Deliberate heat exposure using a sauna, typically around 80–100°C (176–212°F). Sessions are usually 5–20 minutes, with 10–20 minutes commonly emphasized, and frequency adjusted to tolerance and goals. The main rationale is to trigger a strong heat-stress response that supports cardiovascular conditioning, sweating, and overall resilience.

A cold-water immersion setup such as a plunge pool, cold tub, or ice bath used for deliberate cold exposure. The common protocol is a brief immersion in very cold water, often early in the day and done safely, to trigger a strong adrenaline/noradrenaline response and a dopamine boost. People use it for alertness, stress resilience, and sometimes soreness or recovery support, though it may not be ideal immediately after training if maximizing muscle growth is the goal.

Glasses designed to filter short-wavelength light from screens and indoor LEDs, typically worn in the evening after sunset or late at night. The common protocol is to use them during nighttime screen use or bright indoor lighting to reduce melatonin suppression, help keep cortisol lower, and make it easier to transition to sleep.

A fan-resistance air bike used for hard interval training, typically in short all-out efforts with brief rests or 30-seconds-on/10-seconds-off style work. It lets you drive heart rate and breathing very high while keeping the movement simple and relatively low-impact, which makes it a practical option for sprint and VO2 max sessions.

A warm soak in a hot tub or bath in the evening, typically for 20 to 30 minutes, followed by a cool or warm shower to help the body shed heat. The goal is to trigger compensatory cooling and lower core body temperature by about 1 to 3 degrees, which can make it easier to fall asleep.

Use a red bulb or very dim red nightlight in bedrooms and other evening spaces instead of bright white or blue-rich lighting, especially in the last hour before bed. The goal is to minimize blue-light exposure and reduce disruption to circadian signaling and nighttime cortisol, which can make it easier to fall asleep and stay asleep.

Wear a glucose sensor on the arm that measures blood sugar about every 5 minutes, typically for around 14 days per device and often used for a short learning phase of roughly 30 days. It helps you see how specific foods, sleep, stress, and other behaviors affect your glucose in real time, so you can identify your personal spike triggers and make more effective behavior changes.

Using a rowing machine for high-intensity interval training, often as a low-eccentric-load alternative to running or other impact-heavy conditioning. It’s typically programmed in vigorous intervals or mixed conditioning sessions, sometimes paired with assault bike work and lifting. The appeal is that it builds anaerobic capacity and conditioning while being easier on the joints and muscles than many other hard-effort modalities.

A red and near-infrared light therapy panel used at close range for a few minutes per session. The common protocol is about 10–15 minutes, 5–7 days per week, positioned roughly 1–2 feet away, with the goal of delivering long-wavelength light for skin quality and related photobiomodulation benefits.

Wear a weighted vest during walks, hikes, chores, or dog walks to make ordinary movement more demanding without adding extra time. A common starting point is about 10% of body weight, often around 8-12 pounds, with some people using heavier loads up to roughly 10-50 pounds depending on the activity. The added load increases effort and impact, which can help build strength and support bone density, especially for osteoporosis prevention.

Use a bright 10,000-lux light soon after waking when natural sunlight is unavailable, especially in darker seasons or for early indoor schedules. Place it nearby while you make coffee, journal, or get ready for the day for about 5–10 minutes rather than staring directly at it. The goal is to mimic morning daylight cues that help anchor circadian rhythm and improve alertness and mood.

A weighted training implement used for simple strength and mobility work at home, in the office, or in the garage. The common protocol is brief, frequent practice such as overhead presses, swings, or short timed sets done whenever it’s convenient. It builds strength, power, and range of motion while making it easy to accumulate exercise throughout the day.

A free app and website with short, clinically supported hypnosis scripts developed by Stanford colleagues. People use it for relaxation, focus, chronic pain, and especially a fall-back-asleep protocol when waking in the middle of the night, which helps quiet looping thoughts and ease return to sleep.

Use a bright artificial light or daylight simulator when natural sunlight is unavailable, especially in dark winter mornings or before sunrise. Turn it on soon after waking, or use it briefly before travel or to help shift your circadian timing. The goal is to provide a strong light cue to the brain’s circadian system, helping promote alertness and stabilize sleep-wake timing.

An inexpensive bright-light panel or drawing tablet used first thing in the morning when natural sunlight isn’t available. People place it on a desk, coffee station, or in a hotel room and use it for a short morning session to help anchor wake time, support circadian timing, and reduce the drag of dark mornings or travel disruptions.

