Incense is a substance that is burned to release fragrance, and has been used for thousands of years for religious, spiritual, hygienic, and medicinal purposes. It is typically composed of aromatic plant materials, often combined with essential oils, charcoal or wood powder, and combustible binding material. Incense is available in various forms, including sticks, coils, cones, and powders, and can be separated into two main types: direct-burning and indirect-burning. While incense has been associated with certain health benefits, such as antidepressant and anti-inflammatory effects, recent studies have also linked it to negative health outcomes, including respiratory issues and an increased risk of cancer. Therefore, while laypeople can use incense, it is important to be aware of the potential health risks and take precautions, such as ensuring proper ventilation and using high-quality ingredients.

Incense health risks
Incense is a smoke-emitting substance composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing use cases. Incense can be separated into two main types: "direct-burning" and "indirect-burning". Direct-burning incense is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Indirect-burning incense, on the other hand, does not contain combustible material and requires a separate heat source.
While incense has been used for thousands of years for hygienic, spiritual, and cultural purposes, recent research reveals that there could be some health drawbacks. Burning incense poses health risks including headaches, respiratory dysfunction, dermatological sensitivity, and allergic reactions. The particulate matter in incense smoke contains carcinogens and irritants, which could lead to respiratory diseases such as asthma. Research also associates incense smoke with childhood asthma and, in general, the development of respiratory allergies since the smoke contains various irritants.
Furthermore, incense smoke has been linked to an increased risk of heart disease and cancer. A 2020 study found that burning incense may cause issues with brain health in community older adults over the age of 65, including delays in cognitive performance and a decrease in brain connectivity. However, it is important to note that the precise mechanisms behind these relationships between incense burning and brain changes require further investigation.
To reduce potential health risks, it is recommended to limit incense use and exposure to the smoke. Opening windows during or after use can help lower the risk of inhaling harmful smoke. For those with allergies and asthma, burning incense can pose significant risks, and healthcare practitioners may recommend replacing it with electric or aromatic vapors, simulated visuals, or improved ventilation.

Incense in religious rituals
Incense is composed of aromatic plant materials, often combined with essential oils. The forms taken by incense differ with the underlying culture, and have changed with advances in technology and increasing use cases. Incense is available in various forms, but it can generally be separated into two main types: "direct-burning" and "indirect-burning". Direct-burning incense, or combustible incense, is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a smoky fragrance. Indirect-burning incense, or non-combustible incense, is not capable of burning on its own and requires a separate heat source.
Incense has been used in religious rituals for thousands of years, with its usage being especially prominent in the great religions of the world. In pre-Columbian America, for example, incense burners were made of terracotta and sometimes gold. Censers of precious metal with chains for hanging have been used since the 4th century in Christian churches, and the rite of swinging the censer is practised in many rituals, both Christian and otherwise. Incense burners were also used in ancient Egypt, where they were prominent in religious rituals, such as the daily liturgy before the cult image of the sun god Amon-Re, and in mortuary rites, where the souls of the dead were believed to ascend to heaven in the flame.
Incense is also used in Hindu and Buddhist rituals. In India, incense has been used since 3,600 BC and is a traditional and ubiquitous practice in almost all pujas, prayers, and other forms of worship. In the Hindu tradition, incense is offered to God in his various forms, such as Krishna and Rama. Similarly, Buddhists burn incense at festivals, initiations, and daily rites.
In China, incense was burned during festivals and processions to honour ancestors and household gods, and it was also incorporated into Shinto rituals in Japan. The use of incense was either further developed in China or transmitted to other East Asian countries, including Korea, Japan, Myanmar, Vietnam, Laos, Cambodia, Thailand, Indonesia, Malaysia, Singapore, and the Philippines. In Chinese Taoist and Buddhist temples, the inner spaces are scented with thick coiled incense, hung from the ceiling or on special stands. Worshippers light and burn sticks of incense in small or large bundles, which they wave or raise above their heads while bowing to statues or plaques of a deity or ancestor.
Incense is also used in Christian rituals, with Methodist and Orthodox Christian groups incorporating it into their practices. In the Book of Worship of The United Methodist Church, incense is called for in the Evening Praise and Prayer service. The practice is rooted in the earlier traditions of Judaism during the time of the Second Jewish Temple. The smoke of burning incense is interpreted by both the Western Catholic and Eastern Christian churches as a symbol of the prayer of the faithful rising to heaven.

