I love AC but I don't like the health problems that Come with AC.That's why I will choose ordinary fan. Although, AC is more convenient for humans,its health implication calls for worry. People that work in air conditioned environment can experience chronic headache and fatique.They can also experience constant mucous membrane irritation and breathing difficulties.This leaves you vulnerable to contracting cold,flu and other illnesses. Long hours spent under AC can cause your skin to start losing its moisture.If you don't constantly moisturize,you may begin to suffer from dry skin. AC can also enhance the effect of an illness you already have.AC increase the symptoms of low blood pressure, arthritis and neuritis People who spend long hours under AC are always intolerant of heat.This intolerable of hear has lead to increase in heat related deaths during heat waves. This are some reasons out of the numerous reasons I prefer ordinary fan to AC anytime..so before you spend on that AC,think of the consequences I stated above.
