Good news for those who like a midday snooze; a nap may help to lower blood pressure. Researchers at the Asklepieion General Hospital in Voula, Greece, carried out a study, which looked at 212 participants with an average age of 62 and an average blood pressure of 129.9 mmHg. The researchers assessed and recorded blood pressure for 24 hours consecutively, as well as midday sleep time, lifestyle habits such as alcohol, coffee and salt consumption, physical activity levels, and pulse wave velocity, which is a measure of stiffness in the arteries.
