Garmin: All about stress

Updated: Oct 1

Stress is a natural part of being human, but how should we monitor and make changes for optimal health?

What is stress and how does it affect our body?


Stress is your body’s natural response to the challenges of life and the environment around you. It is an elevated physiological state that prepares you to react quickly to whatever comes next. It can have a profound impact on your body, affecting both physical and mental health. Here's how stress might manifest in various ways: 


1. Cardiovascular System

Stress triggers the release of hormones like adrenaline, causing the heart to beat faster and blood vessels to constrict, raising blood pressure. Chronic stress can lead to long-term issues such as hypertension, heart attacks, and strokes. Persistent stress can contribute to inflammation, a risk factor for atherosclerosis (hardening of the arteries), increasing the risk of heart disease.


2. Immune System

Stress suppresses the immune system, making the body more vulnerable to infections and illnesses. This is because stress hormones like cortisol can inhibit the production of cytokines, which are essential for immune function. Long-term stress can exacerbate conditions like autoimmune diseases and slow down the healing process.


3. Digestive System

Stress can lead to various digestive problems, including acid reflux, irritable bowel syndrome (IBS), and stomach ulcers. Stress can also affect appetite, leading to overeating or loss of appetite. Chronic stress can disrupt the balance of bacteria in the gut, affecting digestion and overall health.


4. Musculoskeletal System

Stress often causes muscles to tighten, which can lead to headaches, back pain, and body aches. Persistent muscle tension can contribute to long-term musculoskeletal problems. Tense muscles are more prone to strains and injuries, particularly in the neck, shoulders, and back.


5. Endocrine System

Stress triggers the release of stress hormones like cortisol and adrenaline. Over time, chronic stress can lead to hormonal imbalances, affecting metabolism, mood, and overall health. Stress can cause the liver to release glucose into the bloodstream, which, over time, can increase the risk of developing type 2 diabetes.


6. Mental Health

Chronic stress can contribute to the development of anxiety disorders and depression. It can also exacerbate existing mental health conditions. Stress can impair memory, concentration, and decision-making abilities, affecting daily functioning and quality of life.


7. Reproductive System

Stress can disrupt the menstrual cycle in women, leading to irregular periods or amenorrhea (absence of menstruation). In men, stress can affect testosterone levels, sperm production, and sexual performance.


8. Skin and Hair

Stress can exacerbate skin conditions like acne, eczema, and psoriasis. It can also cause hives or other stress-related skin reactions. Chronic stress can lead to hair thinning or loss, often in the form of a condition called telogen effluvium, where hair follicles enter a resting phase prematurely.


9. Respiratory System

Stress can cause rapid breathing or hyperventilation, which can exacerbate respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD). Intense stress or anxiety can trigger panic attacks, characterized by sudden, overwhelming feelings of fear and physical symptoms like chest pain and shortness of breath.


Understanding the impact of stress on the body underscores the importance of stress management techniques, such as regular exercise, mindfulness, healthy eating, and adequate sleep, to maintain overall health and well-being. A great way to monitor your stress is by using a smart watch.


How can I use my Garmin to track my stress?

All-day stress tracking on your Garmin smartwatch is based on a well-established and scientifically validated understanding of your autonomic nervous system (ANS).


Stress levels (0–100) are estimated by the Firstbeat Analytics engine, primarily using a combination of HR and HRV data. This data is recorded by the optical heart rate sensor on the back of your device.


Divided into sympathetic and parasympathetic branches, your ANS regulates your physiological systems to best match the expected demands of your current situation. The sympathetic branch dominates when it’s time for action. Your pulse quickens, blood vessels dilate, digestion is interrupted, and adrenaline flows. This is sometimes referred to as the fight-or-flight response. In quieter times, the parasympathetic branch is more dominant, and your body enters what is referred to as rest-and-digest mode. This is when your body can repair itself and replenish resources depleted during more hectic times.


Sleep is an especially important opportunity for your body to recover, and, predictably, the parasympathetic branch of your ANS is typically the most active when you are asleep.


Stress levels are not measured by your Garmin device during physical activity because the strain of physical activity itself can be considered stressful. The impact of physical activity is best measured and understood in other ways. Public speaking and running up a flight of stairs can both send your heart racing, but the underlying reasons why are fundamentally different.


Wear your device regularly for more personalised feedback

Your physiological parameters and your body’s response to stressors are unique. Accordingly, the analytics used to monitor your stress levels are designed to recognize and adapt to your own personal situation. You can improve the quality of the insight gained by wearing your device as much as possible, especially while you sleep, because that is when your stress levels will typically be lowest. This helps create a better understanding of the full range of stress and relaxation states that you experience.


Wearing your device intermittently will still provide some insight into your stress. The details and precise levels, however, may be less personalised compared to what you would see with more consistent usage.


Making sense of all-day stress tracking

Your stress data reveals your physiological states throughout the day, corresponding to activity occurring within your ANS as it works behind the scenes to regulate your body’s responses.


You can configure select Garmin devices to alert you when your stress level is unusually high. The alert encourages you to take a moment to relax, and the device will prompt you to begin a guided breathing exercise with the relaxation breathing timer.


The stress chart on your device or in the Garmin Connect™ app will show orange bars when your stress level is above 25. Below level 25, the stress chart turns blue. This contrast is the key to identifying stressed and relaxed states.


Around level 25, activity within the sympathetic (stress: fight-or-flight) and parasympathetic (recovery: rest-and-digest) branches of your ANS is roughly equal. At higher levels (25–100), sympathetic activity is more prevalent, preparing you for action. Lower levels (0–25) indicate your parasympathetic system is the more active of the two.

What your stress data doesn’t tell you is why these various states are occurring. That is why it’s important to increase your own awareness of stressors in your life and how your body responds. This is how you can make the most of the stress data your Garmin device collects and how you can work toward finding effective stress management strategies.


For example, elevated stress levels may stem from pressure at work, social anxiety or from something as simple as encountering an aggressive driver on the motorway. Elevated stress levels could also be the result of happier situations, such as the excitement of a new job, the thrill of a first date or the jitters a runner feels the morning of a big race. Keep in mind that excessive exercise, consumption of stimulants, poor nutrition and getting sick can also produce higher than normal stress levels.


Regardless of why you experience stress, the key to a healthy, well-balanced lifestyle is to offset these draining experiences with relaxing moments and good quality sleep.
