Systolic and diastolic blood pressure, heart rate, and peripheral oxygen saturation (SpO\n                      <jats:sub>2<\/jats:sub>\n                      ) were measured after 20\u2005min of seated rest before showering, at the first post-shower measurement obtained within 5\u2005min of shower completion, and every 5\u2005min thereafter for 60\u2005min.
