| Measure | Time frame |
|---|---|
| 3 trials per participant on separate days. 1. Breathing exercises + no media equipment 2. Breathing exercises 3. Control (1) Height, weight, body fat percentage, and body mass index will be measured. (2) Arterial stiffness, blood pressure, heart rate, and autonomic nervous system function will be measured before and 30 and 60 minutes after the 4, 4, and 8 breathing exercises (no breathing exercises and seated rest for trial 3) for trials 1 and 2. (3) Daily life while measuring autonomic nervous system function, body movement, and step count with a heart rate sensor. 4, 4, and 8 breathing exercises will be performed every hour until 17:00 for trials 1 and 2, and one hour before bedtime (trial 3 will not be performed). (4) During bedtime, autonomic nervous system function, body movement, and blood pressure (at 2:00 and 4:00 a.m.) will be measured using a heart rate sensor and a wrist sphygmomanometer, respectively. (5) In the morning of the next day, arterial stiffness, blood pressure, heart rate, autonomic nervous system function, and concentration will be measured. | — |
