How to prepare for hot weather

In recent years, Finland has had long periods of hot weather, and climate change only increases the likelihood of heatwaves. For this reason, it is important to prepare for hot weather in advance. On website of the Finnish Institute for Health and Welfare(external link, opens in a new window), you can find information on the health effects of hot weather and how to prepare for heatwaves.

How to reduce indoor temperatures

• Keep your windows closed during the day when outdoor air is warmer than indoor air.
• Cover the windows facing the sun with light blinds or curtains to block the sunlight. If a room tends to get too hot, you can apply a sun protection film on the window, install an awning outside the window or use plants to give some shade.
• Keep your windows open during the night to let cooler air in or increase mechanical ventilation.
• If necessary, use cooling air conditioners. Keep doors and windows closed.
• Switch off lights and electrical appliances when not being used because they also increase the temperature in your home.
• You can use a fan if the indoor temperature is below 35 degrees Celsius. Fans do not cool the air, so they do more harm than good at a higher temperature. If you use a fan at a higher temperature, it will increase the heat strain on your body. The fan can also dry out your skin, so remember to drink plenty of fluids.
