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 (氧气) you take in，as well as how you think and feel.
So which isit? 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 (稳定) 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 (癫痫) 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.
