When you hold your breath the ongoing accumulation of carbon dioxide in your cells, in your blood and lungs will eventually irritate and trigger impulses from the respiratory center part of your brain. Rising levels of carbon dioxide signal the body to breathe and ensure our unconscious and autonomous respiration.
The Brazilians celebrate the Valentine's Day in a very big way. Unlike in the United States or any other countries, Brazil does not celebrate Valentine's Day on the 14th of February because it usually falls close to the Brazilian Carnival. They celebrate the Dia dos Namorados (Day of the Enamored) on June 12th.
Other Latin American countries celebrate similar days of friendship and affection like Valentineâs Day, but not necessarily in February. Colombia, for example, celebrates Valentineâs Day on September 20th when it popular to send gifts from secret admirers. Bolivia also favors September by celebrating the âDÃ­a del Amorâ on September 21st in conjunction with Studentsâ Day, Day of Spring and Childrenâs Day. â
