Solar eclipses occur fairly frequently, typically two to five times per year. One possible explanation as to why this fact may surprise people is due to the relatively small area of the ground covered totally during a solar eclipse. Unlike a lunar eclipse, which covers roughly half of Earth's surface, a solar eclipse only covers a few miles in width. Although human beings have spent millennia associating solar eclipses with doom, no such evidence exists to suggest such theories are accurate. What's more, no evidence exists supporting the theory that solar eclipses can have a profound physical effect on the human body.
