1. Carefully raise flowers with strong aroma

People spend a long time in flowers with too strong fragrance, which will inevitably bring some negative effects to people's body. For example, most flowers such as roses and Narcissus are just the first to smell fragrant and refreshing. Over time, people will only feel dizzy and even have a little nausea, and may cause asthma, pharyngitis, allergic rhinitis, cough and other diseases. This situation will only be more serious. It will not be said that people will not have an impact if they adapt to that environment. The smell of flowers in the air is too strong, and the relative reduction of oxygen content will stimulate people to breathe excessively, reduce the oxygen content in the blood, and have adverse reactions such as headache, dizziness and nausea. For example, if you smell too much orchid fragrance, you will feel dizzy; Lily fragrance time will also lead to dizziness and even insomnia

If there are many flowers and strong aroma in the room, and then the space is not well ventilated, some people will even suffer from "hypoxia". During the day, it is prone to chest tightness, shortness of breath, poor breathing and other adverse reactions. Poor rest also occurs at night. Lack of air leads to poor sleep and insomnia. In the long run, the original intention of raising flowers is the opposite, but as long as such flowers are not cultivated indoors, there will be no such concern

2. Carefully raise flowers suspected of allergy

Pollen allergy is the most harmful to human body. The smaller the pollen particle, the more serious the allergy will be. Generally, most of the plants that cause people's allergies are outdoor plants, but indoor cultured flowers may also cause allergies. They can cause people to have allergic symptoms through direct or indirect contact, such as eye itching, nose itching, ear itching, pharyngeal itching, skin itching and so on. Therefore, it is necessary to carefully select cultivated flowers

3. Be careful to raise poisonous flowers

Some flowers are toxic to humans and have adverse reactions to humans through odor, juice and other means. In particular, the juice of some flowers, once exposed to, will cause skin allergy, redness and itching to the human body, and will have terrible consequences on the human body, such as diarrhea, blindness and so on. If people have high blood pressure and heart disease, it is only harmful to their health, not beneficial. In addition, for people with children at home, toxic flowers should be placed out of the reach of children, or directly choose other safer flowers
