Recharging the Mind: Insights from David Co, CEO of Calm on Stress, Battery Analogy, and Workplace Wellness

Introduction

In a recent episode of the On Purpose podcast, host Jay Shetty sits down with David Co, CEO of Calm and author of the new book Recharge. They explore why 61% of people feel pressured to "just get over" stress, how stress can be both a catalyst for growth and a source of burnout, and practical ways to monitor and replenish our mental energy.

The Battery Analogy

• Core concept: Treat your mind like a phone battery. Instead of asking "How are you?" ask "How’s your battery?".
• Why it works: A simple numeric scale (0‑100%) makes the abstract feeling of stress concrete and actionable.
• Four zones:
• 75‑100% – Healthy, moving along.
• 50‑75% – Start planning a recharge.
• 25‑50% – Take a break, walk, put down the phone.
• 0‑25% – Hard stop; urgent need to recharge.

Measuring Stress on a 0‑100 Scale

• Peak moments (100%): Weddings, birthdays, major achievements.
• Low moments (0%): Job loss, bereavement, severe burnout.
• Everyday check‑ins: Like a phone’s battery icon, noticing yellow or red alerts prompts early intervention before hitting zero.

Strategies to Recharge

• Physical movement: Walks, outdoor time, workouts.
• Breath work: Deep breathing exercises to reset the nervous system.
• Sleep hygiene: Keep phones out of the bedroom, maintain consistent bedtime.
• Mindfulness & meditation: Short 5‑15 minute sessions (even during Zoom calls).
• Micro‑breaks: 30‑second silence, “take a breath” prompts.
• Social connection: Time with loved ones, gratitude rituals.
• Nutrition: Balanced meals; avoid late‑night snacking that disrupts sleep.

Good Stress vs. Bad Stress

• Good stress (eustress): Drives resilience, growth, and stronger culture when it’s manageable and purposeful.
• Bad stress (distress): Accumulates when deadlines are nonstop (247/365), leading to anxiety, depression, and physical ailments.
• Leadership role: Recognize when team stress is crossing from eustress to distress and intervene with intentional pauses and support.

Leadership, Vulnerability, and Culture

• Modeling vulnerability: CEOs sharing personal struggles (e.g., David’s childhood anxiety, smoking habit) normalizes open dialogue.
• Creating safe spaces: One‑on‑one check‑ins that focus on well‑being before metrics.
• Transparent goal‑setting: Clearly communicate objectives so employees know the challenge and the support available.
• Rituals at Calm: Daily meditation at all‑hands, gratitude rounds, weekly "wins" sharing, Zoom‑free days, and purposeful meeting design.
• Empowering teams: Involve employees in strategy creation (e.g., company retreats where staff draft the vision).

Practical Tools for Individuals & Teams

• Battery‑check habit: Ask yourself and teammates, "What’s your battery level?" at the start of meetings.
• Zone‑based actions: Follow the four‑zone framework to decide on a walk, a short meditation, or a full day off.
• Digital detox: Designate phone‑free periods, especially during meals and before bedtime.
• Personal rituals: Morning coffee without a phone, opening windows for fresh air, three deep breaths, walking meetings.
• Company‑wide resources: Provide access to apps like Calm, therapy services, and education on mental‑health vocabulary.

Final Reflections

David emphasizes that stress will never disappear, but by reframing it as a battery level, we gain a concrete tool to monitor, communicate, and act on our mental state. Leaders who are present, vulnerable, and intentional can embed these practices into culture, turning stress into a driver of resilience rather than a source of burnout.

Treat your mental health like a phone battery: regularly check the charge, use simple zone‑based actions to recharge, and let leaders model vulnerability and intentional pauses. By doing so, stress becomes a source of growth, productivity rises, and both individuals and organizations thrive.
