Ok

I'm doing better. headache reduced to annoying from throbbing pain. drank some tea and now I'm sweating. must have a fever

for me best way to break a fever is an nice HOT soak in tub while drinking hot dr pepper and lemon.

do you understand dewpoint? I can never remember what it is, so know I don't understand it

with a little lemon that and a hot soak will make a hot flash seem mild

and sure breaks the fever.

Dew point temperature is never greater than the air temperature because relative humidity cannot exceed 100%. In technical terms, the dew point is the temperature at which the water vapor in a sample of air at constant barometric pressure condenses into liquid water at the same rate at which it evaporates


I thought I sort of did before finding this and now I am really confused LOL

Can someone explain dew point to me like I'm stupid?

I don't know why I'm having such a hard time getting my head around this idea. I know it has to do with the saturation of moisture in the air, and therefore the evaporation of sweat and your body's ability to cool itself. What I don't understand is the way in which it is measured by temperature. If the dew point is 66 degrees, does that mean that is the temperature at which the air can no longer hold moisture? if that is the case, then wouldn't a dew point of 46 degrees be worse because the air is saturated at a lower point? Obviously thats not true so I'm missing an important element of this. Help?

Imagine cooling a volume of air. Dew point is the temperature at which the first droplets of water appear. Here is another way to think about it. You are probably familiar with condensation on the outside of a glass of ice water. Imagine, instead of ice water, a series of water glasses at different temperatures. Dew point is the warmest temperature that would still produce condensation on the outside of the glass.

This effect occurs because warmer air can hold more moisture. For example air at 100F can hold 0.043 lbs of water per pound of air, while air at 50F can only hold 0.0077 lbs of water per pound of air. Suppose the air temperature was 100F and there was 0.0077 lbs of water per pound of air in the air. The dew point would be 50F because once the air was cooled to 50F it would be saturated and water would begin condensing.

In the above example, if there was more than 0.0077 lbs water/lb air then the dew point would be higher. Higher dew point represents higher humidity.

You may be wondering what this has to do with evaporation of sweat. For evaporation to occur there must be a difference in humidity. This is known as a driving force. The larger the driving force the faster the evaporation will occur. (same thing applies to cooling, e.g., an object will cool faster in the freezer than the refrigerator). Faster evaporation means more cooling.

I hope this helps.
