Stress is part of everyday life. In small doses, it can help you stay focused and tackle challenges. But when stress builds up or lasts for a long time, it can affect both your mental and physical health.
Stress can cause new symptoms and make the health problems you already have feel worse or harder to manage. Recognizing the ways stress affects your health can help you get the care you need.
What is stress?
Stress is your body’s response to a challenging or demanding situation. “It is a feeling that can happen when you are placed under pressure,” said Anais Balaci, a behavioral health specialist with Banner Health. It triggers a “fight or flight” response that’s designed to protect you.
How stress affects your body in the short term
When you experience a stressful situation, it triggers hormones that can cause:
- Increased heart rate
- Higher blood pressure
- Faster breathing
- Tense muscles
Sometimes, this extra alertness can be helpful. For example, it can help you avoid accidents. But your body isn't meant to stay in this state for long. When the "fight or flight" response doesn't turn off, it can impact your health.
How chronic stress affects your physical health
Chronic stress occurs when your body stays on high alert for days, weeks or months. This long-term stress can lead to ongoing high blood pressure. Over time, it increases the risk of heart disease and heart attack.
Stress also weakens your immune system, making it harder to fight infections. You may have digestive issues, poor sleep or fatigue. These physical symptoms are your body's way of telling you that it is overwhelmed.
How stress can amplify existing health symptoms
Stress doesn’t just create new problems. It can make existing conditions feel worse.
- Pain and inflammation: Chronic stress can make you more sensitive to pain. It can make headaches, back pain or joint discomfort worse. When you feel stressed, tight muscles can add to physical strain.
- Heart and circulation: Stress raises your heart rate and blood pressure. If you have existing heart conditions, this extra strain can make your symptoms more severe or harder to control.
- Digestive issues: The gut and brain are closely connected. Stress can make nausea, stomach pain or symptoms of irritable bowel syndrome (IBS) worse.
- Respiratory symptoms: Because stress tightens the muscles that help you breathe, high stress levels can make asthma worse or cause shortness of breath.
- Skin changes: Stress may trigger flare-ups in eczema or acne.
- Immune responses: Stress suppresses your immune system, which can lead to autoimmune flares or make you more prone to common illnesses.
Mental and emotional effects of stress
The mental impact of stress means you may:
- Feel anxious, worried or irritable
- Struggle with racing thoughts
- Have trouble focusing on daily tasks
- Notice mood changes
- Procrastinate
- Be at risk of depression over time
Common signs stress may be affecting your health
Recognizing the signs of stress is the first step toward feeling better. “It is important to identify when you are experiencing stress at a toxic level,” Balaci said.
You might notice you:
- Have trouble sleeping
- Wake up feeling tired
- Don’t have much energy
- Get sick more often than usual
- Have frequent headaches
- Notice muscle tension in your neck or shoulders
- Feel overwhelmed or burned out
How to manage stress in healthy ways
“Work on reducing stress whenever possible. You can start simple habits today,” Balaci said.
- Physical activity: Regular movement helps manage your stress hormones, improve your mood and boost your energy. Even a short walk can help clear your mind.
- Relaxation techniques: eep breathing and meditation are powerful ways to calm your nervous system. You may also want to try yoga or tai chi, which combine movement with focus.
- Sleep: A consistent sleep routine helps your body recover from the effects of stress. Limit alcohol and caffeine, since they can make you feel more anxious.
- Diet: Balanced meals help keep your energy steady.
- Social support: Don’t isolate yourself when things feel difficult. Talk with friends, family or a mental health provider. Sharing your concerns can reduce the weight of stress.
When to seek help for stress
It is important to know when lifestyle changes aren't enough. Seek help from a health care provider if:
- Stress feels constant
- Stress interferes with your work, relationships or daily life
- Your physical symptoms are getting worse
- You find it hard to cope
