humidity is below a certain point, water will evaporate and use some of the heat energy in your skin to accomplish that.\n\nPractical exercise.  Take a small wash rag and get it wet, squeezing out excess water.  Swing the rag  in a circle as fast as you can for a minute or so.  When you stop, the rag should be noticeably cooler than when it started.\n\nHow much of the heat energy depends on the relative humidity* - as the humidity gets lower, it takes less energy for the water to evaporate, so it doesn't cool down as much.  When the RH gets higher, evaporation will take more energy until the point where there is too much humidity and the water stops evaporating altogether.\n\nRelative humidity and evaporation are a critical part of our bodies ability to regulat heat.  Our bodies actually generate quite a bit of heat just on normal stuff like breathing and circulating blood, and without a way to cool down, our bodies would overheat.  One way we do this is to take advantage of evaporative cooling by sweating.  Wind increases the cooling and blows warmed, humid air away from our body.  \n\nThis is why weather people talk about "heat index" - when the temperature and  humidity get high, our bodies can't dump the excess heat without help.  The heat index is a comparison of how easily our body can dump heat at the current temperature and humidity vs. the current temperature and a standardized humidity.

Air is denser the lower you go on the earth, due to gravity pullin gthe air down. As you move up, there is more "room" for the air to expand. Air temp is just the measure of the net kinetic energy of the molecules of air. The faster and more there are, the hotter it is. therefore, as the air expands as it moves up into the atmosphere, it cools. On top of a mountain, there is less molecules actually hitting your skin, so it feels very cold.

If there was no sunshine and no vertical air motion, cold air would settle to the surface, and temperature would increase going up in the atmosphere (and we'd all be dead soon ;) ). Because the ground is always radiating away heat (though often receiving more during daytime from the sun), there is a tendency for that to occur. Note the polar regions for example - during winter there is a semi-permanent temperature inversion (increase of temperature with altitude).\n\n2 things which counter the tendency for inversion are solar heating and vertical air motion.\n\nSunshine heats the ground, heat is conducted to air directly above the ground, and convection transports it up into the atmosphere. Cooling/heating of air by radiation is a slower process, so heat builds as spring and summer progress (at mid & high latitiudes) - especially in the lower atmosphere.\n\nAir moving vertically in the atmosphere (up or down) does so at the adiabatic lapse rate, which is 10 °C per km for dry air and less for saturated air (varies depending with temperature - averages about 6-7°C per km). Rising air cools at that rate, and subsiding air heats at the rate. Thus vertical air motions act to heat the lower atmosphere and cool the higher.\n\nThe combined effect of those, as a few people mentioned, is that temperature on the average decreases with altitude in the troposphere - at a rate of 6.5 °C per km (3.6 °F per 1000 ft.). Yet the lapse rate varies depending on conditions. Air during a clear night normally increases directly above the surface, strong inversions may occur during winter and ahead of warm fronts, and air can decrease at the dry adiabatic rate or briefly greater during a warm, sunny spring day. Etc.

the circulatory system (ie the blood circulatory system) can maintain the temperature of the body by vaso-dilation and vaso constriction of the blood vessels ( both deepseated and superficial) when there is cold or the weather is hot respectively.

Exercise involves lots of aerobic respiration, which is WORK, esp as all the muscles are contracting=WORKING.  98.6F is an approximate temp. we do NOT stay there all the time and our temp changes all day depending what we are doing.  In fact in females who are not on the pill or other hormones, the body temp fluctuates all during the month due to the different hormones in the blood (say 96 to 99 deg F) , but 98.6F is "normal" homeostasis body temp for the "sleeping-idle person...we are close to homeostasis at this temp, but during exercise, the body temp will naturally go up, but the body wants to cool you off so you don't FRY-COOK-DENATURE all your metabolic enzymes and go into HYPERTHERMIA.  If you are in good shape you may be able to cool off better than others!\n\nThis cell respiration process during exercise produces lots of ATP and body-muscle heat, which is lost as well. Body needs to cool off from doing all this WORK!  Skin can help us with thermo-regulation in several ways.  When we sweat, the moisure of sweat plus the heat helps reduce body temp by evaporative cooling.  Also,when we get red-overheated,the blood goes to perpheral circulation in skin to bring blood-heat to the surface to be lost by convection with the air currents.  Heat can also leave skin by radiation too.  You can feel heat coming off red sun burned or fevered people.

Everyone's is, because of our body temperature!

Your body burns fuel to get the energy it needs to function. Just like any other combustion process, this generates heat. Since metabolism happens constantly, your body constantly generates heat.\n\nIn order to keep a constant temperature, your body has to balance heat production against heat loss. It turns out that this is easiest when the air temperature is less than your body temperature, since you will lose excess heat to the air. That's why around 75F (25C) tends to be comfortable for most people.\n\nIf the air temperature is the same as body temperature, you can only loose metablic heat through the evaporative cooling provided by sweating. This isn't as effective a process, so temperatures near body temperature aren't generally comfortable. \n\nIn fact, if the temperature is enough hotter than body temperature, sweating is no longer sufficient to maintain your internal temperature. As a result, the heat quickly becomes fatal.

Yes.\n\nThe body cools itself by evaporation of perspiration from the skin.  In dry air, perspiration evaporates rapidly causing a cooling affect but in humid air, perspiration evaporates less quickly so you don't feel as cool.  You'll feel warmer at the same temperature in a humid climate.\nhttp://en.wikipedia.org/wiki/Humidity#Effects_on_human_body\n\nIn it's simplest form, the "heat index" attempts to capture this property of perceived temperature by factoring humidity and temperature into a single value.\nhttp://en.wikipedia.org/wiki/Heat_index\n\n\nSome of the weather services such as Accuweather have devised ways of expressing the perceived temperature that include multiple factors including: "ambient temperature, wind speed, solar intensity, humidity, precipitation intentisty/type, elevation, and atmospheric pressure".  The purpose of this is to try and include all factors that might affect how we perceive temperature.\nhttp://www.accuweather.com/iwxpage/adc/help/pr_realfeel_pr.htm\nhttp://wwwa.accuweather.com/company.asp?page=about\n\nWeather.com has their "Feels Like" temperature rating which is similar.\n\n\nOf course, there are situations where it is so hot that it doesn't matter about the humidity.

Ear SKIN is highly vascular and highly responsive to both emotional states and body temperature changes.  Blood helps with thermoregulation to protect skin-body from overheating or freezing. Some folks' skin is much more sensitive than others too.  Individuals can also vary on a daily basis how sensitive their own skin is from daily emotions or temp.
