Rethinking Stress: Could a Little More Be What You Need?

Have you ever gone through something hard and realized you just weren’t the same afterwards?

Most of us have experienced this after major life events. However, at a cellular and molecular level, this recalibration is happening all the time, with every single stressor we’re exposed to.

This brings me to one of the most important, and often overlooked, aspects of stress: We don’t return to baseline after stress. We emerge with a new one.

Every stressor, whether physical, psychological, or environmental, shifts our set point. While some stressors indeed deplete us, others help us build a higher set point and net resilience.

This is what makes good stress so powerful. The goal isn’t just to bounce back after discomfort; it’s to build toward a higher level of human potential.

This concept is at the heart of hormesis, the fascinating science of how stress, and a lack of it, shapes our health, happiness, and the way we age.

Stress at the Cellular Level

Our stress responses are more complex than a patterned fight-or-flight reaction. When our cells sense stress, they prepare for hard times by shifting their activity from growth to energy efficiency, repair, and maintenance. When we recover, we grow healthier cells and build connections and signals that help us better handle future stress.

Good stressors activate seven key cellular response mechanisms, which control what I call the four R’s:

• Resistance to oxidative and inflammatory stress.
• Repair of DNA, proteins, and mitochondrial function.
• Recycling of damaged and aging cells via autophagy.
• Regeneration of energy systems and damaged tissues.

These mechanisms not only influence our mental and emotional well-being but also play a crucial role in slowing biological aging and reducing the risk of chronic diseases. We have the power to regenerate and repair both our mind and body through simple, everyday habits.

Discomfort at the Right Dose and Duration

It's important to engage your stress systems in a way that fosters growth. Recognizing the “sweet spot” for stress exposure—often referred to as the Goldilocks zone—followed by strategic recovery, allows for effective adaptation. Here are some simple and effective ways to challenge yourself:

1. Eat a Diverse Array of Plants

Plants produce natural compounds called phytochemicals to protect them from stressors such as predation, drought, and UV light. When we consume plants, their phytochemicals gently stress our cells, activating powerful repair pathways like sirtuins and antioxidant enzymes. Make it a habit to include a variety of vegetables, fruits, legumes, and whole grains on your plate.

2. Engage in High-Intensity Movement

Brief bursts of high-intensity effort—like fast walking, cycling, or rowing—burn through energy stores and send a strong stress signal that ramps up your energy-producing cellular engines called mitochondria. They also improve insulin sensitivity and enhance cardiovascular and brain function. The key is providing enough challenge to push your muscles, mitochondria, and metabolism to adapt.

3. Fast in Sync With Your Circadian Rhythm

Going without food for at least 12 hours creates a mild, beneficial stress that activates your cellular housekeeping systems. When you fast in alignment with your circadian clock, stopping food intake a few hours before bed and delaying breakfast slightly in the morning, you give your body time to shift from digestion to repair. This short daily fast lowers insulin, turns off growth signals like mTOR, and stimulates autophagy, a process that clears out damaged cellular components.

4. Expose Yourself to Cold and Heat

Both cold and heat stress activate unique responses that enhance health, metabolism, and cellular repair. Brief exposure to cold, such as a 30-second cold shower or spending time outside lightly dressed, triggers a surge of norepinephrine, which sharpens focus, improves mood, and activates brown fat to burn energy and regulate blood sugar. Conversely, heat from saunas or hot baths raises core temperature and stimulates heat shock proteins, which help repair damaged proteins, reduce inflammation, and protect cells from stress. Aim for regular, manageable exposure that pushes your body just enough to feel uncomfortable but not overwhelmed.

5. Pursue Meaningful Mental and Emotional Challenges

Just like your body thrives on physical stress, your brain needs challenge to stay sharp, resilient, and adaptable. The most powerful mental and emotional stressors are the ones that excite you with the potential for reward, align with your values, and stretch your capacity in a purposeful way. Tackling something meaningful—whether it’s learning a new skill, pursuing a creative goal, advocating for a cause you believe in, or having a vulnerable conversation—activates dopamine, the brain’s motivation and reward signal. Over time, this kind of “just-right” challenge builds new neural pathways, promotes neurogenesis, and enhances your ability to think clearly, creatively, and compassionately under pressure.

Resilience Through Stress

Although it may seem counterintuitive, micro stress-recovery cycles compound over time to increase our biological and psychological resilience. Each aspect supports the other, enabling us to handle challenges more effectively, strengthen our disease defenses, and age better.

These processes are set in motion by discomfort. Our bodies evolved to expect adversity. When we optimize only for comfort, we effectively switch off the cellular systems designed to help us regenerate and thrive.

We need to unlearn the belief that all stress is harmful. Instead of fearing or avoiding discomfort, we can benefit from a mindset that sees hard things as a way to expand our potential for health and happiness.
