Diet and nutrition. You won't usually need to keep to any special diet. A healthy, low-fat, nutritious and balanced diet is important for everyone, but if you're on steroids it's particularly important because these can increase your appetite and cause weight gain. Try not to over eat, and cut down on fatty and sugary foods and others which are particularly high in calories.
If you start out with 95 degree F and a relative humidity of 25%, the swamp cooler can get you 75 degrees and 50% relative humidity. That humidity level is still pretty comfortable. If you start out with 95 degrees and 40% rel. humidity.
When you have 80% relative humidity in the morning the amount of moisture added by the swamp cooler is negligible. As the heat of the day arrives and the relative humidity falls, more moisture evaporates at the swamp cooler (subsequently lowing the air temperature). Again, 70F 80% relative humidity is comfortable. 95F 36% relative humidity is not (and they contain the same volume of water vapor).
