why do people say it a humid day when it is very hot ?

Question

whereas after a good rain when humidity is actually very high people seldom say that a humid day...yes it is correct that high temperature causes greater evaporation and that vapour increases humidity content of the local atmosphere ...but from my standpoint degree of humidity in this case will never be greater than the degree of humidity after a heavy rain .
please refrain from doing non-scientific answers . And please answer !

Answer 1

Scientifically you may be right but the way the human mind thinks is not all the time scientific. When it is hot a human body perspires more and that gives one a feeling that the perspiration does not evaporate because of the humidity. Does this make sense.

Answer 2

Humidity and high temperature have nearly the same relative effect on air density. As the humidity or the temperature increases (or both), air becomes less dense. Breathing takes noticeably more effort, and the additional effort feels like a heaviness in the chest. High temperature and high humidity are really noticeable. People tend to remember hot days when breathing was easier than on hot, humid days. This association tents to make people blame humidity rather than temperature increase for the increase in breathing difficulty although the humidity may be low.

Answer 3

You notice the humidity when it is hot, and you're not experiencing much evaporative cooling by sweating.

Rain occurs because the temperature has dropped, and water vapor has precipitated. Because the temperature has dropped, you are in less need of evaporative cooling.

Incidently, the rain stops falling because the relative humidity has dropped below 100%; it's more humid at the start of a shower than immediately afterwards.

Answer 4

Humans are really good at cooling down by perspiration. See http://www.physorg.com/news95954919.html

At elevated temperatures perspiration and moisture loss from respiration are essentially the only natural ways for the human body to lose heat. These methods are more effective if the relative humidity is low. As the relative humidity rises getting rid of heat through perspiration becomes more difficult. People can acclimatize to hot but hot and humid presents a much grater challenge. If the temperature is above body temperature and high humidity is eliminating the possibility of evaporative cooling people must resort to some other method of cooling themselves or they will parish.

Answer 5

if you lived in florida, you would know the answer to this question. because after it rains, it's hot as heck, lol.

Answer 6

More simple to say it, just comes out is all
