The Most Overlooked Pillar of Health: Sleep

When it comes to optimizing health, most people focus on diet and exercise. But there’s a third pillar that is often overlooked and yet critically important: sleep.

I’m Micah, a licensed nurse with over 30 years of healthcare experience in hospitals, long-term care, home care, and private duty. Over the years, I have learned—and personally experienced—just how much neglecting sleep can harm your health.

From my experience working long shifts and night shifts, I can tell you that skipping sleep isn’t just about feeling tired. It can lead to serious consequences like weight gain, becoming pre-diabetic, constant fatigue, irritability, and even falling asleep whenever and wherever you can sneak in rest.

Why is sleep so important? Here are three key reasons:

Lower Your Health Risks
Getting enough sleep reduces your risk of developing diabetes, heart disease, and other chronic conditions. Lack of sleep has been linked to obesity, high cholesterol, high blood pressure, and increased risk of accidents—drowsy driving alone causes over a quarter million crashes annually according to AAA. Sleep regulates blood sugar, supports healthy metabolism, and helps maintain heart health.​

Boost Your Mood and Memory
Sleep is crucial for brain function. It helps reduce stress, improve mood, and enhance memory formation and consolidation. Without adequate sleep, your ability to focus, think clearly, and form long-term memories suffers. Studies show that insufficient sleep impairs emotional regulation and is linked to anxiety and depression.​

Make Better Decisions
Whether at school or work, sleep sharpens your focus and decision-making skills. It improves cognitive processing, creativity, and problem-solving abilities. When sleep is neglected, reaction times slow, coordination worsens, and you become prone to mistakes and accidents—sometimes without even realizing it during microsleep episodes.​

Sleep also supports your immune system by boosting your body’s infection-fighting mechanisms and reducing inflammation. Poor sleep dampens immune response making you more vulnerable to illnesses and reduces the effectiveness of vaccines.​

If you want to dive deeper into why sleep is your superpower, I highly recommend watching sleep scientist Matt Walker’s TED Talk, "Sleep is Your Superpower." He explains how sleep is Mother Nature’s ultimate life-support system and reveals fascinating insights on how sleep influences everything from memory to genetics. You can watch it here:

Your health truly is your power, and sleep is a vital key to unlocking it. Don’t underestimate the importance of restful, consistent sleep alongside diet and exercise for achieving optimal wellness.
