Exercise Can Trigger Some Strange Side Effects

Everybody knows exercise is good for you. So the more you do it, the better you should feel, right?

Not always.

All that lifting, lunging and long-arm crunching can trigger some unusual side effects -- from a pounding headache to an unexpected orgasm to a runny nose.

"People put a lot of stress on their body they're not used to," said Steven Page, a sports medicine specialist at Brandon Orthopedic Associates. "They start a new routine, or increase the intensity, or they don't work out regularly and do a heavy workout; they can all be triggers."

Some problems are the result of inadequate nutrition or hydration, said fitness expert Jennifer Cassetty.

"What you put in your body is what you're going to get out of it," Cassetty said. "Good hydration ensures you can sustain physical activity. If you don't have the proper foundation, it's going to throw everything out of whack -- which can cause the body to experience some problems."

Experts say when you start a workout program, build the intensity slowly, exercise regularly and maintain proper nutrition.

"Even if you're predisposed to certain illnesses, exercising regularly can prevent them," Cassetty said. "But before you start an exercise regimen, you need to make sure there are no underlying health issues that could cause problems."
