NESA. Attention to sleep, rest and recovery.

What does your nervous system have to do with this?

The autonomic nervous system automatically regulates functions such as heart rate and digestion. It helps your body respond to exertion and settle into rest. Research into NESA explores whether weak electrical stimulation can influence this regulation.

Neuromodulation means influencing nerve activity. It is not a literal reset of your body. Poor sleep, pain and fatigue can have various causes; these symptoms do not automatically mean your autonomic nervous system is dysregulated.

What does the device do?

The NESA system delivers weak electrical current through multiple electrodes, including at the hands and feet. It is being studied for influencing functions of the autonomic nervous system. This system regulates processes that occur without conscious control. What treatment means for a specific complaint needs separate investigation.

What happens during a session?

First, we explain how the electrodes are placed and the chosen programme. The skin at the contact points must be suitable for the application. You remain at rest during treatment.

• Your supervisor places the electrodes and checks contact.
• The device runs through the agreed programme.
• Report discomfort or other symptoms immediately.
• Afterwards, we discuss your experience and next steps.

What do we discuss beforehand?

Alongside your question, we discuss your health, relevant medication and any implants. Suitability is checked against the device instructions and your personal situation. The description ‘weak current’ does not replace that assessment.

What does research on sleep show?

A small placebo-controlled study involving 12 professional basketball players measured, among other outcomes, less wakefulness at night. A placebo-controlled pilot from 2026 found improved sleep questionnaire scores in women with an overactive bladder. That analysis included 43 participants who completed the programme.

These are positive signals within specific groups. They do not prove an effect in everyone who is tired or sleeps poorly. Small groups and study design limit certainty. Persistent insomnia still requires appropriate assessment and conventional sleep treatment.

What about burnout, fibromyalgia or long COVID?

You can come to us with questions about these symptoms. During the intake, we discuss the diagnosis, what has already been investigated and the support you receive. The research described here does not show that NESA cures these conditions.

With long COVID or ME/CFS, minor exertion can increase symptoms later. Report such worsening beforehand: treatment at rest is not automatically suitable or without exertion. We tailor any proposal to your situation and do not replace ongoing medical or psychological support.

Is NESA also used for an overactive bladder?

This is another application being studied. A small pilot in women with an overactive bladder found fewer daily toilet visits and improved sleep questionnaire scores. Not all outcomes improved. This calls for larger follow-up studies, not a general treatment promise.

Do you often experience sudden urgency or other urinary symptoms? Have your GP assess the cause first. We then discuss separately whether complementary treatment is appropriate.

Your experience makes it personal

If NESA becomes part of your plan, we agree what you want to monitor, such as your experience of nights or rest breaks. Together, we discuss changes, including when there is no improvement or treatment feels unpleasant. NESA does not guarantee improvement in sleep or fatigue.
