Hot weather can cause serious health risks if you do not protect yourself from the heat. Young children, elderly people and those with long-term illnesses are particularly at risk. Espoo Region Environmental Health Services wants to remind everybody to prepare for hot weather in advance.
One way to be prepared is to try 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.
