Does Low Barometric Pressure Lower Blood Pressure?

I’m writing this post, as the barometric pressure has been low for a few days and my blood pressure has been as follows.

• Friday – 109/81/80
• Saturday – 120/47/78
• Sunday – 123/84/77
• Monday – 114/54/81
• Tuesday – 118/80/73
• Wednesday – 105/75/84
• Thursday – 108/81/74
• Friday – 107/56/70

The pressure had been going up and down all week, with two storms and quite a bit of rain.

So I asked Google AI the question in the title of this post and received this answer.

Yes, low barometric pressure can sometimes lower blood pressure, particularly systolic blood pressure, though the relationship can be complex and varies by individual and season. Studies have shown an inverse relationship, meaning as barometric pressure drops, blood pressure can also decrease. However, other factors can also influence this, and some research suggests a more complex “U-shaped” relationship where both very low and very high pressures may be associated with changes in blood pressure.

That’s fairly conclusive.

This paper on the National Library of Medicine, which was entitled Evaluation Of The Impact Of Atmospheric Pressure In Different Seasons On Blood Pressure In Patients With Arterial Hypertension, is referenced.
