The summer heat is over, that is, when your location is somewhere in the Northern Hemisphere. Can you withstand indoor temperatures of over 30°C (86°F) all day, for several or many days?

Even if you are inactive, the stifling heat takes a toll on you, leaving you feeling drained of energy and vitality. You might even experience summer fatigue or a feeling of lethargy. Those may be signs of what is called Seasonal Affective Disorder SAD, a kind of depression.

The impact of summerheat on people's health however can be much greater. It comes down to a combination of a person's exposure, sensitivity, and adaptivity. The Indoor Environment should be classified under the heading "Exposure". That is why good heat resilient and cooling facilities in buildings are becoming increasingly important.
