Cold weather makes you ill’ – is that really true?

‘Wrap up warm, otherwise you'll catch a cold!’

Everyone is probably familiar with this phrase – especially in autumn.

When temperatures drop, colds, coughs and sore throats become more common. So it's no wonder that many people believe that cold weather is to blame.

But is that really true?

The short answer is: No, cold weather itself does not make you ill.

Colds are caused by viruses – mainly rhinoviruses. However, cold weather can indirectly cause these viruses to spread more easily or weaken our immune system.

Why do we catch colds more often in winter?

In autumn and winter, we spend more time indoors. The air is drier, the mucous membranes in the nose and throat become more susceptible – and viruses have an easier time of it.

In addition, cold weather reduces blood flow to the mucous membranes. This causes the immune system to work a little slower, making it easier for pathogens to invade.

In other words, it is not the cold itself that makes us ill, but the circumstances it brings with it.

How to keep your immune system strong during the cold season

• Fresh air is good for you: Regularly ventilating rooms or taking short walks in the fresh air strengthens the circulation and moisturises the respiratory tract.
• Stay warm: Even if the cold does not directly make you ill, feeling cold can weaken the immune system. So it's better to dress warmly – Mum was at least half right.
• Drink enough fluids: Warm teas or water help to keep the mucous membranes moist.
• Restful sleep & exercise: Both provide lasting support for your immune system.

Conclusion:

Cold weather alone is not a pathogen – but it creates conditions in which viruses feel more comfortable.

With sufficient exercise, warmth and fluids, you can support your immune system to get through the cold season in good health.
