Abstract:

his article shows the survey results of 20 Antarctic expedition members' blood pressure and pulse rate in different seasons of a year. The statistical analysis indicate that during polar nights the systolic pressure was lower than the observed in other seasons, and it was at the lowest level of the year and the margin of the highest and lowest level was 6.94 mmHg. The diastolic pressure during polar days was higher than the value observed after the expedition members came back to homeland. The systolic pressure was getting higher from morning to night. The pulse rate value of residents in Antarctica was even lower than baseline, and during the polar nights it reached the bottom value of the year. The body temperature was higher than the basic value during the days in Antarctica, and the charging pattern during a day was quite similar to the systolic pressure. These results provide some physiological parameter of adaptation for winterer in Antarctica. They also provide the basal data to special natural environment.
