To improve the quality of the air you breathe, indoor plants are a simple and affordable way to do just that. Not only are they aesthetically pleasing for interior spaces, they also rid the air of its toxins and freshen up the atmosphere. Moreover, indoor plants also boost oxygen levels in the air – a study researched and proven by scientists at NASA.

However, plants can also have negative effects on asthma as well. Due to this reason, it is important to understand the type of plants that would best suit your condition and purchase the right ones accordingly.

Read on to find some plants that are good for asthma, and others that are not:

Plants and the Air You Breathe

Wherever a plant is situated, they have direct interactions with the surrounding environment. They alter some factors in the environment that may or may not be beneficial for asthmatic patients.

Plants grow and survive due to photosynthesis, i.e., a biochemical process that allows plants to take in carbohydrates and release oxygen, naturally improving air quality. They also engage in phytoremediation, a process by which plants clean soil, air, and water contaminated with harmful substances.

Some of the pollutants that detoxify aggravate symptoms of asthma. Furthermore, plants also alter the composition of bacteria in the air. This helps to clear certain microorganisms that are known to be harmful to asthma.

Causes of Allergies Due to House Plants

While plants rejuvenate surrounding air, some household plants also cause the symptoms of asthma to aggravate. The two biggest factors of such aggravations are mold and pollen.

Mold

Many houseplants allergies occur from mold. If the soil is too moist, molds tend to grow. They have the ability to grow in the soil, inside the pot or around it – showcasing their problematic abilities, especially during humid months of the year.

You can check soil moisture simply by sticking your finger one inch into the surface of the plant pot. The top soil should feel dry, but the soil underneath should remain moist. Often times, people notice the top soil is dry just by looking at the pot and end up overwatering the plant to create molds.

Pollen

Houseplant allergies also emerge from pollen. This is a power dry substance that carries male reproductive cells of seed plants. Some plant species self-pollinate when the pollen moves from the stamen to the pistil, i.e., the male part of the plant to the female part of the plant.

However, cross-pollination also occurs when pollen travels to the pistils of other plants through wind or tiny insects.

Pollen is also known as ‘allergen’ since it produces asthmatic symptoms through the means of allergy. Essentially, pollens are harmless but they do tend to trigger specific reactions in people susceptible to asthma.

If you fear the presence of pollen in houseplants that may trigger your asthma, purchasing an air humidifier helps the air to stay clean. Furthermore, ‘male plants’ are known to produce more pollen than ‘female plants’ that actually help to remove the power dry substance from surrounding areas. Thus, keeping female houseplants is automatically beneficial for asthma.

Some of these compounds include formaldehyde, trichloroethylene, and benzene. The plant only requires it to be placed in a dark corner, watered once a week and its air purification properties will begin as it grows.

The major downside of Peace Lilies is that they are mildly toxic to humans and pets. If by mistake, the plant is ingested, a person or animal may feel nauseous and find it difficult to swallow food.

Other Ways to Improve Air Quality

Other than storing plants to clean the air inside your home and reduce the risk of allergies and asthma, there are a number of other solutions you can adopt for better quality air. Your primary aim is to reduce toxins and dust particles that trigger asthmatic symptoms, and once that’s done right, you’ll begin to inhale fresh air.

Some recommendations for better air quality include:

HVAC Allergy Filters

Cheap air conditioning filters do not necessarily get rid of microscopic organisms present in the air. Dust mites, pollens, molds are some of the common toxins that need necessary removal, so the air remains clean.

HVAC Allergy filters trap allergens and circulate clean air. Moreover, they include activated carbon that removes strong chemicals and odor from the air. Such types of filters with a carbon facility work well for those households that have smokers or those who use harsh chemical substances for cleaning purposes.

Air Purifiers

As technology advances, the development of air purifiers has also increased. Some of the good quality ones use HEPA filters that remove allergens and toxins from the air. They target tiny particles in the air through their highly-efficient systems and work best for those people who are allergic and prone to asthma.

Air purifiers are meant to run 24 hours a day so the air around you remains clean at all times. Investing in one, especially those with HEPA filters, may be a good decision if you continue to have trouble with allergies.
