You might think that going outside in the cold makes you more likely to ‘catch a cold’. But in fact, colds and the flu spread much more easily inside. Let us explain …
How are colds and flu spread?
Both flu and the common cold are caused by viruses, which are spread through exposure to respiratory secretions (i.e. an infected person’s sneezes or coughs). The virus can be spread through the air, personal contact (such as a handshake), or by touching contaminated objects.
How long do cold viruses remain infectious?
As you can see, cold and flu viruses can hang around indoors for up to 24 hours – and people can shed huge numbers of cold / flu viruses into the air which can in turn settle onto surfaces:
Nature’s outdoors remedy - Hydroxyls
However, outside, you’re much less likely to catch these viruses. That’s because Hydroxyl Radicals, which occur naturally and abundantly in the air outside, kill all human pathogens on contact, including cold and flu viruses.
Hydroxyl Radicals are commonly known as ‘Nature’s Detergent’, and we think they are pretty amazing!
