#Thyroid #hormones ensure a steady pulse and help the #bloodflow smoothly throughout the body by #relaxing the #bloodvessels. A well-functioning thyroid can contribute to lower, healthy #bloodpressure, a #strongerheart, and the ability to pump blood faster when needed, during #exercise or in stressful situations. The thyroid also helps keep #cholesterol levels in check. An underperforming thyroid, one that doesn't produce enough #T3 and #T4, can lead to fluid build-up around the heart.
