A Scientist's Guide To Life - Indoor Air Pollution

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.

IS IT SAFE TO RUN EVERY DAY, OR SHOULD I DITCH MY RUN STREAK TO SAVE MY KNEES?

A running streak, where you run every day without taking rest days, can be highly motivating and beneficial for overall fitness. Running is great cardiovascular exercise and isn't to be discouraged (and finding a routine with some consistency is great). Getting a bit of exercise as often as possible is also hugely beneficial for your mental health.

HOW CAN I TELL IF I'VE GOT HIGH CORTISOL LEVELS?

Cortisol is a hormone produced by glands in our bodies called the adrenal glands, which sit above the kidneys. It plays a critical role in various bodily functions, including regulating metabolism, reducing inflammation and helping the body respond to stress. While essential for our health, chronic elevation of cortisol levels can lead to several issues.
