It's in every living cell, tissue and organ, and it's second only to oxygen as the thing we need most to survive—pure, clean water. We can’t live without it, and we can't live well without enough of it. We are constantly in need of water as we lose water with every breath and every activity of the body. We are especially at risk for dehydration when we exercise or we are ill— this is when dehydration, even mild dehydration, can take its toll, causing you to feel tired and drained of energy. Anyone may become dehydrated, but young children, older adults and people with chronic illnesses are most at risk. Dr. Julie Scarano, a doctor of chiropractic who is trained in prevention and wellness in addition to providing care for neuro musculo skeletal conditions such as neck or back pain, for which chiropractors are most well-known believes it's better to prevent dehydration than to treat it. She also reminds you that the 23 inter vertebral discs in your spine have high water content and that dehydration can be associated with spinal pain. We can survive with or without water but one cannot survive without oxygen it is the only important thing to survive.
