Key wellness strategies / self-care & productivity tips

Treat brain fog as a symptom, not “normal you”

  • Brain fog includes:
    • Trouble concentrating
    • Feeling mentally slow
    • Forgetting
    • Losing your train of thought
  • It’s framed as a signal that something in your lifestyle “foundation” is off.

Fix sleep (most common root cause)

  • The glymphatic waste-clearance system mainly clears brain metabolic waste during deep sleep.
  • Poor sleep → waste buildup → worse memory/decision-making/executive function the next day, even after one bad night.
  • Practical sleep protocol:
    • 7–9 hours
    • Same sleep/wake time daily
    • Dark, cold, quiet room
    • No screens for ~1 hour before bed
  • If you’re still exhausted: get a sleep study, especially to check for sleep apnea.

Stabilize blood sugar to prevent crashes

  • The brain relies heavily on glucose (it can’t easily switch to fat).
  • Spikes + crashes from processed carbs can create inconsistent fuel—leading to “brain chasing its tail.”
  • Common pattern described:
    • Carb-heavy breakfast → insulin surge → crash later (the “2:00 p.m. wall”)
    • Late-night carb-heavy meals may worsen next-morning fog
  • Strategy promoted: Primal 60 Challenge
    • Stabilizes blood sugar via food quality, not willpower
    • Protein + fats at every meal to slow digestion and smooth the glucose curve
    • Reported result: afternoon crashes stop “within days” for many participants.

Manage chronic stress to protect brain chemistry

  • Chronic low-grade stress keeps cortisol elevated.
  • This can impair the hippocampus (memory/learning) and disrupt neurotransmitters and sleep—creating a feedback loop with poor sleep.
  • Evidence-backed stress management focus for cognitive function:
    • Exercise, especially aerobic
    • Sleep (ties back to sleep/waste clearance)
    • Social connection (reduce isolation; “phones instead of people”)
    • Parasympathetic activation / recovery time (turn off fight-or-flight)
      • Breathwork
      • Walking without headphones
      • Time in nature
  • Example habit given:
    • 10 minutes daily of silence outdoors, watching nature (used in the Primal 60 program).

Avoid “external masking” that delays recovery

  • Warns against relying on numbing behaviors that suppress brain recovery mechanisms, including:
    • Alcohol
    • Doom scrolling
    • Late-night Netflix binges

Be cautious with supplements; fix the foundation first

  • Some supplements are acknowledged as having evidence (examples mentioned):
    • Omega-3s
    • Magnesium
    • Vitamin D deficiency link to cognitive impairment
  • Core message:
    • If you’re sleeping ~6 hours, eating processed foods, and under chronic stress, supplements won’t fix the problem.
    • Don’t jump to “brain fog stack” products before correcting sleep, diet, and stress.

Order of operations

Prioritize the highest-likelihood causes:

  1. Sleep
  2. Blood sugar / diet quality
  3. Stress recovery (nervous system)
  • Suggested timeline: “Give it a few weeks” and expect meaningful fog reduction.
