Is Myelina Health a medical device?

No. Myelina Health is a wellness companion — not a medical device, diagnostic, or treatment. Myelina, the AI energy companion inside the app, produces predictions and coaching as informational suggestions, never clinical advice.

How does the prediction work?

Each morning you complete a quick check-in covering sleep, energy, stress, and cognition. Myelina, the in-product AI energy companion, compares your input to your own historical patterns to generate a visual Energy Map. Myelina is a software agent, not a medical device — its predictions are informational only.

Do I need a wearable?

No. Myelina Health works entirely from your daily check-ins. Wearable support is optional.

Yes. Your data is encrypted, stored securely, and never sold or shared. You own it and can download or delete it at any time.

Is Myelina Health a medical device?

No. Myelina Health is a wellness companion — not a medical device, diagnostic, or treatment. Myelina, the AI energy companion inside the app, produces predictions and coaching as informational suggestions, never clinical advice. It is designed to help you spot patterns and plan your day around your energy. It complements your neurologist's care; it does not replace it.

How does the energy prediction work?

Each morning you complete a quick tap-based check-in covering sleep, energy, stress, and cognition. Myelina — the AI energy companion inside Myelina Health — compares your input to your own historical patterns to render a calm Energy Map: where your energy is likely to peak, dip, or crash. Myelina is a software agent, not a medical device, and its predictions are informational only. The more consistently you check in, the sharper the map becomes.

Do I need a wearable?

No. Myelina Health works entirely from your daily check-ins. Wearable support (Apple Watch, Fitbit, Oura) is optional and adds passive signals like sleep and HRV — but is never required.

Who is Myelina Health for?

Myelina Health is built for women living with MS who deal with fatigue and unpredictable energy. Whether your diagnosis is relapsing-remitting, secondary progressive, or primary progressive — if fatigue makes planning your day difficult, this is designed with you in mind. We are currently invite-only to keep the experience high-quality for every member.

How do I get an invite?

Join the waitlist on this page — we review submissions and send invite codes in small batches. If you know a current member, ask them to refer you from inside the app.

Yes. Your data is encrypted, stored securely, and never sold or shared. You own your data and can export or delete it at any time. Myelina Health treats your information as personal health information and protects it accordingly.

Does the app respect my system “Reduce motion” setting?

Yes. Myelina Health automatically detects your operating system's prefers-reduced-motion preference and adapts the entire experience: hero parallax, headline letter-rise, scroll reveals, page transitions, and decorative atmospherics are simplified to instant fades — no translation, scaling, blurring, or staggered character animation. If you prefer a different setting just for this app, go to Settings → Accessibility → Motion and choose Full, System, or Reduced. Your choice is remembered on this device and overrides the OS preference for Myelina Health only.

Is MS fatigue the same as being tired?

No. MS fatigue is a primary symptom of MS, separate from ordinary tiredness, and it does not reliably respond to sleep, caffeine, or willpower. It is closer in quality to the flu than to a long day.

Why is MS fatigue often described as heaviness?

Damaged myelin forces your nervous system to work harder for every signal, including the signal to move. The result is a sensation that your limbs are weighted, even when muscle strength tests are normal.

Does MS fatigue feel different in the morning vs the afternoon?

Yes. Many people with MS describe a workable morning followed by a sharp afternoon collapse, often between 2 PM and 5 PM. Tracking your energy across the day usually reveals a clear window of higher function and a predictable cliff.

Can MS fatigue be both physical and cognitive at the same time?

Yes, and it usually is. Physical heaviness and cognitive fog often arrive together because both stem from the same underlying disruption in nerve signaling.

How do I describe MS fatigue to someone who does not have it?

Compare it to the flu rather than to tiredness. Most people understand the flu's full-body shutdown — that is closer to what MS fatigue actually feels like.

What Does MS Fatigue Feel Like? Real Descriptions

The honest answer

MS fatigue is not the tiredness you feel after a long day. It is closer to the way your body feels when you have the flu — a heavy, full-body shutdown that arrives without warning and does not respond to a good night's sleep.

The clinical term is lassitude. The lived term is harder to find. Here is the language people with MS use most often.

The heaviness

The first thing most people describe is weight. Limbs feel filled with sand or wet cement. Lifting an arm to brush your teeth takes deliberate thought. Standing up from a chair becomes a small project. The heaviness is not in your muscles in the way ordinary muscle fatigue is — it is in the signal your brain is sending, and the signal is "no."

The fog

Cognitive fatigue is the second layer. Words you know stop arriving on time. You read the same paragraph three times. Simple decisions — what to eat, which task to do next — feel impossibly large. People describe it as thinking through mud, or watching the world from inside a glass jar.

The disproportion

What confuses people who do not have MS is the disproportion. You did the dishes and now you cannot speak. You went grocery shopping and you are in bed for two days. The cost is wildly out of proportion to the activity, and that is the part that wrecks plans and relationships.

The unpredictability

Unlike ordinary fatigue, MS fatigue is non-linear. You can sleep nine hours and still wake up depleted. You can have an easy week and crash anyway. Heat, hormones, infection, stress, and barometric pressure all push on it. So does carrying the cognitive load of a normal workday with a body that is not normal.

The 5 PM cliff

Many women with MS describe a predictable afternoon collapse, often between 2 PM and 5 PM, where energy that was workable in the morning falls off a cliff. Some call it "the wall." It is real, it is common, and it is one of the patterns a daily check-in surfaces quickly.

How to tell it apart from regular tiredness

Ordinary tiredness	MS fatigue

Improves with sleep	Often unchanged by sleep
Proportional to effort	Out of proportion to effort
Predictable	Can arrive without trigger
Mostly physical	Physical + cognitive at once
Lifted by caffeine	Caffeine rarely touches it

What helps you describe it to others

Borrow this sentence: "MS fatigue is closer to having the flu than to being tired. It is a full-body shutdown I cannot push through, and pushing through it costs me the next two days." People who do not have MS understand the flu. That is the bridge.

Tracking it

The most useful thing you can do is separate the layers. Each morning, score your physical heaviness and your cognitive fog separately. After 2–3 weeks of [daily check-ins with Myelina Health](/ms-fatigue-tracker), the pattern that emerges tells you which layer is driving your hardest days — and which intervention will actually move it.
