Sleeping near plants is generally not bad for your health. While it is true that many plants release carbon dioxide at night, the amount they produce is typically very small and not enough to be harmful to humans. Even if you have several plants in your bedroom, the cumulative amount of carbon dioxide they release is unlikely to reach levels that would be detrimental to your health.

It’s important to note that humans actually produce carbon dioxide when they exhale, and the concentration of carbon dioxide in a room can increase when there is poor ventilation. However, this is usually not a concern in well-ventilated spaces, and plants can actually help to improve indoor air quality by absorbing carbon dioxide during the day and releasing oxygen through the process of photosynthesis.
In terms of plant selection, some plants are known to release more oxygen at night than others. For example, snake plants (Sansevieria) and aloe vera are known for their ability to release oxygen at night, which can potentially improve sleep quality. On the other hand, certain plants like orchids and succulents primarily release carbon dioxide at night.
In conclusion, as long as you have good ventilation in your bedroom and a reasonable number of plants, sleeping near plants is not bad for your health. In fact, having plants in your bedroom can have positive effects on indoor air quality and may even promote better sleep. However, it’s always a good idea to do some research on specific plants before bringing them into your bedroom to ensure they will not release any substances or fragrances that might disturb your sleep.
