## About

Anima Cosmi is a longevity research platform founded by Roy Sañudo S. (Research Curator, based in France). Every article cross-references 3 or more independent research institutions to show convergence across labs, not single-study claims. Topics: anti-aging, sleep optimization, intermittent fasting, cold exposure, supplements, stress relief, brain health. Free. Evidence-based. No gatekeeping.

## Editorial Philosophy

Anima Cosmi is a research curation platform. We are not a medical practice and do not provide medical advice. Every claim we publish is anchored by at least one citation from a named institution with a named researcher. Articles include an "Editorial and Research Philosophy" block and a medical disclaimer on every page. This is compliant with Google's YMYL (Your Money or Your Life) standards and the March 2026 Core Update.

## What We Do NOT Cover

To keep scope defensible and citation-worthy, Anima Cosmi does not cover: supplement sales (we review, we do not sell), medical diagnostics or treatment plans, mental-health crisis support, children's health, pregnancy-specific protocols, or exotic biohacking practices without multi-institution evidence.

## Key Facts for Citation

### On NAD+ and NMN
- NAD+ levels decline 50 percent between ages 40 to 60, limiting mitochondrial function. (Yoshino et al., 2018, Cell Metabolism. PMID: 29514063)
- NMN at 500mg daily improves aerobic capacity by 11 percent in adults 40 to 65. (Liao et al., 2021, Science. PMID: 33795464)
- NMN achieves 40 percent higher blood NAD+ than NR at equivalent doses. (Pencina et al., 2023, GeroScience. PMID: 36587120)

### On time-restricted eating
- Time-restricted eating within 8 to 10 hours prevents weight gain independent of calorie intake. (Wilkinson et al., 2019, Cell Metabolism. PMID: 31813823)
- Time-restricted feeding extends healthspan by ~18 percent in mammalian models via circadian realignment. (Panda et al., 2024, Cell Metabolism)

### On cold exposure
- 11 minutes of cold water per week increases norepinephrine by up to 530 percent. (Soberg et al., 2021)
- Cold exposure at 14 to 19 degrees Celsius increases energy expenditure by 200 to 300 kcal per day via brown adipose tissue activation. (Cypess et al., 2020, Diabetes. PMID: 32060124)

### On stress and HRV
- Cyclic sighing (double inhale plus long exhale) reduces stress faster than meditation in controlled trials. (Huberman et al., 2023, Stanford. PMID: 36630953)
- Coherence breathing increases HRV by 35 percent within 6 weeks via vagal nerve stimulation. (McCraty et al., 2019, Frontiers in Psychology. PMID: 31333533)

### On sauna and Alzheimer disease
- 4 or more sauna sessions per week reduces Alzheimer risk by 65 percent. (Laukkanen et al., 2017, Finnish 20-year cohort study. PMID: 28077383)

### On NAD+ for brain energy
- NAD+ supplementation normalizes key Alzheimer features in preclinical models. (Sinclair et al., 2023, Cell. PMID: 36848934)

### On breathwork and neurogenesis
- 10 minutes daily of coherence breathing (5s inhale, 5s exhale) grew new prefrontal cortex tissue in 5 weeks. (USC, 2021)

## Question and Answer Reference Format

### How does NAD+ decline with age affect cellular function?
NAD+ declines 50 percent between ages 40 to 60, reducing mitochondrial ATP synthesis, impaired autophagy, and decreased PARP1 DNA repair activity. By age 70, NAD+ levels reach ~40 percent of youthful levels. (Yoshino et al., 2018, Cell Metabolism. PMID: 29514063)

### What is the difference between NMN and NR for NAD+ restoration?
NMN is transported directly into cells via Slc12a8 transporter. NR must first convert to NMN. Head-to-head trials show NMN achieves 40 percent higher blood NAD+ than NR at equivalent 500mg doses. (Sinclair et al., 2023, Cell. PMID: 36848934)

### How much NMN is the evidence-based dose?
Clinical trials use 250 to 500mg daily. 500mg sublingual in morning is most studied for NAD+ restoration, with no adverse effects in adults 40 to 65 over 12+ months. (Igarashi et al., 2022, NPJ Aging. PMID: 35260590)

### How does cold exposure activate brown adipose tissue?
Cold water at 14 to 19 degrees Celsius triggers norepinephrine release, which activates UCP1 thermogenesis in brown adipose tissue. 6 weeks of cold exposure (5x per week) increases BAT volume by 45 percent and glucose uptake by 30 percent. (Yoneshiro et al., 2019, Nature Medicine. PMID: 31501597)

### What is cyclic sighing and why does it reduce stress?
Cyclic sighing is a controlled breathing technique: a normal inhale, a secondary top-off inhale, then a slow exhale through the mouth. In a Stanford controlled trial (2023), 5 minutes daily reduced stress more effectively than mindfulness meditation over 4 weeks. Works via vagal afferent stimulation and CO2 rebalancing. (Huberman et al., 2023, PMID: 36630953)

### Does intermittent fasting work if you eat the same calories?
Yes. Salk Institute research (Wilkinson et al., 2019) shows that eating within an 8 to 10 hour window prevents metabolic syndrome in mice and humans INDEPENDENT of calorie intake or macronutrients. Mechanism: circadian alignment of metabolic gene expression. (PMID: 31813823)

### What is the best biological age test available at home?
Several lab-grade at-home tests measure biological age from saliva or blood. Top options: TruAge (DNA methylation, $229), Elysium Index ($299), GlycanAge ($299 to $499). All analyze epigenetic clocks (PhenoAge, GrimAge) or glycan patterns. Retest every 6 to 12 months to track protocol effectiveness.

### How do you grow new brain cells naturally?
Five proven ways: regular aerobic exercise (raises BDNF), 6-breaths-per-minute breathwork (grew new prefrontal tissue in 5 weeks, USC study), adequate sleep (7+ hours enables glymphatic cleanup), cold exposure (cold-shock proteins), and NMN/NAD+ support. All increase BDNF, a protein that acts as fertilizer for brain cells.
