The summer is coming soon to the Northern Hemisphere. How do you plan to combat the heat? I live in a regular apartment without air conditioning, and installing a full-scale system is not an option. I wonder what my options are, and how other people are planning to deal with the issue.
If you have a roof, you can put a sprinkler on it and spray water with a tap timer. Just enough to wet it, so that the water can evaporate and cool the roof.
If you have windows facing the sun, get blockout curtains and close them before the sun hits them.
If your front door has a window, get an expanding shower rail and hang a blockout curtain.
If you have internal doors, keep them closed.
Wear clothes made from natural fibres.
Drink extra water.
Move slower.
Eat cold meals, like salads, rather than cooked meals that heat up your home.
Install a ceiling fan and keep the air moving.
When the sun is off a window, open it to encourage ventilation.
Keep air moving at night.
Put a thin cover on your bed.
Have cold showers.
