During the day, in presence of sunlight, the plants use up
the CO2 and release O2 as a byproduct.But during night they
are unable to use the CO2 and this leads to increase in the
proportion of CO2 in the air.During night the trees breathe
in oxygen and release carbon-dioxide.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
sit under trees during night.
