The influence of emotions on the body's physiological regulation

In situations of conflict or high emotional load, the body tends to respond automatically. Breathing can quicken, muscles tense up and the heart rate increases. These responses result from the activation of involuntary physiological mechanisms, mediated by the autonomic nervous system, which regulates vital functions such as breathing, heartbeat and blood vessel control, beyond conscious control.

Emotions such as anger, when they arise in a timely manner, appropriate to the context and proportional to the situation, can play an adaptive role. In these cases, they function as preparation and protection responses, helping the organism to deal with situations perceived as demanding or threatening, by activating alert systems.

The relationship between mind and body throughout history

The link between mind and body has been recognised since ancient times. In Ancient Greece, Socrates already questioned the tendency to treat the body in isolation, arguing that understanding illness required considering mental and emotional aspects as well. Despite this initial vision, Western medicine developed for centuries with a focus mainly on the physical body, leaving emotional factors in the background.

It was mainly during the 20th century that this separation began to be questioned. Advances in scientific research showed that psychological and physiological processes are deeply interconnected, contributing to more comprehensive models for understanding health, illness and the body's ability to adapt.

Emotions and health: contributions from scientific research

Over the course of the 20th century, scientific research began to pay more attention to the influence of emotions on physical health. Early studies, including research carried out at Harvard University in 1939, showed that emotional states interact with biological factors and the context of life in the processes of health and illness.

The development of psychoneuroimmunology has helped to deepen this understanding by systematically studying the communication between the nervous system, the endocrine system and the immune system. The work of Hans Selye, who described the body's response to stress, and Robert Ader, who demonstrated the link between psychological processes and the immune response, were fundamental in consolidating this area. More recently, Leo Pruimboom, founder of Clinical Psychoneuroimmunology, contributed to the clinical application of this knowledge by integrating lifestyle factors, the environment and adaptive capacity into the understanding of the body's regulation.

At the same time, the work of Portuguese neuroscientist António Damásio has clearly shown that mind and body work in an integrated way. His research has shown that emotions play a central role in regulating the body and in decision-making processes. These contributions helped to clarify the relationship between body, mind and emotion, reinforcing the idea of the human being as an integrated system that is constantly adapting.

The human being as a biopsychosocial system

From an integrative health perspective, the human being is understood as a system in which biological, psychological and social factors interact continuously. Situations of stress frequent or prolonged can lead to the repeated activation of physiological responses which, when there is no time or conditions for recovery, tend to contribute to states of body overload.

Emotions such as anger, frustration or sadness, when they last for long periods or are not recognised, can be associated with changes in the immune response, mild and persistent inflammatory processes and a lower capacity to adapt. These effects become more relevant when combined with other factors such as little sleep, a sedentary lifestyle or high daily pressure.

How emotions influence the functioning of the body

Emotions influence the body through well-known pathways in the nervous and hormonal systems. When faced with emotionally significant stimuli, areas of the brain involved in emotional processing activate the autonomic nervous system and the neuro-endocrine system, leading to physical responses adjusted to the situation.

One of the main mechanisms involved is the hypothalamic-pituitary-adrenal axis, which is responsible for coordinating the response to the stress. Its activation leads to the release of hormones such as cortisol, which influence metabolism, inflammation, the immune system and cardiovascular function.

These responses are useful when they occur on a one-off basis. However, when they recur frequently or continue for long periods, they can contribute to changes in the body's normal regulation over time, reflecting the continuous interaction between the nervous, hormonal and immune systems.

The relationship between emotional states and physical manifestations

The relationship between emotions and health is not always immediate or easy to identify. Depressive states, for example, can be associated not only with mood swings, but also with persistent tiredness, difficulty sleeping well, greater vulnerability to infections and lower physical endurance. These manifestations reflect the close connection between the emotional, neurological and physiological systems.

In these cases, physical symptoms can appear as indirect signs of wider imbalances, requiring a clinical assessment that goes beyond analysing complaints in isolation.

The role of Clinical Psychoneuroimmunology in understanding emotions

Clinical Psychoneuroimmunology is a scientific area that studies, in an integrated way, the relationship between the nervous system, the endocrine system and the immune system, as well as how these systems influence the functioning of the organism. It assumes that these systems are in constant communication and act together in the processes of adaptation and maintenance of physiological balance.

This approach sees health as the result of the interaction between different systems in the body. Therefore, the functioning of the body cannot be fully understood without considering the link between biological processes, emotional states and life context factors such as the environment, relationships and behaviour. The research that underpins Clinical Psychoneuroimmunology integrates contributions from areas such as neuroscience, immunology and endocrinology, making it possible to understand how the body functions. stress, emotions, sleep, diet and lifestyle influence the body's responses over time.

In a clinical context, Clinical Psychoneuroimmunology seeks to go beyond the identification of isolated symptoms, integrating biological, emotional and contextual aspects to understand the mechanisms associated with states of functional imbalance and support a more balanced regulation of the organism.

Emotions from an integrative perspective

Understanding the link between emotions and physiology is relevant to health promotion and disease prevention. Recognising that emotional states influence the functioning of the body makes it possible to adopt more integrated clinical approaches, which take into account not only physical symptoms, but also the emotional, relational and environmental context of each person.

At Integrative Osteopathy, we work with an integrated and complementary approach, based on the principles of Clinical Psychoneuroimmunology. This area of knowledge studies the interaction between the nervous, endocrine and immune systems, as well as how emotional, behavioural and environmental factors influence health and the body's adaptive capacity.

The clinical assessment seeks to understand the person as a whole, integrating physical symptoms, emotional patterns, levels of stress and lifestyle habits, with the aim of supporting natural self-regulation mechanisms and promoting greater functional balance over time.

Through this approach, we aim to help each person develop greater awareness of their body and its responses, providing tools that favour a healthier life, more balance and a better quality of life.
