(NewsUSA) - As you get older, you depend on the simple things in life to help relieve stress -- the arms of a loved one, the comfort of your mattress, shower pressure and possibly a few too many Dove chocolates. But did you know your bathtub can be a source of much needed therapeutic benefits?

Hot baths offer many relaxing health advantages -- they're a natural detox because they increase your core temperature, dilate blood vessels, improve circulation and clear lymph nodes to stimulate the immune system. Since most Americans are also magnesium deficient, according to the National Academy of Sciences, adding magnesium-rich Epsom salt to a bath has further benefits: it reduces inflammation, improves insulin absorption, relieves stress, helps nerve function and plenty more.

In fact, some bathtubs are actually designed with different forms of therapy to target specific diseases and illnesses.

Chromotherapy relies on variable colors of light, which can have positive effects on mental well-being and relaxation. The aromatherapy component uses pellets of essential oils to aid in emotional and physical healing. The whirlpools, jets and air massages of the hydrotherapy, however, are the aspects that help the most with the following medical conditions:

* Arthritis

* Insomnia

* Diabetes

* Asthma

* Bronchitis

* Circulatory disease

* Rheumatism

* High blood pressure

* Hemorrhoids

* Fibrositis

* Lumbago

* Joint, muscle and nerve problems

Other common ailments are also eased by the extensive benefits of hydrotherapy, like stress, anxiety, headaches and lower back pain. The added pressure and stimulation of jets and bubble streams create a methodical massage for the entire body, all of which is completely adjustable.
