Great climate: indoor plants increase well-being

Houseplants are not just sources of oxygen and humidifiers. Some species can even absorb environmental toxins such as formaldehyde, benzene, or trichlorethylene.

People exhale carbon dioxide and moisture, both of which are deposited in the room air. In addition to the temperature, these factors determine the ability to concentrate and well-being. A room temperature between 18 and 21 degrees with a humidity of around 50 percent is ideal. According to the Federal Environment Agency, the carbon dioxide concentration in the room air should also not be too high.

Green plants can bind pollutants

Pollutants from furniture, carpets and building materials dissolved in the room air can cause dizziness, irritation of the mucous membranes, headaches, allergies, asthma or diseases of the paranasal sinuses in sensitive people. Green houseplants can help improve the indoor climate in a natural way - and even bind pollutants.

Oxygen dispensers and humidifiers

Tip: The more plants that are set up, here nest ferns, the greater the oxygen and humidification capacity.

Green plants convert carbon dioxide (CO2) into oxygen, among other things, via the chlorophyll in their leaves with the help of sunlight. This biochemical process is called photosynthesis. Another advantage of indoor plants is the natural humidification of the air, because more than 90 percent of the irrigation water is diverted back to the environment - and free of germs. With dry heating air in winter, this is a boon for the nasal mucous membranes and thus an effective prevention against colds. At high temperatures in summer, the moisture supply also ensures pleasant coolness.

The following applies: the more plants, the greater the oxygen and humidification performance. Large-leaved species such as room linden, nest fern, cyprus grass, ficus, cob thread or aralia species are well suited for this purpose. Depending on the watering intervals, indoor plants can increase the humidity by around five percent.

Special plants for the bedroom

Bromeliads are a plant that absorbs carbon dioxide overnight.

A good indoor climate plays an important role, especially in the bedroom. While plants usually emit carbon dioxide at night when photosynthesis has come to a standstill, there are species that take it up during this time. They can be perfectly placed in the bedroom. These plants include bow hemp, real aloe, bromeliad and orchid, among others. The use of clay granules is recommended to reduce maintenance costs through frequent watering. They are also less prone to harmful mold infestation than normal potting soil.

Tropian plants for darker corners

The most common indoor plants come from the tropics. It is very dark under the dense canopy of leaves of the rainforest and the plants that grow there are also suitable for dark corners in your own four walls. If you love palm trees, you can set up the Kentia palm there, for example. This originally grows in the undergrowth and needs little light - penumbra or shadow are completely sufficient for it. However, it is a bit sensitive when watering and should always have a slightly moist soil.

If you don't want to water a lot, you can get a Zamioculcas, also called a lucky feather. It actually has only one problem - most of the time it is watered too much, which causes the plant to die. Native plants, such as the begonia, also feel at home in partial shade and shade. Ivy or ferns are also suitable for cooler room temperatures between 10 and 18 degrees.

Green plants as natural pollutant killers

If the room air is polluted with formaldehyde, green lilies can be an effective remedy.

However, some of the green room occupants can do a lot more: Certain types are able to filter toxins such as formaldehyde (chipboard from furniture), benzene (paints and plastics) or trichlorethylene (paints / varnishes, chemical cleaning agents) from the room air. Australian scientists have established in a series of tests: Green plants can reduce the pollution in indoor air by more than 50 percent.

For this purpose, plants such as ivy, philodendron and dragon tree, but also the single leaf or nest fern can be used universally. If you want to specifically reduce the formaldehyde load, you should set up the real aloe or the green lily at home.

Even NASA has already experimented with these plants to improve the air in spaceships and recommends placing a plant in an area of ​​ten square meters. The great advantage of the plant filters in contrast to conventional room air filters is that they have low operating costs, do not require electricity, in the best case do not have to be constantly replaced, that they are noiseless and convert 80 percent of the irrigation water into humidity. By the way: You don't even need a green thumb for most of these plants. They are also conveniently easy to care for.
