Why peepal tree releases oxygen at …

During the day, in presence of sunlight, the plants use up the CO₂ and release O₂  in the process of photosynthesis. But during night, plants won’t perform photosynthesis so they are unable to use the CO₂  and this further leads to increase in the proportion of CO₂  in the air. During night the trees breathe in oxygen and release CO₂ . If one sleeps under the trees, the amount of increased CO₂ in the air around will certainly affect the health. So it is inadvisable to sleep under trees during night. He suffers from suffocation. He feels excess weight on his chest. For this reason, some rural people imagine and fear that ghosts would come and sit on their chests if they sleep under Peepal or Banyan trees.
