To the best of our knowledge, a possible relation between smoking and heat injuries or heat
intolerance was never scientifically examined, although such a relation is logical according
to the observations that smoking has a thermogenic effect, decreases physical fitness and
affects the body's heat dissipation.16 healthy young male volunteers will participate in the
study, 8 smokers and 8 non-smokers. They will arrive to our lab four or six times. They will
perform VO2 test and heat tolerance test (HTT) in different conditions.
