A new study shows that people living near the equator are at a higher risk of developing asthma and allergies.
According to scientists, the matter is not in the amount of pollen, but in ultraviolet rays, the level of which is increased in areas located closer to the equator. This increase may be due to vitamin D levels, which are believed to modify the immune system. These changes can lead to an increased risk of allergies and asthma.
Previous research has shown that latitude can affect airborne allergens due to climate, population, and social and cultural differences. This study is one of the first to link human location and UV exposure to allergies and asthma.
Allergies and asthma are serious medical conditions that can be life-threatening if not diagnosed and treated properly.
