Imaginemos que hace 10.000 años nuestro principal factor de estrés era conseguir nuestra próxima comida. Si avanzamos rápidamente hasta el presente, nos vemos abrumados por notificaciones incesantes, plazos implacables y la presión constante de estar siempre “conectados”. No es de extrañar que el 77% de las personas en los EE. UU. experimenten regularmente síntomas físicos causados por el estrés.
Pero ¿qué pasaría si pudiéramos tomar prestada la sabiduría de nuestros antepasados para ayudarnos a manejar el estrés de manera más eficaz? Si reprodujéramos las condiciones ambientales de nuestro pasado, podríamos descubrir la tranquilidad que todos buscamos desesperadamente. Este artículo profundiza en la ciencia del estrés, en cómo el entorno de nuestros antepasados puede haber contribuido a su manejo del estrés y en cómo podemos incorporar algunas de sus prácticas a nuestra vida actual.
La ciencia del estrés y su impacto en nuestro organismo
El estrés es la respuesta instintiva de nuestro cuerpo a las amenazas percibidas. Puede ser tanto beneficioso como perjudicial. Si bien puede mejorar nuestra concentración y nuestras reacciones rápidas en situaciones peligrosas, el estrés crónico puede provocar problemas de salud como dolores de cabeza, insomnio e incluso enfermedades cardíacas.
Curiosamente, nuestro entorno influye significativamente en nuestros niveles de estrés. Por ello, viajemos al pasado y descubramos los factores que ayudaron a nuestros antepasados a mantener la compostura.
Práctica 1: Fuertes conexiones con la comunidad
In ancestral times, human survival depended on close-knit communities. People lived in tribes or small groups where cooperation, shared responsibilities, and constant social interaction were essential. These strong social bonds provided emotional support, belonging, and security.
Conflict resolution happened face-to-face, and people worked together toward common goals like hunting, gathering, and shelter building. This deep-rooted social structure naturally buffered individuals against stress by fostering trust and collective resilience.
In contrast, modern society has become increasingly individualistic. Many live alone, work remotely, and rely heavily on digital communication. Social media and technology, while connecting us superficially, often lack the depth of real-life interactions.
This shift has led to feelings of isolation and loneliness, which are significant contributors to chronic stress. Studies show that social isolation can increase cortisol (the stress hormone) and weaken the immune system, heightening vulnerability to mental health issues.
Rebuilding community connections can reduce this stress. Engaging in local groups, volunteering, or spending quality time with loved ones helps restore the sense of belonging our ancestors naturally had. Strong relationships act as a buffer against stress, improving emotional well-being and physical health, much like they did for our ancestors.
Práctica 2: Acceso a la naturaleza
Our ancestors lived in constant connection with nature. Daily activities like hunting, gathering, and shelter-building required them to spend most of their time outdoors, fully immersed in natural environments.
This regular exposure to fresh air, sunlight, and green spaces supported their physical health and helped them regulate stress naturally. The rhythms of nature—daylight, seasons, and weather—guided their routines, fostering a balanced lifestyle in tune with their surroundings.
Today, modern life often disconnects us from nature. Many people spend most of their day indoors, under artificial lighting, and surrounded by technology. Urban environments, long work hours, and screen time have drastically reduced our interaction with natural spaces.
This disconnection contributes to higher stress levels, mental fatigue, and emotional imbalance. Studies have shown that lack of exposure to nature can increase anxiety and depression while spending time in natural settings lowers cortisol levels and improves mood.
Reintroducing nature into daily life can significantly reduce stress. Simple activities like walking in a park, hiking, gardening, or sitting by water can restore mental clarity and emotional balance. By reconnecting with nature, we can tap into the same stress-relieving benefits our ancestors experienced, promoting overall well-being.
Práctica 3: Exposición a fluctuaciones de temperatura
Our ancestors directly interacted with the natural environment, experiencing daily and seasonal temperature changes without modern climate control. They adapted to cold winters and hot summers through physical activity, layered clothing, and natural shelter, strengthening their resilience to environmental stress.
This constant exposure to temperature fluctuations helped regulate their metabolism, improve circulation, and enhance their stress response.
In contrast, modern living has largely eliminated natural temperature variations. Central heating and air conditioning keep our environments at a constant, comfortable temperature year-round. While this convenience improves comfort, it also reduces our body’s ability to adapt to stressors.
Research suggests that consistent exposure to stable temperatures can weaken the body’s resilience, making us more sensitive to environmental stress and reducing our metabolic flexibility.
Reintroducing natural temperature variations can strengthen stress resilience. Activities like taking cold showers, swimming in cold water, or spending time outdoors in different seasons activate the body’s adaptive stress response.
Cold exposure, for example, can lower inflammation, boost mood through endorphin release, and improve circulation. By embracing natural temperature shifts, we can build physical and mental resilience, like our ancestors, leading to a more balanced and stress-resistant body.
