I am going to be honest with you about something before I write another word of this.
I have bad sleep habits.
Not catastrophic ones. But I know I stay up too late. I know I have a hard time putting my phone down before bed, even when I know I should. I know the TV goes on longer than it needs to. And I know I am not alone in this, because when I look around at the people I know, the people I have worked with, the audiences I write for, this is one of the most universal health struggles there is.
So I am not writing this from a place of having it figured out. I am writing it from a place of understanding exactly what is at stake, and wanting you to understand it too.
Because once you do, things change.
The Setup: We Live in a World That Fights Sleep
Think about a typical night for a lot of people. Work runs late. You finally sit down after dinner. The phone is in your hand before you even think about it. There is always one more thing to scroll through, one more episode to watch, one more message to check. Before you know it, it is midnight. Or later. And the alarm is set for six.
This is not a personal failure. It is the predictable result of living in a world designed to keep you awake and engaged at all hours. Notifications are engineered to trigger your attention. Content is designed to keep you watching. Screens emit blue light that suppresses melatonin secretion in the brain and disrupts circadian rhythm, ultimately reducing sleep quality and duration. (Chronobiology Medicine, 2024) Your body was built to read the absence of light as a signal to wind down. Every screen you look at in the hour before bed sends the opposite signal.
A large cross-sectional study of over 122,000 US adults found that daily electronic screen use before sleep was associated with 48 fewer minutes of sleep per week and a 33% higher prevalence of poor sleep compared with those who reported no screen use. (JAMA Network Open, 2025)
Forty-eight fewer minutes per week does not sound catastrophic. But multiply that over months and years, and you are talking about a significant and compounding sleep debt that your body is carrying silently.
And then there is the bigger picture. Low socioeconomic status is significantly associated with poor sleep continuity and quality, driven by higher stress levels, financial insecurity, shift work, and living in crowded or noisy environments. (Journal of Clinical Sleep Medicine, 2023) If you are working two jobs to make ends meet, dealing with the chronic stress of financial hardship, or living in a loud or unsafe neighborhood, getting eight hours of quality sleep is not just a habit problem. It is a structural one. The people who can least afford poor health outcomes are also the ones most likely to experience them because of inadequate sleep.
This matters because it means the conversation about sleep cannot just be about what time you put your phone down. For many people, real forces make good sleep harder to access. And those forces deserve to be named.
The Conflict: What You Do Not Know About What Is Happening Inside Your Body
Here is where most people check out because they think they know the stakes. You feel tired. You are less productive. You are a little moody. Fine.
But that is the surface. What is happening underneath is the part worth understanding.
While you sleep, your brain is doing something remarkable. It cycles through stages of deep sleep during which it essentially clears out the metabolic waste that accumulated during the day, including proteins associated with cognitive decline. Your heart rate slows. Your blood pressure drops. Your body enters a genuine recovery state that cannot be replicated by lying on the couch watching television or taking a 20-minute nap.
When you consistently cut that process short, the downstream effects are not subtle.
Sleep deprivation elevates cortisol levels, contributes to insulin resistance, drives chronic inflammation, impairs endothelial function, and disrupts the balance between the sympathetic and parasympathetic nervous system, all of which are direct drivers of cardiovascular disease. (Spandidos Publications, 2023) Your blood pressure goes up. Your blood sugar regulation gets worse. The same chronic inflammation that drives heart disease and type 2 diabetes gets amplified. And it all happens quietly, without symptoms, over months and years.
Poor sleep does not just affect you. It affects the people around you. It affects your performance at work, with real consequences for your livelihood and the people who depend on you. It affects your reaction time behind the wheel. It affects your patience with your kids. It affects the quality of every interaction you have on a day when you are running on five hours.
And here is the part that gets to me as a public health professional. Sleep deprivation is one of the most preventable contributors to chronic disease we have. It does not require money to fix. It does not require a doctor visit. It does not require a supplement or a program. It requires a decision, and some information that most people have never been given in a way that actually landed.
The Funny Truth Nobody Says Out Loud
You know who has this figured out? Old people.
I mean that with complete respect. Your grandparents who are in bed by nine, reading a book under a lamp, no phone in sight, alarm set for six AM, waking up refreshed while you are scrolling into the abyss at midnight. They are right. They figured it out before the research confirmed it, and before every tech company in the world started competing for their attention at eleven PM.
The habits we grew out of in our twenties, because they seemed boring, are actually the ones that protect our health. Early to bed. Consistent schedule. No screens right before sleep. A wind-down ritual that gives your nervous system a chance to shift gears.
Our grandparents were not uncool. They were just sleeping.
The Resolution: What You Can Actually Do
You do not need a perfect sleep hygiene routine. You need to move in the right direction.
The most impactful changes are also the most practical:
Set a consistent bedtime and wake time, even on weekends. Your body runs on a circadian rhythm, and consistency is the single most powerful way to regulate it. Irregular sleep schedules are independently associated with higher cardiovascular disease risk. (Frontiers in Sleep, 2025) Your body wants predictability. Give it that.
Put your phone somewhere other than in your hand for the last hour before bed. Not necessarily in a different room, just not in your hand. The issue is not just the blue light. It is the stimulation. A news feed or a social media scroll keeps your brain in an activated state at exactly the moment it needs to be winding down. A book, a conversation, stretching, anything that does not involve a screen, gives your melatonin cycle a chance to do its job.
Make your bedroom a recovery environment. Cool, dark, and quiet are the three things sleep research consistently points to. Blackout curtains, a fan for white noise if your environment is loud, and a temperature that trends cooler rather than warmer.
If you are dealing with chronic stress that is keeping you awake, that is a real barrier, and it deserves real support. Managing the nervous system is something I cover in depth elsewhere, and it is also exactly what The Reset Compass was built to help with. Sometimes the most useful thing you can do before bed is take one small action that brings your nervous system down from an elevated state.
The Punchline
Here is what I want you to take from this.
Sleep is not a reward for finishing your to-do list. It is not a luxury for people who have time for it. It is a biological requirement that your body needs to function, heal, and protect itself from the chronic diseases that are quietly killing more Americans than anything else.
The version of you that is well-rested is more productive, more patient, more present, and physiologically protected in ways that no supplement or workout can replicate. Sleep is the foundation on which everything else sits.
Your grandparents were right. Start going to bed earlier. Put the phone down. Let your brain clean itself.
It sounds boring. It is also one of the most powerful things you can do for your health.
