There's a belief that it is inadvisable to have plants in the bedroom. The concern is about how plants breathe. While plants take in carbon dioxide and release oxygen in the day, at night this is the opposite. But to tell whether sharing our bedroom with our plants is a risk to health,
we have to consider three things.
This is tricky to answer as it depends on everything from species to light levels and even room temperature, Also, there's not much research on the exact measurements in indoor settings. Thankfully, in 2015, researchers at Turkey's Kastamonu University found that houseplants like ficus(榕树) and yuccas(丝兰), when sealed(密封) in glass boxes, absorb between six and eight times as much CO2 in the day as they emit at night. This results in a significant net reduction over a full day.
Secondly, we should compare the impact of plants on air quality with that of other potential competitors, such as a partner, A single human breath contains around
40.000ppm of CO2, more than 10 times the effect a plant could have in 8 hours. Also, consider this. Indoor plants grow in less light than they would ideally get in nature. So, they photosynthesize(光合作用) at a lower rate. This further reduces their impact on air quality.
Finally, it is obvious that we don't live in the sealed boxes in which these studies are carried out. Even our movements can influence its flow.
In conclusion, the plant effect in our homes is very small in many ways. If sleeping near plants were bad for your health, camping in a forest would be definitely deadly.
A. Firstly, how do plants breathe at night?
B. So enjoy houseplants whenever you like.
C. Firstly, do plants emit more CO2 at night?
D. Camping can be a good escape if you are worried.
E. This means they compete with us for air when we sleep.
F. Indoor air is constantly exchanged through doors and windows.
G. So you might want to send your partner away before your plants.
