The Cortisol Connection: Managing Stress in a Season of Panic


Stress is a condition of mental, physical, or emotional strain brought on by challenging or unpleasant circumstances. High stress levels are associated with overproduction of the hormone cortisol, which can have detrimental effects on both the body and the mind. In “The Cortisol Connection,” Shawn Talbot describes how stress (“what you feel when life’s demands exceed your ability to meet those demands”) can cause blood levels of cortisol to rise excessively. There is little point in dieting or exercising to prevent weight gain and disease unless levels of this hormone are controlled. In the book, methods for reducing cortisol to ranges that are beneficial for good health are discussed.

The Physiology of Stress

As a defense mechanism against danger, the body produces stress. A complex hormonal mixture is released into the bloodstream in response to the feeling of fear or a perceived threat to one’s safety, status, or well-being, putting the body into “fight or flight” mode. Anxiety, irritability, insomnia, digestive issues, and depression are examples of stress-related symptoms. Additionally, chronic stress depletes the immune system, making a person more susceptible to illness, and shuts down the brain, making it difficult to focus and making bad decisions. One of the key hormones related to stress is cortisol, which works on the brain to regulate emotions like fear and motivation. It has positive effects at normal levels, but when levels rise too high, it can lead to unhealthful weight gain, high blood pressure, and immune system deficiencies.

Stress benefits

In daily life, cortisol can and often does have a positive impact. The daily act of waking from sleep is closely followed by an increase in cortisol levels to provide energy for the demands of the day, and another boost in the late afternoon provides second wind. In moderate amounts, it regulates alertness, relaxation, and activity levels. Cortisol levels also temporarily increase in response to enjoyable and exciting experiences, such as children’s and adults’ excitement over birthday presents or activities like rock climbing. Many people perform better under stress due to an increase in brainpower, which also fosters resilience and, at least temporarily, raises immunity to pathogens.

Chronic Stress: causes and consequences

The causes of chronic (ongoing) stress are numerous and highly individual; what stresses out one person may relax another. Bereavement, unemployment, and lack of sleep, however, are some fairly common causes of negative stress. In addition to the other difficulties of life, a body that is under constant stress produces cortisol levels that are higher than usual. Additionally, cortisol-induced stress-related weight gain is linked to the onset of diabetes, heart disease, and cancer, and tends to concentrate around the abdomen. But it doesn’t stop there; cortisol secretion rises with age, which explains why most people gain weight as they age and why people who are under a lot of stress struggle to lose weight even when they exercise compared to those who are relatively less stressed. To top it all off, elevated cortisol levels can directly affect the brain, causing forgetfulness and hastening the onset of diseases like Alzheimer’s disease in addition to causing disease and hastening the aging process.

Consequently, reducing or even eliminating stress triggers that initially lead to excessive cortisol increases appears to be the best way to prevent weight gain and other health issues. It turns out that stress-relieving techniques, consistent exercise, and healthy eating can reverse the negative effects of chronic stress (even in people who are close to 100 years old). In a perfect world, everyone would get at least eight hours of sleep every night, commute to work only briefly, work no more than seven hours per day, and have plenty of free time. However, the author provides this book as a guide for those who live in the real world to help them get through challenging circumstances and maintain a state of good health.

Remedies for chronic stress

The breadth and diversity of its references, which include 15 books and nearly 300 journal article citations current at the time of publication – a useful compendium in and of itself – show the depth and breadth of the research that went into the creation of this book. Supplements that affect cortisol levels, metabolism, relaxation, and stress reduction are covered in separate chapters. Additionally, a list of popular dietary supplements to stay away from is provided, along with explanations of their unfavorable long-term effects. Daily meal plans and a sizable bibliography are included in the appendix. But it’s unfortunate that the author emphasizes the role of supplements more so than the roles of diet and exercise.

The role of food

The fact that food is meant to be consumed in its natural environment, where the various nutrients can interact in ways that are most suitable for good health, presents one issue with food supplementation. For instance, an orange has about 70 milligrams of vitamin C, but this vitamin is also found in a matrix of fiber that supports bowel health, as well as vitamin A, some B vitamins, calcium, magnesium, and a small amount of energy (about 50 calories). The typical vitamin C supplement contains an excessive amount of the vitamin (typically 1000 mg) on its own, no fiber, and a number of fillers, sweeteners, binders, and other potentially harmful additives. Numerous studies, including a recent randomised controlled trial, have demonstrated that making healthy dietary changes alone can effectively improve mental health even in cases of clinically diagnosed depression. Results are even more astounding when consistent exercise is added to the dietary changes.


It is common knowledge that eating well, exercising more, and reducing stress can all help you stay healthy. By reducing cortisol levels, The Cortisol Connection explains how to optimize both physical and mental health. It details a number of instances where cortisol-lowering supplements have produced favorable outcomes in prose that is understandable to laypeople. Studies show that most people can effectively reduce their cortisol and stress levels by eating the right kinds of foods in the right amounts without going broke. Nevertheless, this book may provide helpful advice on how to manage any resulting stress in today’s climate of increased uncertainty and vulnerability regarding interactions at work, with family, and in social settings.
