With winter comes the soft jumpers, early nights and, for some, the ever annoying sniffles. We all know someone who seems to fall sick every winter.

However, so far there has been no causal links between cold weather and getting the flu. The cold weather does increase the likelihood of falling sick, but it’s still all those same pesky germs that affect you year round that causes the flu.

The cold air does create situations that make you more susceptible, though.


The dropping temperature creates an environment that is more hospitable for viruses and they tend to linger in the air. This means that if you’re not taking care of yourself and your immune system, it increases the chances of these viruses attacking successfully as there is more of them.

Respiratory System

Cold, dry air also cuts down on the healthy mucous in your respiratory system. This leaves you more vulnerable to unpleasant microbials if you’re not keeping your nasal passages moist. One of the best ways to do this is to get a humidifier to avoid dry air in your home.

Staying Indoors

We all love curling up in the winter with a good book and cup of tea. Moreover, while that might be soothing for the soul, every other time you’re stuck inside, whether it’s in buildings or at the shops, you increase your chances of falling sick. This is because many buildings have dry heat and poor ventilation – which has been suggested to help transmission of diseases. Also, you’re stuck in a confined space with many, many other people, making the spread of germs easier.

Seasonal Allergies

When weather changes it also gives way for different pollens and allergens to permeate the air. So sometimes it might not be the cold that’s causing the sniffle but that you’re actually allergic to the pollens in the air.

Experts have said that taking supplements like vitamin C do not always prevent you from falling sick. Instead, when it comes to colder seasons, human behavior better determines this outcome. So always make sure to practice good hygiene.  Always clean your hands and use anti-bacterial soap— especially after you’ve just been out and before touching you face. Good sleep patterns and moderate levels of exercise will also help.

Essentially, the same advice you use all-year round just be extra diligent about it. And be aware of what’s causing your sniffles — flu germs or allergy to pollens in the air.
