Stress is healthy

Well, it´s not that simple, but stress is not as bad as everyone believed for a long time and now there is even a study confirming  that stress 1.) is a clever way to respond to certain situations and 2.) has no negative effects, if you don´t believe in them. In other words stress just makes you sick, if you believe it is harmful. Many coaches have known that for quite a while, but there have not been any academical studies to confirm. Now Kelly McGonigal has shown on a TED conference in June, that what makes us sick is rather the belief than the stress itself.