Práctica 4: Dieta más saludable
Our ancestors followed a diet composed entirely of whole, unprocessed foods. They consumed what was naturally available—fresh fruits, vegetables, nuts, seeds, lean meats, and fish. This nutrient-dense diet provided essential vitamins, minerals, and healthy fats that supported optimal brain function, stable energy levels, and a balanced hormonal system.
Without processed sugars, artificial additives, or refined grains, their bodies maintained steady blood sugar levels and a strong immune response, reducing internal stress on the body.
Today’s diet is drastically different. Highly processed foods, sugary snacks, refined carbohydrates, and artificial ingredients dominate many people’s meals. These foods can cause blood sugar spikes and crashes, increase inflammation, and disrupt gut health—all of which elevate physical and mental stress. Additionally, nutritional deficiencies caused by poor diet choices can impair the body’s ability to manage stress effectively.
Returning to a more natural, ancestral-inspired diet can significantly reduce stress. Eating whole, unprocessed foods—such as fresh produce, lean proteins, nuts, seeds, and healthy fats—supports balanced energy, stable mood, and better stress resilience. By nourishing the body with real food, we provide it with the tools to manage stress more effectively, just as our ancestors naturally did.
Práctica 5: Actividad física regular
Physical activity wasn’t optional for our ancestors—it was a necessary part of survival. Daily tasks like hunting, gathering, building shelters, and migrating demanded constant movement. This natural blend of endurance, strength, and mobility exercises kept their bodies strong and their stress levels balanced.
Physical exertion helps regulate stress hormones, boost mood through endorphin release, and improve overall resilience to life’s challenges.
In modern society, physical activity has mainly become optional. Many people work sedentary jobs, commute by car, and unwind with passive entertainment like watching TV or scrolling on devices. This lack of movement can lead to chronic stress, muscle tension, poor sleep, and mental fatigue. Without regular exercise, the body struggles to regulate cortisol levels and manage stress effectively.
Reintroducing regular movement into daily life can significantly reduce stress. This doesn’t mean intense workouts are necessary—simple, consistent activities like walking, stretching, cycling, or dancing can improve mood and lower anxiety.
Physical activity releases endorphins, reduces tension, and improves sleep quality, all of which help buffer against stress. Moving more throughout the day can reconnect with our natural physical rhythms and build the same stress resilience our ancestors enjoyed.
Práctica 6: Respiración controlada
Due to their slower-paced, physically active lifestyles, our ancestors naturally maintained steady and deep breathing patterns. Without the constant mental stimulation and distractions of modern life, they engaged in activities that promoted calm and rhythmic breathing, such as walking, crafting tools, or sitting around a fire. This natural breathing regulates their nervous system, keeping stress responses in check and promoting relaxation.
Chronic stress, multitasking, and digital overstimulation often lead to shallow, rapid breathing. This “chest breathing” activates the sympathetic nervous system (the fight-or-flight response), increasing heart rate and stress hormone production. Over time, this constant state of heightened alertness can contribute to anxiety, fatigue, and poor emotional regulation.
Incorporando controlled breathing exercises helps counteract this modern stress response. Techniques like diaphragmatic, box, or alternate nostril breathing engage the parasympathetic nervous system, promoting relaxation and reducing cortisol levels.
Just a few minutes of mindful breathing each day can improve focus, lower anxiety, and enhance emotional resilience. By intentionally practicing slow, deep breathing, we can restore the natural rhythm our ancestors experienced, creating a powerful tool for managing modern stress.
Práctica 7: Reducir las distracciones
Our ancestors lived in environments with minimal distractions. Their attention was focused on essential tasks like finding food, building shelter, and maintaining social bonds. Without constant interruptions, their minds could stay present and engaged. This mental clarity naturally supported lower stress levels and allowed for proper rest and recovery after periods of activity or challenge.
In contrast, modern life is filled with endless distractions—smartphones, social media, constant notifications, and 24/7 connectivity. This overstimulation keeps the brain in a heightened state of alertness, triggering stress responses even when there’s no real threat. Multitasking, frequent interruptions, and information overload make it harder to focus, leading to mental fatigue, anxiety, and chronic stress.
Reducing these distractions can significantly lower stress levels. Setting boundaries with technology—like turning off notifications, limiting social media use, or scheduling screen-free times—gives the mind space to rest and reset.
Engaging in focused activities, practicing mindfulness, or simply spending quiet time without digital input can improve concentration and emotional well-being. By simplifying our mental environment, we can restore the sense of calm and focus our ancestors naturally had, creating a more peaceful and resilient mind.
Conclusión
El secreto para reducir el estrés puede encontrarse en el estilo de vida sencillo de nuestros antepasados. Al fomentar vínculos comunitarios sólidos, pasar tiempo en la naturaleza, experimentar las fluctuaciones de temperatura, comer alimentos más saludables, realizar actividad física, practicar la respiración controlada y reducir las distracciones, podemos mitigar el estrés y fomentar una vida más pacífica y alegre.
