Watching home and family who had doctor on today to talk about health questions during the winter. I noticed she promoted hand sanitizer.
Its well understood that it should be used rarely as it destroys the healthy bacteria on our hands they are there for our protection. Also she was right in saying that cold weather doesnt cause colds. Viruses do.
She failed to mention that keeping your homes, environments too warm can promote bacterial and viral growth. Its better to be in a cooler room and wear sweater or jacket as needed
