What effects does incense have on the body?

Respiratory effects of smoke

The smoke produced when incense is burned contains tiny particles. Inhaling large amounts of these particles for a long period of time can put a strain on the respiratory system. People with respiratory diseases such as asthma and allergic rhinitis should be especially careful as their symptoms may worsen.

However, if proper ventilation is provided and the amount used is adjusted, it is unlikely to cause any major problems for healthy people. The important thing is to avoid using it for long periods of time in an enclosed space.

Possible allergic reaction

Some people may experience allergic reactions to the fragrance ingredients in incense, with symptoms including sneezing, runny nose, itchy eyes, and skin rashes.

In particular, natural essential oils can cause allergic reactions more often than chemically synthesized fragrances, so it cannot be said that natural ingredients are necessarily safe. When using for the first time, we recommend starting with a short period of time and observing any changes in your physical condition.

Chemical Substances

Some incense sticks contain chemical additives to stabilize the burn. These substances can cause headaches and nausea in some people when they are burned.

Additionally, coloring agents and preservatives may irritate sensitive individuals, so if you are sensitive to chemicals, it is important to choose products with as few additives as possible.

How to use incense safely and correctly

Proper ventilation methods

When using incense, be sure to ventilate the area. Opening a window slightly or running a ventilation fan will help maintain the appropriate smoke density. It is important to avoid using incense in a completely enclosed space and to ensure fresh air circulation.

Especially if you are using it in a bedroom, be sure to ventilate the room thoroughly before going to sleep and let the air in before you go to sleep.

Usage time and frequency guidelines

We recommend limiting use to 30 minutes to an hour per day. Also, using it a few times a week will reduce strain on your body, rather than using it every day.

Prolonged or frequent use can cause smoke components to accumulate, so it is important to leave appropriate intervals between uses.

Installation location precautions

When placing the incense, choose a stable, flat surface, keep it far away from flammable objects, and make sure to place it out of the reach of small children and pets.

Choosing a well-ventilated location will prevent smoke from accumulating in one place. However, be careful as a location with too much wind may cause unstable combustion.

Tips for choosing incense that is healthy for your body

How to choose natural materials

If you want to minimize the impact on your body, we recommend choosing products that contain a high proportion of natural materials. Among MUJI products, those made primarily from natural wood, such as sandalwood, are considered relatively safe.

Check the product description and ingredient list, and try to choose products with fewer chemical fragrances and additives.

Recommended products for sensitive people

If you are sensitive to chemicals or have concerns about your respiratory system, we recommend starting with a product that has a mild fragrance and produces little smoke. MUJI offers products with relatively mild fragrances, so it might be a good idea to start with one of those.

It is also important to do a patch test before use to check if there are any changes in your physical condition after using it for a short period of time.

Frequently asked questions

Q: Is it okay to use incense during pregnancy?

A: During pregnancy, your body is more sensitive, so we recommend using incense sparingly. If you do use it, ensure there is adequate ventilation and limit use to short periods of time. If you have any concerns, we recommend consulting your doctor.

Q: Is it safe to use incense in a home with pets?

A: Pets, especially birds and small animals, are sensitive to smoke. Avoid using incense in a space where pets are present. After using it in a different room, make sure to ventilate the room thoroughly before allowing pets near it.

Q: Is it okay to use incense every day?

A: Daily use is not recommended. Limiting use to 2-3 times a week for 30 minutes each time will reduce strain on the body.

summary

MUJI incense is a product that can be enjoyed safely as long as you follow the proper usage instructions. The important thing is to ensure adequate ventilation and to properly manage the duration and frequency of use.

Since each individual's constitution and health condition is different, when using it for the first time, start with a short period of time and carefully observe any changes in your physical condition. If you notice any abnormalities, we recommend that you stop using it immediately and consult a doctor if necessary.
