Therapy for vision, balance and walking all help with your daily activities. I have had all three and then some over the years. I also am of the mind that a good wholesome diet helps the body as does a good nights sleep. Walking or some sort of activity, even though it may seem 'dangerous' with the vertigo and balance disorder, still is needed to keep the body moving. We are not meant to sit or lie down all day. We need to move in one way or another. Movement if the key word here. We use our senses to negotiate our day/night. Our eyes help us navigate our way just as our ears help us hear and navigate our way around us and more. The nerves in our ears / brain do so much more in keeping us upright and moving. Our kidneys work in tandem with the electrolytes to keep our balance correct and our brains functioning as well as our gut working correctly. That's not the only organ working full time.
Water (H20) is the basis of all of this and when we don't have enough - trouble comes baring down on us. Our bodies need to have enough liquid in it to work proportionately right. If there is not enough, the liquids are squeezed out of one place and moved to another to have what the organs need. This is why we have muscle cramps and headaches. Activities, exercising and moving is done all day long....either actively or passively, at your desk, at the counter top in the Kitchen, in your bed, in the bathroom, in the swimming pool, anywhere you find yourself. Move your eyes, your shoulders, your hips, your head, hold onto the door handle, take a minute or two to stretch. move your eyes up and down and around. Have any bands around? Good - use them when you get out of bed in the morning for a number of stretches... to loosen up. Less aches and pains perhaps through out the day or they may not be noticed because you are incorporating these instant activities in your daily walk in life... Just a thought.
