In today’s fast-paced digital world, Mental Health has become a crucial topic for individuals and organizations alike. We often feel overwhelmed, burnt out, or drained, yet many of us are told to simply “get over” stress and power through. But what if there was a better way to understand and manage our stress? What if we could check in with ourselves and others in a meaningful way that goes beyond the usual “How are you?” and actually helps us recharge our mental batteries?
Drawing from deep experience and insights shared by David Ko, CEO of Calm and author of Recharge, this article explores the groundbreaking analogy of the brain as a phone battery and offers practical, science-backed strategies to boost your mental health. Whether you’re feeling stressed, drained by work, or struggling to find balance, this guide will help you understand good versus bad stress, the importance of vulnerability in leadership, and how to create a culture of mental wellness both at home and in the workplace.
Why Your Brain Is Like a Phone Battery Mental Health
One of the most powerful concepts David Ko shares is that our mental energy functions much like the battery on a smartphone. We process an astonishing amount of information daily—about 72 gigabytes, comparable to reading Tolkien’s The Hobbit every single day. No wonder many feel mentally overloaded.
Ko’s friend introduced a simple but transformative question: “How’s your battery?” Unlike the usual “How are you?” which often gets a robotic “fine” in response, asking about battery life invites a more honest and tangible check-in. People, including children, can easily relate to the idea of monitoring their energy levels in percentages, such as 75%, 50%, or 25% battery remaining.
This analogy helps simplify mental health into manageable zones:
- 75% to 100%: You’re feeling good and moving along smoothly.
- 50% to 75%: You might need to start thinking about ways to recharge.
- 25% to 50%: It’s time to take a break, maybe go for a walk or unplug from digital distractions.
- 0% to 25%: A hard stop is needed; you must prioritize recharging to avoid burnout.
By framing mental health in this way, it becomes easier to recognize when you’re running low and take proactive steps to restore your energy.
How to Recharge Your Battery: 9 Effective Practices
Recharge isn’t about just resting; it’s about consciously powering up your mental battery. Everyone is different, but here are nine science-backed ways to recharge effectively:
- Sleep Well: Sleep is the foundational charger. Poor sleep leads to irritability and reduced productivity. Prioritize quality sleep by limiting device use before bed and creating a restful environment.
- Meditate and Practice Mindfulness: Calm and similar apps offer guided meditations that help reduce stress and improve focus. Even a few minutes daily can reset your mind.
- Exercise Regularly: Physical activity boosts your mood and energy. David Ko emphasizes daily movement, whether at the gym or a quick home workout.
- Take Breaks and Walk: Short breaks during work, especially walking meetings or time outdoors, help clear mental clutter and recharge your focus.
- Practice Gratitude: Ending meetings or days by sharing gratitude fosters positive mental states and strengthens team bonds.
- Limit Digital Overload: Avoid constant phone checking, especially during meals or family time. Designate phone-free moments to enhance presence.
- Connect with People: Spending time with loved ones or supportive colleagues recharges emotional batteries.
- Set Boundaries: Learn to say no to unnecessary meetings or social plans that drain you, and prioritize quality over quantity in your schedule.
- Reflect and Self-Assess: Regularly ask yourself, “How’s your battery?” and identify what activities drain or restore your energy.
The Role of Vulnerability and Leadership in Mental Health
One of the critical insights from David Ko is the importance of vulnerability, especially among leaders. Many CEOs feel pressure to appear strong and worry that showing vulnerability might be perceived as weakness. However, true strength lies in being authentic and open about mental health challenges.
Leaders who share their own struggles create a safe space for employees to do the same. This openness fosters trust, improves communication, and builds a resilient culture. Ko shares how at Calm, leadership starts meetings with meditation and ends with gratitude, setting a tone of presence and care.

Moreover, leaders who involve their teams in decision-making empower employees and reduce stress caused by unclear goals or overwhelming expectations. By providing clear goals and support, leaders enable their teams to focus on challenges productively rather than feeling lost or unsupported.
