Yes, the peepal tree releases oxygen at night. The sacred fig, also known as the peepal tree or Ficus religious, is native to India and is considered a holy tree with numerous medicinal properties. One of the popular beliefs associated with the peepal tree is that it releases oxygen even during the night.

Trees typically release oxygen as a byproduct of photosynthesis, a process in which they use sunlight, carbon dioxide, and water to produce glucose and oxygen. During the day, when sunlight is available, trees actively engage in photosynthesis and release oxygen as a result. However, during the night, photosynthesis ceases as there is no sunlight for the process.
While most trees do not release oxygen at night, the peepal tree is an exception. It is believed to perform a unique kind of photosynthesis known as Crassulacean Acid Metabolism (CAM), which allows it to continue releasing oxygen even in the absence of sunlight.
CAM photosynthesis is a carbon fixation pathway that evolved in certain plants living in arid conditions. It involves the uptake of carbon dioxide during the night when the stomata (tiny openings on plant leaves) are open, minimizing water loss due to evaporation. This captured carbon dioxide is stored as malic acid in specialized cells within the plant. During the day, when the stomata are closed to prevent water loss, the stored malic acid is broken down, releasing carbon dioxide and allowing the plant to continue the process of photosynthesis and oxygen release.
The peepal tree’s ability to perform CAM photosynthesis makes it unique among other trees, as it continues to release oxygen even during the night when many other plants rely on cellular respiration and consume oxygen. This exceptional quality of the peepal tree has contributed to its reputation as a prolific oxygen producer, making it highly regarded and considered beneficial for the environment and human well-being.
It is important to note that while the peepal tree is known for its oxygen-releasing capabilities, the amount of oxygen released at night may be relatively lower than during the day. The exact contribution of the peepal tree to oxygen production, especially during nighttime, compared to other trees and vegetation, may vary based on numerous factors such as tree size, environmental conditions, and local air quality.
In conclusion, the peepal tree, or Ficus religious, is believed to release oxygen even at night due to its ability to perform CAM photosynthesis. While most plants rely on daylight for photosynthesis and oxygen release, the peepal tree’s unique adaptation allows it to continue the process during the night as well. However, further scientific research and studies may be required to precisely quantify and understand the nighttime oxygen-releasing capabilities of the peepal tree.
