HEALING ENVIRONMENTS


Method The PICO system was used to search for information (see Table 1).


Outcomes Firstly, the search of international literature, provided evidence on the effects of light on paediatric, adult and elderly patients.


Light l Patients staying in spaces with access to natural light experience less anxiety, depression, stress, improve their mood and pain perception, which is reflected in reduced costs for pain medications.


l It impacts the patient’s biological processes such as the production of melatonin, which influences the sleep cycle, and therefore the circadian rhythm and alertness.


l Moderate effects have been detected to reduce the progression of neurodegenerative conditions and improve the quality of life among the elderly.


l The lack of lighting control, whether natural or artificial, influences how patients rate their sleep quality. On the contrary, the control of the light increases the patient’s satisfaction with their rest area, as well as that of the staff with their work area.


l The provision of natural light and good artificial lighting improves the patient’s perception of privacy and confidentiality and reduces medical errors.


l The sleep effects observed by manipulating the lighting exceed those achieved by the use of sleeping medications.


l Whether natural or artificial, light helps to encourage positive thoughts and emotions in seriously ill patients.


l Natural light is extremely important as it promotes a pleasant environment throughout the hospital.


Nature Secondly, research reported a positive effect with different uses of nature in healthcare places: l Real nature promotes lower levels of stress in waiting rooms.

Population Intervention


O Outcome


Characteristics of the population or type of patient. Intervention, exposure or test of interest to evaluate.


Comparation Control or comparison. Effect or consequence of the intervention.


Colour proposal, Berel code 3-0605D.


l The spaces with real nature, are considered more attractive.


l There are similar results between the use of real and artificial nature, for the reduction of stress.


l The use of nature has a positive effect in decreasing pain perception.


l The use of artificial nature helps prevent sources of infection.


Colour Finally, international literature reports the positive influence of colour: l The use of colour can have positive psychological effects on the patient.


l Colour has an important effect on people’s emotions, cognitions and behaviours.


l Colour management is one of the easiest ways to alter a space, as well as light and texture.


l The union of colour, with other environmental elements such as furniture, light or textures, obtains positive results in patients.


l It is suggested to avoid vague and pale colour palettes, because a good selection can generate clean, bright and homely environments.


l Colour can generate feelings of happiness or make the patient feel comforted in a stressful situation.


Colour proposal, Berel code 3-0605D.


l It has positive physical psychological effects, such as decreased anxiety and pain perception.


l The combination of colour with other environmental elements, such as furniture or textures, obtains positive results in patients.


In addition, there are two colours that have more positive effects in paediatric and adult outpatients, these are: green and blue.


Green l It helps to change the sense of institutionalisation of hospitals.


l It provides a feeling of nature. l According to reports, children have a preference for the colour green in pale shades, such as greenish blue.


l It is evaluated as a unisex colour. l Related to nature, it is evaluated as a positive or pleasant colour. l It promotes calm.


Blue l It provides a feeling of nature. l It provides an image of cleanliness and tranquility.


l It is evaluated as a positive or pleasant colour.


l Transmits openness/freedom and peace.
