What actually helps with Long Covid — and how NESA fits into care.
There is no miracle cure. There is energy management, care for the autonomic nervous system, and consistency. We explain the established approaches — and NESA's honest place among them.
Three approaches that are not in dispute in the clinical guidelines.
Pacing — energy management, not graded exercise
Limiting exertion below the individual threshold for post-exertional malaise (PEM): planning, prioritising, resting before exhaustion rather than after it. This is the central recommendation from the CDC, WHO and NICE for Long Covid — unlike protocols for ordinary deconditioning, gradually “pushing” the limits here can cause harm.
Targeted care for orthostatic intolerance / POTS
With a confirmed diagnosis: increased fluid and salt intake (on medical advice), compression garments, reclined/semi-reclined positioned movement before upright activity, and, if needed, medication prescribed by a cardiologist. Always after diagnosis, never on your own.
Symptomatic treatment and multidisciplinary follow-up
Sleep, nutrition, psychological support for anxiety/depression arising from the chronic condition, and treatment of specific identified disorders (e.g. deficiencies, sleep disorders) — coordinated by the treating physician.

The device supports your system — it does not replace it.
NESA XSIGNAL® works with controlled microcurrents through the limbs, aimed at the balance between the sympathetic and parasympathetic nervous system — a mechanism documented in 18+ indexed studies of NESA in other indications and used in more than 50 public hospitals and ~1,500 private clinics (see the evidence section).
If a patient's autonomic nervous system achieves better balance, that work belongs to the nervous system itself — the device creates conditions that support the process; it does not “cure” on the body's behalf. Published NESA results on heart rate variability, sleep and mental clarity — measured in other patient groups — can be found in the “Documented results” section of the science page.
- There is no published clinical study of NESA specifically in Long Covid.
- NESA complements pacing and medical care — it does not replace them and does not override medical follow-up.
- With pronounced PEM, any new intervention, including non-pharmacological ones, requires explicit attention and medical consultation.
- Absolute contraindications (pacemaker, pregnancy, active electrical implants) follow the device's IFU.
What a supporting programme looks like.
Diagnosis and assessment by the treating physician — including a check for POTS/orthostatic intolerance.
Drawing up an individual pacing plan — an energy budget, not gradual loading.
Discussing with a therapist whether NESA sessions are a suitable addition — with realistic expectations.
Follow-up and adjustment of the plan together with the treating physician — not self-experimentation.
Discuss your specific case with us.
We explain the NESA mechanism, the available protocols, and how to assess whether it is a suitable tool within the patient's overall plan.
