Dae it wirk for ye?

A wee bit evidence. Some limits.

Goyal and colleagues (2014) reviewed 47 randomised trials wi 3,515 folk. They fand moderate evidence for reduced anxiety (effect size 0.38 at eight weeks) and depression (0.30), but low or insufficient evidence for attention, sleep and positive mood. Thir were programmes, no a test o this timer.

In ae month-lang trial, Balban and colleagues (2023) fand that five minutes a day o cyclic sighin improved positive mood mair than mindfulness meditation. There wis nae significant change in heart-rate variability or trait anxiety. Ae trial is a reason for curiosity, no a promise.
