DAYLIGHT HOURS AND TEMPERATURE MAY BE LINKED TO HYPERTENSION

A recent study in Hypertension: Journal of the American Heart Association showed an association between blood pressure and both personal-level environmental temperature and increased daylight hours and blood pressure. Each 1 degree Celsius increase in personal environment was associated with a decrease in daytime systolic blood pressure, and each one hour increase in daylight was associated with an increase in nighttime systolic blood pressure. These relationships were only significant for those people already receiving treatment for existing hypertension. This could possibly have implications for future research and interventions during the winter months.
