Against heat: Bring cool air into the apartment
In the summer, the air in the apartment with us, if it is hot longer or, as is now, hot and humid. Unfortunately, the cool air does not manage to cool down even at night: ground floor apartment, no breeze, no draft.
Then, in the cool morning hours, I put the fan out on the windowsill (clear that I'm taking a safe stand) with the back out. Set the highest level and let the cool air flow from outside into the apartment. I checked it with the thermometer - that brings real cooling, up to 4 degrees. In addition, everything smells wonderfully of basil, which stands on the windowsill with us.
