Comfortable temperature

The human race went through most of its evolution in Africa without any perceived need for clothes. We are genetically programmed to feel more comfortable in warmer climes. It is in our nature to respond to warmth, and now that the days are getting longer, we are looking forward to them also heating up. The average temperature in Africa is 27°C, and a human being can feel comfortable at this temperature without clothes. 27 degrees Celsius is the perfect temperature for the skin. Once it starts to get a little cooler – round about the 22/23°C mark – we begin to feel the need for clothes. The whole thing is genetically predetermined and is influenced by daylight.
