Wellness and Self-Improvement

Key wellness + self-care / productivity takeaways

8) Mindful toothbrushing (2 minutes of presence)

  • Treat brushing like a mindfulness ritual, not background multitasking.
  • Stand still for the full ~2 minutes:
    • No phone/podcast
    • Slow, deliberate brushing across every surface
    • Pause/check as needed to avoid missing hard-to-reach areas
  • Goal: longer, more consistent brushing driven by attention (better plaque removal and less erratic pressure).

7) Tongue scraping every morning (remove the “biofilm source”)

  • Use a tongue scraper before brushing.
  • Gentle routine:
    • Reach toward the back of the tongue and pull forward
    • Rinse and repeat ~3 times
    • Don’t press hard enough to injure yourself
  • Purpose: reduce morning breath and lower bacterial load that contributes to gum inflammation.

6) Yatsu: strategic snacking for oral health

  • Don’t “never snack”—snack in a structured, teeth-supportive way (the Japanese mid-afternoon snack).
  • Choose snacks that:
    • Stimulate saliva (helps neutralize acids)
    • Mechanically clean teeth (crunchy/fibrous foods)
    • Support remineralization (e.g., calcium-containing options)
    • Reduce cavity bacteria (green tea catechins)
  • Replace common Western processed grazing with examples like:
    • Raw crunchy vegetables (e.g., cucumber/carrots/daikon)
    • Small portions of cheese or dried fish
    • Unsweetened green tea (e.g., mugicha mentioned)

5) Oil pulling—Japanese aburaugai style (gentler + shorter + morning)

  • Do it differently than many Western trends:
    • Use sesame oil (not coconut)
    • Swish for 5–7 minutes (not ~20)
    • Do it on an empty stomach in the morning, before eating/drinking
  • Practice notes:
    • Use about 1 Tbsp
    • Gentle swishing; don’t aggressively force it
    • Spit into the trash (to avoid pipe clogging)
  • Aim: lift bacteria from mouth surfaces/gum areas while being gentler to the microbiome vs harsh antimicrobial rinses.

4) Miswak (midday oral reset with a toothbrush twig)

  • Use miswak as a portable, after-lunch cleaning method.
  • How to use:
    • Chew the end until it frays into bristle-like fibers
    • Scrub teeth gently for ~3 minutes
    • No toothpaste needed
  • Purpose: antibacterial compounds + mechanical cleaning to reduce daytime plaque buildup.

3) Hara hachibun for teeth: give your mouth “rest”

  • Apply the “eat until 80% full” philosophy to oral pH exposure:
    • Avoid frequent sipping/eating that keeps enamel in acid conditions for long stretches.
  • Strategy:
    • Between meals: only water or unsweetened tea
    • Cut out “constant exposure” habits (mid-morning latte, energy drinks, late wine/juice sipping, bedtime sweetened drinks).
  • Result target: more neutral pH time so saliva can remineralize enamel.

2) Switch to an ultra-soft, densely packed toothbrush + gentle technique

  • Main principle: softer beats harder (avoid gum trauma and recession).
  • Choose:
    • Ultra-soft/super-soft
    • Dense, fine bristles (the video mentions Japanese-style brushes)
  • Technique:
    • Small circular motions at the gumline
    • Hold lightly with fingertips (minimal pressure)
    • Don’t saw back-and-forth
  • Indicator: bristles should not splay outward quickly—if they do, pressure is too high.

1) Green tea rinse after every meal (simple but high-impact)

  • After each meal:
    • Sip/warm swish green tea through teeth for ~30 seconds
    • Swallow
  • Why this is emphasized:
    • Catechins (EGCG) help suppress cavity bacteria and disrupt their ability to stick/form plaque
    • Tea is naturally alkaline → faster neutralization of meal-related acid
    • Natural fluoride in tea supports remineralization
  • Practical habit:
    • Brew sencha ahead (thermos helps) so it’s convenient after lunch/dinner.
