Position fan facing out to exhaust hot air

To cool a room effectively without air conditioning, position a fan facing an open window to exhaust hot air, while another open window elsewhere draws in fresh air. For optimal cooling, place the fan facing outwards from an open window, and open another window further away to create airflow. Avoid placing a wet cloth in front of the fan, as it reduces airflow. Additional tips include placing frozen water bottles in front of the fan for cooler air and ensuring adequate hydration. This advice is especially relevant during heatwaves, where fan placement is crucial.
