Real questions from real women, answered the way I'd answer them at your kitchen table. No fluff, no hype, just the why behind the what.
I've spent 32 years at the bedside, most of it on night shift, watching what actually helps people rest and what only sedates them. These are the questions I get most, answered honestly, including the ones where the answer isn't what you'd expect.
Where this comes from
Who is Seanna Aker?
I'm a registered nurse with 32 years of clinical experience, including two decades of night shift across Labor and Delivery, the Operating Room, and Hospice. I'm also a Certified Holistic Health Coach. I didn't come to sleep science as an outside observer. I lived the wired-but-tired cycle myself for years, treating my own exhaustion as a personal failing before I understood what was actually happening in my body.
Are you a doctor, or is this medical advice?
I'm a registered nurse, not a physician, and nothing here replaces the relationship you have with your own doctor. What I offer is education about circadian biology and sleep physiology, the mechanisms behind why your sleep may have changed, so you can have better, more informed conversations with your own care team.
See the full disclaimer at the bottom of this page. It applies to everything on this site.
Are you anti-medicine or anti-supplement?
No. I'm pro-foundation, not anti-supplement. My approach always starts with what your body can already do for free, sunlight, rhythm, timing, before reaching for something to take. That's not a philosophy against medicine. It's an order of operations. Circadian biology first, functional support second, conventional intervention when it's genuinely needed. Not the other way around, which is how most of us were taught to approach it.
About the approach itself
What makes The Sleep Nurse different from typical sleep advice?
Most sleep advice hands you a list of tips with no explanation of why they work: get eight hours, avoid screens, try melatonin. Nobody tells you the mechanism. I explain the biological why behind everything, so you stop collecting tips and start understanding your own body well enough to become your own expert.
The other difference is what I lead with. Circadian biology first, functional medicine second, conventional medicine last. Most wellness content flips that order or skips the biology altogether.
Is sedation the same thing as sleep?
No, and this is probably the single most important distinction I make. When a medication knocks you out, your brain isn't necessarily moving through the sleep stages it's designed to cycle through. It's not doing the deep repair work, the memory consolidation, the immune maintenance that actual restorative sleep does.
You can be unconscious for eight hours and still wake up feeling like you were hit by a truck. I lived that for years and assumed it was my fault. It wasn't. I just didn't understand what my body actually needed, so I kept giving it the wrong thing and calling it effort.
Why does light matter so much for sleep?
Light isn't just something you see. It's information your body reads and responds to at a cellular level, whether you're paying attention or not. It governs your hormones, your temperature, your mood, and your sleep-wake rhythm. Get the light signals wrong, morning sunlight, evening screens, sleeping with lights on, and your internal clock gets confused. I call that clock chaos.
This is the foundation everything else in my work builds on, because it's free, it's available to almost everyone, and it works with your biology instead of against it.
Is this actually based on research, or is it your opinion?
Both, and I want to be honest about how they fit together. I lead with circadian biology and functional medicine, and I use peer-reviewed research to support and fill in the gaps, not as the primary lens. Where a claim is well-established science versus where it reflects a functional-medicine framing, I try to be transparent about that difference rather than blur the two together.
As a nurse, I want proof, not vibes. But proof in service of reassurance, not fear
Whether this will actually work for you
What if I've already tried everything, melatonin, sleep hygiene, all of it?
Then you've probably tried managing symptoms without addressing the underlying rhythm they're coming from. That's not a critique of your effort. Most sleep advice targets the surface (screens, caffeine, a bedtime routine) without touching the deeper circadian signaling that actually governs whether your body knows it's time to rest.
I'm not asking you to try harder at the same list. I'm asking you to understand a different layer of the problem.
What if I work night shift or irregular hours?
I understand this one from the inside. I spent two decades on night shift. The principles still apply, light exposure timing, rhythm, rest ritual, but the specifics have to be adapted to your actual schedule rather than a standard nine-to-five day. This is exactly the kind of nuance that generic sleep advice tends to ignore completely.
Do I need special equipment, light boxes, gadgets, trackers?
No. The foundation of my approach is free: sunlight, timing, and rhythm. I do talk about tools sometimes, a lux meter as a teaching aid, for instance, but that's to illustrate a concept, not because you need to buy something to start. I'll always show you the free and natural option before the expensive and manufactured one.
How long until I see results?
I won't give you a countdown, because that's not how bodies actually work, and I'd rather be honest than sell you a formula. Consistency matters more than a perfect routine. Some women notice a shift in how they feel within days of adjusting morning light exposure. Full circadian repair, especially after years of clock chaos, takes longer and happens in a steady rhythm, not a sprint.
About this site
Are you selling me something?
Sometimes, yes, I have a guide, a membership, and I do affiliate partnerships with products I actually use or would buy myself. But nothing here is built to pressure you. If something feels like a natural next step once you understand the why, I'll offer it. If it doesn't feel like a genuine yes for you, that's a real answer too.
Do you use AI to help create your content?
Yes. I use AI as a co-writing tool in parts of my process, and I keep that disclosed openly rather than hidden, because honesty matters more to me than the polish of pretending I do every single thing alone. The ideas, the clinical experience, and the voice are mine. AI helps me organize and produce them more efficiently.
Still have a question?
If you didn't find your answer here, I'd genuinely like to hear it. In the meantime, if any of this resonated, come along for the rest of it.
