We sometimes use the phrase ‘under the weather’ when we’re feeling unwell. The origins of this are possibly from the days of travel on sailing ships – when there were too many ill sailors to record their names in the log, they had to be listed in the space reserved for the weather report; and then they would be sent below deck to shelter from the elements.

Britain is known for its wet and highly changeable weather, and these constant fluctuations can leave our bodies in a state of unbalance.

Temperature can have an effect on our health – for example hot weather can lead to a feeling of lethargy due to dehydration or heatstroke. Being in the cold for too long can cause an increase in blood pressure, leading to heart attacks, more pain in the joints caused by stiffness, and even pneumonia due to weaker immunity and infections being more prevalent.

As well as temperature, air pressure can cause us to become unwell. Some people get headaches or migraines when a thunder storm is imminent – which is possibly due to the drop in pressure in the air causing chemical and electrical changes in the brain.

This is also linked to a change in blood pressure, which can be a risk to people with heart disease. Lower barometric pressure can also cause swelling of joints, affecting those with arthritis, and people with diabetes may find it harder to control their blood-sugar balance.

High humidity can also bring on headaches, as well as a stronger feeling of thirst. A good solution is to drink lots of water to keep the body refreshed and hydrated.

Asthma sufferers may find their symptoms are worse on humid days, due to a higher number of spores in the air. Asthma can be exacerbated when there are sudden changes in temperature, or in cold, windy conditions – likely due to the moisture or particles in the air that irritate the lungs.

This also affects people with allergies, such as those who suffer from hayfever – especially people who are sensitive to mould spores, as these are more abundant in warm, dry weather.

Similarly, dampness can lead to respiratory illnesses due to the excess of moisture in the air, which can have a negative effect on the lungs.

The weather also has a psychological effect on our health – with too much cloud and not enough sunshine, gloomy days can lead to a gloomy mood. But even if it’s not sunny, it is still important to get some natural daylight and fresh air every day, as getting out has been found to be helpful for those who suffer with depression. So it’s not all negative!

The wonderful weather plays an important part in our daily lives and is the beauty of Mother Nature – where would we be without it?
