The Allergy Dossier

Air pollution in India is a cause of major concern as the pollutant levels have risen steadily in most of the Indian cities. While most of us are aware of the pollution that we encounter day in and day out on our roads, we know precious little about the innumerable pollutants that are present indoors, affecting the quality of life of millions of people. I have been afflicted by chronic allergy for the past several years and if you are a regular reader on my blog, you would have come across my lighthearted take on it at the The Perennial Sniffles.

In 2012, I took a break from my IT career, post which I no longer spent long duration in air-conditioned offices and instead started spending a substantial amount of time indoors at home. That period also curiously coincided with the time my allergies started aggravating. According to an article published in NCBI, indoor air pollution is 10 times worse than outdoor pollution. In India, the major cause of indoor air pollution are combustion, building materials, fine particulate matter and bio-aerosols. Indoor air contains pollutants from both indoor as well as the outdoor.These air-born agents cause asthma, bronchitis, allergies and irritation of the respiratory tract. It took a long time for me to associate my increased time at home, with my increase in allergies.

In a bid to reduce the pollutants and the effects they had on me, I started researching on several alternatives. In this post, I summarize some of the key points and also hope that it helps other allergic people, find some solution to their problems.

Environmentally sustainable designs : A well ventilated and optimally designed house helps to prevent mold and mildew formation. Keeping a good air flow allows the free exchange of indoor and outdoor air and reduces build up of toxins. Many composite building materials emit VOCs (Volatile Organic Compounds). Substituting these materials for naturally occurring materials and buying formaldehyde free furniture reduces our exposure to such allergens. If you haven’t already invested in a permanent home, this could be a good thing to keep in mind. However many of us may not have the option to change our house construction and adapt to sustainable designs.

Air purifiers / Air filters : Air purifiers and air filters with HEPA filters are another great way to maintain air purity. They work by filtering particles from circulating air using filters, electrical attraction or ozone. While choosing air purifiers , choose ozone free ones as ozone can aggravate asthma and respiratory issues. However, they are expensive with the normal price range in India in the region of 17K to about 40K. Smart Air Purifiers look more affordable at the price range of less than 5K, however most of the air filters will have a running cost of replacing the HEPA filters at regular intervals, in the absence of which the fan can burn out due to clogged filters.

Air Conditioning : Air conditioners have some basic stuff to remove dust and odour filtering, but ACs are in no way a replacement for Air Purifiers. AC’s refrigerant gas leakage can also be a source of air pollution. However, ACs may marginally improve air quality depending on what’s your allergy trigger. I have often experienced my allergy coming down, if I sit in the car with the AC on for some time.

Indoor plants : Keeping indoor plants is a great way to increase the oxygen levels inside the house. Several plants which are ideal include the ubiquitous money plant, bamboo palm, areca palm, Aloe Vera. Plants like the Snake Plant (Sanseviera Trifaciata) releases oxygen at night and hence is ideal for bedrooms. If you keep the windows closed at night due to high allergies, improving oxygenation levels inside the room might be good idea. Check out this awesome video where Kamal Meattle talks about growing fresh air !

Removing allergens like dust and dust mites : Professional cleaning of dust and dust mites, with high powered vacuums and spring cleaning your sofa and bedding could go a long way. The picture below is not of a scrumptious chocolate cake but of the dust cleaned from sofa. The froth on the surface are the eggs of the mites. Yuck !

Reducing dust and particulate matter : Home furnishings should be critically looked at, from the point of view of capturing dust. Reduced usage of carpets, heavy furnishings and fabric heavy sofas can drastically lessen the amount of dust and dust mites.

Pet dander : While I adore dogs and cats, my allergic nature leads me to strongly suspect the possibility of pet dander aggravating it. Pet dander is a known issue which causes allergies and knowing beforehand whether you are vulnerable to it, might be the most important thing for yourself and for your future pet.

Reduce Strong Smells : Having the kitchen well ventilated is extremely important. Indian cooking emits a lot of strong smells and it’s lately been causing a lot of my allergy attacks. Reducing exposure to strong scents / deos / chemicals can reduce the chances of an allergy attack. Opt for natural ingredients in personal care products and try unscented variations of deos / antiperspirants.

Humidity Control: Humidity plays a key role in regulating mold, mildew and dust mites. Both high and low humidity act as asthma triggers. High humidity could result from water leakage / seepage, plumbing leaks or moisture retained in building materials. Drying clothes inside the house can also result in high humidity. Plugging the sources of high humidity and ensuring good ventilation should lower humidity.But very low humidity can also result in dry airway passages, dry skin etc. This can be alleviated to a certain extent, by letting clothes air dry and letting more air evaporate inside the house. One can also invest in a good humidifier.

Allergy proof bedding: Investing in allergy proof linen can also help in reducing inhalation of allergens while sleeping. These sheets /covers which are dust-mite resistant can be spread on top of the bed. However, I did come across some research which mentioned that the reduction in allergies due to allergy proof bedding was not conclusive.

Air friendly Paints: Interestingly, Asian Paints has come out with a novel product called Royal Atmos. The paint is supposed to help eliminate odors by absorbing smells like smoke, ammonia, garlic etc. For a person who’s prone to allergy, strong smells can trigger an allergy attack. This also absorbs formaldehyde.Formaldehyde is an important chemical used widely in the manufacture of building materials and a number of household products and therefore, can be present in substantial concentrations in the house. Exposure to formaldehyde can cause irritation of eyes, nose, skin and throat. The paint also contains low levels of VOC which is within permissible limits. Since we plan to get our house painted soon, this paint will definitely be on my consideration list.

