Långsam andning dämpar ångest utan mindfulness i studie på möss

En ny studie visar att en långsammare andningsfrekvens kan minska ångestliknande beteenden, även utan medveten ansträngning eller förväntan om effekt. Forskare använde möss för att visa att fördelarna uppstår genom fysiologiska förändringar snarare än placebo. Resultaten presenterades vid ett toppmöte i Los Angeles tidigare denna månad.

Jack Feldman, neuroforskare vid UCLA, presenterade forskningen vid Embodied Minds Summit i Los Angeles den 3 maj. Hans team tränade möss att andas långsammare med hjälp av optogenetik genom att rikta in sig på neuroner i pre-Bötzinger-komplexet, en del av hjärnstammen som styr andningsrytmen. Efter fyra veckor behöll mössen en långsammare andning och uppvisade mindre rädsla i stresstester jämfört med otränade möss.

Researchers working with the University of Auckland and Brazil’s University of São Paulo report that neurons in the medulla’s lateral parafacial (pFL) region—best known for helping drive forceful exhalations—also amplify sympathetic nerve activity and can raise blood pressure in an animal model of neurogenic hypertension. Inhibiting these neurons lowered blood pressure toward normal in hypertensive rats, findings published in Circulation Research.

A randomized clinical trial found that 24 minutes of specially designed music paired with auditory beat stimulation significantly lowers anxiety symptoms. Researchers at Toronto Metropolitan University tested various listening durations on 144 adults with moderate anxiety. The 24-minute session provided the strongest benefits.

New research from New York University indicates that anxiety about growing older, particularly concerns over health decline, correlates with accelerated cellular aging in women. The study, involving 726 participants, used epigenetic clocks to measure biological aging rates. Fears related to appearance or fertility showed no similar connection.

A new study in Gastroenterology connects early life stress to long-term gut issues through disruptions in gut-brain communication. Mouse experiments and large human cohorts show links to pain, constipation, and irritable bowel syndrome. Researchers suggest targeted treatments based on specific biological pathways.

Researchers at Monash University have found that adults with ADHD experience more frequent episodes of sleep-like brain activity during wakefulness, which correlates with attention lapses. The study, published in the Journal of Neuroscience, links these brief shifts to errors, slower reactions, and increased sleepiness during tasks. Lead author Elaine Pinggal suggests this mechanism underlies attention difficulties in ADHD.
