Humans have the capability to withstand large variations in environmental temperatures, while relatively small increases in internal temperature (i.e. as little of ~3 °C) can lead to injury and even death. This study evaluated the effects of ambient temperature on autonomic sympathetic variable in medical students. In the present study a group of having 100 medical students between age 18-25 years of either sex were studied in the morning hours in peak winter season (temperature 2-10 degree Celsius) and peak summer season(temperature 40-48 degree Celsius) to see the effects of ambient temperature on autonomic function tests. This study was conducted in the department of physiology S.P.Medical College, Bikaner (Rajasthan).Sympathetic non invasive autonomic function test were performed that is hand grip test and postural change test including resting blood pressure. The results were statistically analysed by applying paired “t” test. On comparison sympathetic function test like orthostatic variation of blood pressure and hand grip test were statistically significantly lower (p<0.05). The present study shows that no significant correlation in anthropometric parameter changes in ambient temperature in boys and girls.
