Breathing is something you do all day long,without even thinking about it.However,you might
be doing it wrong.Research shows that the way you breathe affects the amount of oxygen()you
take in,as well as how you think and feel.
So which is it Do you breathe through your nose or your mouth Some health experts
recommend people breathe in through the nose and out through their mouth.Others say that people
should just focus on breathing easily,paying no attention to their mouth or nose preference.But
mouth breathing has also been connected with bad breath,high blood pressure and bad teeth.
Nose breathing may improve how memories are stabilized (in our brains,according to
Swedish researchers.During the study,participants smelled 12 different smells and they were asked
to breathe either through their nose or mouth for an hour afterwards.Then,they were presented with
the original set of smells and a new set.Those who smelled with their nose remembered the smells
better.
A research team recognized the differences in brain activity that happened when seven epilepsy
(patients breathed through the nose or through the mouth.The team found three areas of the
brain where activity is connected with breathing.These areas showed more changes in brain activity
only when volunteers breathed in through their noses.
So,should people breathing through the mouth change their breathing habits If you're happy
with the way you breathe and you aren't experiencing any health problems,be yourself and just keep
your own way.But if you think it might be time for a change,focus on breathing through your nose
until it becomes a habit.It might help you survive an emergency.
