Life is full of stress, good stress and bad stress, otherwise known as eustress and distress. An example of eustress is when a professional athlete gets ready for competition. The surge of adrenaline helps them to perform. On the other hand, if someone is dealing with a challenging situation, such as repeated arguments with a spouse or increasing financial demands, they may experience a wide variety of negative effects. Regardless, long-term exposure to stress can cause a significant strain on the human system.