Air Pollution Masks : Air pollution masks are a good bet to reduce the impact of poor air quality. However not all masks are the same. The commonly available surgical masks are practically useless for an allergic person. Look for N-99 (which filters out 99% of PM2.5


particulate matter) and N-95 masks (which filters out 95%). N99 is ideal for those who suffer from constant allergies. The best deal for the N99 mask is the Atlanta Healthcare Cambridge mask, priced at Rs.1999, which I started using recently.The recently introduced Vogmasks are also a good value for money.Check out this link for some great information.

Pranayama and Yoga: Pranayama has healed a lot of people of allergies. Undoubtedly improving your breathing and lung power could go a long way in ensuring good respiratory health. Kapalbhati pranayam is slated to be very effective for allergies.

Last but not the least, Eat Healthy with plently of fresh fruits and vegetables.

Methods to alleviate an allergic episode:

However, as all the allergic know, its not always possible to control allergens, especially the ones which are air-borne, at every place and all the time. So despite taking all precautions, allergic episodes can occur very commonly and can diminish the quality of life. These are some of the methods which I have either tried or read about.

Neti : Neti ie, the yogic practice of usage of salted water to clean the nasal passages, is a very helpful method. However I have also read that continuous practice of Neti could also remove the helpful bacteria and mucous.


I normally resort to Neti, when I get a sinus infection superimposed on my allergies. But all care must be taken to do it the right way and its very important to dry your passages well, after doing Neti. Adequate care must also be taken to use filtered, boiled and cooled water, usage of Neti-salt or sea salt and finally maintaining the water at the right temperature. I found steel neti pot to be the best, as its possible to clean and sterilize it. Ideally one should consult a yoga practitioner who can guide on the correct way of doing Neti.

Steam Inhalation: This is one of my go-to techniques in the event of an impending allergy or cold. The steam goes into your nasal passages and gives instant relief for any heavy sinus or mucous. There is a good variety of electric steam inhalers to choose from. I have found the method of using the steam inhaler with a towel draped all around the head and the inhaler works the best, as the super hot steam doesn’t directly hit your face and at the same time, concentration of the hot steam all around your face, brings immediate relief.  In case you are stuck without an electric one, you could make one by boiling water directly on the gas. Fold a thick paper / cardboard in a conical manner such that the narrow opening of the cone faces the steam and the broader one is over your face.

Sipping warm liquids : Drinking warm liquids helps to thin the mucous and enables breathing easier. You can have green tea or apple cider vinegar with honey and lemon in warm water. In situations where none of these are available, sipping continuously on warm water also helps relieve congestion.

OTC Medicines: Mostly anti-histamines work by reducing the histamine level in your blood, which is the reason for allergic reactions. But most of these meds also produce a side effect of drowsiness. Levoceterizine is commonly used and doesn’t have a long term side effect. Though a reduced dosage of Montek-LC has worked for me quite well,  I would suggest getting your allergies tested and getting a doctor prescription.

Ayurveda / Homeopathy : Homeopathy has a lot of remedies for Allergies, however its efficacy seems to be highly person dependent. In my case, it hardly had any effect while I know of people for whom it was very effective. Ayurveda also has some remedies for allergy, though I have not tried them.

Immunotherapy : Also known as allergy shots, this is a therapy by which your allergen is tested and a small amount of allergen is introduced in the blood. This causes your body to generate immunity and reduce sensitivity to the allergen. This procedure is expensive, long drawn and need not always be successful. I have not yet resorted to this and hopefully will not have to, if all the other preventive methods can be used.

Would love to hear your suggestions on how you improve air quality and reduce pollutants / allergens.If you are a fellow allergic, do write in how you combated your allergies.

  1. That is a comprehensive dossier. I was hooked by the video that suggests indoor plants for balancing the air within, although the quantity suggested per person is daunting and it might boost the mosquito population in your home. Yoga is certainly a great remedy to allergies. The Royal Atmos paint sounds magical –I am certainly going to try that out. Thanks for those tips!

    Pertinent post given that most of us suffer from one allergy or the other. A senior doctor I spoke to said there is little point getting allergy tests as our bodies get over old allergies and develop new ones. You have listed some great tips. An air purifier is on my mind.

  3. That’s a comprehensive list. I’ve used the same drugs, Levoceterizine and Montek LC for my son. Montek gave a definite cure for night coughs especially. But if he stops taking the medicine, the allergic cough revives. Sometimes it feels strange where, what, how it’s getting triggered.

    1. Yeah, such a hard thing to discover the cause. Even allergy tests are not definitive. Trial and error by changing my exposure to different stuff, helped me identify air related allergens to some extent. Thanks for commenting !

  4. Informative post.
    Air Pollution is a an unfortunate reality.
    There’s a lot we need to do.
    I had watched Kamal Meattle’s video earlier. Plants & trees and eco-friendly measures can help.

  5. You have provided an impressive list of allergy causing issues. Many of these irritants are prevalent because of our own behaviours. For instance, “pet dander” can be reduced to a large extent if pet owners groomed their pets and brushed them regularly. However, instead of looking for easy solutions most people who have been told by their doctors that they are allergic to pet dander drive away the poor animal from their homes rendering them homeless.
