Increasing your heart rate makes it stronger. But drugs like cociane, meth and disorders like anxiety that increase your heart rate are bad for your hearts health. Shouldnt it make the heart stronger?
In: Biology
Uneducated theory here. When you exercise, you’re not only strengthening your heart, but your entire cardiovascular system.
When you rack up you’re just telling the heart to beat faster which the heart, or the rest of the cardiovascular system, is not necessarily well prepared for.
