When the natural stress response goes haywire

The body's stress-response system is usually self-limiting. Once a perceived threat has passed, hormone levels return to normal. As adrenaline and cortisol levels drop, your heart rate and blood pressure return to baseline levels, and other systems resume their regular activities.

But when stressors are always present and you constantly feel under attack, that fight-or-flight reaction stays turned on.

The long-term activation of the stress-response system — and the subsequent overexposure to cortisol and other stress hormones — can disrupt almost all your body's processes. This puts you at increased risk of numerous health problems, including:

• Anxiety
• Depression
• Digestive problems
• Headaches
• Heart disease
• Sleep problems
• Weight gain
• Memory and concentration impairment

That's why it's so important to learn healthy ways to cope with the stressors in your life.
