Exercise Extremism

Devotees to extreme sports enjoy the excitement and thrills of what they do. But you could also be a junkie by just running, the same activity encouraged by virtually everyone in the health industry.
Experts have now discovered that overreaction to an urge to exercise sparks a reaction in the brain that is similar to heroin – and it is just as addictive. It can get worse. A sudden withdrawal can lead to trembling, writhing and teeth chattering.
Writing in the medical journal Behavioural Neuroscience, researchers found that a desire to go out there e.g. the park, beaches etc for the purpose of shedding a few pounds can quickly become as compulsive as Class A narcotics. So mild exercise like jogging can develop into a serious triathlon or marathon habit. "Although exercise is good for your health, extreme exercise may be physically addictive," they warned.
