This 2002 review looked at animal and human research on exercise and the brain. It reports that voluntary exercise in animals raises levels of brain-derived neurotrophic factor (BDNF) and other growth factors, spurs the birth of new neurons, changes gene activity in ways that support plasticity, and can improve learning…
This 2011 review looked at many studies on mindfulness and mental health. It defines mindfulness as paying attention in the present with nonjudgmental acceptance and says this involves both focusing attention and an open, curious attitude. The authors examined three kinds of research—correlational studies, intervention trials, and lab experiments—and concluded…
This review defines self-compassion as being supportive toward yourself during suffering and presents a six-part model (more self-kindness and common humanity and mindfulness; less self-judgment, isolation, and overidentification). It summarizes a growing set of empirical studies that suggest self-compassion helps people handle distressing thoughts and emotions and is linked to…
Mindfulness-based interventions (MBIs), especially Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy (MBCT), teach people to pay nonjudgmental attention to the present moment. Reviews and randomized trials show MBIs can reduce anxiety and depression symptom severity across many groups, often doing better than non-evidence treatments or active controls and performing…
The source explains what Acceptance and Commitment Therapy (ACT) is and reports research comparing ACT with cognitive therapy (CT). In a randomized trial of 101 outpatients with moderate to severe anxiety or depression, people assigned to ACT or to CT showed large, similar improvements in depression, anxiety, daily functioning, quality…
This review combined results from 10 intervention studies to see if physical activity programs change cortisol (a stress hormone) and sleep in adults. The pooled results found lower cortisol after activity programs and some improvement in sleep quality. The authors say the evidence is moderate for cortisol and low for…
This 2022 systematic review and meta-analysis pooled data from 223 studies to see if voluntary slow breathing (VSB) changes heart rate variability that reflects parasympathetic (vagal) control of the heart. The authors found that VSB increased vagally-mediated heart rate variability during breathing sessions, right after a single session, and after…
This paper pooled results from 19 randomized trials with 1,173 adults to see if meditation and yoga change PTSD symptoms. Overall, these mind–body practices were linked to a small-to-medium reduction in PTSD symptoms (effect size = −0.39). The authors found no big differences by type of practice, who was studied,…
This randomized study tested a breathing-based meditation (Sudarshan Kriya yoga) in 21 male U.S. veterans of the Iraq or Afghanistan wars. Participants were randomly assigned to the meditation group (n = 11) or a waitlist control (n = 10). The meditation group showed reductions in self-reported PTSD symptoms, anxiety, and…
This review looked at smartphone apps made for treating eating disorders. The authors found that research on whether these apps work is scarce. They also found that most existing apps include few proven treatment methods and do not use the special abilities of smartphones (like real-time interaction and sensors). The…
This randomized, controlled trial tested a brief cognitive behavioral therapy (CBT) program for 41 patients with chronic subjective dizziness. The program was three weekly sessions led by a clinical psychologist and used psychoeducation, behavioral experiments, exposure, and attention refocusing. After treatment, patients showed large, significant reductions in dizziness-related disability, physical…
This systematic review looked at clinical studies that paired psychedelics with a structured psychotherapy. It found that psychedelic-assisted psychotherapy can give promising results across many clinical conditions when given to carefully screened people in controlled settings, but some patients relapse or do not respond. The review highlights that individual and…
