Stress: We’ve all felt it. Sometimes stress can be a positive force, motivating you to perform well at your piano recital or job interview. But often—like when you’re stuck in traffic—it’s a negative force. If you experience stress over a prolonged period of time, it could become chronic—unless you take action.

A Natural Reaction

Have you ever found yourself with sweaty hands on a first date or felt your heart pound during a scary movie? Then you know you can feel stress in both your mind and body.

This automatic response developed in our ancient ancestors as a way to protect them from predators and other threats. Faced with danger, the body kicks into gear, flooding the body with stress hormones such as adrenaline and cortisol that elevate your heart rate, increase your blood pressure, boost your energy, and prepare you to deal with the problem.

These days, you’re not likely to face the threat of being eaten. But you probably do confront multiple challenges every day, such as meeting deadlines, paying bills, and juggling childcare that makes your body react the same way. As a result, your body’s natural alarm system—the “fight or flight” response—may be stuck in the on position. And that can have serious consequences for your health.

Chronic Stress

When stress starts interfering with your ability to live a normal life for an extended period, it becomes even more dangerous. The longer the stress lasts, the worse it is for both your mind and body. You might feel fatigued, unable to concentrate, or irritable for no good reason, for example. But chronic stress causes wear and tear on your body, too.

The long-term activation of the stress response system and the overexposure to cortisol and other stress hormones that come with it can disrupt almost all of your body’s processes. This can put you at increased risk for a variety of physical and mental health problems, including anxiety, depression, digestive issues, headaches, muscle tension and pain, heart disease, heart attack, high blood pressure, stroke, sleep problems, weight gain, and memory and concentration impairment.

Chronic stress may also cause disease, either because of changes in your body or the overeating, smoking, and other bad habits people use to cope with stress. Job strain—high demands coupled with low decision-making latitude—is associated with an increased risk of coronary disease, for example. Other forms of chronic stress, such as depression and low levels of social support, have also been implicated in increased cardiovascular risk.

Chronic stress also suppresses the body’s immune system, making it harder to recover from illnesses.

What you can do

Reducing your stress levels can not only make you feel better right now but may also protect your health long-term. Several research studies have demonstrated, for example, that interventions to improve psychological health can have a beneficial impact on cardiovascular health. As a result,  researchers recommend boosting your positive affect—feelings like happiness, joy, contentment, and enthusiasm—by making time for enjoyable activities every day.

Other strategies for reducing stress include:

• Identify what’s causing stress
• Build strong relationships, negative relationships, and hostile reactions can be a source of stress.
• Walk away when you’re angry. Before you react, take time to regroup by counting to 10. Then reconsider. Walking or other physical activities can also help you work off steam. Plus, exercise increases the production of endorphins, your body’s natural mood booster.
• Rest your mind. To help ensure you get the recommended seven or eight hours of shut-eye, cut back on caffeine, remove distractions such as television or computers from your bedroom, and go to bed at the same time each night.
• Get help. If you continue to feel overwhelmed, consult with a psychologist or other licensed mental health professional who can help you learn how to manage stress effectively.
