Which flowers should not be kept in the bedroom? Reasons why oleander (Nerium oleander) is not suitable for the bedroom

As November arrives, the weather gradually turns colder and everyone starts to bundle up, and the windows at home are opened less often too. This situation is very hard on plants and flowers, because indoor air is relatively poorly ventilated. In particular, several kinds of plants and flowers must never be kept in a room for long periods; at best they affect sleep, and at worst they harm your health.

Oleander (Nerium oleander)

Oleander is a famous ornamental flower with beautiful blooms, but the whole plant is toxic, and it ranks among the more toxic flowering plants. If you place oleander in an unventilated environment, over time it can easily make people think more slowly, feel drowsy, or experience a decline in mental acuity. At the same time, the sap in its leaves is also highly toxic; if a cat or dog eats it by mistake, symptoms of poisoning such as vomiting, dizziness, diarrhea and arrhythmia may appear, and in severe cases, if a relatively large amount is ingested, it can even be life-threatening.

Dieffenbachia (Dieffenbachia seguine)

Dieffenbachia is a foliage potted plant, also known by the other name "dumb cane". It too is toxic as a whole plant, and the toxic parts include the stems, leaves and leaf stalks. If a cat or dog eats it by mistake, it will injure the throat, and may even cause swelling of the mouth and tongue leading to suffocation. Therefore, if you place it in a relatively unventilated space, these toxic components may spread and be absorbed through the skin, with the result being symptoms such as itching and swelling and pain. In addition, note that when pruning it in normal times, you must wear gloves to avoid direct contact with its sap.

Mimosa (Mimosa pudica)

Mimosa is a wild weed, and its leaves have a very unique charm: with just a light touch of the hand, they immediately close. However, do not let your guard down just because it is a fresh, delicate green plant; it

is slightly toxic as a whole plant. With long-term contact, skin cells will be invaded by a slightly toxic substance called "mimosine", and the result is that hair and eyebrows turn yellow or even fall out. Therefore, when growing it in autumn and winter, be sure to place it outdoors, and do not put it in a bedroom with doors and windows tightly closed.

Tulip (Tulipa)

Tulip, as the national flower of the Netherlands, has countless articles praising it.

However, it turns out that both its flowers and leaves contain alkaloids that the human body cannot break down. If you place it in a relatively enclosed room, there may be a risk of dizziness and mental fog, and of a large amount of hair follicle loss.
