From what I’ve been able to gather from the experts, the answer to this question is actually pretty simple: When the air outside is cooler than the air inside — like at dawn, dusk and overnight — keep the windows open to cool your house off. And when the air outside is warmer than the air inside — like at midday — keep them shut.

To my surprise, I found that many times when the outside air felt cooler than the air inside, the reverse was actually the case — sometimes significantly so. Indeed, at many times when I’d normally have opened the windows to let in the breeze, I discovered the outside air was actually three or four degrees (Celsius) hotter than it was inside.
Based on that new information, I’ve found myself keeping the windows shut for much longer during the day than I did in the past — closing the windows much earlier in the morning and opening them much later in the afternoon. And it’s made a real difference. At the end of the day on hot days now, I find the inside our house much more comfortable and at least a couple degrees cooler on the thermostat.

So what accounts for this discrepancy between how the air feels and its actual temperature? My guess: Wind. As everyone knows, even a small breeze can make the air feel notably cooler. And, especially in Vancouver, there’s often a nice breeze coming in off the ocean.
After two summers of experimenting, I am a firm believer in closing windows and blinds to keep the house cool when it is hot outside. But many people will resist. They can’t tolerate closed windows and blinds when it’s a beautiful sunny day. - See more at: http://www.timescolonist.com/opinion/to-stay-cool-leave-house-windows-closed-or-open-1.2179996#sthash.oWhODQaB.dpuf

Leaving windows open to reduce humidity is not always good advice but it is an interesting topic.
https://www.quora.com/If-you-have-high-humidity-in-your-home-people-advise-to-open-the-window-to-keep-it-ventilated-How-does-this-help-when-the-humidity-outside-is-higher-than-the-humidity-inside-my-house
We are not actually discussing total moisture content of the air in grains. We are discussing relative humidity. This means the percentage of humidity in comparison to the maximum amount of moisture the air can hold.
Warmer air can hold more moisture than cool air, therefore the colder the air the higher the relative humidity will be of the grains of moisture remain constant.
Think of it in the same way as how tea can hold more sugar when warm than when cool.
In many cases the relative humidity may be high inside because of internal moisture gains (showers, cooking, house plants) combined with an overly cool indoor environment.
people will often think the humidity outside is much higher than it actually is. The truth is that you will generally see consistently highest outdoor relative humidity during cooler, Rainier times.
The best things you can do to reduce indoor humidity are -
Reduce internal moisture loads by utilizing good bath and kitchen ventilation during showing and range use.
Keep doors and windows closed during the early morning and any time it is rainy
Open doors and windows when it is dry outside (no rain, no dew in the morning)
Use supplementary dehumidification
Ensure that your air ducts are well sealed. Leaky ducts can cause act to create low and high pressure zones in the home and atomic / crawl space which may act as a moisture driver.
Make sure your a/c is working properly and set up as best it can be to provide optimum dehumidification (but that is a different and even longer answer)

flip the pillow
lukewarm water bath
spray water to yoru body
dip your feet or wrist to cold water
Hot air rises
open door
blower fan just behind you
exhaust fan to get rid of hot air from your house if it is hotter than outside.

You should remember that even mild air movement of 1 mph can make you feel three or four degrees cooler.
Shades, drapes, or blinds
Install white window shades, drapes, or blinds to reflect heat away from the house. Close blinds, shades and draperies facing the sun (east-facing windows in the morning and west-facing windows in the afternoon) to keep the sun’s heat out and help fans or air conditioners cool more efficiently. Always remember that the best way to keep your home cool is to keep the heat out.
Deciduous trees planted on the south and west sides will keep your house cool in the summer and allow the sunlight to warm the house during the winter. For example just three trees, properly placed around a house, can save between $100 and $250 annually in cooling and heating costs, and daytime air temperatures can be 3 degrees to 6 degrees cooler in tree-shaded neighborhoods.
Humidity makes room air feel warmer, so reduce indoor humidity. Minimize mid-day washing and drying clothes, showering, and cooking. And when you must do these things, turn on ventilating fans to help extract warm, moist air.
Avoid landscaping with lots of unshaded rock, cement, or asphalt on the south or west sides because it increases the temperature around the house and radiates heat to the house after the sun has set.
Cotton absorbs sweat but nylon things do not. Thats why cotton is suggested in humid weather.
