People often complain of achy joints or migraine headaches as the weather changes, but is there any truth to it? Sudden changes in the weather can create unexpected hazards like slip and falls in a snow storm or sun stroke on a hot humid day. There is evidence that high temperatures with high humidity, especially in the very young and old, can trigger respiratory conditions causing shortness of breath and wheezing. Science has found that it is actually quick changes in more than one weather element that can affect mood, behaviour, heart attacks, strokes and even joint swelling.

Weather Connections to Health

Migraines – There is a seven times increase of migraines when the temperature increases by 10 degrees Celsius (18 degrees Fahrenheit) and is combined with a falling (low) pressure system.

Heart Attacks – Cold winter weather constricts blood vessels and a drop of 1 degree Celsius (1.8 degrees Fahrenheit) corresponds with an additional 200 heat attacks. No snow shovelling if you have heart disease.

Swollen Achy Joints – A drop in barometric pressure which often happens in cold weather seems to cause soft tissues to expand slightly increasing pain and sensitivity in joint movement.

Sleep Apnea – If you are not using a CPAP machine, a drop in barometric pressure can lead to worsening sleep apnea. The CPAP machines actually manage your air way pressure to keep the pressure consistent.

Environmental Allergies – Pollen counts are higher after a rain storm, a winter thaw and a windy day.

MYTH BUSTER: Changes in the weather, colder temperatures, higher humidity, wind and rain have not been associated with a weakened immune system or vulnerability to colds and viruses.

The 5 Elements of Weather are Temperature, Wind, Pressure, Precipitation and Cloudiness
