High heat changes how your blood flows. Is your heart working double time? ☀️📈

As we head into the final days of June, the Central Valley heat is in full swing. At CCVMG, we want you to understand the physics of your cardiovascular system during a heatwave.

When it's hot, your blood vessels dilate to push heat away from your organs. This drop in systemic vascular resistance requires your heart rate to jump and your heart muscle to pump much faster to maintain safe blood pressure. If you are already managing a valve issue, irregular rhythms, or heart failure, this "summer fluid shift" places significant, physical strain on your body.

Stay inside during peak hours this week, and keep your heart's workload safe.
