Lifestyle: what peer-reviewed studies say each one helps with, and how strong the evidence is.

Acupuncture — Acupuncture may reduce migraine attacks and ease chronic back pain, with gains over sham (fake) needling that are real but small.
Aromatherapy — Inhaling essential oils may modestly improve sleep, anxiety and low mood, and sleep is the most consistent finding.
Balance Training — Balance and functional exercise probably reduces falls in older adults, by about a quarter in large reviews.
Breathing Exercises — Slow breathing at about 6 to 10 breaths a minute lowers blood pressure a modest amount in pooled trials, and short trials report less anxiety and stress and be…
Carnivore Diet — Small, uncontrolled studies suggest some people lose weight and improve their blood sugar on an all-meat, plant-free diet, at least in the short term.
Cold Water Immersion — Cold water immersion eases delayed-onset muscle soreness and perceived fatigue over 24 to 96 hours after strenuous exercise.
Dancing — Dancing is linked to better balance, mobility and mood in older adults, but trials disagree on whether it prevents falls.
Exercise and mental health — Exercise eases depression symptoms in randomised trials, and active people are less likely to develop depression.
Foam Rolling — Foam rolling may ease muscle soreness after exercise, with a small effect that shows up mainly after 24 hours.
Grey Hair — Premature greying is common, usually inherited, and linked to smoking and to some treatable deficiencies.
HIIT (High-Intensity Interval Training) — High-intensity interval training (HIIT) raises fitness more than doing nothing, and reviews show it may also lower blood pressure, waist size and blood sugar i…
Heat Therapy — Heat wraps may ease acute back pain and muscle soreness after exercise for a short time.
Hot Bath — A warm bath or shower roughly 1 to 2 hours before bed helps you fall asleep faster in the studies so far, and large studies of older adults link evening bathin…

Isometric Exercise — Isometric exercise — holding a contraction without moving, such as a handgrip squeeze or a wall sit — lowers resting blood pressure: pooled trials find drops o…
Journaling — Expressive and gratitude writing give small, lasting relief from stress and low mood in several trials.
Massage — Massage may ease low back pain in the short term and reduce muscle soreness after hard exercise, with some signs of lower anxiety and work stress.
Meditation — Mindfulness-based meditation programmes have the best-supported benefit for stopping depression from coming back: in pooled trials, relapse risk was about 31%…
Morning Light — Bright light, often taken in the morning and usually from a light box, helps lift depression and improve sleep in meta-analyses of clinical trials, and more da…
Music — Listening to music at bedtime improves how well people with sleep problems rate their sleep, and music also eases stress and anxiety in many trials.
Napping — Short daytime naps of 10 to 60 minutes are linked to better alertness, mood and short-term thinking in small trials, most of them run in laboratories.
Nicotine — As a medicine, nicotine's best-supported benefit is helping smokers quit: patches, gum and other forms raise quit rates by 50% to 60%.
Pet Ownership — Dog owners have lower death rates in large observational studies, and time with pets eases stress and anxiety in the short term.
Pilates — Pilates eases chronic low back pain more than minimal treatment, according to several reviews of randomised trials.
Progressive Muscle Relaxation — Progressive muscle relaxation (PMR) improves sleep quality and eases anxiety in pooled randomised trials, with a moderate level of evidence.
Sauna — Regular sauna use is linked to a lower risk of heart-related death, stroke and dementia in large Finnish studies, and small trials and meta-analyses of heat th…
Sleep — Expert panels advise 7 to 9 hours of sleep a night for adults.
Spinal Manipulation — Spinal manipulation eases back pain and improves function by modest amounts, with results similar to recommended treatments for chronic back pain.
Strength Training — Strength training builds muscle and strength, and trials show it eases depression symptoms and chronic low back pain and lowers blood sugar in type 2 diabetes.
Swimming — Swimming and other water exercise lower blood pressure in trials — systolic pressure falls by roughly 4 to 9 mmHg, with the biggest drops in people who already…
Tai Chi — Tai chi is linked to fewer falls in older adults in a meta-analysis of 24 trials, though one trial found no effect.
Time in Nature — Time in green spaces and nature is linked to lower stress and better short-term mood, forest visits lower blood pressure a little, and forest trips raised natu…
Walking — Walking after a meal lowers the post-meal blood sugar rise: pooled crossover trials found walking soon after eating cut glucose more than sitting or walking be…
Yoga — The strongest evidence is for easing chronic low back pain: reviews of randomised trials found less pain and better function than no exercise, though the effec…
