As we drift from lazy Summer days into those crisp Autumn mornings we begin to venture into the season of colds and flu. The common cold is a form of virus and they generally like cooler temperatures, which explains why we are more susceptible in the colder months.
And, whilst these particular viruses are more prevalent during this time, our bodies immune system can also go through some seasonal changes that can make it easier for the viruses to take a hold.
Seasonal Immunity
Research has shown that our immune system is of greater strength during the Summer months. So as the Summer wanes, this reduced UV light that can help fight infections alongside a change in our nasal immune system can contribute to this seasonal susceptibility.
The lack of sunlight also lowers our Vitamin D levels, an important player in our immune defence and those cold, dark days mean we spend more time cooped up inside together rather than in the fresh air. This proximity to others for longer periods of time during the Autumn and Winter is widely believed to be a large contributor to passing around these viruses.
There is a strong amount of evidence showing that the immune system, just like the weather, also goes through seasonal changes.
Food Cravings
Our natural food cravings at different times of the year can be an indicator of the nutritional demands our body needs during the seasons. That desire to eat heart warming foods during the Winter months, reflects seasonal growing, in addition to the vitamins and minerals our body is looking for during those months where the infection risk is higher.
Keep it local and keep it seasonal
This highlights the need for eating seasonally and locally. Seasonal foods, bought locally are often fresher, due to their fewer air miles and more nutrient dense as they’ve been grown in the correct season.
This type of seasonal, locally grown eating promotes a wider diversity of fruits and vegetables and allows us to be more creative with our foods.
Experimenting with different foods, cooking methods, spices and herbs all help to boost our immune system and foster a healthy microbiome.
