I'm sick of hearing how cold it feels in the winter and how hot it feels in the summer. So what does it take for our skin to agree with the thermometer - no wind and 50% humidity?

Some confusion in this regard. True temperature is easy to get at, unlike the above answer. Just jump in a pool. What you feel is very close to the actual temperature of the pool. But, notice how when you do jump in a cool pool, that after swimming around a bit you don't notice the cold? Your body can change how you think you feel, even when the environment is exactly the same.

Now, the problem with the air is simple. If the air is humid, it is able to 'hold' much more heat. This mean that in cold weather, you get cold faster, and in hot weather, you heat up faster. It also affects the human body in hot weather because our cooling mechanism depends on evaporation. And that is far less efficient in high humidity.

Evaporative cooling is aided by wind, so the opposite situation results in hot climes. Hot dry and windy can be quite comfortable. In cold, wind continually removes the warm air around your body, causing you to cool faster.

In all of these cases, a thermometer will give you the true temperature. But that doesn't equate to a comfort level unless you have the other information (wind, humidity, radiation). Hope this helps some.

Sorry--your skin (nerves really) do not measure temperature. Your skin informs you of changes in temperature, not what the temperature is. Depending on conditions (i.e., humidity, pressure, wind, etc...) your skin is telling you whether you're radiating heat (losing it and getting colder) or getting hotter. "Temperature" is an arbitrary scale that records the effect on bands of metal that expand or contract with changes. It has no connection whatsoever to the way your nervous system operates, or the way your body reacts to the environment.

Just knowing temperature is next to useless for most purposes. That's why pilots had to agree on what consitutes a "standard day" which is a fixed point of reference so that we can estimate what our planes will do in different weather conditions.

All of that is to say that there is no such thing as "true" temperature, unless you're a piece of metal.

110 degrees. Stand in the middle of Death Valley on a windless sunny day. Humidity 2 %. It feels like 78 degrees F.

Any wound, no remember if stitched or not, heals extra useful and swifter while it is lined with a sterile bandage. opposite to consumer-friendly perception, leaving it uncovered to the air does not help. quite, it will enhance the prospect of micro organism getting into touch with the wound, which might in basic terms lengthen therapeutic.
