20 Cause of Petechiae and What You Need to Know About Them

18. Intense Weightlifting or Physical Exertion

Believe it or not, pushing your body too hard at the gym can lead to petechiae. During extreme exertion—like lifting heavy weights, performing max-effort squats, or holding your breath while straining—you can break small capillaries, especially in the face, neck, and upper chest. This is often seen in powerlifters and athletes after intense competition. Known as “effort petechiae,” the spots are harmless but serve as a reminder to breathe properly and avoid overstraining. If the marks persist or appear without physical exertion, however, it’s worth exploring other medical causes.
