Water isn’t just effective at keeping our hands clean. Drinking enough water to stay well hydrated also has a positive effect on the immune system. If we’re already sick, the body needs plenty of fluids to make sure the electrolyte balance of salts and sugars is kept in check. Otherwise we can quickly become dehydrated and lethargic.
But to prevent getting sick in the first place, it’s also important to stay hydrated. Like you’ll see in the humidifier section below, the nasal cavity relies on moisture to help prevent us breathing in nasty pathogenic bacteria and viruses that can cause us to become ill. The more hydrated we are, the better our nasal cavity at staying defensive against bugs.
Also, water keeps our kidneys functioning well. The more water we drink, the more toxins our kidneys are flushing out in our urine, meaning less work that our immune system needs to do to defend against these toxins. Water also helps the body produce lymph fluid, which is part of the immune system responsible for getting rid of toxins. Green tea is also excellent at keeping us hydrated and is packed with immune loving antioxidants.
