Understanding Chronic Stress and Its Impact on Health

Chronic stress is a pervasive issue, which affects all of us in the modern world. At Longtail Nutrition, we recognise the multifaceted nature of stress and offer comprehensive strategies to manage and mitigate its impact. This page explores the types of stress, its far-reaching effects on the body, and how nutrition and lifestyle adjustments can help you manage chronic stress.

Stress is a natural and essential part of our survival mechanism, enabling us to respond quickly to threats through the "fight or flight" response. In acute situations, stress can enhance our alertness, strength, and speed, crucial for overcoming immediate dangers. However, when stress becomes chronic, it can have a detrimental impact on various bodily processes and overall health. Prolonged stress leads to the continuous release of cortisol and adrenaline, hormones that, in excess, can disrupt normal physiological functions. Chronic stress can impair immune function, increase the risk of cardiovascular disease, disrupt digestion, and contribute to mental health issues such as anxiety and depression. Thus, while acute stress is beneficial and necessary for survival, chronic stress can undermine our health and well-being.

Types of Stress

Emotional and Mental Stress

Emotional and mental stress stems from various sources, including personal relationships, financial worries, and life changes. These stressors can lead to persistent anxiety and depression if not managed effectively.

Work-Related Stress

Work stress is common in today's fast-paced environment. Deadlines, heavy workloads, and job insecurity can contribute to ongoing stress, impacting both mental and physical health.

Physical Stress

Physical stress might not be as immediately recognisable as emotional or work-related stress, but it plays a significant role in overall levels. Physical stress factors include:

Imbalanced Blood Sugars: Fluctuations in blood sugar levels can increase the release of adrenaline and cortisol, the body's primary stress hormones.

Overtraining: Excessive exercise without adequate recovery can lead to physical stress, depleting the body's energy reserves and increasing cortisol levels.

Chronic Health Conditions: Inflammation resulting from chronic health issues—whether they are gut-related, autoimmune, or diabetes—can significantly contribute to the body's overall stress load. This persistent inflammation not only exacerbates the underlying conditions but also increases the physiological strain, leading to a vicious cycle of stress and health deterioration.

The Impact of Stress on the Body

Chronic stress has far-reaching impacts on the body, affecting everything from hormone levels to immune function. Here are some key ways stress manifests physically:

Increased Cortisol

Cortisol, known as the stress hormone, is released in response to stress. While beneficial in short bursts, chronic elevation can lead to numerous health problems, including weight gain, high blood pressure, and metabolic issues.

Nutrient Depletion

During periods of stress, the body prioritises immediate survival over other processes, leading to nutrient depletion. Essential vitamins and minerals are used up more rapidly, compromising overall health.

Lowered Immunity

Chronic stress weakens the immune system, making you more susceptible to infections and illnesses. The constant release of cortisol can suppress the immune response, leading to increased vulnerability.

Digestive Issues

The gut-brain axis is a bidirectional communication system linking the digestive system and the brain. Stress can disrupt this connection, contributing to digestive issues such as irritable bowel syndrome (IBS), bloating, and discomfort.

Blood Pressure

Persistent stress keeps the body in a state of heightened alert, increasing blood pressure. This can elevate the risk of cardiovascular diseases over time.

Sleep Issues

Stress often leads to sleep disturbances, including difficulty falling asleep, staying asleep, or experiencing restful sleep. Poor sleep quality further exacerbates stress and its health impacts.

Hormone Imbalances

Chronic excessive cortisol output can disrupt hormone balance, affecting everything from reproductive health to thyroid function. Hormonal imbalances can lead to irregular menstrual cycles, infertility, and metabolic issues.

Mood Changes

Chronic stress significantly impacts mood, leading to symptoms of anxiety and depression. The persistent strain on mental health can reduce overall quality of life.


The constant state of alertness associated with chronic stress can lead to fatigue via the hypothalamus-pituitary-adrenal (HPA) axis. The adrenal glands regulate our response to stress, however if they can become overworked and overloaded an individual can end up with an overproduction or underproduction of cortisol or a combination due to dysregulation.

Excessive cortisol release in response to stressors can lead to hypothyroidism. The HPA axis is closely linked to the hypothalamus-pituitary-thyroid axis. (This is something we look at together when addressing the impact of stress with clients)

How Nutrition Can Help the Symptoms of Stress

At Longtail Nutrition, we believe in the power of nutrition and lifestyle changes to manage stress. Here are some effective strategies to reduce stress and its impact on your health:

Key Nutrients for Stress Response

Certain nutrients play a vital role in managing the stress response:

Magnesium: Often referred to as nature's tranquilliser, magnesium is crucial during times of stress. Foods rich in magnesium include leafy greens, nuts, seeds, and beans.

B Vitamins: Essential for energy production and nervous system health, B vitamins can help reduce stress. Sources include whole grains, meat, eggs, and dairy products.

Vitamin C: An antioxidant that supports adrenal health and immune function. Citrus fruits, strawberries, and bell peppers are excellent sources.

Omega-3 Fatty Acids: Known for their anti-inflammatory properties, can help lower stress-related inflammation. Omega-3s support brain health and can help balance stress-related symptoms such such as low mood. Include oily fish, flaxseeds, and walnuts in your diet.

Prioritise Sleep

Quality sleep is a cornerstone of stress management. Establish a regular sleep routine, create a calming bedtime environment, and consider natural sleep aids like chamomile tea, epsom salt baths or magnesium supplements.

Exercise Appropriately

Exercise is a potent stress reliever, but it's essential to find the right balance. Overtraining can increase stress, so incorporate restorative activities like yoga and tai chi alongside moderate physical activity. Be mindful of taking rest days for optimal recovery from intense exercise.

Practice Meditation and Mindfulness

Incorporating mindfulness practices and meditation into your daily routine can significantly reduce stress. These practices promote relaxation, improve focus, and enhance emotional resilience.
