This is the drawback of water evaporative cooling systems. It cools well and well, and even improssously if the air is dry; but that does not increase comfort that much ...
Where an air conditioning cools and dries up!
[for info, 23,8 ° tonight, house closed; always 31,5 ° outside]
Hello
the comfort zone is between 18 ° and 25 °,
above 25 °, the calories must be evacuated by evaporation, natural convection is no longer efficient enough,
. . . while sleeping, for example.
if we cannot evacuate the calories while sleeping by evaporation,
because the hygrometry is greater than 65% or 70%
(personal number felt),
we enter the overheating zone,
which will decrease muscle performance and weaken his general condition - while sleeping.
This is what kills, even if we are wet with perspiration
sweating is useless if there is no evaporation due to air saturated with water
