Humidifiers in hospital settings

  • Comment

Introducing humidifiers into a hospital during winter improves staff satisfaction, say Japanese researchers.

They surveyed 45 staff members about symptoms of dry skin or thirst before and after the humidifiers were introduced for one month.

The humidifiers increased relative humidity in sickrooms from 32.8% to 43.9% on average. Complaints of thermal discomfort and dryness of air decreased among staff, the authors said.

‘Introducing humidifiers into a hospital setting during winter is an effective method of improving the low-humidity environment and relieving the discomfort of staff members,’ they said.
