In recent years, deliberate cold and heat exposure has gained traction as a means to improve health and well-being. Dr. Susanna Søberg, a leading researcher in this field, has conducted extensive studies on how these practices can enhance metabolism, hormone regulation, and overall health. In this blog post, we will delve into the insights and findings from her research, highlighting the importance of proper protocols and the physiological mechanisms at play.

Understanding Deliberate Cold Exposure
Deliberate cold exposure refers to intentionally using cold temperatures, such as ice baths or cold showers, to elicit physiological responses that benefit health. Dr. Søberg emphasizes the significance of understanding how our body reacts to cold and the potential benefits of incorporating cold exposure into our routines.
Physiological Responses to Cold
When the body is exposed to cold, physiological responses are triggered. The sympathetic nervous system is activated, releasing catecholamines such as dopamine, norepinephrine, and epinephrine. These neurotransmitters play a crucial role in regulating mood and metabolism.
Dr. Søberg explains that the perceived discomfort of cold exposure is vital to the experience. Initially, entering cold water can feel shocking, but over time, individuals can adapt to the cold, leading to increased resilience and improved metabolic responses.
The Role of Brown Fat
Brown fat, or brown adipose tissue, is a metabolically active type of fat that plays a key role in thermogenesis. Unlike white fat, which stores energy, brown fat burns calories to generate heat. Dr. Søberg's research has shown that cold exposure activates brown fat, improving metabolism and increasing energy expenditure.
Mechanisms of Brown Fat Activation
When cold receptors in the skin are stimulated, signals are sent to the hypothalamus, prompting the activation of brown fat. This process not only helps maintain body temperature but also enhances energy expenditure. Studies have shown that cold exposure can increase energy expenditure by up to 15% due to brown fat activation.
Dr. Søberg's findings highlight the importance of incorporating cold exposure into our routines to harness the benefits of brown fat activation. Gradually acclimating to colder temperatures can improve metabolic health and overall well-being.
Protocols for Cold and Heat Exposure
To maximize the benefits of deliberate cold and heat exposure, Dr. Søberg recommends specific protocols. Her research suggests that individuals should aim for 11 minutes of cold exposure per week, divided into shorter sessions of 1-2 minutes each. For heat exposure, the goal is 57 minutes per week, split into 10-15-minute sessions.
Ending on Cold: The Søberg Principle
One of the most intriguing aspects of Dr. Søberg's research is the "Søberg Principle," which posits that individuals should end their cold exposure sessions on a cold note. This practice forces the body to generate heat independently, effectively training the system to become more efficient at thermoregulation. By doing so, individuals can enjoy prolonged benefits, including improved metabolism and enhanced mood.
Gender Differences in Cold Exposure
Dr. Søberg's research also indicates notable differences in how men and women respond to cold exposure. Women may require less cold exposure to achieve similar benefits than men, potentially due to differences in metabolism and brown fat activity. This finding underscores the importance of personalizing cold exposure protocols based on individual characteristics.
Considerations for Children and Vulnerable Populations
Caution is advised for children and individuals with smaller body sizes. Dr. Søberg stresses the importance of monitoring exposure time and gradually introducing cold exposure. Children may be more susceptible to hypothermia, so it's crucial to approach cold exposure carefully.
Heat Exposure and Its Benefits
In addition to cold exposure, Dr. Søberg explores the benefits of heat exposure, particularly through sauna use. Heat exposure has been linked to numerous health benefits, including improved cardiovascular health and enhanced mood. The mechanisms behind these benefits involve the production of heat shock proteins that protect cells from damage and promote overall cellular health.
Sauna Protocols for Health
Dr. Søberg recommends regular sauna use at least 4-7 times per week to reap the maximum health benefits. Like cold exposure, sauna sessions should be structured to optimize the physiological responses. A typical sauna session should last 10-15 minutes, effectively activating heat shock proteins and other beneficial processes.
Conclusion: Embracing the Cold and Heat
Deliberate cold and heat exposure offers powerful tools for enhancing health and well-being. Dr Susanna Søberg's research provides valuable insights into the physiological mechanisms and protocols that can be followed to achieve optimal results. By embracing the discomfort of cold and heat, individuals can unlock numerous health benefits, from improved metabolism to enhanced mood and resilience.
As we continue to explore the science behind these practices, it is clear that incorporating deliberate cold and heat exposure into our lives can lead to a healthier, more balanced existence. Whether through cold plunges, ice baths, or sauna sessions, the potential for positive change is within reach.
