Mind
Cognition, emotions and sensory experience
Explore how stressful situations, eating behaviour and sleep habits vary together, generating questions for interdisciplinary research.
THE CONNECTION
An integrated framework. A nutrition research perspective.
WorldSleep brings its 3H philosophy—Health, Harmony and Humanity—together with a four-layer framework of nine modalities: mind, body, lifestyle and environment.
WNM explores nutrition within that wider context, connecting diet and the gut microbiome with activity, sleep behaviour and daily environments. Four research directions develop this perspective: nutrition, exercise, integrative health and traditional foods.
01 / FRAMEWORK & CONNECTIONS
How nutrition research connects with WSIT
The four layers below locate WNM’s research questions within the reference framework. Lifestyle is the main point of entry for nutrition research, with connections across the other layers.
Body
Breathing and physical activity
Consider activity, dietary intake and rest together when examining relationships between physical state and sleep.
Lifestyle
Daily routines and nutrition
Connect meal timing, dietary patterns and the gut microbiome with sleep in everyday life.
Environment
Light and living spaces
Include day and night lighting, work schedules and living conditions as context when discussing eating and sleep routines.
The research connection: consider what and when we eat, how we move and when we rest within the same everyday context.
02 / WNM RESEARCH FOCUS
Four research directions at WNM
Four areas of inquiry connect nutrition and sleep, bringing a nutrition medicine perspective to WSIT.
01 / RESEARCH
Nutrition
Lifestyle · Connected with mindExamine dietary patterns, meal timing and the gut microbiome alongside sleep. Consider how study populations, food records and sleep measures relate to one another to develop clear, reviewable research questions.
02 / RESEARCH
Exercise
Body · Connected with lifestyleStudy activity timing and volume, food intake and rest within a shared framework. Explore how sleep varies across lifestyles and how nutrition, physical activity and recovery relate to everyday routines.
03 / RESEARCH
Integrative Health
Mind · Body · LifestyleConnect lifestyle education, nutrition research and sleep medicine, including the transition from everyday health management to professional assessment. Clinical interventions such as CBT-I follow professional standards; nutrition information and clinical care have distinct responsibilities.
04 / RESEARCH
Traditional Foods
Lifestyle · Extending dietary researchExamine traditional food practices and ingredients with both dietary and medicinal uses. Distinguish proposed mechanisms, human research and real-world food use, considering safety and medicine interactions when relating traditional experience to modern evidence.
