Most of us know the routine. Winter arrives, temperatures drop, and suddenly half the office is sniffling.
You put on an extra layer, pull your hat down tight and hope it will be enough. Yet illness still seems to find its way in, almost no matter how well you bundle up. But it may be that for years we have been focusing on the wrong parts of the body.
Cold changes the body’s defenses
When temperatures fall, daily life shifts with them. We spend more time indoors, stay closer to one another and share the same air.
Cold weather also affects the body more directly. Research into viral behaviour shows that many respiratory viruses thrive better at lower temperatures than at normal body temperature.

That makes the body’s first lines of defence more important than many people realise.
One area in particular plays a key role, because it is often where viruses enter the body.
When the temperature there drops, the local immune response weakens and blood flow is reduced. This creates more favourable conditions for viruses to multiply.
It’s not just the head that gets cold
Surprisingly, the story does not end there. Studies from European cold research centres have shown that cooling the feet can influence the body’s overall resistance to illness.

Even though viruses do not enter through the feet, cooling in this area appears to trigger physiological reactions that make the body more vulnerable to infection.
Research suggests that if you want to reduce the risk of getting sick during the winter months, it helps to focus on:
- keeping exposed parts of the body warm
- avoiding prolonged cold exposure to the feet
- combining warmth with good hand hygiene
Small changes can matter
No one can fully protect themselves against viruses, especially during the colder months.
But by understanding how cold affects the body’s natural defences, it becomes possible to take more targeted precautions.

It is not only about comfort. It is also about giving the immune system the best possible conditions to do its job.
