In an ideal world, you are perfect. You are good at your job, your boss loves you, as do your spouse and children. But only you can feel your head throbbing constantly and off late you find your hand shaking when holding your toothbrush. Appearances are deceptive and also very stressful to keep up. It’s time to call the shots, don’t let circumstances dictate your life. Say goodbye to stress for good!

Who can get stressed?

Stress can affect anyone, anytime, anyplace. What’s important to know is that stress can actually be good for you (eustress). It is only when stress reaches unimaginable levels that it hinders your progress and makes you feel frustrated and sad (distress). This theory was proposed by Hans Selye, a pioneer in the field of stress.

Consider this scenario. You are on a roller coaster ride. As the roller coaster gathers pace, you feel happy and excited. Other people are screaming and wailing. Some are hysterical with fear. Clearly, the same stimulus can evoke different reactions in different people. What could be horrifying to someone could be gratifying to you. As the saying goes, one man’s food is another man’s poison.

What happens when we are stressed?

When confronted with a stressful situation, the human body (due to genetic programming) retreats to its survival instincts. Our ancestors had much sharper senses of sight, smell, touch, hearing and taste. This is because they needed these while hunting for food and to detect the presence of predators. This is aptly termed ‘the fight or flight response’. This response is alive and active even today. It causes the release of steroids (cortisol) and adrenaline from various glands in the body. These hormones spur all the systems, like respiratory, cardio-vascular, abdominal, endocrine and nervous systems, into overdrive.
