Frequent travellers are exposed to radiation oxidative stress

15 December 2011


The fact is clear: We are living in the most toxic environment in history.  Our environment is heavily polluted with toxins – polluted air, water, pesticides in foods and drinks, carcinogenic substances in processed foods, heavy metals and not forgetting, radiation exposure from medical testing such as CT scan, mammography, and low frequency radiation from cell phones. These are described as underappreciated and underestimated in the 2008-2009 Annual Report by the President’s Cancer Panel of scientists, USA. The same report highlighted the growing body of research that shows how environmental factors are linked to genetic, immune and endocrine dysfunctions, leading to cancer and other diseases. Anand, et al. (2008, p.2098) reported that 95% of cancer cases have their roots in our environment and lifestyle.

Frequent travels and constant exposure to electromagnetic radiation that is generated by the increasing use of wired and wireless technologies (cell phones, wireless- LAN, wireless communication at home and office) increase oxidative stress in our body, which is associated with cancer and many degenerative diseases. According to Health Canada, for those who fly frequently, like business travellers and aircrew, the annual exposure to radiation is comparable with or exceeds that of radiation workers in ground-based industries. Even low exposures to radiation can start off chains of events that may lead to cancer many years later.

Besides measures to minimise exposure, one of the best ways is to consume herbs that are known to have protective effects against radiation. According to Jagetia (2007), some of the herbs shown to be protective are pegaga, galangal, holy basil and phyllanthus emblica (as in Phytolec™). The formulae tea Phytocel™ contains pegaga and basil.

Phyllanthus emblica is demonstrated to have protective effect upon radiation-induced chromosomal damage in both humans and experimental animals. (Singh, Sharma, Jindal, Soyal, & Goyal, 2006, p.129). One of the ways that this herb protects you is the prevention of depletion of glutathione (GSH), the most important antioxidant produced by your body. Depletion is often associated with increased risk of cancer, skin diseases, autoimmune disease, allergies etc.
