The healthy indoor climate in hospitals.
In hospitals, the treatment and recovery of patients is the main focus. A health-promoting indoor climate is therefore an important component in the overall range of services offered by a medical facility.
This is because scientific findings show that the indoor climate has a major influence on the health, well-being and performance of patients, doctors and nurses. The comfort zone of a person lies between 40 and 60 % in relation to the relative humidity (RH). Between these two values, the person feels comfortable, is efficient and remains healthy.
Optimal working conditions for the mucous membranes in nose and mouth. These protect patients, visitors and medical staff against the penetration of particles, bacteria and viruses into their airways.
The transmission rate of viruses via the air is reduced because virus particles form larger droplets at a humidity level of 40-60 % and thus sink to the ground faster.
The survival time of viruses on surfaces is reduced at an air humidity of 40-60 %. Viruses with a fat cover (e.g. corona viruses) are most unstable under these conditions.
The skin's state of hydration is in the optimal range at an air humidity of 40-60 %. Complaints such as itching and skin irritation are reduced for patients and medical staff.
At an air humidity of 40-60 %, significantly less moisture evaporates via the eyes. The eyes of patients and medical staff are thus better protected against dehydration.
A humidity of 40-60 % leads to less stress symptoms, increases the quality of sleep and improves the conditions for physical activities of patients and medical staff.
Doctors, nurses and carers who feel good and enjoy good health are demonstrably more concentrated, alert and motivated. Performance improves with the increase of exactly these three factors and also depends on controlled and hygienic indoor air. This added value then in turn benefits the patients' recovery process.
The advantages for your hospital:
With heating in autumn/winter, the relative humidity decreases.
Keeping the air humidity stable in our comfort zone at 40-60 % is not always easy and can only be reliably guaranteed by technical humidification of the indoor air. Especially in autumn and winter, we quickly leave the optimal range between 40 and 60 % relative humidity due to the regular and necessary exchange of the heated indoor air with colder outside air. This is because cold air can physically absorb less moisture than warmer air. If this outside air now enters a warm room and warms up from, for example, 0 °C to 22 °C, the relative humidity (RH) of this heated air cannot exceed approx. 20 % in the end. This means that in winter, the supply of fresh air inevitably leads to a reduction in the humidity of the indoor air and to leaving the comfort zone of 40-60 %.
For this reason, the German Building Climate Association (FGK) recommends that planners, architects and operators of buildings supplement ventilation systems with professional air humidification systems to control the humidity and ensure a healthy indoor climate.
