What is stress?
Modern life is full of hassles, deadlines, frustrations, and demands. For many people, stress is so commonplace that it has become a way of life. Stress isn't always bad. In small doses, it can help you perform under pressure and motivate you to do your best. But when you're constantly running in emergency mode, your mind and body pay the price.
If you frequently find yourself feeling frazzled and overwhelmed, it's time to take action to bring your nervous system back into balance. You can protect yourself by learning how to recognize the signs and symptoms of stress and taking steps to reduce its harmful effects.
The Body's Stress Response
When you perceive a threat, your nervous system responds by releasing a flood of stress hormones, including adrenaline and cortisol. These hormones rouse the body for emergency action.
Your heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and your senses become sharper. These physical changes increase your strength and stamina, speed your reaction time, and enhance your focus - preparing you to either fight or flee from the danger at hand.
Stress is a normal physical response to events that make you feel threatened or upset your balance in some way. When you sense danger whether it's real or imagined - the body's defence's kick into high gear in a rapid, automatic process known as the "fight-or-flight" reaction, or the stress response.
The stress response is the body' way of protecting you. When working properly, it helps you stay focused, energetic, and alert. In emergency situations, stress can save your life - giving you extra strength to defend yourself, for example, or spurring you to slam on the brakes to avoid an accident.
The stress response also helps you rise to meet challenges. Stress is what keeps you on your toes during a presentation at work, sharpens your concentration when you're attempting the game-winning free throw, or drives you to study for an exam when you'd rather be watching TV.
But beyond a certain point, stress stops being helpful and starts causing major damage to your health, your mood, your productivity, your relationships, and your quality of life.
Effects of chronic stress
The body doesn't distinguish between physical and psychological threats. When you're stressed over a busy schedule, an argument with a friend, a traffic jam, or a mountain of bills, your body reacts just as strongly as if you were facing a life-or-death situation.
If you have a lot of responsibilities and worries, your emergency stress response may be "on" most of the time. The more your body's stress system is activated, the easier it is to trip and the harder it is to shut off.
Long-term exposure to stress can lead to serious health problems. Chronic stress disrupts nearly every system in your body. It can raise blood pressure, suppress the immune system, increase the risk of heart attack and stroke, contribute to infertility, and speed up the aging process.
Long-term stress can even rewire the brain, leaving you more vulnerable to anxiety and depression.
