Structured sleep hygiene training programs improve sleep quality and duration in physically and operationally demanding occupations

A systematic review of 10 studies (8 RCTs, 2 NRCTs) found that structured training programs for sleep hygiene led to moderate improvements in sleep quality and small-to-moderate effects on sleep duration in workers in physically and operationally demanding occupations. Phone assistance programs had minimal effects, and single lecture interventions had negligible impact. Evidence certainty was low due to imprecision, risk of bias, and indirectness.

Mechanism Graph

Structured training programs provide comprehensive sleep hygiene education
↓
Interactive sessions enhance engagement and behavior change
↓
Repeated exposure reinforces sleep-promoting habits
↓
Improved sleep hygiene leads to better sleep quality and duration

Limitations

  • ⚠Low evidence certainty due to imprecision, risk of bias, and indirectness
  • ⚠Heterogeneity in intervention delivery and outcome measures across studies
  • ⚠Limited number of studies (n=10) and small sample sizes

Frequently Asked Questions

What are the most effective sleep hygiene interventions for military and emergency personnel?▼

Structured training programs (multi-session, interactive) show moderate improvements in sleep quality and small-to-moderate effects on sleep duration. Phone assistance and single lectures are less effective.

How strong is the evidence for sleep hygiene interventions in high-demand occupations?▼

Evidence certainty is low, ranging from very low to moderate, due to risk of bias, imprecision, and indirectness. More high-quality RCTs are needed.

Do sleep hygiene interventions improve sleep duration in shift workers?▼

Structured training programs have small-to-moderate effects on sleep duration, but the overall evidence is limited and of low certainty.

What is the difference between structured training and single lecture interventions?▼

Structured training involves multiple interactive sessions, while single lectures are one-time passive education. Structured training shows greater benefits, whereas single lectures have negligible impact.
