With indoor plants you can improve the indoor climate in your home in the long term. The ideal temperature is 18 to 21 degrees - more in the living area, less in the bedroom - and plus/minus 50 percent humidity. Houseplants humidify the air in winter, lower the room temperature in summer, filter pollutants from the air and look good.
In winter, the humidity is lower because you are heating. This dries out the mucous membranes of the nose and promotes colds. Houseplants with large leaves evaporate a lot of humidity and release more than 90 percent of the water you water into the room air. These include
With green indoor plants you can increase the humidity by up to five percent, depending on the watering frequency. Cyprus grass humidifies even more effectively. On a sunny summer day, a large plant turns over several litres of water. The humidity that plants evaporate is germ-free, unlike the humidity from technical humidifiers.
Ventilate your house or flat regularly so that the indoor air does not become too humid. If the humidity exceeds 60 percent, mould can develop and endanger your health.
Certain pollutants, for example from building materials, furniture or carpets, can trigger allergies, asthma, headaches, mucous membrane irritations or dizziness in sensitive people. There are some indoor plants that filter and bind pollutants such as benzene (in paints and plastics), formaldehyde (in chipboard of furniture) and trichloroethylene (in paints, varnishes and chemical cleaning agents) as well as dust from the air. For example, dragon tree, ivy or philodendron.
How well you sleep depends on many factors. One of them is the indoor climate in the bedroom. Most plants convert carbon dioxide into oxygen during the day. Exception: plants with the Crassulaceae acid metabolism filter the carbon dioxide out of the air at night and produce oxygen when you sleep. These include, for example, bromeliads, true aloe, orchids and succulents.
In principle, you can put the same plants in your children's room as in your bedroom. Unless they have thorns like agaves, sharp edges like grasses or spines like cacti - or they smell intensely and disturb sleep. It makes sense for your children to take care of the plants themselves. That way they learn responsibility. Betel nut and kentia palms or gerberas, which come in many colours, are good examples. Older children especially enjoy Venus flytraps, which attract their victims with glittering tropicals and catch them in a flash with their leaves, which look like gaffes.
More and more Swiss people work in a home office for days at a time or for the whole week. Plants relax, muffle sound and increase your ability to concentrate when you have to work for hours on the computer or take part in many video conferences. Regardless of whether you work at the kitchen table or have set up your own study. Robust green plants with large leaves such as monstera and palms are particularly suitable for the home office - and of course for any other office as well.
Plants from tropical or subtropical regions feel at home in the bathroom because the indoor climate is humid and warm. These include bromeliads, dragon trees, green lilies, orchids or Cyprus grass and some palms, for example the mountain, betel nut or cobbler palm. However, they do not like large temperature fluctuations. You can place the plants on the floor in a large bathroom and on the windowsill, the edge of the bathtub or a rule in a small bathroom - or hang them from the ceiling. Except for ferns, all plants in the bathroom need enough light. Also make sure that no plants are in a draught or in the cold air when you ventilate the bathroom.
In the warm and humid bathroom climate, the soil will mould more quickly than elsewhere. Plant the plants in a hydroponic system or cover the top layer of soil in the pot with bird sand.
If you live in a household with children and/or animals, you should avoid poisonous indoor plants. These include among others
