Sleep, sustainability and society: key insights from the 2024 Cambridge Integrative Review

A recent integrative review published in Cambridge Prisms: Global Health (2024) highlights sleep as a foundational element of public health and sustainable development. The analysis demonstrates that sleep is not merely a biological necessity—it is deeply shaped by social, economic, and environmental conditions, and is closely connected to many of the UN Sustainable Development Goals (SDGs).

1. Sleep as a pillar of human sustainability

Sleep influences essential functions such as cognition, memory, emotional regulation, metabolic health, mental wellbeing, and workplace safety. Poor sleep quality is associated with:

• higher prevalence of chronic diseases,

• reduced productivity,

• increased risk of accidents,

• deterioration of mental health and stress regulation.

For these reasons, sleep is positioned as a critical determinant of sustainable human development.

2. A socio-ecological model of sleep

The review adopts a socio-ecological perspective, showing how sleep is shaped by multiple levels of influence:

• Individual factors: age, gender, lifestyle, genetics.

• Social factors: income, job insecurity, shift work, family stress, discrimination.

• Environmental factors: noise, air pollution, overcrowded housing, artificial light, urban density.

• Structural and policy factors: labour regulations, urban design, public health policies, socioeconomic inequality.

Sleep emerges as a sensitive indicator of the broader conditions in which people live.

3. How sleep connects to the Sustainable Development Goals

The article links sleep to a wide range of SDGs, grouped into three major areas:

A. Social and economic inclusion

The review shows that sleep quality is significantly affected by:

• poverty and food insecurity (SDG 1–2),

• inadequate or unsafe housing (SDG 11),

• environmental pressures such as noise and pollution (SDG 13).

Vulnerable groups—including low-income households, shift workers, minorities, and women—face a disproportionately higher risk of sleep disturbances.

B. Wellbeing and quality of life

Insufficient sleep limits progress in several human-development-related SDGs:

• SDG 3 – Good health and wellbeing: sleep is fundamental to physical and mental health.

• SDG 4 – Quality education: sleep supports learning, attention, and memory.

• SDG 5 – Gender equality: women often face heavier care burdens and more fragmented sleep.

The review stresses that adequate sleep is crucial across all stages of life, especially during childhood and adolescence.

C. Economic and environmental sustainability

Sleep is directly linked to working conditions and economic productivity (SDG 8).
Shift work, night work, long commuting times and high job strain are identified as major disruptors of healthy sleep.

Additionally, sustainable and well-designed urban environments—characterised by green areas, reduced noise, clean air and safe neighbourhoods—play a key role in enabling restorative rest (SDG 9, 11, 13).

4. Global sleep disparities

A central finding of the review is that sleep reflects and amplifies social inequalities.
Populations with limited socioeconomic resources are more likely to experience:

• irregular working schedules,

• precarious employment,

• poor housing conditions,

• higher exposure to pollution,

• chronic stress linked to financial instability.

These experiences create a cycle in which inadequate sleep leads to poorer health and reduced productivity, further reinforcing vulnerability.

5. Conclusions and recommendations

The review concludes that:

• Sleep should be recognised as an essential determinant of global health and sustainable development.

• Policies aimed at achieving the SDGs must incorporate sleep-supportive environments—at home, at work, in schools, and in cities.

• Improving sleep equity requires coordinated action across public health, housing, education, labour policy, and environmental protection.

Sleep is therefore not merely a personal habit, but a collective condition that contributes to healthier, fairer, and more sustainable societies.
