Humidity on window by hand!?
830318
Everyone has sweat glands in their skin, in every part of the skin.  We are constantly sending off small amounts of water through these glands.  If you want to prove it, wrap your hand in plastic wrap or just put it inside an empty bread wrapper and wait a  few minutes, it'll get moist in there!\n\nWhen skin is put next to a cold window, that water vapor condenses, and fogs up the window.\n\nAnd these glands open more when we get hot and the body needs to cool down.  In your case, your "thermostat" is set differently than your friend's.   But it's not magic, it's biology.

It is too dry in your house ??? try putting a pot of water on your stove top and put it on low and let it evapoate into your house ..

Static electricity gets worse when it's dry... low humidity.  You can't do much about that outside, but you can always get a humidifier for your house. Use moisturizers on your skin, switch to cotton clothing, use dryer-sheets at the laundry, use a metal object (like a key) to touch metal things like doorknobs after shuffling along your rug.  Along those lines, pick up your feet when you walk so they're not sliding.  If no key is available, try grounding yourself by touching something like the wall before touching a metal object or a person (or pet!) Experiment with different shoes.  My leather boots are the worst!

While the math gets a bit complex, relative humidity cannot naturally reach zero percent on the Earth's surface.  Even in Las Vegas, one of the driest places on earth, the relative humidity runs about 11% on a June afternoon.  The lowest relative humidity ever recorded anywhere on Earth was about 2%.  So, no, it is not possible to reach zero percent relative humidity other than in a laboratory.\n\nAnywhere you have fog or rain, you generally have 100% relative humidity, so this is quite a common condition everywhere.

wipe it with a clean cloth, or use compress air

Humidity is the concentration of water vapor in the air. The concentration can be expressed as absolute humidity, specific humidity, or relative humidity. A device used to measure humidity is called a hygrometer. A humidistat is used to regulate the humidity of a building with a de-humidifier. These can be analogous to a thermometer and thermostat for climate control. Due to the changing partial pressure of water vapor in air as temperature changes, the water content of air at sea level can get as high as 3% at 30 °C (86 °F), and no more than about 0.5% at 0 °C (32 °F).

Windex works, so does rubbing alcohol. Use paper towel.

Make sure the suction cups are not misshapen.  The out of shape allows air to get into the seal more easily. \n\nIf they are out of shape, clean them with soapy water, rinse them.  Clean the glass.  Have a container of boiling water nearby.  Drip the suction cup briefly.  It will soften it.  Immediately press onto window glass.  Hopefully it will dry and remove the misshape.

who gives a crap! its yur bathroom! so let it smell the way u want! jus prop open a window...thats what i do lol

I have the same problem - No one has mentioned "environment" (that I saw?) - It's now Spring - What kind of climate do you live in? I'm in CO - and the Humidity today was 8% (Yes, EIGHT percent) - but "cold" so the heater was blasting all night ... so dry air effects me as well as lack of moisture that comes with higher humidity...\n\nOption #2) - Do you take Tylenol PM (or any antihistamines?) - For whatever reasons - these too dry out my eyes (well, B/C they're a type of antihistamine)\n\nOption #3) - People have already mentioned allergies... and alcohol - May wanna check with an allergist about down pillows, or Spring hay fever - or even "mold" if you are in a northern climate, and the windows are sealed - I found my "allergies" were worse in the winter than summer, and never understood this since all plants/trees/weeds and such are "dead" (dormant) - well, turns out Mold in the air ducts was the cause... \n\nIf you go to a Doc, and tell him about using "Clear Eyes" or "Visine" - those too have a "rebound effect" and he'll (she'll) encourage you to go to "natural tears" for the others' can CAUSE red eyes after long term use... But I too still use them, cuz "natural tears" don't remove the red - and don't wanna look hung over at work - When I'm NOT! LOL \n\nCheers and good luck!

Relative humidity is a term used to describe the quantity of water vapor that exists in a gaseous mixture of air and water.\n\nDefinition\nRelative humidity is defined as the ratio of the partial pressure of water vapor in a gaseous mixture of air and water to the saturated vapor pressure of water at a given temperature. Relative humidity is expressed as a percentage and is calculated in the following manner:\n\nRH = {p_{(H_2O)} &#92;over p^*_{(H_2O)}} &#92;times 100%\n\nWhere symbols in the above equation have the following meaning:\n\n{p_{(H_2O)}} is the partial pressure of water vapor in the gas mixture;\n\n{p^*_{(H_2O)}} is the saturated vapor pressure of water at the temperature of the gas mixture; and\n\nRH_{&#92;,_&#92;,} is the relative humidity of the gas mixture being considered. \n\nYou could get more information from the link below...

Open up everything can be opened and let it sit under a fan for a day or so.  Sometimes they come back after everything drys. Mine did. Good luck.

to increase humidity so nothing dries out\n\nlike a cigar humidor

Water molecules in the air are continually shifting from liquid to vapor. As the Brownian motion and swirling air currents or breezes are moving them around. \n   Thus some of the water at 100 % humidity will be condensing on cooler surfaces while others are evaporating from warmer surfaces eg. your skin.\n   P.S. Your question didn't say but I hope you are standing under a umbrella or something cause at 100% humidity it's likely to be raining. \n\n  Also humidity is relative to air temperature so if the sun is shining during this sun shower, the true quantity of vapor in the air may continue to rise, while humidity actually falls.\n  Nature is truly a conundrum, and even the best super computers, and weather models fail to predict what the weather will do.\n So don't strain your brain.

Spray your sweater with Static Guard or increase the humidity in your environment.

the correct instrument for relative humidity is a hygrometer. a humidifier humidifies the air. a thermometer measures the temperature. a barometer measures the relative air pressure.

use a fan and circulate air by opening windows.
