The beneficial effects of spa bathing have been known for many years and those who have had the pleasure of using the spa have discovered a rejuvenating and revitalising experience. Most people have experienced the blissfully relaxing effects of a modern spa bath at their local swimming pool, leisure club or while staying at a quality hotel. Luxuriating in warm, bubbling water is an unrivalled way of unwinding and chasing away the stresses of daily life. Medical research has shown that various physiological changes are triggered by the temperature of the water and by the effects of weightlessness experienced in the spa.
