Day 15 Update: My 21-Day Sleep Challenge Adventures

For years, I’ve been coaching people on sleep, writing about it, and preaching the importance of good sleep hygiene. Personally, I’ve gotten much better at it.

I understand the value of movement, hydration, fresh air, and recognizing what my body needs to wind down. I know that sleep isn’t just about bedtime—it’s a 24-hour cycle, starting with habits, mindset, and energy management throughout the day. I talk about this constantly, but there was one habit that I couldn’t kick no matter how much I tried: sleeping with my phone next to my bed.

I tried everything. I’d put the phone in a drawer, on a dresser, or even tried turning it off entirely overnight. Sometimes I lasted a night or two, but inevitably, I failed. I would tell myself, “It’s fine, it’s just a quick peek at messages,” or “It’s 6 a.m., it doesn’t count as the middle of the night,” and suddenly I’d be scrolling again.

Over time, I realized that my brain had learned a pattern: wake up → reach for phone → stimulation. Breaking that habit wasn’t just about willpower—it required strategy, patience, and a bit of humility.

So, I launched my 21-day phone-free sleep challenge. And here’s the twist: this time, I think it might actually work because of accountability. Knowing I’d be sharing updates publicly, I couldn’t bear the thought of posting that I failed. That little bit of pressure made a huge difference, pushing me to actually follow through.

I have to admit, I’m a little nervous about what will happen after the 21 days. Will I sneak it back into my room? Will I need a new challenge to maintain my independent sleep habits?

Any suggestions are welcome!

Keep reading, and I’ll continue to share updates as I go.

1️⃣ Sleep Feels Deeper Than Ever

The first thing I noticed was how deeply I slept. Nights that I would normally toss and turn, waking multiple times, became nights of consistent, restorative sleep. I used to assume that my waking through the night was just part of getting older, but it turns out my phone was the culprit.

Even if you don’t actively check your phone in the night, just having it nearby creates subtle disruptions. Your brain is subconsciously aware of its presence, alert to notifications, and primed for stimulation. Removing the phone allowed my mind to truly settle. I slept more deeply, woke up feeling more rested, and even my dream recall felt clearer, a sign that my sleep cycles were stabilizing.

This experience reinforced something I always tell clients: sleep quality isn’t just about what you do at bedtime, it’s about setting up your environment to support uninterrupted rest.

2️⃣ Out of Sight, But Not Out of Mind

After a week of removing the phone from my room entirely, I thought I could take a shortcut: leave it in a drawer in the bedroom. Surely, I reasoned, if it’s not visible, I’ll be fine. Wrong. Just knowing it was nearby kept my brain slightly alert. I found myself anticipating the temptation, imagining what I’d check, and even waking slightly more aware than before.

This taught me a critical lesson about habit and environment. Out of sight isn’t always out of mind. Habits tied to strong neurological patterns, like reaching for your phone in the night, need physical separation to break the automatic response. By moving my phone entirely out of the bedroom, I created a clear boundary that my brain could recognize: wake-ups don’t require the phone for stimulation. Small changes in your environment can create huge psychological impact, which is key when retraining ingrained habits.

3️⃣ Morning Rationalizations Are Wild

One morning, when my phone was still in the room, I rushed out of bed to grab it, telling myself: “Might as well get a head start on the day.” It was amazing to see how easily our brains can justify almost anything. We rationalize, twist logic, and convince ourselves that wacky behavior is reasonable.

After that experience, I made a new rule: no phones in bed, no exceptions, no matter the time. Boundaries aren’t just restrictions, they’re a framework for the brain to learn new behaviors. This small change has taught me that self-awareness is a superpower. By noticing how quickly I rationalized reaching for my phone, I was able to pause and adjust, setting the stage for better habits.

4️⃣ Surprise Texts Show the Value of Delay

One unexpected insight from the challenge was the peace of delayed reactions. I woke one morning to a text sent overnight. Had I read it at 2 a.m., I would have likely spent hours awake, thinking, problem-solving, and replaying scenarios in my mind. By waiting until morning, I preserved my sleep energy and mental clarity.

This experience reinforces a principle I often share with clients: delaying engagement with technology can protect your sleep and your mind. Even a short pause, leaving the phone out of reach or choosing not to open messages immediately—can reduce stress, improve focus, and create a calmer start to the day. Small adjustments like these compound into long-term benefits for both sleep and overall well-being.

5️⃣ Small Habit Tweaks Lead to Big Wins

Finally, I noticed broader shifts in my overall phone behavior. I’m reaching for it less often, and when I do, I pause: “Two more minutes…” This small trick slows automatic responses, helping me regain control over my actions. During the day, leaving the phone in another room allows for focus without distraction, which I hadn’t realized was influencing my night-time habits too.

I also experimented with placing my phone in different rooms each night. When I wake up, the brain has to pause: “Where is it?” This tiny delay gives the mind time to settle and discourages automatic grabs. It’s a reminder that small environmental tweaks and consistent practice are crucial when trying to break strong habits.

Reflection

These first 15 days have been challenging but eye-opening. I think about my phone daily and nightly (pun intended). Habits, especially those tied to technology, are hard to break—but not impossible. What has made this possible for me are three key things:

• Willingness to change – being committed to improving sleep.

  
  

• Awareness of brain patterns – noticing the stories, rationalizations, and automatic behaviors.

  
  

• Accountability – sharing progress, even publicly, reinforces consistency.

  
  

Every small win matters. Each night I leave the phone out, each morning I pause before grabbing it, and each moment I resist reflexive checking is a step toward independent, high-quality sleep. This challenge isn’t just about breaking a habit; it’s about retraining the brain to rest naturally and fully.

If you struggle with nighttime wake-ups, reliance on phones, or other sleep props, know that change is possible. Small adjustments, environmental tweaks, and consistent practice can retrain your brain and improve your nights.
