Carbon Dioxide and Sleep (11-22-17)

Carbon dioxide levels in sleeping areas affect how well we sleep.  Mishra and colleagues conducted a related study: “Bedroom carbon dioxide level, temperature, and relative humidity were measured over 5 days, for two cases: open window or door (internal, bedroom door), and closed window and door. . . .  Average carbon dioxide level for the Open conditions was 717 ppm . . .and for Closed conditions was 1150 ppm. . . . Absolute humidity levels were similar for both conditions, while Open conditions were slightly cooler (mean = 19.7 degrees Celsius . .

Moving Nature (10-24-17)

Zijlstra and colleagues probed the effects of seeing images of moving nature on patient anxiety levels.  The team “investigated whether the use of motion nature projection in computed tomography (CT) imaging rooms is effective in mitigating psycho-physiological anxiety (vs. no intervention). . . . motion nature projection had a negative indirect effect on perceived anxiety through a higher level of perceived pleasantness of the room [when motion was present, anxiety was lower and the room was perceived to be more pleasant]. . . .

Environmental Control for Younger Patients (10-20-17)

Trzpuc and her team investigated factors that contribute to the wellbeing of patients in child-adolescent mental health units.  During a study completed at the University of Minnesota Masonic Children’s Hospital Child–Adolescent Mental Health Inpatient Unit they found via patient surveys that  design features in which patients have choice and control offer greater perceptions of calm during their stay in the unit [i.e., patients perceived they were calmer when these opportunities for choice and control were present].”  Data were collected in two areas, one of which had bee
