A Scientist's Guide To Life - Indoor Air Pollution
BBC Focus - Science & Technology
|July 2021
Cleaning products… candles… cookers… how much does indoor air pollution really affect us, and what can we do about it? Respiratory specialist Dr Jonathan Grigg explains all -
INDOOR AIR POLLUTION IS WIDESPREAD.
It takes many forms, from the tiny particles that are emitted when we cook or clean, to the spores released by mould when it’s damp, and the chemicals that are embedded in our furniture.
THE POSSIBLE IMPACT ON HEALTH IS CONCERNING.
Small particles that are inhaled can travel to the lungs and cause problems. Studies suggest that indoor air pollution is linked with an increased risk of certain respiratory problems, such as asthma and bronchitis.
PUT IT ON THE BACK BURNER.
We know that cooking releases particulates into the air, and that levels can remain elevated long after cooking is finished. Open a window when you cook and use the extractor fan if you have one. Put the pot on the back burner, where it will ventilate to the fan more efficiently. Keep the fan on for at least 10 minutes after cooking ends.
COOK WITH ELECTRICITY, IF YOU CAN.

DOES MY BRAIN LIVE A LITTLE IN THE PAST?
Yes, your brain does live a little in the past. It can't help it. The information it receives via your senses is always a little out of date. Whether it's light entering the retinas in your eyes, or sounds vibrating the hairs in your ears, it not only takes time for the data to arrive, but your brain then has to process it.
