How does a sauna affect the body when you have a cold – What does the research say?

Can sauna bathing really help when you have a cold – or does it just make things worse?

Many swear by the heat of a sauna as a way to relieve symptoms, while others warn of the risks. In this post, we'll go over what you should consider when taking a sauna for a cold, which products can help – and what's just a myth.

What happens in your body when you take a bath when you have a cold?

When you sit in a sauna, your body temperature rises and blood circulation increases. This can help relieve nasal congestion, loosen stiff muscles, and provide a temporary sense of relief. But saunas aren't always the right choice—especially if you have a fever or an infection in your body.

Why can saunas help against colds?

  • The heat dilates the airways and can make it easier to breathe.
  • Sweating helps the body to clear out waste products.
  • Menthol crystals and eucalyptus oil enhance the effect by opening the nose and cooling the airways.
  • Regular sauna use can strengthen the immune system in the long term.
