Stanford neuroscientist and professor Dr. Andrew Huberman has become a leading voice in the field of longevity, consistently offering scientifically grounded insights into healthy living. Recognized for his expertise in optimizing health and performance, Dr. Huberman frequently shares his own supplement protocols and lifestyle strategies with the public. In a recent podcast episode, he delved into a series of evidence-based health recommendations designed to extend longevity, continuing his mission to make cutting-edge scientific knowledge accessible to a broad audience.
Skin Health: Protecting Against Age-Related Decline
Dr. Huberman opens his discussion by addressing a common concern: the thinning of skin as we age. He emphasizes that sun exposure plays a critical role in accelerating skin aging, unequivocally stating that excessive UV exposure leads to premature skin deterioration. To mitigate this, he advocates for the use of three primary forms of sun protection: physical barriers such as clothing, mineral-based sunscreens containing zinc oxide or titanium dioxide, and avoiding sun exposure during periods of high UV intensity, particularly midday. Dr. Huberman notes that mineral-based sunscreens are preferred over chemical-based options due to concerns over potential endocrine disruption associated with certain chemical ingredients.
Collagen, a crucial protein for maintaining skin elasticity and structure, diminishes with age, leading to thinning and wrinkles. Dr. Huberman highlights moderate evidence suggesting that ingesting collagen proteins, particularly when combined with vitamin C to enhance absorption, can improve skin elasticity and the appearance of smoothness and plumpness. According to Dr. Huberman, the typical dosage ranges from 5 to 30 grams of collagen per day.
In addition to collagen supplementation, Dr. Huberman discusses the benefits of red light therapy. This treatment involves exposure to low wavelengths of red or near-infrared light, which can stimulate collagen production and improve skin texture. Dr. Huberman states that red light therapy, when practiced for 10 to 15 minutes a day, five days a week over several months, can provide moderate improvements in skin appearance. While there is potential for synergistic effects when combining collagen supplements with red light therapy, Dr. Huberman notes that no studies have yet evaluated this combination.
Further strategies for maintaining skin health include the use of retinoids, which improve collagen composition from the inside out, and laser resurfacing, which removes the superficial layer of dead keratinocytes to reduce cancer risk and enhance skin appearance. Dr. Huberman also stresses the importance of a low-inflammatory diet rich in essential fatty acids, particularly from fatty fish, as well as proper hydration and regular use of moisturizers to preserve skin health.

Cold Therapy: An Accessible Intervention for Health Improvement
Cold therapy, another focal point in Dr. Huberman’s recommendations, is presented as a powerful tool for enhancing both mental and physical health. Deliberate cold exposure, such as cold showers, ice baths, or cryotherapy, activates a host of physiological responses, including a significant increase in norepinephrine, a neurotransmitter that improves mood, attention, and alertness. Notably, evidence suggests that cold exposure can also reduce systemic inflammation and improve mental health.
Dr. Huberman suggests that cold exposure should be calibrated to induce discomfort without posing a risk. He recommends staying in cold water for one to three minutes, with water temperatures ranging between 45°F and 60°F. This practice not only offers immediate benefits, such as heightened alertness and improved mood, but also supports long-term health by enhancing metabolic function and increasing resilience to stress. The versatility and accessibility of cold therapy make it a valuable addition to any health regimen focused on longevity.
Sleep: A Pillar of Healthspan
Sleep is another fundamental pillar in Dr. Huberman’s approach to optimizing healthspan. He emphasizes the critical role of rapid eye movement (REM) sleep, a stage of sleep vital for memory consolidation, emotional regulation, and cognitive function. Dr. Huberman advocates for lifestyle modifications that promote improved sleep quality, particularly REM sleep. Morning exercise and cold exposure, he suggests, can help regulate circadian rhythms, thereby enhancing sleep. This recommendation is supported by research, which shows that regular physical activity can enhance overall sleep quality, reduce sleep latency, and improve sleep duration.
In addition to lifestyle interventions, Dr. Huberman introduces non-sleep deep rest (NSDR) protocols, such as Yoga Nidra, as effective methods to achieve cognitive and emotional benefits similar to those provided by sleep. These practices induce deep relaxation and can serve as valuable tools for individuals experiencing sleep disturbances.
Further emphasizing the connection between brain health and longevity, Dr. Huberman highlights research conducted by neuroscientist Dr. Wendy Suzuki at New York University. Dr. Suzuki’s work demonstrates that even brief meditation sessions, as short as 13 minutes per day, can significantly improve working memory, focus, and stress reduction. This zero-cost tool adds another layer to Huberman’s comprehensive framework for optimizing mental health and overall longevity.
Physical Activity: Essential for Cognitive and Physical Well-Being
Physical activity is an indispensable component of Dr. Huberman’s health recommendations, particularly for maintaining cognitive function and preventing age-related cognitive decline. Regular cardiovascular exercise, he notes, is crucial for enhancing neuroplasticity – the brain’s ability to form and reorganize synaptic connections. This process is essential for learning and memory retention.
Additionally, engaging in physical activity shortly after learning new information can enhance the brain’s ability to encode and store those memories more effectively, which Dr. Huberman attributes to the increase in catecholamine (e.g., dopamine and norepinephrine) levels during exercise. Research further supports the notion that consistent physical activity can significantly delay the onset of neurodegenerative diseases, highlighting its importance for cognitive longevity.
Beyond its cognitive benefits, physical activity, particularly intense strength and resistance training, is one of the most effective strategies for preventing cardiovascular disease, the leading cause of death globally. Additionally, high-intensity resistance exercises play a crucial role in preserving muscle mass and bone density, which helps reduce the risk of debilitating conditions such as sarcopenia and osteoporosis.
With this in mind, incorporating physical activity into daily routines is a fundamental aspect of Dr. Huberman’s longevity strategy, as the cognitive and physical benefits of exercise make it essential for optimizing health as we age.
A Devotion to Scientific Rigor and Public Health
Dr. Andrew Huberman’s commitment to advancing public health is evident in his relentless pursuit of translating cutting-edge research into actionable advice. As he puts it, “I’m focusing 98% of my waking life to trying to suss out the best health and science information for you all and get it out to you in formats that are convenient for you, that are useful for you, and that you can apply.”
His ability to distill complex scientific data into practical, accessible guidance empowers people to make informed choices about their health, reinforcing the essential link between rigorous science and everyday well-being. In doing so, Dr. Huberman not only educates his audience but also inspires a broader understanding of how science can profoundly enhance the quality and longevity of life.
