There exists a common belief that soaking in natural hot springs has significant health benefits. For example, Hotelexecutive.com claims that:
So What Exactly Can Soaking in Natural Hot Springs Do?
1) Improve Circulation - Bicarbonate hot springs are thought to help with blood circulation, hypertension, nervous imbalances and atherosclerosis.
2) Treat Skin Infections - According to the website Alternative Doctor, bathing in sulfur-rich hot springs helps treat dry scalp and arthritic pain as well as internal problems such as menopausal symptoms and digestive disorders.
4) Detoxify - It is believed that bathing repeatedly in hot springs can help tone your autonomic nervous system and normalize your endocrine system, as well as release toxins in your body through sweating.
5) Boost Immune System - Some proponents believe that iron content in hot springs, along with other trace minerals, might help build your body's immune system, making it stronger and more able to fight infections.
This leads to two questions:
- Is there any scientific proof that soaking in hot spring water leads to the above mentioned health benefits?
- Assuming so, can the same effect be achieved by soaking in heated water from a non-spring source, such as a lake or an ocean?
