01
Sleep that looks adequate but is fragmented
Seven to nine hours per night is the adult range, but multiple awakenings, late caffeine, and irregular bedtime can leave you tired despite the hours.

Persistent fatigue
Find what is actually draining you.
Low energy is rarely one thing. It is usually a combination of sleep quality, common nutrient deficiencies, and lifestyle patterns — most of which are measurable.

I sleep eight hours and I am still exhausted by 2pm every day. My doctor said my TSH was normal.
Ingrid
A normal TSH only answers part of the question. In situations like yours, iron stores, vitamin D, and sleep that looks adequate in hours but is fragmented are all worth discussing with your GP.
First action
Ask your GP about ferritin and vitamin D
Upload a recent blood panel or ask your GP for these values so your next conversation can cover both nutrient status and sleep quality.
Illustrative example only. Ingrid helps organize likely contributors and next questions; diagnosis remains a clinical decision.
Possible causes
Common drivers of persistent fatigue
These are the factors most often behind persistent low energy in otherwise healthy adults.
02
Iron status, even when within range
Low ferritin can contribute to fatigue even before iron-deficiency anaemia is obvious, especially in menstruating adults and people with low iron intake.
03
Vitamin D deficiency
25(OH)D below 30 ng/mL (75 nmol/L) is widely considered insufficient and is associated with low mood and fatigue. More common in northern climates and during winter months.
04
Thyroid dysfunction
Hypothyroidism is a well-established cause of fatigue. TSH alone is the typical first screen, but in some cases additional values (free T4, free T3, antibodies) help complete the picture.
05
Sleep apnoea
Loud snoring with witnessed breathing pauses, morning headaches, or daytime sleepiness despite adequate hours warrants a clinical assessment. Untreated sleep apnoea is a common, treatable cause of unexplained fatigue.
06
Chronic stress load
Sustained psychological load can worsen sleep, concentration, and energy long before people describe themselves as “stressed.”

“Sleep is important, but not important enough to lose sleep over.”
Sleep affects almost every aspect of our mental and physical health. But some people get so anxious about it that bedtime becomes a battleground. When we fixate less on sleep, and find professional help if needed, often it improves.

How it works
A structured look at what is draining you
Three practical steps from scattered clues to a targeted next move.
- Step 01
Share what you have
Bring together the signals that usually explain fatigue best: sleep structure, habits, symptoms, and any recent blood work.
- Use wearable sleep data or a short manual log
- Upload common labs like ferritin, vitamin D, and TSH if available
- Capture caffeine, timing, and symptom patterns in context
- Step 02
Ingrid reads the picture together
Ingrid weighs sleep quality, nutrient status, stress load, and medications together so the likely driver is clearer.
- Rank the one or two contributors most worth checking first
- Avoid generic supplement lists and low-value guesses
- Explain why those factors matter in plain language
- Step 03
A targeted plan, plus a GP summary
You get one focused action plan and, when appropriate, a concise summary to bring into a GP appointment.
- Start with one high-yield change rather than twenty tips
- Use the summary to ask for the right follow-up tests
- Escalate faster when fatigue needs clinical work-up

When to see a doctor
When to see a doctor
Fatigue with unintended weight loss, fever, night sweats, or shortness of breath should not be self-managed. Persistent unexplained fatigue lasting more than a few weeks warrants a clinical assessment.
FAQ
Common questions
Does Ingrid look at my health as a whole, or one signal at a time?
Most apps look at one signal: steps, sleep, or weight. Most clinicians see only what you bring to the appointment. Ingrid combines wearable data, labs, family history, medications, and self-reported habits in one place — and uses all of it when suggesting what to do next.
Will Ingrid adapt as my data and habits change?
The plan is not written once. Ingrid reviews your progress weekly, identifies what is and is not working, and adjusts the plan accordingly. The recommendations a month from now will look different from the ones today — because they should.
When does a clinician get involved?
Ingrid is not a replacement for a clinician, and does not pretend to be. For anything that needs a diagnosis or a prescription, Ingrid summarises the context and routes you to a verified human expert.
Do I need a recent blood test?
Helpful but not required. Ingrid works with the data you have. If labs would change the picture, Ingrid will say so.
How quickly will I feel different?
That depends on the contributor. When sleep or a nutrient deficiency is involved, addressing it can make a noticeable difference within a few weeks — your own data will show whether it is working.
Can I share findings with my GP?
Yes — Ingrid generates a one-page summary in clinical language your GP can act on.
What about chronic fatigue syndrome (ME/CFS)?
Ingrid is not a substitute for clinical assessment of suspected ME/CFS. For symptoms lasting more than three months without explanation, Ingrid will recommend a specialist pathway.
A coach that reads everything you share. A clinician who steps in when the question is clinical.
Ready when you are
Your data already has most of the context. Let Ingrid read it.
Start with the symptom or goal you care about. Ingrid helps connect it to the rest of your health picture, then adapts with you over time.
- Reads sleep, labs, habits, and symptoms together
- Prioritizes the one or two highest-yield contributors
- Turns scattered clues into a GP-ready summary
