Stress Affects Your Body and Mind

Stress is a natural physical and mental reaction to life experiences. Anything from everyday responsibilities like feeding your family to more serious life events like a car accident can trigger stress. In immediate, short-term situations, stress can help you cope with potentially serious situations.

Your body responds to stress by releasing hormones that increase your heart and breathing rates and ready your muscles to respond. However, if this response continues longer than necessary for survival, it can take a toll on your health. Chronic stress can affect your overall well-being, with symptoms impacting many of your body’s systems.

Central Nervous & Endocrine Systems

Your central nervous system controls the “fight or flight” response. When you’re stressed, your brain’s hypothalamus signals your adrenal glands to release adrenaline and cortisol. These hormones increase your heart rate and direct blood to muscles and vital areas. Once the threat is over, the hypothalamus should signal the body to return to normal. If the stressor continues or the CNS doesn’t reset, the response continues.

Respiratory & Cardiovascular Systems

Stress hormones affect your respiratory and cardiovascular systems. Under stress, you breathe faster, your heart beats faster, and your blood vessels constrict in order to quickly distribute oxygen-rich blood to your body. Frequent or chronic stress can aggravate breathing problems and put you at risk for high blood pressure, heart attack or stroke.

Digestive System

Under stress, your liver produces extra blood sugar to give you more energy. However, if you’re experiencing chronic stress, your body may not be able to keep up with this surge, increasing your risk of developing type 2 diabetes.

Other systems’ reactions can also upset your digestive systems and affect the way food moves through your body, causing symptoms like nausea and indigestion. This response, paired with an increase in stomach acid may also produce heartburn or acid reflux. While stress doesn’t cause ulcers, it can make existing ones worse.

Muscular System

Your muscles tense up to protect themselves from injury when you’re stressed. They tend to release again once you relax, but if you’re constantly under stress, your muscles may not get the chance to relax. Tight muscles can cause headaches, back and shoulder pain, and body aches. Over time, this can create an unhealthy cycle, especially if you stop exercising and rely on pain medication for relief.

Sexuality & Reproductive System

Stress is exhausting for both the body and mind, often leading to reductions in sexual drive.  

For men, chronic stress can reduce men’s testosterone levels, affecting sperm production and causing erectile dysfunction. Chronic stress may also increase risk of infection for male reproductive organs like the prostate and testes.

For women, stress can affect the menstrual cycle, causing irregular, heavier, or more painful periods. Chronic stress can also lead to fertility issues and magnify the physical symptoms of menopause.

Immune System

Stress initially stimulates the immune system, which can help you heal wounds and defend against infections. However, over time, stress hormones will weaken your immune system and reduce your body’s ability to fight illness. People under chronic stress are more susceptible to the flu, colds, and other viral illnesses. Stress can also lengthen recovery time for illnesses or injuries.

Stress in America

While many celebrated a return to “normal” after the COVID-19 pandemic, the latest Stress in America™ survey reveals a more complex reality. According to psychologists from the American Psychological Association (APA), the perception of normalcy has overshadowed the lasting posttraumatic effects of the pandemic and other recent crises.

APA psychologists agree that these survey responses highlight the ongoing psychological and physical repercussions of recent crises. The stress experienced due to the pandemic offers a model for improving stress responses and managing lasting trauma from a variety of key stressors.

Key Sources of Stress:

  • COVID-19 aftermath
  • Global conflicts
  • Cries of racism and racial injustice
  • Inflation and economic instability
  • Perceived climate-related disasters
  • Rising rates of chronic illnesses 


The Stress in America 2023: A Nation Recovering from Collective Trauma
report examines the lasting psychological impacts of these events. Analysis of pre- and post-pandemic mental and physical health reveals signs of collective trauma across all age groups. Data indicates significant long-term effects and signs of collective trauma across all age groups, with a notable rise in chronic illnesses and mental health diagnoses.

  • Ages 35 to 44, chronic illness increased from 48% in 2019 to 58% in 2023
  • Ages 35 to 44, largest rise in mental health diagnoses from 31% in 2019 to 45% in 2023
  • Ages 18 to 34 reported the highest rate of mental health issues at 50% in 2023


Prolonged stress affects people’s overall life outlook, sensitivity to daily stressors, and physical  stress responses, which can lead to health issues. Ongoing stress keeps the body on high alert, leading to inflammation, immune system wear, and an increased risk of ailments such as digestive issues, heart disease, weight gain, cancer and stroke.


Building Resilience and Healing

Stress and trauma are universal experiences that impact people in different ways. The collective trauma caused by recent global events highlights the need for resilience and healing strategies that go beyond individual coping mechanisms. Addressing lasting trauma requires acknowledging losses, managing psychological wounds, and encouraging open conversations about stress and trauma to build resilience.

Whether coping with the posttraumatic effects of COVID-19, military experiences, natural disasters, or other traumatic events, these tactics remain true. By addressing these needs, we can foster a healthier, more compassionate society that is better equipped to handle the stressors of the future.
