Top 9 Plants that release oxygen at night as well


If you’ve ever spent time in or near these settings, you’ll know how refreshing and revitalizing they are!

The biggest benefit to incorporating these oxygen-producing plants into your longevity lifestyle is going to be the improvement of air quality in your home.

Here are 9 plants that give off oxygen at night as well.

Areca Palm



Neem Tree (Kohoba)


Snake Plant



Aloe Vera


Gerbera (Orange)



Chrismas Cactus


Rama Tulsi, Tulsi ( Green)


Peepal Tree






Most plants largely uptake Carbon dioxide (CO2)and release oxygen during the day (photosynthesis) and uptake oxygen and release CO2 during the night (respiration).

Above plants can uptake CO{-2} during the night as well because of their ability to perform a type of photosynthesis called Crassulacean Acid Metabolism (CAM).

There are 2 pathways in photosynthesis.

Light reactions where O2 is released by splitting H2O.

Dark reaction (Calvin Cycle) where CO2 is used to make sugars

The energy to drive these reactions come from sunlight. CO2 is absorbed via stomata, and O2 is released by the same stomata.

In CAM photosynthesis or Crassulacean-Acid metabolism, the plant opens the stomata at night to minimize water loss. CO2 is acquired at this time and stored in vacuoles as malate.
