Comfortable Temperature For Humans
Satisfaction with the thermal environment is important because thermal conditions are potentially life threatening for humans if the core body temperature reaches conditions of hyperthermia above 37 5 38 3 c 99 5 100 9 f or hypothermia below 35 0 c 95 0 f.
Comfortable temperature for humans. What is the need to maintain a normal body temperature. The most comfortable temperature for humans is from 68 to 77 degrees fahrenheit. In order to create an environment with an effective comfort temperature of 70 f for every one degree fahrenheit that the average surface temperature is below 70 we will need to raise the air temperature 1 4 f to compensate for the radiant cooling of those cooler surfaces.
A decrease in temperature may make you restless and less attentive. So as humans perceive the rate of heat transfer from the body rather than temperature itself when the relative humidity is high we feel warmer. For infants the very elderly and those with significant health problems a minimum 20 c 68 f was recommended.
In fact the level of relative humidity directly affects the temperature ranges found to be acceptable by humans. An increase in temperature above the comfort level may make you tired and sleepy. The effect is similar to raising the temperature.
A human body s normal temperature also referred to as euthermia or normothermia is typically within the range of 97 7 to 99 5 f or 36 5 to 37 5 c. Buildings modify the conditions of the external environment and reduce the effort that the human body needs.
