Shape Of Nose Depends On Local Climate; Study Finds Warmer Climate Equals Wider Nose?
A recent study suggests that the nose is shaped not just by genes but also by the climate. The climate factors are, specifically, humidity and temperature.
According to a report, researchers studied the shape of the nose using three-dimensional images of different people. It is indicated that while studying these different groups of people, the local climate had a lot to contribute in the shape of the nose.
The researchers found that wider noses were found in climates that were warm and humid. For those who have narrower noses, it has been found that they come from a place where cold and dry climates are prominent.
It is indicated in the same report that the nose's primary functions are for the person to smell and breathe. The mucous and blood capillaries that can be found inside the nose help in warming and humidify inhaled air before it reaches the nose's sensitive parts.
A report indicated that the research gathered people from four populations. These were the North Europeans, South Asians, East Asians and South Africans. As the researchers studied these data, they found out that there is a difference in measurement from the width of the nostrils and the base of the nose across populations.
This result is more accounted for than the genetic attributes of the person. Additionally, the researchers also explored on how local climate may have contributed to the shape of the nose. They found out that the width of the nostrils is related to temperature and humidity of an area where the person is.
Meanwhile, a report indicated an important factor, the function of the nose goes beyond breathing and smelling. It warms the air that enters the body before it reaches the lungs. It is very important to have the right humidity and temperature for the respiratory tract. The researchers also hope to look into noses from other populations in the future.
