One of the SIMPLEST ways to boost your immune system during cold and flu season is to hydrate, hydrate, hydrate! When dehydrated, your cells become less efficient at removing toxins AND the cells that form your skin, gut tract lining, and mucus membranes (e.g., lips and mouth) form tiny “micro-cracks”, which can allow even more water loss. These tiny openings can be points of entry for viruses and bacteria and are the easiest way for them to hijack your system. So, drink more water in the winter – don’t wait until you’re thirsty, make it a habit.
