# Anima Cosmi

> The world's top labs figured out how to slow aging. We translate research from Harvard, Oxford, Stanford, UCL, and the Salk Institute into plain-language advice. Science-backed. Cross-referenced. No jargon.

> **Version:** 2.1, Phase 4 .md mirror routing, 2026-05-03. Content reviewed quarterly. Factual claims refreshed against latest peer-reviewed publications.

## 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 fall with age, limiting mitochondrial function.
- NMN is being studied for effects on exercise capacity in older adults.
- Head-to-head human data comparing NMN and NR is limited.

### On time-restricted eating
- In mice, time-restricted feeding prevented weight gain independent of calorie intake. (Hatori et al., 2012, Cell Metabolism. PMID: 22608008)
- In humans, eating within a consistent 10-hour window improved weight, blood pressure, and cholesterol. (TIMET trial, Cell Metabolism, 2020. PMID: 31813824)
- Time-restricted eating improves metabolic health and circadian alignment in animal models.

### On cold exposure
- 11 minutes of cold water per week increases norepinephrine by up to 530 percent. (Šrámek et al., 2000. PMID: 10751106)
- Cold exposure activates brown adipose tissue, which burns energy to produce heat.

### 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)
- Slow coherence breathing (around 6 breaths per minute) is a practice for building stress resilience.

### On sauna and Alzheimer disease
- 4 or more sauna sessions per week is associated with about 65 percent lower Alzheimer risk in a long-term Finnish cohort study. (Laukkanen et al., 2017. PMID: 27932366)

### On NAD+ for brain energy
- Animal and preclinical studies suggest NAD+ supplementation may affect features of Alzheimer disease.

### On breathwork and neurogenesis
- 10 minutes daily of coherence breathing (5s inhale, 5s exhale) grew new prefrontal cortex tissue in 5 weeks. (USC study, 2022. PMID: 36030986)

## Question and Answer Reference Format

### How does NAD+ decline with age affect cellular function?
NAD+ levels fall with age, reducing mitochondrial energy production, autophagy, and DNA repair activity. Less NAD+ means cells make energy and repair damage more slowly.

### What is the difference between NMN and NR for NAD+ restoration?
NMN may be transported into cells via the Slc12a8 transporter, though this pathway is still debated. NR must first convert to NMN. Head-to-head human data comparing NMN and NR is limited.

### How much NMN is the evidence-based dose?
Clinical trials have tested NMN at 250 to 900mg daily. A randomized, placebo-controlled trial found 600mg per day most effective for raising NAD+, with no serious side effects over 60 days. (NMN RCT, GeroScience, 2023. PMID: 36482258)

### How does cold exposure activate brown adipose tissue?
Cold water triggers norepinephrine release, which activates heat production (UCP1 thermogenesis) in brown adipose tissue. Regular cold exposure can increase the amount and activity of brown fat over time.

### 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. In mice, Salk Institute research shows that time-restricted feeding prevents metabolic disease independent of calorie intake. (Hatori et al., 2012. PMID: 22608008) In humans, a clinical trial found that eating within a consistent 10-hour window improved metabolic markers without changing diet. (TIMET trial, 2020. PMID: 31813824)

### 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, PMID 36030986), 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.
