Why i feel cool when near a lot of trees although it absorb heat from environment still it make environment humid ALSO? Why I feel cool in a region with lot of trees inspite of humidity by transporation?
Today I went for a walk and entered a region with lot of trees, It feel a sudden chill, a cool feeling (comparatively)
Why, Although trees perform transpiration that cause moisture so we should feel warm but I feel cool?
So i search for answer, i got to know that tree absorb heat from surrounding to change liquid water into water vapor through transpiration. But it create a query.
Although environment is cool still! There are lot of moisture too!! Due to transpiration. So how could i feel cool although atmosphere cannt contain much sweat that cause cooling, so according to this i should feel hot, still i feel cool! But how? If sweat cannt evaporate althogh  environment is cool?
 A: The feeling of being cool can happen through two reasons

*

*You are cooling off via sweating/evaporation

*The environment is actually just cold, independent of how you cool yourself off.

The reason you feel cool around trees DESPITE increased humidity is (2). The trees have actually cooled the environment around them via transpirative cooling. So regardless if the humidity of the environment is higher you still feel cool around the trees.

This is actually a very good question. There appears to be two competing factors involved. Evaporative cooling due to transpiration from the trees cools the air, increasing heat transfer away from the skin making it feel "cooler". But at the same time you would think transpiration increases the humidity in the air, potentially interfering with evaporative cooling of skin perspiration, making you feel "warmer"
The fact that you experienced "cool" rather than "warm" suggests to me that the relative humidity (RH) of the air was low at the time, so that it was capable of absorbing the moisture and cooling the air without significantly raising the RH under the tree to interfere with evaporation of skin perspiration, thus making you feel "cool".
If the RH was high, particularly at or near saturation (100%), transpiration evaporation from the tree, and its cooling effect, ceases. Likewise, evaporative cooling of perspiration ceases, both of which would make you feel "warm". For more information on transpiration of plant, see: https://www.polygongroup.com/en-US/blog/how-humidity-affects-the-growth-of-plants/
Bottom line: The higher the RH the warmer you will feel, whether you are under a tree or not.
Hope this helps.
