Incense and Allergies: What to Know If You Have Asthma or Sensitivities

Incense and Allergies: What to Know If You Have Asthma or Sensitivities

Incense has long been used to bring scent, calm, and ritual into our lives. Whether it’s lighting a stick for meditation or burning a cone to cleanse a space, the aroma and atmosphere it creates can be deeply grounding. But for those with allergies, asthma, or respiratory sensitivities, incense can sometimes raise questions—Is it safe for me to use?

If you’ve ever felt your throat tickle, nose itch, or chest tighten after burning incense, you’re not alone. In this post, we’ll explore how incense affects those with sensitivities and how to enjoy incense more safely—without giving up the rituals you love.

Why Can Incense Trigger Allergies or Asthma?

When incense burns, it produces both fragrance and smoke particles. For most people, this is a pleasant experience. But for people with respiratory conditions, especially asthma or environmental allergies, the fine particles in the smoke can irritate the airways, triggering symptoms such as:

  • Coughing or throat irritation
  • Sneezing or nasal congestion
  • Headaches
  • Shortness of breath or chest tightness (especially for asthmatics)
  • Watery or itchy eyes

According to a study published in journals like Chest and Environmental Health Perspectives, incense smoke contains volatile organic compounds (VOCs) and fine particulate matter (PM2.5)—tiny particles that can stay suspended in the air and be inhaled deep into the lungs.

While the levels of exposure from casual incense use are much lower than from, say, cigarette smoke, people who are sensitive may still experience discomfort, especially in poorly ventilated spaces or when using synthetic incense with added chemicals or fragrances.

What the Research Says

Several studies have explored the connection between incense and respiratory health:

  • A 2001 study from Environmental Health Perspectives found that long-term exposure to heavy incense smoke in enclosed spaces may contribute to respiratory inflammation and increase the risk of asthma-like symptoms.
  • A 2014 study published in Journal of Asthma reported that indoor incense use was associated with a higher prevalence of wheezing and other asthma symptoms, especially in children.
  • A 2011 study highlights that incense sticks emit particulate matter (PM2.5) and trace gases that can impact indoor air quality and trigger asthma symptoms.

However, it’s worth noting that occasional, well-ventilated use of natural incense likely poses low risk for most people without chronic lung conditions. The type and quality of incense used can make a big difference.

Choosing Incense That’s Gentler on Your Lungs

If you have asthma, allergies, or other sensitivities, but still want to enjoy incense, the good news is: not all incense is the same. You can still create a safe, aromatic experience by being mindful about what you burn and how.

Here are a few tips:

1. Choose natural, low-smoke incense

Look for incense made from pure plant-based ingredients—woods, herbs, resins, and essential oils—with no artificial fragrance, fillers, or chemical binders.

Try: Sandalwood, frankincense, or palo santo in small amounts

2. Avoid incense with synthetic additives

Many commercial incense sticks use synthetic perfumes, dyes, and charcoal bases that produce thicker smoke and irritants. If you don’t recognise the ingredient list or if the smell is overly strong or perfumed, skip it.

3. Burn in a well-ventilated space

Always keep a window cracked open or use a fan to help circulate air. Avoid burning incense in small, enclosed rooms. Proper ventilation ensures smoke doesn’t linger in the air and reduces the risk of irritation.

4. Start small and watch your body

Try burning only a portion of a stick or cone at first and observe how your body reacts. If you feel fine after 5–10 minutes, you may be able to continue. If not, stop immediately and clear the space.

5. Use incense as an occasional ritual

If you’re sensitive, treat incense as a special occasion tool—not something to burn all day. Enjoy it once or twice a week during meditation, journaling, or wind-down time rather than as a constant scent source.

Alternatives to Burning Incense

If you love scent but are concerned about smoke, you can still enjoy smoke-free alternatives that are gentler on the respiratory system:

  • Herbal sachets or potpourri placed around your space
  • Non-toxic candles made with natural wax and essential oils
  • Room sprays with plant-based ingredients and no synthetic perfume

These options give you the power of aromatherapy without the smoke.

Final Thoughts

Having asthma or allergies doesn’t mean you have to give up your incense ritual entirely. With care, awareness, and the right products, it’s possible to enjoy the scent and sacredness of incense without discomfort.
