Episode notes
Nicotine's Neuroprotective Signal
- Nicotine may protect neurons and show evidence of reduced Parkinson's and Alzheimer's risk in some studies.
- This is not a recommendation to start nicotine because blood pressure effects and habit risk remain significant.
Optimize Deep Sleep Then REM
- To maximize REM, sleep long enough and consider warming the bedroom toward morning to increase REM duration.
- Capture deep slow‑wave sleep by keeping a regular bedtime and avoiding late caffeine to get restorative early-night sleep.
Ask About Low‑Dose Tadalafil
- Men over 40 should consult their doctor about low‑dose tadalafil (2.5–5 mg nightly) to dilate capillaries and lower blood pressure.
- This may offset nicotine or vasoconstrictive effects but requires prescription and medical oversight.
