Stress comes at us from all directions. It can be hard to find balance in the stimulating, fast-paced, modern world most people live in. But aside from \u201cobvious\u201d stressors, science suggests we might be adding to our stress levels unknowingly through more nuanced dietary and lifestyle factors. Read on to learn some surprising ways you might be setting off your stress response<\/a>.<\/p>\n

<\/p>\n

Disclaimer<\/em><\/strong>: This post focuses on the neuroscience of the stress response, particularly in relation to cortisol. It is solely informational. Talk to your healthcare provider if you feel like you\u2019re under too much stress or if your cortisol labs are abnormal. <\/em><\/p>\n

What is Stress?<\/strong><\/span><\/h2>\n

Stress Isn\u2019t Always Bad<\/span><\/h3>\n

First of all, don\u2019t worry about everything that may activate the stress pathway. It\u2019s natural and healthy for this pathway to be activated moderately. That said, it\u2019s certainly not<\/em> supposed to be activated constantly<\/em> and excessively<\/em>.<\/p>\n

What we generally think of as stress includes both psychological or social stress. Psychological\/social stress is a broad term. It could be, for example, worry about income. It could be job- or relationship-related stress, and it could be so much more (R<\/a>, R<\/a>).<\/p>\n

Stress comes in innumerable forms. It can be internal or external. It can be positive stress or negative stress. It can be physical or emotional. It can be due to our own decisions, or totally out of our control. No matter how it comes packaged, stress has a huge impact on us: body, mind, and spirit.<\/p>\n

According to one hypothesis, the problem comes when the stress response is activated too little, too much, or when it doesn’t have a good rhythm. In other words, HPA \u201cdysregulation\u201d is viewed as bad (R<\/a>).<\/p>\n

Studies suggest that anxiety<\/a>, which is tightly linked with chronic stress, can be self-perpetuating. Scientists hypothesize that chronic stress increases CRH<\/a> receptors in the brain (paraventricular nucleus), which makes people even more susceptible to the harmful effects of stress (R<\/a>).<\/p>\n

For a more detailed outlook on these mechanisms, read our post on why stress is bad<\/a>.<\/p>\n

Limitations<\/strong><\/span><\/h3>\n

Note that the HPA axis (and CRH) is not the only system that participates in the stress response. Your sympathetic nervous system (SNS) is a different arm of the stress response. As an example, beta 2-adrenoreceptor blockers like propranolol block beta receptors in the heart that belong to the SNS (R<\/a>).<\/p>\n

Sympathetic, fight-or-flight activity can also be counteracted by parasympathetic, rest-and-digest activity. This is part of the cholinergic pathway in the body<\/a>.<\/p>\n

Lastly, the stress response can involve many other possible factors – including brain chemistry, environment, health status, and genetics – that may vary from one person to another.<\/p>\n

Individual Variations<\/span><\/h3>\n

Everyone is affected differently by stress. Research suggests that some conditions\/syndromes can also affect the way we respond to stress.<\/p>\n

For example, autistic children release higher amounts of cortisol in response to psychological stress and it takes longer for their cortisol to return to normal – according to one small study (R<\/a>).<\/p>\n

In another study, people with IBS<\/a> released more ACTH<\/a> in response to CRH<\/a> compared to people without IBS (R<\/a>).<\/p>\n

A Note About Factors that May Raise the Stress Response<\/span><\/h3>\n

Remember that it\u2019s natural and healthy for the stress response to be activated moderately and for a short time. Issues usually arise when activation becomes chronic [R<\/a>].<\/p>\n

If your goal is to improve extreme stress-related issues – including those of panic disorders or anxiety – it\u2019s important to talk to your doctor, especially if stress is significantly impacting your daily life.<\/p>\n

Major mental changes, such as excessive sadness, panic, persistent low mood, euphoria, or anxiety, are all reasons to see a doctor.<\/p>\n

Your doctor should diagnose and treat any underlying conditions causing your symptoms.<\/strong><\/p>\n

Additionally, changes in brain and body chemistry are not something that people can change on their own with the approaches listed in this article. Instead, the factors to avoid listed here are meant to reduce daily stress and support overall mental health and well-being.<\/p>\n

You may try avoiding the factors listed below if you and your doctor determine that this could be an appropriate approach for reducing your stress response<\/strong>.<\/p>\n

Avoiding these triggers should never be done in place of what your doctor recommends or prescribes.<\/p>\n

Lastly, clinical evidence is lacking to support avoiding many of the factors listed below as a means of stress reduction.<\/p>\n

