Hydration plays a critical role in a person's overall health especially when it comes to illness. Proper hydration helps the bodily fluids that carry immune cells throughout your body get to where they need to go to fight off infections.
Facts: Hydration & Illness
According to Abbott, the benefits of proper hydration include lowering fevers, lessening headaches, moisturizing membranes, and better use of nutrients.
Water regulates your body's core temperature. Mild fevers can help eliminate infection, but dehydration can make a high or long-lasting fever worse.
Because the brain is about 80 percent water, proper hydration can help lessen headache pain. Dehydration affects blood volume. If your brain isn't getting the oxygen and nutrients it needs, the result can be dizziness and headaches.
Hydration keeps the mucous membranes in your nose and mouth moist so they can effectively expel bacteria and viruses when you're coughing, sneezing, and breathing. Moisture also helps heal broken membranes so additional bacteria don't get into your body.
Your gastrointestinal tract can better absorb and use nutrients from food when there's enough water in your system. When essential nutrients are available to the cells in your body, it can do a better job recovering from illness.
Staying hydrated also keeps the urine flowing, which reduces the number of bacteria in the urinary tract and lessens your chances of a urinary tract infection.
While staying well hydrated may not prevent illness, it does help your body to fight infections. Ensure you are drinking the recommended amount of water each day to keep you hydrated and healthy.