Incense types and ingredients
Incense is generally composed of aromatic plant materials, often combined with essential oils. The two main types of incense are direct-burning and indirect-burning. Direct-burning incense, also known as combustible incense, is lit directly by a flame and then fanned or blown out, leaving a glowing ember that smoulders and releases a fragrance. The incense mixture typically includes a combustible base, which binds the fragrant material together and allows the incense to burn with a self-sustained ember. Charcoal or wood powder provides the fuel for combustion, while an oxidizer such as sodium nitrate or potassium nitrate sustains the burning of the incense. Fragrant materials, such as resins, barks, seeds, roots, and flowers, are added to the base, along with essential oils or other perfume ingredients. Natural plant-based binders, such as gum arabic or gum tragacanth, are used to hold the mixture together.
Indirect-burning incense, also called non-combustible incense, cannot burn on its own and requires a separate heat source. It is often made of aromatic materials or a combination of materials, such as resins, and burns more slowly than direct-burning incense. The form and composition of incense vary across different cultures and traditions, with locally available ingredients influencing the style. For example, sage and cedar were traditionally used by the indigenous peoples of North America, while agarwood and sandalwood are the primary ingredients in Japanese and Chinese incense.
Incense can come in various forms, including sticks, coils, cones, and powder. Incense sticks, also known as joss sticks in China and agarbatti in Hindi, are the main form of incense in India and are made by rolling or moulding an incense paste around a bamboo stick. The paste typically includes charcoal dust, adhesive powder made from tree bark, and perfume ingredients like masala (a spice mix) or synthetic fragrances. Higher-quality variations have fragrant sandalwood cores. In contrast, dhoop or solid stick incense from Japan and Tibet does not contain a bamboo core and can be easily broken for portion control.
Coil incense, commonly used in Chinese cultures, is extruded and shaped into a coil without a core, allowing it to burn for extended periods, from hours to days. Cone incense, invented in Japan, burns relatively quickly, while powder incense is used for making indirect-burning incense or burned directly without further processing.

Incense alternatives
Incense has been used for thousands of years for spiritual purposes, hygiene, and health. However, recent studies have shown that there may be some health risks associated with incense burning. The smoke released from burning incense contains carcinogens and irritants, which could lead to respiratory diseases such as asthma and, in the long term, even lung cancer.
If you are concerned about the health risks of incense, there are several alternatives you can try. Here are some suggestions for incense alternatives:
Essential Oils
Essential oils are a great way to fill your space with fragrance without the smoke and toxins associated with incense. You can use essential oils in a diffuser, which releases the scent into the air without heating or burning. Some popular essential oils for meditation include sandalwood and frankincense. You can also make your own homemade deodorizer by mixing essential oils with baking soda; this will release the scent over a long period.
Candles
Candles that are infused with essential oils can be burned to release fragrance without the toxins found in incense. These candles are a healthier alternative to incense and can create a natural and pleasant aroma in your space.
Indirect Heating
Some incense materials, such as resins, wood chips, and granulated incense, can be indirectly heated instead of burned. This method still releases the fragrance but without the smoke and potential toxins.
Non-Toxic Incense
There are also non-toxic incense blends available that are free from toxins and synthetic fragrances. These blends use natural ingredients such as resins, woods, and herbs to create a delicate and lasting aroma without the smoke and ash associated with traditional incense.
Baking
Baking food in the oven, such as cinnamon apples, can fill your home with pleasant aromas that remind you of comforting meals with family. This method not only scents your space but also provides you with a tasty treat to enjoy!
These alternatives to incense can help you create a pleasant and healthy environment without the potential risks associated with burning incense.
