Some evidence. Some limits.

Goyal and colleagues (2014) review 47 randomised trials with 3,515 people. Dem find moderate evidence say anxiety reduce (effect size 0.38 at eight weeks) and depression reduce (0.30), but low or not enough evidence for attention, sleep and positive mood. These na programmes; dem no test this timer.

For one trial wey last one month, Balban and colleagues (2023) find say five minutes a day of cyclic sighing improve positive mood pass mindfulness meditation. No significant change happen for heart-rate variability or trait anxiety. One trial na reason to wonder, no be promise.
