  • Why is it not good to sleep under a tree at night?

  • Hey.

  • You look so tired.

  • Why don't you take rest here?

  • No.

  • Please don't sleep under that tree.

  • It is quite harmful.

  • See, you are not able to breathe properly, right?

  • Do you know why?

  • Wait, I will tell you.

  • This is because during the day, in the presence of sunlight.

  • Plants take in carbon dioxide and release oxygen in the process of photosynthesis.

  • However, they even respire simultaneously.

  • In this process, plants take in oxygen and release carbon dioxide.

  • But the production of oxygen is more than the production of carbon dioxide.

  • Hence, if we sleep under a tree during daytime.

  • We may get a good amount of oxygen, thus giving us a nice sleep.

  • However, at night, plants do not perform photosynthesis due to the absence of sunlight.

  • But respiration still goes on.

  • Hence, as compared to oxygen, the proportion of carbon dioxide around the trees is more.

  • Thus, if we sleep under a tree at night, we may feel suffocated due to lack of oxygen.

  • Moreover, inhalation of excess carbon dioxide is harmful to human beings.

  • Therefore, it is not good to sleep under a tree at night.
