Now this does actually make sense as it's in a north-facing
bedroom.
Reason
for this? Because aloe vera gives off oxygen during the
night -
apparantly
most plants do this during the day - so aloes are
recommended as
bedroom
plants! I'm going to have to forego my oxygen to save my
plant!



Buy a different plant "~)

Here's a book that lists various other options :

Yes, I've already got this book - it's very good.
Going back to my aloe vera - it looks nothing like the one in
this book
which has broad "leaves" growing at 90 deg. to each other. Mine
has very
thin spikes growing at 180 deg. It was labelled as an aloe vera!
But
none of
the pictures I see ever resemble it!

Might it perhaps be an Agave ???

I've just done a Google image search on Aloe Vera and the images
that came
up included varieties which had the broad leaves and ones with long
spikes
at 90 deg. The image which seems to resemble mine is this one:

I've also had a look in the book mentioned above for other
possibilities to
get oxygen at night in my north-facing bedroom - seems as though the
snake
plant might be the one.

Datsy, let's do a little sum:
Give or take a factor of ten, the amount of Oxygen released in 24
hours will be comparable with the mass of plant material produced in
24 hours.
Your aloe would grow less than 1 gm of dry plant matter in a day, so
it
might be expected to produce less than 1 gm of Oxygen per day. The
density of Oxygen is around 1 gm per litre. So your plant will
produce something less than 1 litre of Oxygen overnight. That is
about one lungful. (All give or take a factor of 10, as I said). You
would
get much more than 1,000 times as much Oxygen into your room by the
simple expedient of sleeping with an open window.
