Frequently Asked Questions

Questions, answered

Plain answers about longevity science, our methodology, and how to begin. Every claim here is anchored in the research we cite across the site.

The basics

What is Anima Cosmi?
Anima Cosmi reads the latest health research from Harvard, Oxford, UCL, and Stanford and turns it into advice you can act on. Sleep, fasting, supplements, cold exposure, stress, and more. Free. Science-backed. No jargon.
Can you actually slow down aging?
Yes. Research shows that your biological age (how old your cells are) can be different from your actual age, and you can influence it. Things like eating within a consistent time window, regular exercise, cold exposure, quality sleep, and certain supplements have been shown to slow or even reverse markers of aging in clinical trials.
What supplements help with anti-aging?
The most researched anti-aging supplement right now is NMN, which helps restore a molecule your cells lose as you age. A Harvard professor takes it daily along with resveratrol. Early clinical trials show it can raise NAD+ levels safely. But quality matters: always look for third-party tested products.
Does intermittent fasting really work?
Yes. Research from the Salk Institute showed that eating within an 8 to 10 hour window can prevent weight gain and improve blood sugar, even without changing what you eat. The key is consistency: pick a window that works for your life and stick to it.
Are cold showers actually good for you?
Research says yes. Just 11 minutes of cold water per week boosts mood-related brain chemicals by up to 530%, activates a special fat-burning tissue in your body, and forces your cells to build stronger energy systems. Start with 30 seconds of cold at the end of a warm shower.
What is biohacking?
Biohacking is the practice of using science, technology, and self-experimentation to optimize your body and mind. Common biohacking strategies include intermittent fasting, cold exposure, sleep optimization, and targeted supplements like NMN and resveratrol. The goal is to take control of your biology rather than leaving your health to chance.
How do you start biohacking for longevity?
Start with the basics that research consistently supports: optimize your sleep, try time-restricted eating, add cold exposure, and move daily. These are longevity levers. Harvard, Oxford, and Stanford found the same thing. Track your progress and adjust based on how your body responds.

Longevity science

Is it possible to reverse aging?
Scientists at Harvard have shown that aging is more like a software problem than a hardware problem, meaning parts of it can be reprogrammed. In mice, they have already reversed vision loss caused by aging. In humans, clinical trials have taken years off people's biological age using diet, exercise, and supplements.
What is the best eating schedule for health?
Research from the Salk Institute shows that eating all your meals within 8 to 10 hours and fasting the rest gives your body time to repair itself. Stop eating 3 hours before bed, and try to keep a consistent schedule. This alone can improve blood sugar, weight, and sleep quality.
Why do I feel more tired as I get older?
Your cells produce less energy as you age because they lose a key molecule called NAD+. Levels of it decline as you get older. The good news is that supplements like NMN can help restore it. Better sleep, regular exercise, and fasting also support your body's natural energy production.
What is the fastest way to calm down when stressed?
Stanford researchers found that a double inhale followed by a long exhale is the fastest breathing technique to reduce stress. It works in under 5 minutes. Navy SEALs use a different method called box breathing (4 seconds in, hold, out, hold). Both are free and can be done anywhere.
How long should you take a cold shower?
Research shows that 11 minutes of cold water exposure per week is the minimum for real benefits. Break it into 2 to 4 sessions of 1 to 3 minutes each. Start with just 30 seconds of cold water at the end of your normal shower and build up gradually over a few weeks.
What is the difference between biological age and real age?
Your real age is your birthday age. Your biological age measures how old your cells actually are. Two people born the same year can have very different biological ages depending on how they live. Research from Harvard shows that biological age can be lowered through diet, exercise, sleep, and supplements.
