While usually dismissed as an "old wives' tale", Yale University scientists found that cooler temperatures can result in a slower immune response to non-beneficial bacteria and viruses that enter the body. They determined that in cold temperatures, immune cells were less likely to commit programmed "cell death" to prevent the spread of the virus to other cells.

However, even with cold weather taking some of the blame for a nasty cold or bout of the flu, it's still germs and compromised immune health that make you sick.

There isn't one foolproof way to stop germs from entering the body, but there are steps that you can take to strengthen your immune health.

With 70% of the immune system located in the gut, an optimal gut environment leads to strengthened immune health. And Gutbiome6 does just that, supporting the gut barrier by strengthening tight junctions.
