Wondering, "Does your heart stop when you sneeze?" It's a common myth, but the truth is, sneezing doesn’t actually cause your heart to stop. What happens is that sneezing can momentarily alter your heart rate and blood pressure due to the sudden rush of air and muscle contractions. This temporary change can feel like a pause, but your heart continues to beat normally. Understanding this can help dispel the myth and ease any concerns about your heart health.