Lifestyle Choices that May Raise the Stress Response<\/strong><\/span><\/h2>\n

Exhaustion and Body Posture<\/span><\/h3>\n
    \n

  2. Strenuous Breathing <\/strong>– Raises IL-6<\/a> and IL-1<\/a> in healthy volunteers (R<\/a>)<\/li>\n
  3. Long commutes<\/strong> – Increased cortisol (humans) (R<\/a>)<\/li>\n
  4. Low Power Postures<\/strong> – Body positions that make you appear less confident\/dominant (e.g. slumped shoulders) increased cortisol, according to small human studies (R<\/a>)<\/li>\n<\/ol>\n

    Addictive Drugs<\/span><\/h3>\n
      \n
    1. Excess Alcohol consumption<\/strong> – Ongoing consumption of alcohol raises cortisol levels in the body (R<\/a>)<\/li>\n
    2. Smoking<\/strong> – Even just 2 cigarettes (R<\/a>)<\/li>\n
    3. Marijuana<\/strong><\/a>\/Pot\/<\/strong>THC<\/strong><\/a> – Dose dependently raises cortisol in human studies (R<\/a>)<\/li>\n
    4. Opioid withdrawal <\/strong>– Withdrawal from chronic morphine-induced the HPA axis<\/a> in rat studies (R<\/a>)<\/li>\n<\/ol>\n

      Sleep Disruption<\/span><\/h3>\n
        \n
      1. Reduced Sleep<\/strong> – A loss of sleep<\/a> for just one night leads to higher cortisol levels the next evening (R<\/a>, R<\/a>)<\/li>\n
      2. Poor quality sleep<\/strong> – Poor quality sleep activates the HPA axis<\/a> (stress response) (R<\/a>)<\/li>\n
      3. Staying up late<\/strong> – Cortisol goes up when we are awake during normal sleep times (R<\/a>)<\/li>\n
      4. Circadian Rhythm<\/strong><\/a> Disruptions <\/strong>– An airline cabin crew who had chronic circadian<\/a> disruptions had higher salivary cortisol (R<\/a>). See how to keep to a Circadian Rhythm<\/a>.<\/li>\n<\/ol>\n

        Stimulants<\/span><\/h3>\n

        3. Yohimbine<\/strong><\/a> – increases cortisol (humans) (R<\/a>)<\/li>\n<\/ol>\n

          Toxins<\/span><\/h3>\n
            \n

          2. Mercury<\/strong> in fish (humans) (R<\/a>)<\/li>\n
          3. PAH<\/strong> (Polycyclic Aromatic Hydrocarbons) (R<\/a>)<\/li>\n<\/ol>\n

            Other Environmental Influences<\/span><\/h3>\n

            Scientists are exploring if these environmental factors can also heighten the stress response:<\/p>\n

              \n
            1. Noise<\/strong> – Induces an HPA axis response (rats) (R<\/a>)<\/li>\n
            2. Excess sun<\/strong><\/a>\/UVB<\/strong> exposure (locally, on the skin) – Induces skin cells to produce and release CRH through the PKA pathway (R<\/a>)<\/li>\n
            3. Cold<\/strong><\/a> (R<\/a>) or Hot<\/strong> (R<\/a>) temperatures (humans). Chronic cold increases CRH receptors, caused by dopamine<\/a> (rats) (R<\/a>)<\/li>\n
            4. EMFs<\/strong><\/a> – Seem to raise stress levels (rats) (R<\/a>)<\/li>\n
            5. High altitudes <\/strong>– Lower oxygen<\/a> (potentially causing hypoxia<\/a>), increasing the stress response (rat, cellular, humans) (R<\/a>)<\/li>\n<\/ol>\n

              Large-scale human data are lacking.<\/p>\n

              Dietary Factors that May Raise the Stress Response<\/strong><\/span><\/h2>\n

                    Internal Psychological Chatter?<\/strong><\/span><\/h2>\n

                    Psychological Approaches<\/span><\/h3>\n

                    Psychologists suggest that some attitudinal factors may increase the stress response, but they don\u2019t have scientific references.<\/p>\n

                    The exact approach will vary on the psychologist\u2019s training. For example, a CBT therapist, a Gestalt psychologist, a Freudian psychoanalyst, and a Jungian psychotherapist would probably not agree on all the ideas listed below.<\/p>\n

                    So here\u2019s a list of various things different psychologists might tell you to watch out for if your nervous system is overactive.<\/p>\n

                    If you want to change your attitude and behavior, consider seeing a psychotherapist that matches your goals and personality.<\/p>\n
