How we verify every claim

A one-month meditation-app pilot reported improvements in student anxiety, stress and sleep measures. A larger trial is needed; this does not validate EasyBreezyMind recordings.

Walking significantly reduced anxiety symptoms compared with inactive controls (26 RCTs, SMD −0.45), across different frequencies, durations, indoor or outdoor settings and group or solo formats.

A four-week online self-compassion programme improved self-reported self-compassion, wellbeing, stress and personal/work burnout compared with a waitlist. This does not validate a two-minute exercise.

Four weeks of guided breathing at about 5.5 breaths per minute did not outperform guided breathing at 12 breaths per minute on stress, anxiety, depression or wellbeing. Improvement within both groups does not establish benefit over no intervention.

In a remote randomized controlled study, 5 minutes a day of exhale-focused cyclic sighing for a month improved mood and lowered respiratory rate more than mindfulness meditation.

In adults with diagnosed anxiety disorders, an 8-week MBSR course was noninferior to the medication escitalopram. This describes a clinical trial, not a reason to change any treatment.

After a 5-minute cold-water immersion, participants reported more positive affect and less distress and nervousness, alongside changes in brain-network interaction.

Breathwork was associated with lower self-reported stress than control conditions (small-to-medium effect, g = −0.35), with similar effects on anxiety and depressive symptoms. The authors urge caution because most studies had moderate risk of bias.

Micro-breaks had small average benefits for vigor and fatigue, but no statistically significant overall performance benefit. The review did not pool anxiety outcomes or establish the best break activity.

Limiting Facebook, Instagram and Snapchat to 10 minutes a day did not significantly change students’ wellbeing or grades; participants shifted time to instant messaging instead.

Across 14 experiments, listening to music after a lab stressor did not produce a significant overall effect on stress recovery (g = 0.15); results varied by genre, tempo and who chose the music.

In people without anxiety at the start, there was no evidence that physical activity prevented anxiety (SMD −0.18, not significant), though the quality of evidence was very low.

A single session of deep, slow breathing reduced state anxiety and increased a heart-rate-variability marker of vagal activity in both younger and older adults, with a larger physiological change in older adults.

Twenty minutes of recorded progressive muscle relaxation, deep breathing or guided imagery all increased feelings of relaxation compared with a control group.

After two weeks, self-compassion writing reduced self-reported physical performance anxiety versus a waitlist. Cognitive performance anxiety did not significantly change.

Mental contrasting plus if–then planning had a small-to-medium average effect on goal attainment (Hedges’ g = 0.336). Publication bias may inflate the estimate; this is not evidence of anxiety treatment.

Eight weeks of guideline-based strength training significantly reduced anxiety symptoms compared with a wait-list (d = 0.85). Worry did not change significantly.

Sleep loss raised next-day anxiety, while deep NREM slow-wave sleep had an anxiety-reducing effect; even modest night-to-night sleep reductions predicted higher next-day anxiety.

Four weeks of 200 mg/day L-theanine reduced stress-related symptom scores and improved sleep-quality scores versus placebo in healthy adults.

In stressed healthy adults, 60 days of a standardized ashwagandha extract reduced anxiety ratings and morning cortisol versus placebo.

City dwellers who spent time in a place that felt like nature saw cortisol fall faster than its normal daily decline. The benefit per minute was greatest between 20 and 30 minutes.

In a virtual experiment, park and forest environments, but not an urban one, produced significant physiological stress recovery; pleasant smells seemed to matter more than visuals.

Slow breathing (under 10 breaths per minute) in healthy people was linked to higher heart rate variability and changes in nervous-system activity alongside psychological effects.

Aerobic exercise reduced raised anxiety compared with waiting-list control groups.

Yoga showed small short-term effects on anxiety compared with no treatment.

Novice meditators using a brief app-based mindfulness program improved in irritability, affect and stress from external pressure compared with an educational audiobook control (d ≈ 0.45).

Students with high test anxiety who wrote about positive emotions for 20 minutes a day for 30 days scored significantly lower on test anxiety than students who simply wrote down daily events.

Tai chi and yoga improved heart-rate-variability markers and lowered perceived stress (g = −0.80) across 17 medium-to-high quality trials.

HRV biofeedback training was associated with a large reduction in self-reported stress and anxiety (between-group Hedges' g = 0.83).

Evidence was suggestive of a benefit of magnesium on subjective anxiety in anxiety-vulnerable samples, but the quality of the evidence was poor.

Exercise reduced anxiety symptoms more than control conditions, with a moderate effect size.

After 20 sessions of diaphragmatic breathing over 8 weeks, healthy adults showed less negative affect, better sustained attention and lower cortisol, while the control group did not change.

In healthy people, MBSR was moderately effective at reducing stress, anxiety and distress.

A 90-minute walk in nature, but not in an urban setting, reduced self-reported rumination and activity in a brain region linked to it.

Explains how breathing at a person's resonance frequency (around 6 breaths per minute) produces large oscillations in heart rate and may strengthen baroreflex regulation.

400 mg of caffeine taken even 6 hours before bedtime significantly disrupted sleep compared with placebo.

Two weeks of a daily 30-minute, time- and place-restricted "worry period" reduced worry in people with high trait worry compared with a control condition.

Across 106 meta-analyses, the strongest support for CBT was found for anxiety disorders and general stress, among other problems.

Reviews how caffeine can induce anxiety at high doses, particularly in sensitive people, while moderate intake is generally well tolerated.

Relaxation training showed a medium-to-large effect on anxiety.

Summarizes studies in which writing about emotional experiences for short sessions was followed by improvements in wellbeing measures.

Introduced the concept of measuring perceived stress — how unpredictable, uncontrollable and overloaded life feels — which inspires our self-check (our items are our own).
