When we think about stress, the first thing that comes to mind is its negative consequences, such as anxiety, depression, and chronic diseases. However, not all stress is bad for us. Some types of stress can benefit our health. These types of stress are called hormetic stressors, and they have numerous benefits that help combat metabolic diseases, improve gut health, and promote longevity. This article explores some of our favorite hormetic stressors and the science behind their benefits.
Exercise
One of the most potent hormetic stressors is exercise. When we exercise, we subject our bodies to physical stress, activating various cellular pathways in energy production, metabolism, and immune function. Exercise has numerous benefits, such as improving insulin sensitivity, cardiovascular health, and cognitive function.
Insulin sensitivity is a critical factor in metabolic health, and it refers to the body’s ability to use insulin effectively to regulate blood sugar levels. When we become insulin resistant, our body loses its ability to use insulin effectively, which leads to high blood sugar levels and increases the risk of developing type 2 diabetes and other metabolic diseases. Exercise has been shown to improve insulin sensitivity by increasing the uptake and utilization of glucose by skeletal muscles.
Cardiovascular diseases are the leading cause of death worldwide, and exercise is one of the most effective ways to reduce the risk of developing them. Regular exercise has been shown to improve numerous cardiovascular risk factors, such as blood pressure, cholesterol levels, and arterial function. Moreover, exercise helps reduce inflammation, a crucial cardiovascular disease driver.
Beyond metabolic and cardiovascular health, exercise has numerous benefits for brain health. Physical activity has been shown to improve cognitive function, reduce the risk of dementia and Alzheimer’s disease, and enhance mood and stress resilience. Exercise triggers the release of neurotrophic factors, such as brain-derived neurotrophic factor (BDNF), which promotes brain neurons’ growth and survival.
Cold Exposure
Cold exposure is another potent hormetic stressor that has numerous benefits for our health. When we subject our bodies to cold, we activate various energy metabolism, immune function, and stress response pathways. Cold exposure has been shown to reduce inflammation, enhance immune function, and increase energy expenditure.
One of the most promising benefits of cold exposure is its ability to improve insulin sensitivity. Cold exposure has been shown to increase the uptake and utilization of glucose by skeletal muscles, similar to exercise. Moreover, cold exposure helps activate brown adipose tissue, a fat tissue that generates heat and burns calories. Brown adipose tissue is more prevalent in lean individuals and declines with age and obesity.
Cold exposure also has numerous benefits for immune function. When we expose our bodies to cold, we activate various immune cells, such as natural killer and T cells, which help fight infections and cancer. Moreover, cold exposure helps reduce inflammation, a crucial driver of chronic diseases like metabolic syndrome, cardiovascular disease, and cancer.
Lastly, cold exposure has been shown to enhance energy expenditure by increasing the activity of uncoupling proteins, which are involved in producing heat and burning calories. Cold exposure may be a promising strategy for weight loss and preventing obesity.
Fasting
Fasting is an effective way to induce hormetic stress and promote autophagy, which is the body’s way of cleaning up damaged cells and promoting cellular rejuvenation. When we fast, we subject our body to a state of energy deprivation, which activates various pathways involved in metabolism, cellular repair, and stress response. Fasting has numerous benefits for our health, such as promoting weight loss, improving insulin sensitivity, and reducing inflammation.
Weight loss is one of the most promising benefits of fasting. Reducing caloric intake creates a negative energy balance that leads to weight loss. Moreover, fasting has been shown to increase the activity of brown adipose tissue, similar to cold exposure, which helps burn calories and promote weight loss.
Improving insulin sensitivity is another crucial benefit of fasting. By reducing caloric intake, we decrease the demand for insulin, which helps improve insulin sensitivity. Fasting also stimulates the production of ketones, an energy source for the brain and the muscles. Ketones have been shown to improve insulin sensitivity and reduce inflammation.
Lastly, fasting promotes autophagy, a process of cellular repair and rejuvenation. Autophagy helps the body clean up damaged cells and promotes the growth of new cells. Autophagy has numerous benefits for our health, such as reducing inflammation, promoting cellular rejuvenation, and reducing the risk of chronic diseases.
Sauna Therapy
Sauna therapy is another effective way to induce hormetic stress and promote numerous health benefits. When we expose our body to the heat and humidity of a sauna, we activate various pathways involved in stress response, cardiovascular health, and skin health. Sauna therapy has been shown to reduce stress levels, enhance cardiovascular health, and improve skin health.
Reducing stress levels is one of the most promising benefits of sauna therapy. Exposing our body to heat and humidity activates the production of heat shock proteins, which help the body cope with stress. Heat shock proteins have been shown to reduce anxiety and improve mood, similar to exercise.
Enhancing cardiovascular health is another crucial benefit of sauna therapy. Sauna therapy has improved numerous cardiovascular risk factors, such as blood pressure, cholesterol levels, and arterial function. Moreover, sauna therapy helps reduce inflammation, a crucial cardiovascular disease driver.
Lastly, sauna therapy has numerous benefits for skin health. Exposure to heat and humidity promotes sweating, which helps cleanse the skin of toxins and impurities. Moreover, sauna therapy promotes blood flow and oxygenation to the skin, which helps nourish and hydrate the skin. Sauna therapy has been shown to improve skin texture, reduce fine lines and wrinkles, and improve overall skin health.
Conclusion
In conclusion, hormetic stressors are beneficial to the body, and they have numerous benefits that help combat metabolic diseases, improve gut health, and promote longevity. Exercise, cold exposure, fasting, and sauna therapy are some of our favorite hormetic stressors, and they have been shown to have numerous benefits for our health. Incorporating these hormetic stressors into our lifestyle can promote health and longevity and reduce the risk of chronic diseases.
