[Effect of phytoncides on the dynamics of the cerebral circulation in flight controllers during their occupational activity].
In order to optimize the environment in which flight controllers normally work, volatile phytoncides of brandy mint, lavender, and anise were used. After their 20-day application the health condition of the flight controllers improved. By the end of the working hours they felt less tired. Besides, as shown by the rheoencephalographic data, their cerebral circulation showed no abnormalities. The examinations carried out at the end of the first shift and at a high occupational load, when no phytoncides were used, showed that the REG-wave amplitude decreased and tonic tension of cerebral vessels (alpha, alpha/T, alpha/beta) increased; these changes are typical of fatigue. When the biologically active substances were employed, the changes were of the opposite pattern: adequately increased mental capacity, reactions which included a diminished tension of the vascular wall and a moderately increased blood content of the vessels).
