Sleep: Your Superpower for Peak Performance

In today’s fast-paced world, sleep is often overshadowed by a culture that glorifies busyness. As a health coach and general manager, I’ve seen firsthand how sleep deprivation can affect both personal well-being and professional performance. Warren Zevon’s quote, “I’ll sleep when I’m dead,” epitomises a mindset that prioritises productivity over rest. Many of us have endured sleepless nights, wearing our fatigue like a badge of honour, but research shows this can damage our well-being.

One of my favourite neuroscientists, Dr Andrew Huberman, says, “Sleep is the foundation of mental health, physical health, and performance of all kinds.” Quality sleep boosts immune function, weight management, memory, and learning. In short, everything improves when we’re well-rested.

Matthew Walker, a renowned sleep researcher, notes that if sleep weren’t essential, evolution would have phased it out. Given our vulnerability while asleep, it’s remarkable how much of our lives we dedicate to it.

Compelling Sleep Statistics

• Leadership Impact: CEOs who don’t sleep enough are perceived as less charismatic, which can negatively affect workplace dynamics.
• Health Consequences: Poor sleepers take about 10 more sick days annually than their well-rested peers.

My Sleep Journey:

Weight Loss

I’ve struggled with diets and weight loss for as long as I can remember. Little did I know that during sleep, the hormones that regulate hunger (“ghrelin”) and satiety (“leptin”) reset and balance. This helps you make better food choices after a restful night, reducing cravings for unhealthy, high-calorie foods. Additionally, the growth hormone released during sleep uses fat for energy, enabling you to burn fat while you sleep!

Muscle Growth

I used to think that pushing myself in the gym was all that mattered, but I’ve learned that sleep is just as important. The release of growth hormone at night is essential for muscle growth and repair. If you’re considering sacrificing sleep for a workout, think twice; adequate sleep is vital for muscle recovery and overall performance!

Ageing

I’ve spent a small fortune on skincare products that promise to reduce wrinkles, but no face cream can compete with a good night’s sleep. Deep sleep promotes collagen production and cellular repair, which are critical for maintaining youthful skin.

Learning and Performance

I used to stay up late preparing for presentations, thinking it would improve my performance. However, research shows that sleep deprivation harms attention, problem-solving, and critical thinking. Without enough sleep, the brain struggles to absorb and retain new information, leading to poorer performance.
