NeuroHyperSensitivity™ (NHS)
NeuroHyperSensitivity™ (NHS) is a genetic, neurological, and physiological reality. It describes a nervous system that is built to register, process, and respond to stimuli at an intensified level. People with NHS live with heightened awareness, deeper emotions, and a nervous system that processes internal and external input more intensely; not as a choice, not as a mindset, but as biology.
Core principles
◉ NHS is genetic: It reflects inherited patterns in how the nervous system is wired, regulated, and maintained over time. ◉ NHS is neurological: It involves differences in brain processing: how quickly and deeply information is registered, integrated, and stored. ◉ NHS is physiological: It shows up in the body: heart rate, stress responses, sensory thresholds, fatigue, pain, digestion, sleep, and recovery.
For people with NHS, ordinary environments can feel like “too much” long before anyone else notices a problem. Crowded rooms, complex emotional dynamics, background noise, subtle shifts in tone, or health changes are picked up quickly and intensely. This is not weakness or drama; it is a nervous system that is tuned differently.
◉ Sensory: sound, light, textures, smells, crowds. ◉ Emotional: deeper emotional resonance, longer processing, strong inner responses. ◉ Cognitive: over‑analysis, pattern detection, connecting dots quickly. ◉ Physiological: faster stress activation, slower recovery if unsupported.
NHS is not “HSP.”
Highly Sensitive Person” (HSP) has been popularized as a vague psychological or personality trait. It is often treated as a self‑help label, a brand niche, or a marketing hook. That framing is scientifically and physiologically inaccurate for what I describe as NeuroHyperSensitivity™.
NHS is not a mood, an identity trend, or a “soft” personality quirk. It is a biological reality with measurable consequences for how people perceive, process, and live.
When sensitivity is treated as a simple personality trait, the physiological burden and complexity of living with a highly sensitive nervous system are trivialized. NHS restores this conversation to where it belongs: in genetics, neurobiology, and physiology.
Why NHS matters
◉ To give people a precise, dignifying language for their lived reality
◉ To anchor care, support, and self‑management in biology, not blame or stigma. ◉ To push back against the oversimplified, monetized “HSP industry” and AI‑generated noise that make people feel seen but not truly understood. ◉ To guide research, clinical practice, coaching, and self‑care with a more accurate model.
As a scientist and as a person with NeuroHyperSensitivity™, my work is to build and communicate this framework in a way that is biologically honest, psychologically nuanced, and practically useful. If your nervous system matches what I describe here, you are not “too much” and you are not a trend. You are NeuroHyperSensitive™; and you deserve tools that respect that.
If you recognize yourself in NeuroHyperSensitivity™ and want to help build research, medical collaboration, and advocacy around NHS, you can apply to join the membership after completing a brief 5‑question NHS questionnaire.
Dr. Sahin's Mission: As a geneticist and a person with NeuroHyperSensitivity™, Dr. Sahin is dedicated to: ◉ Advancing scientific research and medical recognition of NHS ◉ Educating the public, professionals, and organizations on its true nature ◉ Correcting misinformation and raising awareness ◉ Providing a community and evidence-based resources for those with NHS
For those seeking tailored guidance, Dr. Sahin’s 1:1 Power Coaching program offers one-on-one support informed by scientific expertise and lived experience. Power Coaching is designed specifically for individuals with NHS who want to maximize their strengths and navigate challenges with evidence-based strategies.
Note:
◉ NHS is a neurological and genetic condition. It is not a psychological construct, personality type, or a subset of any other diagnosis. ◉ For more information, read the Start Here guide or visit our NHS Membership page or contact Dr. Sahin directly here.
