Ornamental indoor plants in hospital rooms enhanced health
outcomes of patients recovering from surgery
Seong-Hyun Park and Richard H. Mattson (2010)
Department of Horticulture and Recreation Resources, Kanas State University,
Manhattan
Objective:
To study the health benefits of patients on viewing indoor plants on stress and
recovery of surgery .

Kentia palm
(Pteris cretica )
Dendrobium
(Dedrobium phalaenopsis)
Variegated vinca
(Vinca minor )
Golden pothos
(Epipremnum aureum)
Arrowhead vine
(Syngonium podophyllum)
Peace lily
(Spathiphyllum)

Ninety (90) patients recovering
from hemorrhoidectomy were
randomly assigned to either
control or rooms with plants.
Patients in control were allowed
to view only the sky with no
presence of trees or other
buildings.
Patients in plant room were
allowed to view plants during the
recovery periods.
Plant arrangement were made
identical in each room.
Patients were not involved
with plant maintenance.

Data collected for each patient
• Length of hospitalization
• Analgesics used for postoperative pain control
• Pain intensity
• Anxiety
• Fatigue
• Patient’s room satisfaction questionnaire

Pain tolerance effect of ornamental plants
S.H. Park, R. H. Mattson and E. Kim (2012)
Department of Horticulture, Forestry and Recreation Resources
Kanas State University, Manhattan, USA-66506
Objective:
To examine pain tolerance effects of ornamental plants in
a stimulated room

Materials & Methods
Experimental setting
• Room size - 6.0 m X 3.9 m X 2.7 m
• Experimental section – 3.9 m X 2.3 m X 2.7 m
• Computerized bio monitoring system ( F1000, Focused technology, USA )
• Room - White colour wall, no windows.
• Light – White fluorescent
• Intensity of light – 904 lux
• Room temperature – 21.70 C (±0.3)

Treatments
• T1 - Foliage & flowering plants
• T2 – Foliage plants only
• T3 – No plants

Dendranthema grandiflora Dianthus caryophyllusBegonia semperflorens

Ficus benjamina Chlorophytum cosmosumEpipremum aureum

Subjects
• Ninety female students were recruited and assigned to the treatments
thirty students per treatment
• The mean age of the students was 18.9 years(±1.1)
• They were distributed among the three treatments with respect to age,
year in school, academic major, residency and geographic origin

Pain Induction
• Cold pressor test is followed to assess the pain tolerance.
• Students were asked to immerse their dominant hand in hot water at
37oC for 2 min, so that the temperature of all students dominant
hands are similar.
• Then each of them were asked to immerse their hand into an ice
bucket as long as they could tolerate the pain (max up to 5 min)

Observation
• Self rating of pain intensity and pain
distress based on a ten point scale were
taken at the end of the session

A general reaction of a body to any demand made on it.

89 percent of India’s population suffering from stress; most
don’t feel comfortable talking to medical professionals.
About 89% of the Indian population in India say they are suffering from stress compared to the
global average 86%.
Nearly 75% of them don’t feel comfortable talking to medical professionals.
Workplace stress scored high.
BY ET BUREAU I JUL 10, 2018, 9.56 AM IST

Stress causes various type of reactions….
1. Physical - fatigues, headache, insomnia, muscle ache, heart
problems, chest pain, sweating, obesity, blood pressure.
2. Mental - decrease in concentration & memory, indecisiveness,
confusion, loss of sense of humor
3. Emotional - anxiety, nervousness, depression, anger, frustration,
worry, fear, irritability, impatience, short-temper
4.Behavioural - nail biting, foot taping, blaming, drinking, smoking,
crying, yelling.
5.Lifestyle - imbalanced food habit, lack of sleep, daily routine.

