Sure, stress is universal and unavoidable. And today, the world is undoubtedly getting even more chaotic. Often enough, while working within the chaos we unconsciously allow it to become part of our everyday. It may not seem unmanageable at first but when we give in to stress, it sooner or later finds its way around and expresses itself even in the unrelated aspects of our lives. If we ignore it or leave it undetected over a period of time, it can ultimately build up to more complex forms of psychological distress.
So where does mindfulness come in? Well, our spiritual gurus, as expected, were far from wrong. Empirically speaking, learning to be mindful and consciously practicing the concepts of mindfulness everyday has proved to be effective in the fight against increasingly common forms of clinical distress like anxiety, fear, worry, anger, depression and trauma. However, it is not only helpful in intervening, but also in preventing the occurrence of distress as it keeps the mind healthy thereby increasing subjective wellbeing.
