This invention is referred to the field of medicine, namely preventative treatment, and may be used as a means of synergetic minimization of negative impact of flights on human health (brain, stomach, lungs, blood vessels, heart etc.) with application of known substances and medicines with newly discovered pharmacological properties in new conditions. The ultimate technical solution of this invention would be synergetic minimization of negative impact of flying on human health without foot swelling, belching, jet-lag, tiredness and fatigue etc. The claimed technical result is achieved by the method of synergetic minimization of negative impact of air flights on human health, including consumption of substances that improve osmotic concentration of blood plasma, in the form of oral rehydration solution, split into two intakes as a minimum, first intake in the amount of at least 0.3 liters up to 1 liter before boarding and further during the flight from half an hour to 2 hours at least 0.3 liters to 1 liter and on as-needed basis.
