Should I have windows open or closed in hot weather?

THE NHS has a whole range of ways and tips to beat the heat as temperatures are set to soar.

Here’s what you need to know about when to open your windows and when to keep them closed.

Should I have my windows closed in hot weather?

It really comes down to if the temperature outside is hotter or colder than inside.

The advice states: “Keep windows closed when it’s hotter outside than inside, but open them if the room gets too hot”.

Pale or thin curtains or blinds should be closed but should be kept open if they are dark-coloured or thick or you have metal blinds as they can make a room hotter.

Putting something reflective on the outside of the glass can bounce the heat away, keeping the room cool – similar to the screens that go on the windshield of your car.

Should I have my windows open at night?

The general advice is to keep windows open at night as it is cooler outside.

But for security reasons downstairs windows should be locked when you go out or go to bed.

It will also stop wild animals or neighbour’s pets creeping in who are looking for a cosy bed for the night.

How else can I keep my house cool?

The NHS has several tips for keeping your house and yourself cool during a scorching heatwave.

Keep windows that are exposed to the sun closed during the day, and open windows at night when the temperature has dropped

Keep rooms cool by using shades or reflective material outside the windows. If this is not possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter)

If possible, move into a cooler room, especially for sleeping

If you have concerns about an uncomfortably hot house that's affecting your health or someone else's, get medical advice.

It also recommends taking cool baths or showers and regularly splashing yourself with cool water.

You can also get help from the environmental health office at your local authority.

They can inspect a home for hazards to health, including excess heat.
