Scientific studies do have a use in today's world of "science". I just got back from a weekend of spa therapy. You know, the kind with hot and dry sauna's and the usual hot and cold pools. This place had hot, cool and cold pools. Useful for cycling from cold to hot pool temperatures. My goal was to do some body shock to create what are called heat shock proteins.About hormesis in general, I agree with this guy:
I know, he's a bit controversial ...
Some medieval aristocrats took small dose of arsenic, to survive poisoning attempts.
Apart from surviving a possible assasination, it surely not helped their health, or prolonged their life.
Any time cold or heat is elevated heat shock proteins are created. Heat shock protein - Wikipedia
"Heat shock proteins (HSP) are a family of proteins that are produced by cells in response to exposure to stressful conditions. They were first described in relation to heat shock, but are now known to also be expressed during other stresses including exposure to cold, UV light, and during wound healing or tissue remodeling. Many members of this group perform chaperone function by stabilizing new proteins to ensure correct folding or by helping to refold proteins that were damaged by the cell stress. This increase in expression is transcriptionally regulated. The dramatic upregulation of the heat shock proteins is a key part of the heat shock response and is induced primarily by heat shock factor (HSF). HSPs are found in virtually all living organisms, from bacteria to humans. "
Whenever you eat Indian food my guess is you are in your comfort zone and benefiting by that little intake of turmeric - perhaps more so than the Indians who eat it everyday. That is hormesis in action.
