Environment in pediatric wards: light, sound, and temperature

Area of Science:

• Pediatric healthcare
• Environmental health
• Sleep medicine

Background:

• The relationship between sleep and disease is critical, especially during hospitalization.
• Hospital environments can significantly influence patient sleep and recovery.
• Understanding environmental factors in pediatric wards is essential.

Purpose of the Study:

• To describe environmental factors (light, sound, temperature) in pediatric wards.
• To assess if these factors align with recommended standards.
• To characterize sleep quality in hospitalized children.

Main Methods:

• Measured light, sound, and temperature in five pediatric wards.
• Compared measurements against recommended standards (light ≤100 Lux, sound ≤45 dB, temperature 20-24°C).
• Assessed children's sleep quality via caregiver questionnaires.

Main Results:

• Light levels were acceptable 86% of the time.
• Sound levels exceeded recommendations (above 45 dB) 85% of the time.
• Temperatures were above 24°C for 78% of the time.
• Caregivers reported worse sleep quality and more restlessness in the hospital.
• Noise was a primary cause for awakenings.

Conclusions:

• Hospital sound and temperature levels frequently exceeded recommendations.
• Variations between wards suggest a lack of standardized environmental controls.
• Hospitalization was associated with poorer sleep quality and shorter sleep duration.
• Further research is needed on environmental impacts on pediatric recovery.
