Use a Humidifier
Not something that’s common in lists of ways to support a healthy immune system, but one that is important – using a humidifier can help you to breathe easier and even help prevent you picking up bacteria and viruses that can affect the respiratory system.
Inside all of our noses, we have tiny hairs called cilia that work hard to trap all the dust, dirt and debris that we potentially breathe in each day. Amongst all of this also resides plenty of bacteria and viruses, determined to make it through our nasal passages and into our respiratory system where they can cause us to become ill.
So these hairs are essential for trapping these persistent bugs so that we can blow them into a tissue and throw them away. If the air we’re breathing is very dry, the cilia can’t do their job as efficiently, and will allow dust, dirt and bugs to pass down into the airways.
Whilst using a humidifier doesn’t technically directly benefit the immune system, it will keep the air more moist. This will allow the cilia to do their job properly to prevent infection, and in turn, give our immune system less work to do. Aim for a humidifier in all of your main rooms, especially your bedroom to help support good immunity.
