Salt Water

Salt Water Hot Tubs have some unique and beneficial characteristics over soaking in strictly chlorinated water:

Natural Water Sanitation
Salt water has a natural sanitizing effect that fresh water does not. The sanitizing effect of salt means that a salt water hot tub needs less chlorine for disinfection than a fresh water tub. Less chlorine means fewer irritations to the skin and eyes. With fewer chemicals, a salt water hot tub also has a more natural smell.

Reduced Swelling
The combination of heat and salt water can be an effective way to treat swelling and edema, notes the National Strength and Conditioning Association. The hot water opens pores while the salty water draws fluid out of the skin. Salt water hot tubs can be used to reduce painful swelling from overexertion and exercise.

Tension Relief
Salt water hot tubs, especially ones with whirlpool capabilities can be used to release both physical and psychological tension. Hot water helps relieve muscle tightness while the water jets can massage and further loosen muscles. While hot tubs are often used by athletes for their restorative effect on muscles, everyone can use them for relaxation.

Healthy Skin
One of the disadvantages of heavily chlorinated, fresh water hot tubs is their drying effect on skin. Salt water by contrast, has a softening effect on skin. Salt is a common ingredient in many skin care products.

Joint Pain Relief
According to the Arthritis Foundation, heat therapy such as hot tubs can be used to relieve joint pain. In addition to the pain relief from the heat, the water provides an almost weightless environment that relieves stress and pressure on joints.
