air-pollution
A recent study finds that chronic PM2.5 exposure speeds epigenetic aging by about 15% over five years. We explain why and offer a short self‑experiment.
estrogen
Estrogen acts as a microbial regulator, shifting gut diversity across the cycle; we outline a 10‑day self‑study to track these changes.
stress
Emerging research ties stress‑induced glucocorticoid receptor methylation to metabolic syndrome; we outline a 10‑day self‑study to test this link.
circadian
A recent adolescent study links nighttime blue light to cortisol spikes and higher insulin. We outline a short self‑experiment to see if reducing evening blue light improves metabolic markers.
polyphenols
Recent research links blood‑brain barrier disruption to Alzheimer’s disease. This article explains how curcumin could reinforce barrier integrity and offers a practical 14‑day self‑experiment.
isometric-exercise
A 5‑minute daily wall‑squat can enhance endothelial function and modestly reduce blood pressure in sedentary adults. We explain why, cite recent studies, and give a concrete 8‑week self‑experiment protocol.
gut-microbiome
A new hypothesis links gut‑derived secondary bile acids to hypothalamic TSH receptor expression, offering a 10‑day self‑experiment to test the connection.
vitamin-d
Vitamin D deficiency is associated with dysregulated T-cell responses in several autoimmune conditions. A short self-study can help you gauge its effect on your own immune markers.
exercise
A recent study links morning aerobic exercise to a larger BDNF surge, offering a practical 10‑day protocol for older adults to test neuroplastic benefits themselves.
neuroplasticity
GLP‑1 receptor activation can remodel hypothalamic circuits, improve glymphatic clearance, and lower insulin resistance—here's a 7‑day protocol to test the effect yourself.
nad+
NAD+ fuels SIRT1, which deacetylates PGC‑1α to launch mitochondrial biogenesis. A 10‑day self‑experiment protocol lets you track HRV and metabolic changes.
hrv
Recent studies link Amazon deforestation to air‑quality stress and poetry to HRV gains. Try a 14‑day protocol combining indoor air filtration and daily poetic reading to see how your autonomic balance responds.
