GOOD TO KNOW
Atmospheric pressure
Recent studies demonstrate an influence of meteorological factors, such as atmospheric pressure, on blood pressure behaviour.

tors and clinical implications. Hypertens Res. 2015; 7:869–875.
Temperature
The relationship between blood pressure and outdoor temperature in a large study of older people - the Three Cities Study.
The study included nearly 9,000 patients aged 65 and older. Measurements were taken at different times of the year at different temperatures. The results
showed that in winter the systolic value was about 5 mmHg higher than in the summer months on average. Thus, this demonstrated that in winter 1/3 and
in summer only 1/4 of the measured persons should have been classified as hypertensives (patients with high blood pressure).
In people over 80 years of age, the effect of blood pressure variability may be increased in different weather conditions and outdoor temperature.
