The links and material on this page are provided to summarize findings about the effects of vog on health.
How vog affects human health is the topic of active research. Children and those with pre-existing lung conditions are the most vulnerable to its effects. Some studies show that children and those with pre-existing respiratory problems are more likely to visit a medical clinic or emergency room during vog episodes. Although vog exposure has not been shown to cause childhood asthma, it has been shown to aggravate asthma in those already diagnosed with the condition.
When exposed to vog, some people report eye, nose, throat, and/or skin irritation, coughing and/or phlegm, chest tightness and/or shortness of breath, headache, and increased susceptibility to respiratory ailments. Some people also report fatigue and/or dizziness. One researcher also found vog is associated with high blood pressure. Another researcher found a link to anxiety.
