    Allergies and Indoor Air


    Here is an interesting article from HealthNewsDigest.com which have been published on StarFit4Life, sunday 3rd February 2013.  For our information, this makes me want to take part time cleaner to do house cleaning every week.

    Even for those of us without allergies, poor indoor air quality is an often overlooked health issue.  Recent research has shown that the air inside some buildings can be more polluted than the outdoor air in the most industrialised of cities.  And since many of us spend some 90% of our time indoors, cleaning the air where we live and work might be one of the most important things we can do for our health.

    The US Environmental Protection Agency (EPA) lists three basic strategies for improving indoor air : source control, improved ventilation and air cleaners.

    Source control, whereby emissions from individual sources of pollution are eliminated or reduced – for instance, finding somewhere outside the home to store old paint and construction supplies – is typically the most effective strategy.

    If the sources of pollution are beyond your control, bringing in more air from outsiede through better ventilation is the best bet.  “Most home heating and cooling systems, including forced air heating systems, do not mechanically bring fresh air into the house,” the EPA warns.  “Opening window and doors, operating window or attic fans when the weather permits, or running a window air conditioner with the vent control open, increases the outdoor ventilation rate.”

    The agency adds that local bathroom or kitchen fans that exhaust outdoors also remove contaminants while increasing the outdoor air ventilation rate.  Air cleaners (either mechanical filters or electronic cleaners) can also help reduce or remove some forms of indoor air pollution.  “Some air cleaners are highly effective at particle removal, while others, including most table-top models, are much less so,” reports the EPA.

    “People with sensitivity to particular resources may find that air cleaners are helpful only in conjunction with concerted efforts to remove the source.” Some of us swear by our housplants for keeping our indoor air free of pollutants.  Mother Nature Network reports that certain plants are known to filter out specific contaminants : aloe removes airborne formaldhyde and benzene; spider plants scrub carbon monoxide and xylene; and gerbera daisies take the trichloroethylene left over from dry-cleaned items out of your air.

    The EPA, however, does not consider houseplants to be especially effective at air filtration, and even warns that over watered indoor house plants can, in and of themselves, present a health hazard, because damp soil may promote the growth of allergens.

    Good housekeeping also can go a long way toward improving indoor air.  WebMD reports that regular mopping and vacuuming (with a HEPA-filter-equipped vacuum cleaner), keeping interior moisture levels low, maintaining a smoke-free environment, and ditching chemical air fresheners are all key to maintaining good breathing space inside.
