But it\u2019s also a time when illnesses seem to increase: colds, flu, and other respiratory infections are more common. It\u2019s common to wonder why we get sick more often at this time of year. While several factors are at play, there are environmental, behavioral, and biological causes that explain this trend.<\/p>\n<p data-mce-fragment=\"1\"><img decoding=\"async\" data-image=\"efju72s6uknw\" src=\"\/wp-content\/uploads\/shopify_wysiwyg\/Banniere_600x600.jpg\" style=\"float: none;\"\/><\/p>\n<p><strong>Temperature changes and their impact on our body<\/strong><\/p>\n<p>One of the main reasons we get sick more often in the fall has to do with temperature fluctuations. As summer ends and temperatures begin to drop, our bodies need to adjust. This transition process can temporarily weaken our immune system, making it more susceptible to infections. For example, going from a warm environment to a cold one or vice versa can stress the body. This sudden change in temperature can also affect the lining of our noses, making it harder for them to filter viruses before they enter our airways.\u00a0<\/p>\n<p><strong>Proximity and spread of viruses<\/strong><\/p>\n<p>Fall also marks the return to indoor activities. After summer, when we spent more time outdoors, we find ourselves frequenting closed spaces: schools, offices, public transport, shopping centres. This return indoors encourages proximity and increases the chances of virus transmission. The viruses responsible for colds and flu, in particular, spread more easily in closed environments where air circulates less and where individuals are in close contact.<strong>\u00a0<\/strong><\/p>\n<p><strong>The impact of seasonal habits<\/strong><\/p>\n<p>With the arrival of autumn, our habits change, and some of these changes also contribute to a greater susceptibility to diseases. For example, the return to school and work brings groups of people from different regions into contact, which promotes the spread of viruses that were not present in other geographical areas. In addition, the stress of returning to work or school can weaken the immune system, making the body more vulnerable to infections.<\/p>\n<p>Our eating habits can also change at this time. After summer, which is often synonymous with light meals rich in fresh fruits and vegetables, fall sometimes leads us to consume heavier foods, less rich in essential nutrients, which can affect our overall health.\u00a0<\/p>\n<p><strong>Less natural light and its effect on the immune system<\/strong><\/p>\n<p>In the fall, the days get shorter and we get less natural light. This decrease in brightness has direct consequences on our body, particularly on the production of vitamin D. This vitamin, which plays an essential role in the proper functioning of the immune system, is mainly synthesized by our skin during exposure to the sun. When we spend less time outside and the intensity of UV rays decreases, our production of vitamin D drops, making our immune system less efficient.<\/p>\n<p>It is also strongly recommended to take a vitamin D3 supplement all year round, especially during the colder and less sunny seasons.<\/p>\n<p>Land Art is your ally to achieve this by now offering a complete range of Vitamin D3, including 5 formulas, from one for babies to a new 100% vegan option, suitable for all members of your family regardless of age. We invite you to visit the complete page on our range of certified organic vitamin D3 to find which one would be the most appropriate for you.<\/p>\n<h3 style=\"text-align: center;\"><span style=\"color: #b96321;\"><a href=\"https:\/\/en.landart.ca\/pages\/la-premiere-gamme-de-vitamines-d3-liquides-certifiees-biologiques\" style=\"color: #b96321;\" target=\"_blank\"><b><i>CONSULT THE PAGE<\/i><\/b><\/a><\/span><\/h3>\n<p data-mce-fragment=\"1\"><strong data-mce-fragment=\"1\">\u00a0<a href=\"https:\/\/en.landart.ca\/pages\/la-premiere-gamme-de-vitamines-d3-liquides-certifiees-biologiques\" rel=\"noopener noreferrer\" target=\"_blank\"><img decoding=\"async\" data-image=\"y6528yclpiwa\" data-mce-fragment=\"1\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2181\/9183\/files\/D3_600x600.jpg?v=1727894258\" src=\"\/wp-content\/uploads\/shopify_wysiwyg\/D3_600x600.jpg\"\/><\/a><\/strong><\/p>\n<p>Fall is a time of transition, both for nature and for our bodies.
