Explanation

During the day, in presence of sunlight, the plants use up the carbon dioxide and release oxygen as a byproduct. But during night they are unable to use the carbon dioxide and this leads to increase in the proportion of carbon dioxide in the air. During night the trees breathe in oxygen and release carbon dioxide. If one stands under the trees, the amount of increased carbon dioxide in the air around will certainly affect the health. So it is not inadvisable to stand or sleep under trees during night.
