Hot tubs and spas are a fantastic way of getting water therapy that is very much required to refresh the body and the mind. The physical properties of water make it a very useful and helpful medium for treating the muscles, back and neck pain. Water is used for providing hydrotherapy and hydro massage which is related to viscosity and buoyancy effect of water. The buoyancy or floatation effect of the water helps in counter acting the gravity to a limited extent by providing support to the body weight. This can be controlled with use of different massage seats inside the hot tub. This buoyancy effect supports simple workouts like flexing and stretching inside the hot tub. The viscosity of the water in the hot tub provides the necessary friction and with pressure from air jets relieves the pains and aches and strengthens the muscles, while lowering the risk of getting injured due to balance loss. The hydrostatic pressure improves the lung and heart function and also aids in enhancing the blood flow. Also hot tubs and spas have high pressure jets fixed to it by giving a massage similar to the itching and stinging type which may not penetrate deeply to allow the person get the most needed relief from pain. These jets can be changed in the hot tubs and spas according to the therapy needs. All the above properties when joined together allows to treat pains and aches due to the reduction in weight of the body placed in the stretched position in the hot tub due to buoyancy effect. Take for example, people suffering from osteoarthritis of the shoulder and neck can practice shoulder rolls and arm circles in the water by improving the strength and range of motion. They will not experience pain due to the warmth of the hot tub spa, due to water providing the necessary resistance and support through buoyancy effect. Need for hot tub spa accessories and supplies: Specific hot tub accessories and supplies are very much needed for the hygienic and proper functioning of a home spa. When people think of hot tubs and home spas they just think of a tub made of wood filled with hot water, but on the contrary it is a very complex piece of machinery, known to only people familiar with hot tubs or those who are trying to purchase by doing some research on it. For the safety and hygienic conditions of the hot tubs, it is very necessary to purchase all the spa essentials. Hot water tub spas should be purified continuously. Normally bromine and chlorine are added to the water to avoid bacteria and other micro organisms to grow in it. There are other supplies which play similar role of pH balancers, alkaline test kits, water test kits and other test strips which are used to determine the levels of particular compounds in water. Certain supplies like scum absorbers or calcium deposit removers are used to remove any calcium deposits accumulated in the hot tubs. Scum absorbers skim the water surface and help in the absorption of debris, dirt and other unwanted particles. These little resources if used consistently they will relieve the work load of filtering the water in the hot tub spas. Filters and catridges specially designed for filtering should be replaced very often.
