Stress Symptoms & Signs

he Effects of Stress Overload and What You Can Do About It

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. You can protect yourself by recognizing the signs and symptoms of stress and taking steps to reduce its harmful effects.

What is stress?

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 defenses kick into high gear in a rapid, automatic process known as the “fight-or-flight-or-freeze” reaction, or the stress response.

The stress response is the body’s 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.

How do you respond to stress?

It's important to learn how to recognize when your stress levels are out of control. The most dangerous thing about stress is how easily it can creep up on you. You get used to it. It starts to feel familiar, even normal. You don't notice how much it's affecting you, even as it takes a heavy toll.

The signs and symptoms of stress overload can be almost anything. Stress affects the mind, body, and behavior in many ways, and everyone experiences stress differently. Not only can overwhelming stress lead to serious mental and physical health problems, it can also take a toll on your relationships at home, work, and school.

Stress doesn’t always look stressful

Psychologist Connie Lillas uses a driving analogy to describe the three most common ways people respond when they’re overwhelmed by stress:

• Foot on the gas – An angry, agitated, or “fight” stress response. You’re heated, keyed up, overly emotional, and unable to sit still.
• Foot on the brake – A withdrawn, depressed, or “flight” stress response. You shut down, pull away, space out, and show very little energy or emotion.
• Foot on both – A tense or “freeze” stress response. You become frozen under pressure and can’t do anything. You look paralyzed, but under the surface you’re extremely agitated.

Signs and symptoms of stress overload

The following table lists some of the common warning signs and symptoms of stress. The more signs and symptoms you notice in yourself, the closer you may be to stress overload.

Stress Warning Signs and Symptoms
Cognitive Symptoms	Emotional Symptoms
Memory problems Inability to concentrate Poor judgment Seeing only the negative Anxious or racing thoughts Constant worrying	Moodiness Irritability or short temper Agitation, inability to relax Feeling overwhelmed Sense of loneliness and isolation Depression or general unhappiness
Physical Symptoms	Behavioral Symptoms
Aches and pains Diarrhea or constipation Nausea, dizziness Chest pain, rapid heartbeat Loss of sex drive Frequent colds	Eating more or less Sleeping too much or too little Isolating yourself from others Procrastinating or neglecting responsibilities Using alcohol, cigarettes, or drugs to relax Nervous habits (e.g. nail biting, pacing)

Keep in mind that the signs and symptoms of stress can also be caused by other psychological or medical problems. If you’re experiencing any of the warning signs of stress, it’s important to see a doctor for a full evaluation. Your doctor can help you determine whether or not your symptoms are stress-related.

How much stress is too much?

Because of the widespread damage stress can cause, it's important to know your own limit. But just how much stress is "too much" differs from person to person. We're all different. Some people are able to roll with the punches, while others seem to crumble in the face of far smaller obstacles or frustrations. Some people even seem to thrive on the excitement and challenge of a high-stress lifestyle.

Your ability to tolerate stress depends on many factors, including the quality of your relationships, your general outlook on life, your emotional intelligence, and genetics.

Things that influence your stress tolerance level

• Your support network – A strong network of supportive friends and family members can be an enormous buffer against life’s stressors. On the flip side, the more lonely and isolated you are, the greater your vulnerability to stress.
• Your sense of control – It may be easier to take stress in your stride if you have confidence in yourself and your ability to influence events and persevere through challenges. If you feel like things are out of your control, you’re likely to have less tolerance for stress.
• Your attitude and outlook – Optimistic people are often more stress-hardy. They tend to embrace challenges, have a strong sense of humor, and accept that change is a part of life.
• Your ability to deal with your emotions – You’re extremely vulnerable to stress if you don’t know how to calm and soothe yourself when you’re feeling sad, angry, or overwhelmed by a situation. The ability to bring your emotions into balance helps you bounce back from adversity and is a skill that can be learned at any age.
• Your knowledge and preparation – The more you know about a stressful situation, including how long it will last and what to expect, the easier it is to cope. For example, if you go into surgery with a realistic picture of what to expect post-op, a painful recovery will be less traumatic than if you were expecting to bounce back immediately.
