The mean and changes of systolic-diastolic blood pressure (blood pressure) in exposure to heat and different noise level and also simultaneous exposure to noise and heat. (a) The changes of systolic blood pressure in exposure to heat (40°C and 40% of humidity), (b) the changes of systolic blood pressure in exposure to different levels of noise, (c) the changes of systolic blood pressure in exposure to different levels of noise and heat simultaneously, (d) the changes of diastolic blood pressure in exposure to different levels of noise, (e) the changes of diastolic blood pressure in exposure to different levels of noise and heat
