NESA · Psychology & psychiatry

Stress regulation the body absorbs.

NESA balances the autonomic nervous system — regulating stress, anxiety and sleep, as a complement to psychological and psychiatric care.

Self-recognition

Do you recognise yourself?

Anxiety and inner tension

a mind that won't stop
racing heart
muscle tension
fatigue
difficulty falling asleep
a sense of anxiety for no reason
What happens in the autonomic nervous system

Like a fire alarm that wails — with no fire. In anxiety the “gas” takes command and the “brake” (vagus) does not engage in time.

Self-assessment, not self-diagnosis — discuss with a professional.

Why NESA in mental health

Focus, order and calm — through autonomic balance.

01
01

Stress & anxiety

Reduction of sympathetic overactivity and of subjective tension.

02
02

Sleep

Better sleep quality — a key factor for mental health and recovery.

03
03

Sensory regulation

Support in autism spectrum disorders and sensory difficulties.

04
04

No pharmacological load

A non-invasive method that combines with psychotherapy and pharmacotherapy.

How it works

Microcurrents that recalibrate the nervous system.

NESA applies controlled low-intensity (0.1–1 mA) low-frequency (1–15 Hz) microcurrents through eight electrodes on the four limbs and one guide electrode. The signal reaches the autonomic nervous system and supports the balance between its sympathetic and parasympathetic branches.

In mental health this means lower sympathetic overactivity, deeper and more stable sleep, and better stress regulation — objectively measurable via EEG (increased alpha activity in the prefrontal cortex) and heart-rate variability.

Frequently asked questions

Short answers for professionals.

Is the therapy safe?

Yes. NESA is a non-invasive, low-intensity method with no known systemic side effects. Sessions are conducted by a trained specialist.

Does it replace psychotherapy or medication?

No. NESA complements psychotherapy and pharmacotherapy by improving stress and sleep regulation — it does not replace them.

When are the first results felt?

Many patients report better sleep and calm after 4–6 sessions; a durable effect builds over the full course.

Are there contraindications?

Pacemakers and other active implants, pregnancy and epilepsy require prior medical assessment. When in doubt, consult the treating physician.

Therapeutic logic

At the core: programmes P1–P9

Every protocol in this field combines the reference programmes P1–P9 — general homeostasis, body levels, ANS/CNS and targeted nerves — according to the clinical goal.

Limits & safety

Protocols are guidelines, not prescriptions.

·

Parameters are guides; the therapist adapts them to the patient.

·

NESA is not suitable for every patient and promises no cure.

·

Absolute contraindications (pacemaker, pregnancy, active implants) follow the device IFU.