Use an adjustable workstation that lets you switch between sitting and standing during the day, often aiming for roughly half the work time in each position. Raise the monitor so the screen is at about eye level while standing to keep posture neutral and reduce the tendency to slump. The main benefit is to break up prolonged sitting while supporting alertness and comfort during desk work.

Use a stationary bike as a low-impact cardio option when running or jumping irritate the knees, with resistance adjusted on the pedals to scale effort. The dominant use here is interval-style work such as short all-out sprints or Tabata sessions, which can build conditioning while reducing joint stress and still providing a strong aerobic and anaerobic stimulus.

Use a free light meter app on your phone to estimate ambient light levels in lux by pointing the device toward the light source or the area you want to assess. It’s a quick, back-of-the-envelope way to quantify brightness so you can compare rooms, check whether lighting is actually strong enough, and make more informed adjustments to support alertness or circadian timing.

Audio tracks are played so each ear receives a slightly different frequency, creating a binaural beat effect. The usual protocol is to listen with headphones, which is how the two tones are kept separate and the effect is most reliably produced. Different frequency ranges are commonly used for different states, such as delta-range beats for easing the transition into sleep.

A periodic DEXA scan used to measure body composition rather than relying on BMI or scale weight alone. It provides practical metrics like lean mass, bone mineral density, and visceral fat, making it useful for tracking changes over time and checking whether muscle mass is sufficient. It is often treated as the gold-standard assessment for body composition, even though it does not directly measure muscle quality.

A simple eye covering used during psychedelic-assisted sessions, especially psilocybin and MDMA therapy. The usual protocol is to put it on for most or all of the session so external visual input is minimized and attention can turn inward. This can reduce distraction from changing visuals and support a deeper, more introspective therapeutic experience.

A standardized hand- or palm-cooling method used during rest periods in training or endurance efforts. The usual protocol is to hold a cool object such as a mitt, gel pack, cold water bottles, or a chilled can in the palms long enough to feel cool but not ice-cold. The goal is to help manage heat stress and preserve performance by cooling blood passing through the hands without triggering the vasoconstriction that can come from very cold exposure.

Use wearables or sleep devices like Oura, Whoop, or Eight Sleep to monitor sleep patterns over time, including stages such as REM and slow-wave sleep. The main value is not chasing nightly scores, but comparing trends and averages against how you actually feel so you can spot meaningful changes without over-fixating on noisy data.

A meditation app that helps users build a consistent contemplative practice through short guided sessions. It includes brief explanations before meditations about what the practice is doing and what different techniques are meant to cultivate, which can make the sessions easier to understand and stick with. The main value is lowering the barrier to regular meditation while clarifying the purpose and effects of each practice.

Keep social media apps on an old secondary phone instead of your main communication device. This creates a physical barrier and lets you add limits like a timer or shrinking daily allowance, which reduces impulsive checking and makes it easier to control total time spent on social platforms.

Use a hand grip dynamometer or similar grip tool to measure grip strength, often comparing one hand at a time. It’s used as a simple recovery marker because grip tends to drop after hard training, poor sleep, or inadequate recovery, and tracking it can help flag when you’re not fully recovered.

A noninvasive magnetic-coil brain stimulation treatment used to target overactive neural circuits, most often as an adjunct to medication or cognitive behavioral therapy. It’s being explored for obsessive-compulsive symptoms because it may interrupt compulsive motor loops and reduce symptom intensity by modulating circuit activity.

A lockbox that physically prevents access to your phone for a preset stretch of time, often by storing it in another room or using a timed model that cannot be opened early. People use it to create hard friction around compulsive checking, protect deep-work blocks, and break the reflex to reach for social media or notifications.

A sauna practice that uses very hot, traditional dry heat rather than lower-temperature infrared units. The key idea is to get hot enough to meaningfully raise core temperature, which is more likely to trigger sauna-associated adaptations like growth hormone release and heat-shock protein production.

Use properly fitted earplugs in loud environments like concerts or other high-decibel settings to reduce sound exposure and protect hearing. For very loud events, choose plugs with enough attenuation to meaningfully lower the effective volume, since a poor seal can sharply reduce protection. The main benefit is preventing noise-induced hearing damage while still allowing you to participate in the event.
