Abstract SUMMARY ne of the major problems that facing population is exposure to extreme environmental temperature that is related to seasonal variation. In the past three decades the temperature on the earth surface has been increased due to global warming phenomena. One of the most causes of global warming is green house gas emission due to different human activities. Serious health problems are related to climatic change whether directly or indirectly. Extreme environmental temperature has an effect on human health by different mechanisms as exposure to extreme hot weather ma cause serious health problems (e.g. heat stroke). On the other hand extreme cold can lead to serious cardiovascular symptoms. Most vulnerable population to the negative effect of climatic change are women than men, elders than adults and people with illness. Cardiovascular disease is one of the leading causes of death in the world. Many cardiovascular responses are experienced by exposure to extreme environmental temperature. There is a global needs to study the effect of environmental temperature on human health and especially on the cardiovascular system. This is a community based study aimed to detect the influence of the surrounding environmental temperature on cardiac function. O Summary 77 Thirty of apparent healthy individuals submitted for longitudinal study along winter and Summer seasons. All subjects undergo specified inclusion and exclusion criteria. All subjects will be exposed to the following investigations at one of the coldest day in Winter (below 14 º C) and one the hottest day in Summer (above 34 º C): - Measurement of arterial blood pressure. - Local examination of heart. - Recording electrocardiograph (ECG). Results of the present study shows significant elevation in the blood pressure , associated with cold weather (percentage increase in MAP was 6.98% ,percentage increase in the systolic BP was 8.93% and percentage increase in diastolic BP was 6.23% ), on the other hand there were no significant change in the heart rate or other ECG findings. from our results we can conclude that in cold weather is associated with slight increase in the arterial blood pressure (systole and diastole) of apparently healthy individuals. And no significant change in the ECG findings |
