As we go from Summer to Autumn we may find, here in the UK, the weather is…lets say- indecisive. And with the seemingly random highs and lows in temperature you may see a rise in illnesses like the common cold.
So can a sudden change in climate be the reason for the sniffles?
Yes and no- they don’t cause a cold or flu themselves, however, they potentially could leave us susceptible to viruses. These changes we see in the climate are challenging our immune system and our musculoskeletal system. Our bodies are used to one climate, so when that suddenly changes our bodies take a little time to adapt- it is during this time of adaptation that a sneaky virus or infection can make its way in.
Cold, dry air is where viruses thrive
As the air becomes increasingly colder and drier in the autumn this means any viruses that come into contact with the body have an easier time of multiplying.
We also are suddenly faced with the challenge of trying to dress for varying temperatures throughout the day. Wearing a thick jumper in the morning chill may then feel like a bad choice as the temperatures rise in the middle of the day. However, if we are caught in the colder parts of the day while not wearing enough clothing to keep us warm can trigger infections of the upper respiratory tract. Try to remember to add light layers for those colder times of the day, that you can then take off when it gets warmer.
Heating and air conditioner
With fluctuating temperatures you may also find you are constantly switching between heating and air conditioning to help regulate your own temperature. This, however, will be dehumidifying the air you are breathing. This can be very drying to your throat which can, in turn, lead to irritation and soreness. If air-conditioners or heaters have filters that have not been changed this can mean they are most likely blowing out dehumidified air filled with pollen, dust, mold and midlew- a good cocktail for sinus and throat issues.
Immune system struggles
In theory the drier air also impairs the immune systems ability to fight any viruses that do come about. This is because the cold air may cause the blood vessels to constrict (perfectly normal just sounds scary) which may be making it harder for white blood cells to reach the mucus membrane in order to start attacking the virus.
Spending more time indoors and the days becoming shorter also mean we are naturally not getting as much vitamin D, a vitamin that helps to keep our immune system in order.
So keep a good eye on the weather and be sure to have those layers handy when leaving the house and make sure you are looking after yourself as best you can to make sure you are able to fight off anything that may be going around.
