2. Avoid placing too much. At night, most flowers release carbon dioxide and absorb oxygen to compete with people. Most of the rooms at night are closed, and the air is not well circulated with the outside world. Excessive indoor flowers will reduce the indoor oxygen concentration at night and affect the quality of sleep at night, such as chest tightness and frequent nightmares.
3. Avoid putting poisonous flowers indoors. Such as oleander, its stems, leaves and even flowers are toxic in spring, summer and autumn, and its milky juice contains an oleanolide, which will be poisoned if eaten by mistake; The bulbs of daffodils contain Latin toxins, which can cause vomiting and other symptoms if children eat them by mistake. The juice of leaves and flowers makes the skin red and swollen. If the juice is eaten by mistake, it will hurt the eyes. Too much exposure to mimosa can easily lead to sparse eyebrows, yellow hair and serious hair loss.
