5 Key Concepts
Adaptogens
Adaptogens are compounds, supplements, drugs, or behaviors that help the body adapt to and buffer stress. They support cellular and organ health, daily functioning, sleep, and performance, though their strict definition is still evolving across communities.
Reactive Oxygen Species (ROS)
These are types of reactions and molecules that occur in cells when they experience stress or age, hindering the function of mitochondria and energy production. Antioxidants are compounds that work to reduce these species.
Inflammatory Cytokines
These are molecules that circulate in high abundance in the body when an individual is under significant psychological or physical stress. Certain adaptogens, such as Lion's Mane and Chaga, are known to help reduce these molecules.
Cortisol
Cortisol is a hormone that ideally peaks early in the day, providing anti-inflammatory, immune-supporting, focus, and mood-supporting effects. Chronically elevated cortisol or a peak that occurs too late in the day is associated with mental and physical health issues.
Physiological Sigh
The physiological sigh is a rapid and effective breathing technique involving two short inhales through the nose followed by a long, complete exhale. This technique is known as the fastest way to buffer stress and calm the nervous system in real-time.
6 Questions Answered
Adaptogens are compounds or behaviors that help buffer stress, and scientific evidence supports their ability to mediate the body's stress response, particularly by reducing cortisol and inflammatory cytokines.
Yes, many adaptogens are found in foods like dark leafy greens and cruciferous vegetables, which contain vitamins and micronutrients that reduce reactive oxygen species and inflammatory cytokines. However, sufficient dosages may require specific preparation or large quantities.
Ashwagandha is a potent adaptogen that dramatically buffers cortisol levels, especially when taken in the afternoon and evening, helping to reduce perceived stress and improve sleep, as shown in human studies.
Adaptogens primarily affect neurotransmitters indirectly by modulating the timing and levels of cortisol, which in turn influences the release of dopamine, norepinephrine, and serotonin, rather than having direct effects.
Effective behavioral adaptogens include viewing morning sunlight, deliberate cold water exposure, mindfulness meditation, specific breathwork practices (like the physiological sigh or box breathing), and non-sleep deep rest (NSDR).
No, it's recommended to cycle off adaptogen supplements like ashwagandha after about 30-45 days for 2-4 weeks, as chronically buffering cortisol is not a good idea for overall health.
13 Actionable Insights
1. Optimize Morning Cortisol Peak
View morning sunlight for 5-30 minutes as soon as possible after waking, without sunglasses, facing the sun’s direction (even on overcast days). This restricts the cortisol peak to early in the day, supporting focus, mood, and an anti-inflammatory effect.
2. Ensure Sufficient Calorie Intake
Ingest sufficient calories for your goals, as calorie restriction can increase cortisol output and lead to a mild mode of stress. This helps avoid unnecessary physiological stress.
3. Consume Dark Leafy Greens
Include at least two to four servings of dark leafy greens and/or cruciferous vegetables per day. These foods contain vitamins and micronutrients that reduce reactive oxygen species and inflammatory cytokines, buffering stress.
4. Use Ashwagandha for Stress
Take two doses of 250-300 milligrams of ashwagandha per day (total 500-600mg) in the early afternoon and evening. This dramatically buffers cortisol, but avoid taking it before exercise and cycle off after 30-45 days for 2-4 weeks.
5. Boost Morning Catecholamines
Engage in a quick 1-3 minute cold shower or ice bath early in the day. This boosts adrenaline, norepinephrine, and dopamine, contributing to an ideal peak of these catecholamines and cortisol.
6. Exercise Early in Day
Exercise early in the day if possible to contribute to the peak of beneficial hormones. If not possible, exercise later, ensuring it does not disrupt nighttime sleep.
7. Practice Daily Stress Reduction
Perform 5-10 minutes of mindfulness meditation, deliberate breathwork (double inhale/full exhale or box breathing), or Non-Sleep Deep Rest (NSDR)/Yoga Nidra in the afternoon. These practices substantially reduce anxiety, stress, and buffer cortisol.
