Took this technique I learned in prison to make it bearable during the heatwave:

  1. Wet the window with a sponge or rag.
  2. Put aluminium foil up against it. Shiny side out. Cut beforehand on angled windows like that or use the roll on vertical surfaces.
  3. To cover the overlap, just wet the foil already on there, but be careful not to pull it off at the edge. An overlapping strip will stick to the other ones.
  4. Use masking tape to cover any overlapping edges that come away, as well as the edges that have a hard time connecting to the windowsill.

This keeps out an incredible amount of heat; you can feel how hot the foil itself gets during the day, while keeping the inside nice and cool.

    You might also try a “swamp cooler” to cool down with:

    Grab a bucket and a fan, and pour ice water into the bucket. Put the fan on behind the bucket and sit in the cool breeze it makes. It’s like having your own little a/c unit.

    The one downside to this is that the evaporating water will eventually make the air humid and make it harder for your sweat to cool you down, but it works great in the short term.
