The photo is from an Apartment Therapy post about the urban legend of houseplants being harmful to people during the night. I know of no evidence to support this myth.
In my view, a point was missed here. The problem here is not plants in bedrooms it's these particular plants, both of which are 'anorexic.' Simply put they are light starved and not in good health.
The plant on the left is a Dracaena marginata and the one on the right is a Crassula (Jade Plant). The drooping leaves and spindly stems on both plants exhibit classic symptoms of light deficiency.
The solution is simple. Measure the light with a foot-candle (or lux) light meter. If inadequate, provide more light and sub-irrigate the plants.
