TL;DR¹

• If not humid, wet clothing etc. helps. Any evaporating water
• Wind: either as ventilator or as draft. Unless it’s too hot
• “Flush at night” if night air is cooler

Let me count the websites:

• Wind

  • How can residents stay cool at home when they lack air conditioning? | Global Heat Health Information Network - really nice and full of common sense

    • when it is cooler than 35°C (95°F) opening windows on opposite sides of the building, then using an electric fan to pull cool air into the living space and a second fan to blow hot air out. This creates a cross-breeze.

  • Principles of Heating and Cooling | Department of Energy

    • As moisture leaves your skin pores, it carries a lot of heat with it, cooling your body. If a breeze (ventilation) passes over your skin, that moisture will evaporate more quickly, and you’ll be even cooler.

  • Theres’ a threshold, around 25-35C, when wind doesn’t help you anymore
