Miami.- people who have habit breathing through the mouth instead of the nose A recent study conducted by a group of scientists has shown that can have serious consequences on your heart health. Florida State University,
heart conditions They are one of the leading causes of death in the United States. According to the American Heart Association (AHA), Approximately 82.6 million Americans currently suffer from one or more forms of cardiovascular disease (CVD).,
Among the most common heart diseases are Heart failure, hypertension or high blood pressure, myocardial infarction, In others. These are mostly caused by factors like poor diet, physical inactivity, tobacco and alcohol consumption.
However, this new research finds that inhalation may also be a major risk factor. To reach this conclusion, researchers evaluated 20 volunteers aged 18 to 30 without any heart disease.
They were asked to breathe through their nose or mouth for 5 minutes while resting or exercising on a treadmill or stationary bike. To measure heart rate, oxygen levels and blood pressure, and thus be able to compare variables between nasal and oral breathing.

Breathe through nose or mouth?
According to research recently published in the American Journal of Physiology, Using physiological nasal breathing instead of oral or mouth breathing can dramatically reduce the risk of heart disease and improve blood pressure.
The researchers found that resting volunteers had lower average diastolic blood pressure (the pressure inside the arteries between heartbeats) when they breathed through their nose.
The results showed that nasal breathing caused the body's nervous system to go into rest and digestion mode instead of remaining in fight-or-flight mode.
The team of experts said that this happened only during the break. No difference was shown between nasal and mouth breathing during the exercise.
So they came to the conclusion that nasal breathing, unlike oral breathing, Provides modest, but potentially clinically significant improvements in cardiovascular prognostic variables at rest, but not during exercise,
,What effect does breathing have on the heart?
The writers explained it Breathing patterns can affect blood pressure and heart rateA, which are two predictors of heart disease due to interference between the respiratory and circulatory systems.
“This work advances our knowledge of how nasal breathing affects clinically relevant cardiovascular variables,” said the team, led by Joseph Watso, assistant professor of human and health sciences at Florida State University in Tallahassee.
They highlighted that although nasal breathing relaxes the airways and improves breathing ability, its effects on cardiovascular health have not yet been fully explored.
“However, our results showed that other important predictive markers of cardiovascular health may be improved during rapid nasal versus oral breathing,” he said.
Progress towards resolving the issue
Wattso's team gave this assurance With these current findings, future work may address any potential relationships between these clinically relevant respiratory variables. and changes in cardiovascular health, as well as measuring additional variables.
“This fundamental data set in young adults This could be expanded to inform studies that examine whether cardiovascular disease is reduced in other groups such as obese adults or older adults. By applying a good respiratory method,” he explained.
He emphasized this with this work Advances in knowledge about how nasal breathing affects the cardiovascular system and provides important acute data in healthy young adults to justify future long-term studies in other populations.