8. Buffer Acute Stress Instantly
When encountering real-time stress, perform one to three physiological sighs (big inhale, second inhale, long exhale). This is the fastest known way to buffer stress and calm down.
9. Consider Lion’s Mane Mushroom
If further stress buffering is needed, consider adding 1,000 milligrams (1 gram) of lion’s mane mushroom per day. It acts as an adaptogen by reducing cortisol and anti-inflammatory cytokines, and if taken daily, cycle off after 30 days or so.
10. Consider Chaga Mushroom
If further stress buffering is needed, consider adding 500 to 1,500 milligrams of chaga mushroom per day. It acts as an adaptogen by reducing cortisol and anti-inflammatory cytokines, and if taken daily, cycle off after 30 days or so.
11. Properly Cook Vegetables
Do not excessively heat dark leafy greens or cruciferous vegetables, as overcooking can destroy beneficial nutrients. If cooking, ingest any colored fluid that leaches out, as it contains adaptogenic molecules.
12. Use Bright Artificial Lights
If morning sunlight is not accessible, use bright artificial lights indoors, such as a SAD lamp, for 5-30 minutes. This serves the same purpose of restricting the cortisol peak to early in the day.
13. Engage in Relaxing Activities
Engage in activities that reduce your stress, such as taking a hot bath, a hot shower, or listening to pleasant music. Anything that reduces stress technically acts as an adaptogen.
5 Key Quotes
The strict definition of adaptogens is still evolving, meaning no one really knows what adaptogens mean and what's included in adaptogens and what's excluded from adaptogens.
Andrew Huberman
The most common definition of an adaptogen is a compound that is typically a supplement or a drug, although it could be a behavior, if you really think about it, that helps you adapt to and buffer stress.
Andrew Huberman
Cortisol peaking early in the day provides an anti-inflammatory, immune-supporting, focus and mood-supporting effect all day long.
Andrew Huberman
Sleep is the foundation of mental health, physical health, and performance.

Zeroing out cortisol is not the goal. The goal is to learn to modulate and control your cortisol.

4 Protocols
Ashwagandha Supplementation for Stress Buffering
Andrew Huberman- Take 250-300 milligrams of ashwagandha in the early afternoon.
- Take another 250-300 milligrams of ashwagandha in the evening.
- Avoid taking ashwagandha prior to exercise to allow for adaptation responses.
- Use for periods of moderate to extreme stress, but not longer than 30-45 days.
- Take at least 2-4 weeks off after a period of use to avoid chronically buffering cortisol.
Daily Cortisol Modulation for Optimal Diurnal Schedule
Andrew Huberman- View morning sunlight for 5-30 minutes as soon as possible after waking, facing the sun without sunglasses, even on overcast days.
- Consider 1-3 minutes of deliberate cold water exposure (e.g., cold shower or ice bath) early in the day to boost adrenaline, norepinephrine, and dopamine.
- Engage in exercise, ideally early in the day if it does not disrupt nighttime sleep, to further promote early cortisol and catecholamine peaks.
Immediate Stress Reduction (Physiological Sigh)
Andrew Huberman- Take a big inhale through the nose until your lungs are full.
- Sneak in a little bit more air with a second short inhale, maximally inflating the lungs.
- Exhale slowly and completely until your lungs are empty.
- Repeat 1-3 times as needed to substantially reduce stress.
Afternoon/Evening Stress Buffering (Behavioral)
Andrew Huberman- Engage in 5-10 minutes of mindfulness meditation, sitting with eyes closed and concentrating on your breathing.
- Alternatively, perform a 5-minute deliberate breathwork practice, such as a double inhale followed by a full exhale, or box breathing (inhale, hold, exhale, hold for equal durations).
- Alternatively, use a 10-minute Non-Sleep Deep Rest (NSDR) or Yoga Nidra protocol, available online.
- Ensure sufficient calorie intake each day, as calorie restriction can increase cortisol output.
