Behaviors

For unskilled lifters, favor more supported machine-based movements to reduce injury risk while fully contracting target muscles; avoid starting with unsupported or less stable options such as front-loaded goblet squats or cable exercises if instability is a concern.

Avoid box jumps for untrained individuals because of higher injury risk from plyometric loading.

Improve strength and hypertrophy to also improve VO2 max and cardiometabolic markers.

Avoid higher-dose or frequent ibuprofen/NSAID use because it may impair muscle hypertrophy or strength and can harm the gastric lining.

Wash skin in ways that support rather than diminish the skin microbiome; avoid disruptive substances. For acne and general skin care, cleanse regularly but not excessively, typically 2 to 3 times per day, using a gentle, unscented, unfragranced cleanser; use lukewarm rather than hot water. Before applying acne treatments, clean skin first with mild zero-fragrance soap and lukewarm water.

Look up the UV index rather than relying on subjective feel to decide when to be extra cautious with sun protection.

Especially avoid chemical sunscreens in children younger than 6 months. For adults, prefer mineral sunscreens or physical barriers if concerned about endocrine-disrupting chemicals such as oxybenzone or avobenzone. If only chemical sunscreen is available on a high-UV day, use it only if necessary and sparingly, perhaps on sensitive areas like the face, ears, or neck rather than every day.

If a pimple-like lesion, spot, or seeping area persists for a month or more, get it checked by a dermatologist without waiting longer.

Too much copper can induce inflammation; do not supplement excessively beyond normal dietary or multivitamin amounts.

Avoid tretinoin, Retin-A, and related retinoid products if pregnant, breastfeeding, or planning pregnancy due to serious fetal developmental risks.

Use red light plus near-infrared phototherapy consistently for skin quality, acne symptoms, wound healing, psoriasis symptoms, and youthful appearance; effects are generally mild to moderate.

Do not supplement vitamin A excessively because overdose risk is high with this fat-soluble vitamin.

For acne concerns, especially post-puberty or with suspected hormonal issues, check androgen levels over time in both males and females.

Avoid overeating to prevent large spikes in insulin and blood glucose that can worsen acne; also avoid excess sugar.

If acne is a problem, try removing dairy entirely for a period and see whether skin improves.

For a major event and a severe visible pimple, a dermatologist may inject a corticosteroid to reduce redness more potently.

After gym sessions, shower or bathe as soon as possible and wash the face with a gentle cleanser because of sweat and bacteria exposure.

Recommended from a harm-reduction perspective because concentrates can reach 90–98% THC, are hard to titrate, produce much higher blood THC levels, and are more associated with tolerance and adverse responses.

Explicit warning not to expose dogs to cannabis.

Recommended because many THC products look like gummies or candies; improper storage can lead to accidental pediatric ingestion and severe intoxication.

If a child is acting strange and may have ingested THC-containing products, seek emergency care immediately despite possible legal consequences.

Edible onset is described as a minimum of 30–45 minutes and can take up to 90 minutes for some people. Redosing before that window increases risk of overconsumption and is a common cause of adverse events with edibles.

General harm-reduction recommendation to proceed cautiously and avoid ingesting too much too quickly, especially relevant for edibles and inexperienced users.

Suggested as a harm-reduction strategy because oral routes bypass combustion-related lung damage, and vaporizing plant matter avoids combustion byproducts such as carbon monoxide and may reduce lung-related harms compared with smoking. Oral use, however, comes with dosing and timing issues.

Recommended as a precaution because cannabis can cause vasodilation, postural hypotension, and compensatory tachycardia, which may unmask vulnerabilities or contribute to cardiac events or strokes.

Discussed as something that seems to relieve cyclic vomiting syndrome associated with heavy cannabis use; mechanism unclear but repeatedly noted.

Use your body type and structural tendencies as a guide; avoid pushing into extreme activities that mismatch your anatomy, especially at high levels.

Apply enough stress for adaptation, but do not cross the threshold where cumulative trauma begins.

Purposefully provoke pain to identify the mechanical cause; if pain cannot be provoked mechanically, that suggests a non-mechanical component.

If a specific exercise or movement reproduces pain, avoid it temporarily rather than repeatedly provoking symptoms.