The Effect of Indoor Foliage Plants on Heath and
Discomfort Symptoms among Office Workers
Tove Feld, Bo Veiersted, Finn Levyd (2011)
Department of Horticulture and Crop Sciences, Agricultural University of
Norway
Objective:
To assess the effect of foliage plants in the office on health and
symptoms of discomfort among office personnel

Materials & Methods
Office room – 10 m2
Relative humidity - 30 to 40%
Air Temperature – 22 to 24oC
Plants used
• Aglonema commutatum (4)
• Dracena deremensis (2)
• Epipremunum aureum (4)
• Philodendron scandens (3)
• Dracena fragrans (1)

• A total of 59 office employees at a Norwegian oil company participated in the study.
• The subjects completed a questionnaire every 2nd week about 12 different health
symptoms during two spring periods.

Neuropsychological symptoms
The mean sum score of fatigue, feeling heavy-headed, headache, nausea/dizziness and
concentration problems.
This sum score was reduced by 23% if the offices contained
plants (p = 0.008), from a mean score of 2.6 to a
mean score of 2.0

Fatigue
• Complaints regarding fatigue were reduced by 30%, from 0.82 to 0.58

Mucous Membrane Symptoms
• Introducing plants reduced the mean sum score
by 24% from 2.5 during the control period, to 1.9
when plants were present.
• During the period with plants complaints
regarding dry, hoarse throats were reduced by
25% and for cough by 37%

Skin Symptoms
• The presence of plants did not affect this group of
symptoms.
• However, complaints about dry or flushed facial
skin were significantly reduced 23%when the
subjects had plants in their offices.

Sum of Symptoms
• The mean score summarized for all 12 symptoms had a value of 7.1 during the period
without plants.
• A 21% reduction was found during the period with plants.

Conclusion
The present study strongly suggests that foliage plants in the office improve health and
reduce discomfort symptoms.
Major explanations are:
1) Improvement of air quality by the plants
2) Increase in general well-being due to the perception of foliage plants

PLANTS IN THE CLASSROOM CAN IMPROVE STUDENT PERFORMANCE
John Daly , Margaret Burchett & Fraser Torpy (2010)

Materials & Methods
• Three schools in the Brisbane region with a total of over 360 students in 13 classes
 All saints, Albany Creek, Brisbane North ,(3 classes each of grade 6 & 7, with an
average of 25 pupils = 150 )
 All Saints, Merrimac, Gold Coast (Middle school – 4 classes: 120 pupils)
 St Joseph’s Tobruk Memorial School, Beenleigh, Loganlea (3 composite classes,
Grades 6 & 7; 90 pupils )
Plants used – Epipremnum aureum
Dracena fragans
Sapthiphyllum sp.

• A period of about two months was needed to formulate and process the
test structure.
• Standard testing method was devised.
• Participating classes then received a total of 3 plants per classroom, while
the remaining classes received no plants.
• Students were tested before plant placements and re-tested after about six
weeks of plant presence (or absence).

Test Measures
 Spelling (South Australian Spelling Test, SAST)
 Mathematics
 Science

Discussion…..
• Indoor plants significantly improves indoor air quality.
• Plants can significantly reduce levels of CO2 and air-borne volatile organic compounds
(VOCs) that are continually outgassing from plastic/synthetic surfaces.
• The CO2 level has been reduced due to plants which reduces the risk of drowsiness to
students.

Effects of Interior Plantscapes on Indoor Environments and
Stress Level of High School Students

National Horticultural Research Institute Rural Development Administration Suwon 441-707,Korea
Objective:
To examine how in-class plantscapes affect indoor environment and the stress
level of students

Materials & Methods
• Subjects
• Two high schools in Seoul (J & K)

• 23 students (K)
• 19 students (J) Participated in all experiments
• 45 students (K)
• 53 students (J) Participated only in health assessment portion

Plants were positioned in the classroom to
create a favourable green view rate of
30%.
The plantscape accounted for about 5% of
the overall volume of classroom.

Plants used
• Nephrolepis exaltata
• Pachira aquatica
• Scindapsus aureus

Observations
Mental stress Health conditions Indoor environment
Symptoms were
assessed three times
•One week prior to
installation of the plants
•Six weeks after installation
