4. Wind Current
The cool air current blown by the ventilator, the air conditioning or the wind on your head, forehead or nape, especially if you’re sweaty or wet, may cause headaches. Don’t suppose your organism to too much artificial fresh air, as they can be the main source of headaches in hot days. Getting from a cool room into the middle of the hot weather outside will definitely give you a headache and you can prevent from this only by keeping a not-too-cold temperature in the room that you sit in before going outside.
