What is the optimum air humidity level for humans?

Answer 1

According to Lennox Industries, "National studies indicate a humidity level between 33 and 50 percent for optimum health and comfort"

Humidity (grains of moisture in a volume of air) is always noted in terms of relative humidity (RH) as humidity levels are relative to air temperature. Warm air can hold much more moisture than cold air. In the winter, the air tends to be dryer and moisture must be added to it to bring humidity levels up to a comfortable level. Moist air is much better for comfort by alleviating static electricity buildup, dry and irritable sinus and lung conditions, and moisture also makes your furnace work better as the moisture maintains higher sensible heat levels. You can actually reduce the temperature at which you heat and still feel just as warm.

In the summer, the opposite is usually true. Summer air tends to be more moist and this moisture must be removed or reduced to acheive better comfort levels. Fortunately, the standard split system air conditioner removes moisture as the warm air is passed over an evaporator coil where condensation occurs and is drained off.

Here is a good example of relative humidity. Get up in the morning when the dew is on the grass. The air near the ground heas reached it's dewpoint, the temperature where the air can hold no more moisture and is saturated so condensation occurs. The humidity is very high. As the sun warms the air, the condensation evaporates and the relative humidity level drops as the warmer air can hold more water. Same amount of grains of water per a volume of air but the air can hold more grains as the temperature rises.

Answer 2

The relative humidity varies rather throughout the time of the day being optimal around first mild and lowest mid afternoon. Temperature performs a function in convenience as properly as humidity. customarily that's cooler yet extra humid on the coast, warmer yet drier inland. extra human beings stay interior the tropical areas than the temperate or polar areas.perhaps this shows that heat humid climate is optimal for human beings.

Answer 3

Depends on the temperature. At 95 degrees F and 100% relative humidity it is unberably sticky and muggy for most people. On the other hand, at 50 degrees F and 100% relative humidity it will not be sticky and muggy.

Temperature is an important component that must be considered!

Answer 4

30-50%

Answer 5

50-60%
