I don’t trust the results. They don’t match how I feel

For some measurements, you may feel that the results “don’t make sense” or don’t match how you feel. This is very common and in most cases, completely natural.

1. The measurement captures the activity of the autonomic nervous system (ANS)

Elonga evaluates ANS activity using spectral HRV analysis an objective physiological method supported by thousands of studies. The ANS works automatically and without conscious control. This means:

• it doesn’t always react the way subjective feelings suggest,

• it can be dysregulated even when you feel fine,

• it may appear calm even if you feel tired.

2. Feeling ≠ actual physiological state

Your subjective perception is shaped by mood, psychology, expectations, motivation, and daily context. The ANS responds to physiological processes you cannot consciously sense.

Therefore, it is common that:

• you feel rested, but ANS shows stress,

• you feel tired, but ANS is fully recovered,

• results shift earlier than subjective symptoms appear (e.g., approaching illness).

3. The ANS reacts to hidden factors

These may include:

• emerging infection (often visible in HRV earlier than symptoms),

• psychological stress or anticipation,

• lack of sleep,

• hormonal changes,

• lingering physical fatigue.

You may not be aware of these factors, but the ANS senses them and the results reflect that.

4. Can I trust the results? Yes.

If the measurement is performed correctly and under standardized conditions, it accurately reflects your physiological state. HRV spectral analysis is a validated and widely used scientific method for assessing ANS activity.

5. Why are the results sometimes “surprising”?

Unexpected values are often not errors, they simply reveal something you wouldn’t notice otherwise. Examples:

• your system is reacting to an internal or external stressor,

• ongoing recovery from prior load,

• objective fatigue even without the feeling of being tired,

• early illness development.

Elonga is very sensitive and often detects changes before you consciously feel them.

6. How should I work with the results?

• Always measure correctly- morning, lying down, calm, before food/coffee/activity, and without focusing on the outcome.

• Don’t compare feelings to results 1:1- they represent different layers of your state.

• Focus on long-term trends, not isolated days.

• If a result looks unusual, watch the next 1–2 measurements- the meaning usually becomes clear.
