Expatriate health insurance customers might be interested to learn that living in sunnier climates can reduce a child's problems related to asthma.
According to a team from Valencia, almost 90 per cent of people's vitamin D requirement is synthesised from the sun.
Children with asthma tend to present lower levels of the vitamin. However, the team found that those living in colder, wetter climates are at a greater risk of suffering from asthma than those in sunnier climates due to their restricted hours of sunlight.
Alberto Arnedo-Pena, an epidemiologist at the Public Health Centre in Castellon and lead author of the research, commented: "Although we need more studies on this issue – this hypothesis is not even five years old – it is clear that an average level of sun exposure is important for the assimilation of vitamin D, a compound that is extremely important in preventing illnesses such as asthma, tuberculosis and other infectious diseases."
