Strong but unseen, gravity affects all movements throughout life. On land, the human being uses data points of resistance against which the body is able to thrust. When placed in water, such data points are removed and balance must be related to a new data point - the centre of buoyancy of the body. Important considerations for activity in water The following facts must be considered and understood if exercise in water is to be successful 1.Shape and density are critical factors in responding to immersion in water 2.There are two planes of rotation in water. 3.There are two extremes of posture of the human being in water. Shape and density Normal Water reacts to the shape and density of any object placed in it, and floats the object according to these factors. This also applies to the human being when in water, and the variations in shape and density. The less elaborate the design, the more useful it becomes for both therapy and recreation, and any equipment required should be both simple and easily removed from the pool. There is, then, little or no need for elaborate pool design or equipment when taking disabled children into water. Although an increasing number of pools are being built, those wishing to give the experience of water activity and traditional hydrotherapy to the underprivileged may use many older facilities satisfactorily. The following points to be considered about the environment are not intended to be a manual of hydrotherapy spa or pool design, but rather some factors for consideration when commencing hydrotherapy. 1. Water and air temperatures. 2. Water depth of pool, expanse of surface of water 3. Height of poolside above the water. 4. Noise factors. 5. Lighting Water and air temperatures When taking disabled children into water, the temperature of the water and air should be between 30°C and 34°C (86°F and 93°F). This is not as warm as the average temperature of hydrotherapy pools, which is 35.5°-36.6°C (96°-98°F). If the water is too warm, it proves exhausting and uncomfortable. However, if it is too cold, inhibition of movement may occur, and since movement can also be diminished by the child's disability, heat loss to the water becomes a problem. Skin temperature is normally 33.5°C (92°-93°F) and water temperature above this will feel warm to hot, and below it cool to cold. Air temperature should be slightly lower than that of the water to allow gentle cooling. The rate of cooling of a body in a given time is proportional to the difference in temperature between the body and its surroundings. The greater the difference in temperature the greater will be the rate of cooling. This is Newton's Law of cooling. Humidity is another factor to be considered. If the humidity and atmospheric temperature are high, the body cannot lose heat by conduction, convection, and radiation. If the body has difficulty in losing heat, it can be very uncomfortable for everyone involved. Proper climate and environmental control is an important factor in any hydrotherapy program.
