Breathing is the only function of the autonomic nervous system you can reach by will. A meta-analysis of 223 studies shows that the rest-related part of heart rate variability rises during and after slow breathing. Breathing slower than 10 breaths per minute has also been linked with a calmer emotional state.
In a 2023 study, five minutes a day of breathing with a long exhale went along with a positive change in mood after one month.
Each card shows what the study actually found, and its limits.
A systematic review linking breathing slower than 10 breaths per minute with higher heart rate variability and a calmer emotional state.
Limitation: Only 15 studies, and they differ widely.

A randomized study in which five minutes a day of breathing with a long exhale went along with a clearer positive change in mood over a month than the same time of mindfulness meditation.
Limitation: About 100 participants, conducted remotely, lasted one month.

A meta-analysis of 223 studies finding that the rest-related part of heart rate variability rises during and after voluntary slow breathing.
Limitation: A physiological finding; it does not measure mood or anxiety.

A meta-analysis of 47 randomized trials finding small to moderate effects of mindfulness meditation programs on anxiety, low mood and pain.
Limitation: Not found superior to other active approaches such as exercise.
