Hand washing
Still the single most effective infection-control habit ever measured. Soap and 20 seconds of warm water before eating, after the bathroom, after public transit, and after handling raw meat. Hand sanitizer (60%+ alcohol) is a backup, not a replacement.
Oral care
Your mouth is connected to the rest of your body in ways the public health messaging is finally catching up to. Periodontal disease is associated with cardiovascular disease, diabetes, and adverse pregnancy outcomes.
- Brush twice a day with a soft-bristle electric brush; 2 minutes minimum.
- Floss once a day. A toothbrush cannot reach the surfaces between teeth where most cavities and gum disease begin.
- Use a fluoride toothpaste — the single best-supported topical preventive in dentistry.
- Tongue scrape in the morning. Cheap, fast, dramatically reduces bad breath.
- See a dentist every 6 months for cleaning and screening.
Body and scalp
- Daily shower isn't always necessary; rinse the high-bacteria zones (groin, armpits, feet) every day.
- Use a gentle, fragrance-free cleanser. The body's microbiome doesn't need to be scrubbed off.
- Moisturize within 3 minutes of toweling off — the skin barrier matters for everything from eczema to infection risk.
- Shampoo as often as your scalp needs — daily for some, twice a week for others. Conditioner length-only.
Nails & feet
Trim straight across to prevent ingrowns. Dry between the toes. Don't share clippers. Athlete's foot is preventable and very treatable; ignore it and it spreads.
Home cleanliness
- Sheets and pillowcases: wash weekly in hot water.
- Towels: wash every 3–4 uses; dry fully between uses.
- Toothbrush: replace every 3 months or after illness.
- Kitchen sponge: microwave damp for 1 minute daily, replace weekly.
- Phone screen: wipe down with a microfiber cloth and a screen-safe alcohol wipe a few times a week.
- Door handles, light switches, faucet handles: wipe down weekly.
Laundry
Workout clothes get rinsed or washed after every session. Hot water for sheets, towels, and underwear; cold for everything else (saves energy and color). Skip fabric softener — it coats fibers and many fragrances are skin irritants.
