Explain this :

Scenario : Shower. Room temperature is 70f.

Why is it that in the summer, when you get out of the
shower you start to sweat and in the winter you get out
and it's cold ?

I have changed the title because these are really stupid things
to think about . Which in retrospect, makes me stupid .

The colder it is outside, the less relative humidity the indoor air will have (due to the fact that the capacity to store water increases for air with increased temperature, and while the absolute humidity of air will be the same when your house ventilation system takes the outdoor air and heats it up before releasing it inside, the relative humidity will increase, since this concept is based on the amount of humidity being bound in the air in relation to the current capacity of the air to store water/humidity).

Since the cooling of the human body depends on how fast water (i.e. shower water in this case, and sweat in the case where the body itself tries to cool down an overheated body) evaporates from your skin (which in turn is a physical phenomenon coming from the fact that a material will need to absorb energy to transform from liquid state to a gaseous state, and this energy will be drawn from any nearby material, which in this case is the body on which the water resides), with more efficient cooling the faster the water evaporates, you will be cooled more (and thus freeze more) the bigger the difference is between the outdoor temperature and the indoor temperature (since water will evaporate faster the lower the relative humidity of the surrounding medium is), all other factors being equal.

This physical phenomenon would most likely play a relatively large part in it at least I would guess.

Now, how many people read my post but skipped Delta's - that's what I am thinking about

Hi Buddha

So how can the relative humidity in a 5 X 10 foot bathroom
be affected by the season ?
The shower itself creates the relative humidity in the bathroom doesnt it ?

Tsk Tsk another stupid thread from Wood
You have forgotton to zipped up your zippers

Zipper instruction -

To open, 1. Grasp handle - thiis is usually found at the top of the zipper.
2. swivel handle outward.
3. pull down firmly and slowly
4. should an obstruction prevent full opening call our tech service at
1-555-555-000, a customer assistant will be able to help you in a
short period of time.
5. Should the issue resolve itself you may sneak out of the restroom
and call us at a later date to fix the problem.

As explained above, the season (or rather the outdoor temperature) will unavoidably affect the relative humidity of any areas inside your house that contain breathable air, which should include your bathroom, no matter its size.

And yes, the showering helps to increase the humidity of the nearby air when you use it, but it also increases the temperature of the air in your small bathroom, which in turn will decrease its relative humidity. I couldn't say exactly how much each of two these factors contribute "in opposite directions", but what I can say is that you don't get cold the exact second you turn off the shower do you, but rather when you step out of the shower, which also happens to be the moment when you are exposed to air that has not been as much affected by the showering activity as the air that surrounds you in the immediate area of the shower itself, even though you might even still be inside the bathroom (but if you step out of there too, the difference will be even more apparent, right?).

On a stupider note, almost 30 years ago, I proposed embedding heating elements in the bathroom mirror, powered through the hinges, to keep it's temp above the dew point, ( I hated clearing the condensation off before I shaved), I was laughed at , they now sell condensation free mirrors. (heated). AHHH shit I always get cheated.

Why are those arthritis creams made from Capsazin labeled "for external use only"???? I'd love to be there if someone stuck it in an orofice or two.

@esther..........C'mon, you have more to offer than that.

@dELTA..........I suppose you are correct BUT, it is not logical.

@SiG............. Show me the zipper instructions.

I suppose I will have to do some research as to why this shower thing happens.

What if it is pyscological ? Maybe I think it is colder in the winter?

Howdy ,
My explanation is plain simple,with some scientific logic .Just an example your
body temp is 98.6F when you shower and outside the bathroom temp is 95F.
when you shower,your body temperature might be rising,to 98.6F to reduce the heat,
the skin pores open and rls the heat to cool down you body temp,after you shutoff
the tap your body temp will simply drop back to normal temp or lower since your
body is rlsing the heat.In winter when you stepped out of the bathroom,
you will feel cold since your house temp is 95F

Woodmann,

As far as zippers go, I tend to avoid them - we've all had bad experiences with them - sometimes painfull - with buttons in an emergency you can just rip the suckers open - the instructions are purely mine., As for your shower dilemma, aside from your body temperature, you are deluged with a hot water stream and covered with a natural coolant once the water is off due to evaporation. the floors and other parts of the bathroom take a lot longer to warm up than your body, I still reminisce about the small electric, (very dangerous), heater that used to be in bathrooms in older houses.
