How often do you get stressed? Maybe it’s time to up the frequency. This may sound counterintuitive but there’s a growing body of research that says that exposing ourselves to short, sharp bouts of stress is good for our health. It increases our resilience, can protect us against disease and can even help us live longer, healthier lives. It’s a biological phenomenon known as hormesis or hormetic stress and, simply put, is the principle that what doesn't kill you makes you stronger… up to a point.
