Roadmap/06 - Activities

Lifestyle and activities that support metabolic health beyond diet: light, breathing, movement, and social contact. If you're not sure what to do with your time, pick something from the categories below.

Daily rhythm

Peat's advice on light, food timing, and stress reduction adds up to a simple daily template. The point is to avoid the two things that push the body into the stressed, glycolytic state described in Basics: prolonged blood-sugar drops and mistimed light exposure.

• Get morning light soon after waking. Natural sunlight, or a bright incandescent/red light if it's dark or cold outside, shortly after getting up. Peat linked light exposure to metabolic and mood effects directly:

  Light, play, environmental variety and exploratory conversations stimulate the whole organism in an integral way, stimulating repair processes and developmental processes.

• Eat soon after waking, don't start the day fasted. Blood sugar falls overnight, and in a hypothyroid person adrenaline and cortisol rise to compensate, peaking around dawn; eating breakfast is what brings those stress hormones back down. See Diet: Meal timing and blood sugar for the physiology.
• Don't let long gaps open up during the day. A long midday gap without food lets blood sugar drop and the same stress-hormone response kicks in as with skipping breakfast. Smaller, more frequent meals keep the digestive system working and avoid this; see Diet: Frequency.
• Get outside and move at some point in the day, ideally around midday when light is brightest. A walk works better for this than it might seem:

  A walk through interesting and pleasant surroundings consumes more energy than does harder but more boring exercise.

  — Ray Peat

• Build in something relaxing and something meaningful, beyond whatever's merely productive. Chronic low-grade stress from an over-scheduled, joyless day suppresses metabolism the same way dietary stressors do; see the stress cascade in Basics. A day with no unstructured, enjoyable time in it is still a stressful day even if nothing goes wrong.
• Wind down before bed rather than staying wired into the evening. Avoid bright blue-heavy light (screens, overhead LEDs) late at night; incandescent or red light in the evening is gentler on the systems that regulate sleep onset. See Sleep for more.

Adapt the timing to your own schedule; the important part is the shape of it: light and food early, activity and something enjoyable through the day, wind-down at night. Skipping a meal or missing light exposure and trying to compensate later defeats the point.

Social

• Spend time with people you trust
• Make new friends
• Do (or get someone to do) something you've been putting off out of fear or avoidance
• Call or visit family (eg. grandma)

Therapeutic

• Sit under a chicken/brooder incandescent infrared lamp: see Red light
• Buteyko breathing or bag breathing: raises body CO2, improving oxygen delivery to tissue via the Bohr effect
• Donate blood: lowers stored iron and unsaturated fat levels in the blood; Ray Peat pointed to it as a way to lower excess iron, and a randomized trial of iron-reduction phlebotomy found lower cancer risk and mortality in a peripheral arterial disease population, though that is a specific patient group, not a general-population result.
• Sauna: a 20-year Finnish cohort study found regular sauna use (4-7x/week vs. 1x/week) associated with a 66% lower risk of dementia and 65% lower risk of Alzheimer's; increased BDNF is one of several proposed mechanisms (alongside cardiovascular effects and reduced neuroinflammation), not an established cause.
• Chew mastic gum
• Basic skincare

Outdoors

Walking is a better form of exercise.

— Ray Peat

• Walk in a natural area: a Stanford study found that a 90-minute walk in nature (vs. an urban environment) reduced activity in a brain region linked to rumination and depression, and walking overall is associated with reduced all-cause mortality risk
• Sunlight: free, supports vitamin D production, and Peat linked it directly to mood:

  Sunlight can cure depression & increase intelligence.

  — Ray Peat

• Grounding / walking barefoot on grass
• Hike, ruck, or camp
• Time at higher altitude, occasionally
• Gardening or tending plants

Creative

• Any hands-on creative outlet as a low-stress way to externalize and process thought
• Crafting (knitting, sewing, crochet): in one survey, the large majority of participants reported feeling calmer, happier, and more accomplished afterward
• Photography, painting, or drawing
• Writing: journaling, poetry, short fiction
• Playing music or humming:

  Every time you make sounds on a musical instrument, you are stimulating organized processes in your body, it's a kind of nourishment.

  — Ray Peat

  Bhramari (humming) pranayama specifically has been shown to improve heart-rate variability and reduce stress more than physical activity, emotional stress, or sleep in one study

Manual

• Woodwork
• Chop wood
• Build something with your hands

Sport

Concentric resistance training has an anabolic effect on the whole body.

— Ray Peat

• Concentric resistance training: see Bodybuilding & Weight loss
• Friendly sparring for technique:

  I don't think martial arts are necessarily too stressful.

  — Ray Peat

• Short sprints:

  Sprinting is probably o.k.

  — Ray Peat

• High-intensity interval exercise: sensorimotor cortex GABA rose 20% after a session in one study, correlated with the rise in blood lactate
• Swimming

Animal

• Spend time with a pet, or consider adopting one from a shelter
• Walk a dog: dog ownership has been associated with a 40% lower risk of dementia in observational studies, likely partly through more time outdoors and more daily walking (slow walk after meals increases motility)

Mobility

• Stretching and posture work: address stiffness and misalignment directly rather than waiting on diet and hormone changes alone
• GOATA: a movement-correction system built on slow-motion analysis of natural movement patterns; no clinical studies behind it yet, treat it as a cheap, reversible practical tool rather than a proven protocol
• Foam rolling or self-massage: a two-week daily heat-plus-massage protocol lowered serum cortisol and norepinephrine versus baseline in healthy adults
• Regular walking barefoot on varied terrain to rebuild foot strength, see Walking and the Outdoors section above

Mentally challenging

• Play chess or another strategy game
• Read: see the reading list and Library
• Learn a new skill:

  Cytochrome oxidase in the brain can also be increased by mental stimulation, learning, and moderate exercise.

  — Ray Peat

Relaxation

Warmth and quiet support relaxed, efficient breathing; noise and cold push the system toward the stress cascade described in Basics.

• Quiet time, or listening to music
• Yoga: one small study found a single session increased brain GABA levels by 27% immediately afterward, versus no change in a reading-session comparison group, with other studies reporting reduced anxiety and depression in women
• Tai chi:

  Some of those who claimed extreme longevity practiced controlled breathing and tai chi (involving imagery, movement, and breathing), typically in the early morning hours, when stress reduction is most important. As far as I know, there are no studies of carbon dioxide levels in practitioners of tai chi, but the sensation of warmth they typically report suggests that it involves hypoventilation.

  — Ray Peat

• A good night's sleep
