Your blood pressure is influenzed by hot to cold weather


Heart expert Dr. Padmanabhan has discovered that there is a connection between a drop in temperature during the day to your blood pressure (BP).  This may be because the arteries and veins tend to collapse with colder weather making it harder for blood to travel around the body.  This response to temperature changes may be under genetic control too. Which means some families may be more susceptible to temperature changes than others, so all people may not respond in the same way to weather changes. Those susceptible are 30% more likely to die from a deadly rise in BP than those who are not.

These heart experts realize that not many studies have correlated effect of weather on BP and recommend that physicians be aware of this. Quote

Temperature-sensitive subjects had significantly higher mortality (1.35 [95% confidence interval, 1.06–1.71]; P=0.01) and higher follow-up systolic blood pressure (1.85 [95% confidence interval, 0.24–3.46]; P=0.02) compared with temperature-nonsensitive subjects. Blood pressure response to temperature may be one of the underlying mechanisms that determine long-term blood pressure variability. Knowing a patient’s blood pressure response to weather can help reduce unnecessary antihypertensive treatment modification, which may in turn increase blood pressure variability and, thus, risk.

Unquote.
Sunshine plays a role in monitoring BP. Cloudy days raise BP.
