Effects of age on body temperature and blood pressure in cold environments.

摘要: Mean deep body temperature fell by 0.4 +/- 0.1 (SD) degrees C in five sedentary, clothed 63-70 year old men and four young adults after 2 h exposure still air at 6 (P less than 0.001). The mean increase systolic diastolic pressure was significantly greater 0.002) the older subjects (24 4 mmHg systolic, 13 diastolic) (14 7 3 C. A small rise blood occurred 12 C, but there no either group 15 association of variables is particularly marked between core changes There were appreciable cold-adaptive or thermoregulatory responses 7-10 days repeated to for each day. Blood elevation cold slower more men. These may provide a possible basis delineating low domestic limiting conditions.
