Key result
Short-term cold exposure significantly increased central aortic BP in hypertensive men (130/93 to 162/107 mmHg, P<0.001) and controls (114/81 to 142/91 mmHg, P<0.001).

Cold exposure was associated with higher central aortic BP; hypothesis-generating for seasonal CV risk in hypertension, needs prospective confirmation.
Observational (n=61)
Does short-term cold exposure increase central aortic blood pressure and cardiac workload in untreated hypertensive men?
p-value: p=<0.001
Short-term cold exposure significantly increases central aortic blood pressure and cardiac workload in both hypertensive and normotensive middle-aged men, potentially increasing the risk of adverse cardiovascular events in those with baseline hypertension.
Hintsala et al. (2013) conducted an observational in Hypertension (n=61). Short-term whole-body cold exposure vs. Baseline was evaluated on Central aortic blood pressure (p=<0.001). Short-term cold exposure significantly increased central aortic BP in hypertensive men (130/93 to 162/107 mmHg, P<0.001) and controls (114/81 to 142/91 mmHg, P<0.001).
