If your home does not have air conditioning, there are simple ways to help keep it as cool as possible during the hot summer months. The number-one rule of thumb? Circulation, circulation, circulation. Since heat rises, put fans on the upper level of your house and open windows on the lower levels. For smaller homes or apartments, close windows near fans and open the windows that are farthest away. This simple trick will help maximize the airflow and keep the air moving as efficiently as possible. The effect will help wick away sweat from the skin and keep you cool.