Good Stress vs. Bad Stress
Stress is often seen as negative, but not all stress is bad. Ko explains the difference:
- Good Stress (Eustress): This type of stress motivates, builds resilience, and drives growth. It’s the push that helps you meet deadlines and achieve goals.
- Bad Stress (Distress): Excessive, chronic stress leads to anxiety, depression, and physical health problems. It hampers productivity and damages workplace culture.
Understanding this spectrum helps individuals and organizations manage stress more effectively by aiming to maintain good stress levels while minimizing distress.
Building a Culture That Supports
Despite growing awareness, mental health conversations often stop at the workplace door. Ko emphasizes the need to normalize mental health discussions in professional settings just as much as in personal life.
Companies can support mental health by:
- Providing accessible mental health tools like meditation apps and therapy options.
- Creating rituals such as Zoom-free days or gratitude sharing to reduce burnout.
- Polling employees regularly to understand their needs and preferences.
- Encouraging leaders to be vulnerable and transparent about their own mental health journeys.
Such steps help employees feel valued and supported, which boosts loyalty, productivity, and overall well-being.
Listening as a Leadership Superpower
Great leaders are great listeners. Former Apple CEO John Sculley famously called himself the “Chief Listening Officer,” emphasizing that listening carefully and speaking less can lead to better decisions and stronger teams.
Listening with intention allows leaders to understand what’s draining their team’s batteries and address those issues thoughtfully. It also helps in identifying when someone is at a critical low battery level and needs support before burnout occurs.
Why Mindfulness and Meditation Help Burnout and Productivity
Mindfulness and meditation are more than just trendy practices—they have a solid scientific basis for improving mental health and workplace performance.
Many Calm users, for example, come to the app for help with sleep, which is often disrupted by stress and digital distractions. Better sleep fosters better mood, sharper focus, and higher productivity.
During the day, taking mindful breaks helps reset the brain’s limited capacity, preventing mental fatigue. Ko points out that trying to push through low battery moments without recharging results in subpar work and poor decision-making.
Conversely, a still and rested mind makes quicker, clearer decisions, communicates better, and is more patient and tolerant—qualities essential for both personal and professional success.

Practical Tips for Maintaining Your Mental Battery
Here are some actionable tips you can start implementing today to monitor and maintain your mental health battery:
- Ask “How’s your battery?” instead of the generic “How are you?” to encourage honest self-assessment.
- Track your energy levels daily and notice patterns related to work, social life, and rest.
- Develop morning rituals such as deep breathing, opening a window for fresh air, or making coffee mindfully.
- Use walking meetings to integrate movement and fresh air into your workday.
- Turn off devices during meals and family time to be fully present.
- Say no to non-essential meetings and prioritize quality interactions over quantity.
- Practice gratitude regularly to foster positive emotions and connection.
- Find your unique recharge methods—whether it’s exercise, meditation, nature, or social connection.
The Future of Mental Health Conversations
As mental health becomes more approachable, especially among younger generations, organizations and leaders have a responsibility to keep pace. Providing mental health resources and fostering open dialogue is no longer optional but essential for sustainable success.
Ko advocates for integrating mental health education early in life, much like physical education, to equip children with the vocabulary and tools to manage stress healthily from a young age.
Ultimately, mental health is about powering up your battery to live a happier, healthier, and more productive life. By embracing vulnerability, practicing mindfulness, and creating supportive environments, we can transform how we experience stress and burnout.
Conclusion: Recharge to Thrive Mental Health
The analogy of your brain as a phone battery offers a simple yet profound framework for understanding mental health in today’s complex world. Recognizing when your battery is low and knowing how to recharge with personalized strategies can prevent burnout and enhance your overall well-being.
Leaders play a pivotal role by modeling vulnerability and creating cultures that prioritize mental wellness. Through active listening, clear communication, and intentional decision-making, they can foster environments where good stress motivates and bad stress is minimized.
Remember, mental health is not about just powering through but about powering up. Start by asking yourself and those around you, “How’s your battery?” and take the steps needed to recharge. Your productivity, relationships, and happiness depend on it.
“You are only as good as your team. Being a leader means taking care of your team—being a coach, therapist, and support system all in one.” — David Ko
