Physical Effects of Stress on Your Body

The old adage of stress is a killer is truer than you may realize. To better understand what stress does to your body, let’s first take a look at stress. The Mayo Clinic defines stress as the natural alarm system to your body’s “flight or fight” reaction.

Stress is hardwired into your body and is as a way of alerting you of possible forthcoming danger. In the time of early man, stress was meant to protect against possible threats from predators. Today, our body still experiences stress, but for the most part the causes are different.

While it may be a good thing that we don’t have to fight for our life daily, the drawback sometimes results in accumulated stress for some people.

What is stress?

During a stressful situation, your body sounds off an alarm system in the small region of your brain, known as the hypothalamus.

Once activated, it sends a message to your adrenal glands to release hormones. These hormones include cortisol and adrenaline.

Cortisol affects certain body functions that may cause problems in a survival situation. It can change your immune system and slow down the digestive and reproductive systems. Cortisol is the main stress hormone that is responsible for increasing glucose in your blood stream.

Adrenaline can supercharge your energy supplies. It also speeds up your heart rate and can increase your blood pressure. After your body responds to a stressful event, your system should naturally calm down. Cortisol and adrenaline levels drop and your body should go back to its normal mode of operation.
