Summary Forty fullterm newborn infants, after uncomplicated pregnancies, uneventful labor and spontaneous delivery, were studied. The heart rate, systolic blood pressure (according to Ashworth & Neli‐gan) and body temperature were recorded 15 and 30 min and 1, 2 and 3 hours after birth, as well as on the morning of each of the following six days. A significant decrease in systolic blood pressure, heart rate and body temperature occurs during the first hours of life. The drop in body temperature and heart rate is most rapid during the first period of observation between 15 and 30 min of life, but the main drop in blood pressure occurs between 30 and 60 min after delivery. The decrease in blood pressure cannot be prevented by maintaining a stable body temperature in the infant. From the second to the seventh day, the temperature is relatively level, while the blood pressure and heart rate rise significantly.
