Introduction: CBT-I as a Solid Foundation, but Not the Whole System

Over the past three decades, Cognitive Behavioral Therapy for Insomnia (CBT-I) has emerged as a central consensus approach in guidelines for the non-pharmacological management of chronic insomnia.

By systematically addressing sleep-related maladaptive thoughts and behaviors, CBT-I has helped countless individuals break the vicious cycle: Backed by robust clinical evidence, CBT-I is widely recognized as the “gold standard” for the non-pharmacological treatment of chronic insomnia.

Yet, today’s sleep-related challenges are far more pervasive:

• A large number of people experience chronic sleep restriction without meeting formal diagnostic criteria;

• Some have near-normal objective sleep metrics but still report unrefreshing sleep and daytime fatigue;

• Many grapple with the combined burdens of stress, irregular schedules, suboptimal diet, stimulant use, and screen exposure;

• Sleep tracking technologies are growing in popularity, yet users often lack guidance on translating data into meaningful improvements.

Furthermore, modern sleep problems often arise from the interplay of sleep, emotion, chronic disease, and environment, with a significant portion of demand originating in non-medical settings such as homes, workplaces, schools, hospitality, and long-term care facilities.

In this context, relying on a single clinical technique is inadequate. What is needed is a more comprehensive integrative framework that connects:

• Individual needs with the broader sleep ecosystem;

• Medical and non-medical settings;

• Theoretical models with real-world application.

To address this gap, Worldsleep – World Sleep Network proposes:

WST-I:

Draws on CBT-I as a key evidence-based component; Is grounded in the 3H Holistic Health Model; Seeks to systematically integrate traditional wisdom, lifestyle medicine, and emerging technologies into an open, ecosystem-focused framework.

The 3H Holistic Health Model: A Higher-Level Map for Sleep

Prior to developing WST-I, the Worldsleep team developed an overarching conceptual framework from a holistic health perspective: This model provides a macroscopic framework for understanding the role of sleep within overall health.

2.1 Health

Sleep is not merely “hours spent asleep.” It is closely linked to: Emotional regulation; Metabolic and cardiovascular function; Immune competence; Cognitive performance and long-term brain health.

Meaningful improvements in sleep should be reflected not only in nighttime metrics, but also in: Daytime alertness and functioning; Emotional well-being; Physical vitality; Reduced long-term health risk profiles.

2.2 Harmony

The essence of healthy sleep lies in alignment and balance: Between intrinsic biological rhythms and social schedules; Between stress load and recovery processes; Between individuals and their light, sound, temperature, air quality, and bedding environments.

In many cases, the core issue is not simply “insomnia” but a chronic misalignment between internal rhythms and external demands. Restoring such harmony is a prerequisite for sustainable sleep health.

2.3 Humanity

Sleep problems often reflect tensions in a person’s relationship with: Themselves; Others; The broader world.

Metrics and technologies alone are insufficient. People also need to experience empathy, understanding, and support, and to regain a sense of safety and agency in the process of improving sleep.

Within the 3H model, sleep is both: A sensitive indicator of holistic health, and A practical entry point for health-promoting interventions. WST-I is conceived as a way to operationalize “sleep” along this holistic map.

WST-I: An Integrative Framework Linking Individual Sleep Health and the Sleep Ecosystem

WST-I is designed as a multi-source, open, and collaborative integrative framework, encompassing four interrelated layers:

3.1 Theoretical Layer – Multi-Source Integration

WST-I seeks to integrate multiple knowledge streams, with its core foundation being CBT-I and established sleep medicine theories. It also incorporates scientific support from neurobiology, lifestyle medicine, and wisdom supplements from traditional practices like Ayurveda, aromatherapy, and mindfulness.

These are not treated as equivalent “therapies,” but as sources of potentially useful modules that can be integrated and evaluated within a unified framework.

3.2 Technology Layer – Bridging Clinical and Everyday Contexts

The technology layer focuses on bridging clinical and everyday applications. This includes compatibility with clinical tools like PSG, and using consumer tools like wearables for self-management, not diagnosis. A key aspect is the clear definition of red-flag criteria and referral pathways from non-medical support to medical evaluation, ensuring safety.

3.3 Product Layer – From Single Products to Components of Solutions

In WST-I, products are positioned not as isolated solutions, but as components within structured intervention programs. The framework helps quantify the role and added value of each product, supporting a shift from “selling devices” to “designing coherent intervention pathways”.

3.4 Service & Talent Layer – WSA / WSP / WSE Competency System

To make WST-I learnable, applicable, and scalable, a tiered competency structure is proposed: WSA (Associate), WSP (Practitioner), and WSE (Expert). This structure is explicitly non-medical in scope and is intended to complement, not replace, clinical roles.

Worldsleep: Enabling WST-I to Circulate Across the Sleep Ecosystem

Even the best framework requires an ecosystem to operate within. One of the core aims of Worldsleep – World Sleep Network is to serve as a coordination and connectivity platform for the WST-I framework.

From a systems perspective, effective sleep health implementation depends on five core modules working together: Industry, Education, Research, Medical, and Service. Any missing or weak link in this chain constrains overall impact.

Worldsleep’s role is to: Connect these five modules into a more coherent system; Provide a shared framework (WST-I) as a common reference for collaboration; and Facilitate the circulation of methods, tools, and talents across settings and regions.

When these modules are aligned, and WST-I serves as a shared integration framework, the sleep field can evolve toward a more connected, efficient, and sustainable ecosystem.

Conclusion: WST-I as an Open Starting Point

In this position paper, WST-I is presented as: An integrative technology framework, Grounded in CBT-I and the 3H Holistic Health Model, Designed to link individual sleep health with the broader sleep ecosystem.

It is not proposed as a replacement for existing clinical guidelines or therapies, but as an open, evolvable structure for: Organizing existing knowledge and practices, Designing multi-dimensional interventions, and Facilitating cross-sector collaboration.

Future work will involve: Empirical testing of WST-I-aligned programs; Refinement of its components based on data; and Ongoing dialogue with stakeholders worldwide. WST-I is thus intended as a starting point for global collaboration on integrative sleep health, rather than a finished answer.
