You perform, but recover less well
You maintain the pace at work or in sport, but sleep, energy or adaptability no longer respond in the same way.
Psychoneuroimmunology (PNI)
When everything affects everything,
one part is not enough.
PNI explores how habits, stress, sleep, digestion, metabolism and immune regulation interact.
It may start here
You do not need to know
which system to look at first.
The assessment starts with what you notice, what life demands of you and what you want to recover or prevent.
You sleep, but do not feel restored
Your schedule, mental load, light, activity and diet may be interfering with the same recovery process.
Digestion shapes your day
Digestive discomfort, food tolerance or changes in bowel habits begin to affect your energy and routines.
You want to act earlier
You want to understand trends, risk factors and modifiable habits before a problem limits your life.
A symptom is a signal.
Context completes the story.
The body responds as a network. PNI organises that information to set clinically meaningful priorities.
-
01
Stress and regulation
Psychosocial load, neuroendocrine response and adaptation strategies.
-
02
Sleep and rhythms
Timing, rest, light exposure and physiological recovery.
-
03
Digestion
Habits, symptoms, digestive function and the gut-brain axis.
-
04
Metabolism
Energy, body composition, activity and available biomarkers.
-
05
Immunity and inflammation
Modifiable factors that influence response and resolution.
-
06
Hormonal balance
Sleep, stress, nutrition and activity in their neuroendocrine context.
The process
Not a pre-set
protocol.
The plan is built after assessing the case and adjusted as it evolves.
-
01
Listen
Your reason for attending, history, goals, medication, supplements and personal context.
-
02
Connect
Habits, nutrition, sleep, stress, activity, digestion, recovery and available tests.
-
03
Prioritise
Define what matters, what can be modified and what needs medical assessment.
-
04
Intervene
Set realistic goals and progressive lifestyle strategies within the scope of PNI.
-
05
Review
Assess adherence, symptoms, objective measures and response before adapting the plan.
Health does not mean never responding to stress. It means adapting, recovering regulation and becoming available again.
At ETRYUM, this biological flexibility becomes a practical principle: do not accumulate interventions, but understand which mechanism deserves attention and how its progress can be assessed.
Areas of intervention
A plan built around
your priority.
These are not fixed packages. Areas are selected and combined according to the initial assessment, goals and progress.
Digestive health and the gut-brain axis
Dietary, behavioural, sleep and stress factors related to digestive function.
Stress and neuroendocrine regulation
Load, habits, recovery and adaptation strategies suited to your context.
Sleep and circadian rhythms
Timing, light exposure, routines and factors that interfere with restorative sleep.
Metabolism and body composition
Nutrition, activity, sleep, stress and metabolic trends that may be modified.
Immunity and inflammation
Habits and context associated with inflammatory processes and adaptability.
Recovery under high demand
Sleep, load, nutrition, stress and recovery for athletes and high-demand professionals.
Versions
The same PNI perspective.
Adapted to your context.
The plan is built around what your life demands and the stage you are in.
Athletes and high performance
Who it is for: People who train or compete and notice they recover worse, sleep worse or perform below expectations.
What it focuses on
- Sleep, load and recovery
- Food and digestion around training
- Coordination with sports medicine and physiotherapy
Women and hormonal stages
Who it is for: Women whose hormonal stages affect their energy, rest, digestion or mood.
What it focuses on
- Rhythms, sleep and stress at each stage
- Adapted food and habits
- Coordination with the physician when needed
Professionals under heavy load
Who it is for: Professionals who sleep but don’t rest, and feel daily demands are already taking their toll.
What it focuses on
- Stress load and regulation
- Realistic routines for complex schedules
- Energy and capacity to adapt
Clinical judgement
Integration also means
knowing when to refer.
PNI does not replace medical diagnosis or treatment. If warning signs, abnormal results or a concern requiring investigation appear, the case is coordinated with the appropriate professional.
Tests and biomarkers are interpreted in context. An isolated value does not become a diagnosis or a promise of results.
Your specialist
Cristóbal Becerril
Psychoneuroimmunology
Stress · Sleep · Metabolism · Digestive health
A registered nurse (Alicante College of Nursing, no. 15778) with postgraduate training in clinical psychoneuroimmunology. Cristóbal brings together the person's history, habits, environment and available clinical information to build an individual, progressive and reviewable plan. He coordinates with medicine, physiotherapy and other professionals when needed.
View full profileDo I need a diagnosis to request a PNI assessment?
No. You may attend because of a group of symptoms, difficulty recovering or a preventive goal. The first assessment organises the information and identifies the appropriate next step.
What should I bring to the first consultation?
Any recent reports, blood tests or investigations you already have, plus an up-to-date list of medication and supplements. You do not need new tests before speaking to the team.
Does PNI replace a medical consultation?
No. PNI works on habits and modifiable factors within its scope. Diagnosis, prescribing and medical treatment remain the responsibility of a physician and are coordinated when appropriate.
Does everyone receive the same protocol?
No. The areas, intensity and duration are decided after assessment and adapted to response, adherence and goals.
Can it support athletes or high-demand professionals?
Yes. It can assess sleep, habits, load, stress and recovery, coordinating with sports medicine or physiotherapy when needed.
Can I send medical information through the form?
No. The form is only for requesting contact and arranging an assessment. Clinical documents are collected later through the appropriate channels.
