You can put some: pothos, aloe vera, commelder grass, purple bamboo grass, hyacinth, spider plant, aloe vera, asparagus, crab claw orchid, kidney fern, maidenhair fern, phoenix fern and other ferns . However, one thing to note is that the plants placed in the bedroom should choose shade-loving plants, because indoor sunlight is not as good as outdoor, and the growth of plants is affected by light. The better the light, the better they will grow. In addition, it is recommended to move the plants to the balcony or living room before going to bed at night, because although plants perform photosynthesis during the day (photosynthesis: plants absorb carbon dioxide and release oxygen when there is light, usually during the day) ), but what happens at night is respiration (respiration: plants inhale oxygen and release carbon dioxide when there is no light, usually at night), and they compete with people for oxygen.
