Hello#When i visit hot countries I have an allergic reaction to the heat.  Noit sunshine, but the heat.  I dont break out in a prickly heat rash more of a bluish tinge.  The medical surgery in that country then administers a steroid injection.What can I do to prevent this happening before I go on holiday.  It has been suggested that I take beta carotene.  Is this a good idea?  Many thanks
Hollow, thanks for your question, Beta carotene, helps in some allergic conditions erythropoietin protoporphyriaon-inherited sun sensitivity, exercise induced asthma, sun burns in some cases, many doctors that it should be taken from natural source rather than supplements, raddish is good source, but you don't have allergy to direct sunlight, so I guess it won't help to that extent, you can try it if problem persist consult physician.
