Results Mean of systolic blood pressure in exposure & none exposure groups are 119. 34, 118. 06 mniHg with P = 0.196, mean of diastolic blood pressure in two groups are 78.66, 77 . 19 mmHg with P = 0.03 & mean of body temperature are 36.99 & 37°C with P = 0.079, the mean difference of HDL cholesterol and salt consumption between two groups with P = 0. 000 has been significant Conclusion Mean of blood pressure & body temperature are normal . . with regression analysis we found that cold exposure might be had some effect on diastolic blood pressure
