What Is Stress and What Are Stressors?
How to Recognize the Symptoms and Signs of Stress
Stress is a fact of life in our contemporary world. Stress and stressors come in a wide variety of forms.
They also take a heavy toll on the quality of your life.
Stress is so common that many people assume that feeling stressed-out is inevitable. You don’t have to go through life feeling stressed-out all the time. You owe it to yourself to find out when stress is an asset to your life and when stress is hurting you.

Stress Symptoms, Signs, and Causes
Modern life is full of frustrations, deadlines, and demands. For many people, stress is so commonplace that it has become a way of life. Stress isn’t always bad, though. Stress within your comfort zone can help you perform under pressure, motivate you to do your best, even keep you safe when danger looms. But when stress becomes overwhelming, it can damage your health, mood, relationships, and quality of life.
You can protect yourself by understanding how the body’s stress response works, recognizing the signs and symptoms of stress overload, and taking steps to reduce its harmful effects.
What is stress?
Stress is your body’s way of responding to any kind of demand or threat. When you feel threatened, your nervous system responds by releasing a flood of stress hormones, including adrenaline and cortisol, which 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.
This is known as the “fight or flight” stress response and is your body’s way of protecting you. When working properly, stress 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.
Stress can also help 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 your comfort zone, stress stops being helpful and can start causing major damage to your mind and body.
How do you respond to stress?
The latest research into the brain shows that we, as mammals, have three ways of regulating our nervous systems and responding to stress:
- Social engagement is our most evolved strategy for keeping ourselves feeling calm and safe. Since the vagus nerve connects the brain to sensory receptors in the ear, eye, face and heart, socially interacting with another person—making eye contact, listening in an attentive way, feeling understood—can calm you down and put the brakes on defensive responses like “fight-or-flight.” When using social engagement, you can think and feel clearly, and body functions such as blood pressure, heartbeat, digestion, and the immune system continue to work uninterrupted.
- Mobilization, otherwise known as the fight-or-flight response. When social engagement isn’t an appropriate response and we need (or think we need) to either defend ourselves or run away from danger, the body prepares for mobilization. It releases chemicals to provide the energy you need to protect yourself. At the same time, body functions not needed for fight or flight—such as the digestive and immune systems—stop working. Once the danger has passed, your nervous system calms the body, slowing heart rate, lowering blood pressure, and winding back down to its normal balance.
- Immobilization. This is the least evolved response to stress and used by the body only when social engagement and mobilization have failed. You may find yourself or “stuck” in an angry, panic-stricken or otherwise dysfunctional state, unable to move on. In extreme, life-threatening situations, you may even lose consciousness, enabling you to survive high levels of physical pain. However, until you’re able to arouse your body to a mobilization response, your nervous system may be unable to return to its pre-stress state of balance.
While it’s not always possible to respond to stress using social engagement, many of us have become conditioned to responding to every minor stressor by immediately resorting to fight or flight. Since this response interrupts other body functions and clouds judgment and feeling, over time it can cause stress overload and have a detrimental effect on both your physical and mental health.
Effects of stress overload
The body’s autonomic nervous system often does a poor job of distinguishing between daily stressors and life-threatening events. If you’re stressed over an argument with a friend, a traffic jam on your commute to work, or a mountain of bills, for example, your body can still react as if you’re facing a life-or-death situation.
When you repeatedly experience the fight or flight stress response in your daily life, it can raise blood pressure, suppress the immune system, increase the risk of heart attack and stroke, speed up the aging process and leave you vulnerable to a host of mental and emotional problems.
Many health problems are caused or exacerbated by stress, including:
- Pain of any kind
- Heart disease
- Digestive problems
- Sleep problems
- Weight problems
- Auto immune diseases
- Skin conditions, such as eczema
