Many asthmatics and allergy sufferers tend to prefer cooler environment during an attack. As such, they tend to gravitate to cooler colors because the environment is often perceived as being cooler (Stone and English, 1998). Van de Vlirt and Van Yperen (1996) note that people are less efficient when they feel it is too hot, suggesting a link between efficiency and ambient temperature. Because one’s breathing is no longer efficient during an asthma or allergy attack, it stands to reason that a person may desire cooler ambient temperatures to increase breathing efficiency.
Many asthmatics and those who suffer from severe allergies tend to gravitate to low stimulus environments. This tends to translate into minimalist design that can border on the austere. This preference may come from a feeling of being crowded, closed in, or overloaded. This may explain evidence of asthmatics preferring ambient temperatures that range from 68-73°, and men preferring cooler temperatures than women (Kopec, 2006). Likewise, high levels of stimulation can detract from focus (Stone, 2001). Hence a low stimulus environment may be desired so that the individual can focus on his or her breathing. In the redesign, it will be important to retain a low stimulus, minimalist design that is neither sterile in its appearance nor austere.
For people who suffer from asthma and allergies, the primary triggers within the interior environment are dust mites, pollen, animal dander, and cockroaches. The primary goal is to reduce surfaces where allergens can accumulate and escape periodic cleaning. Another goal is to reduce the impacts of soft features within a room such as mattresses and box springs, stuffed animals, carpeting, curtains, and bedding as possible. Soft features often act as a “sink” whereby allergens become embedded in the stuffing and fibers. These allergens are then released back into the air with interaction. An average mattress can contain as much as 2-million dust mites; about one quarter of a pillow’s weight consists of dead and living dust mites, and we spend about 1/3 of our lives in bed (Siedlecki, 2003). Based on these notions, the room was photographed and analyzed for areas concern and mitigation.
Research indicates that optimal humidity levels for those with respiratory illnesses should be between 40-60%. However, when humidity exceeds 50% there is a propensity for molds and other fungi to take root. The city of San Diego averages a high of 80% and low of 58% relative humidity levels, which suggests that ideal interior humidity can be easily attained. It is recommended that a humidifier be added to the room and used only when the relative humidity levels fall below 40%.
