Clarifications
- Selective Serotonin Reuptake Inhibitors (SSRIs) are a type of medication commonly used to treat OCD. They work by increasing the levels of serotonin in the brain, which helps regulate mood and behavior. SSRIs are considered a first-line treatment for OCD due to their effectiveness in reducing obsessive thoughts and compulsive behaviors. It's important to work closely with a healthcare provider to determine the right dosage and monitor any potential side effects.
- Neuroplasticity is the brain's ability to reorganize itself by forming new neural connections throughout life. In the context of OCD treatment, targeting neuroplasticity with SSRIs can help in rewiring neural pathways associated with obsessive thoughts and compulsive behaviors. This process aims to modify the brain's structure and function to reduce OCD symptoms. By promoting neuroplasticity, treatments can potentially lead to long-lasting improvements in managing OCD.
- Transcranial magnetic stimulation (TMS) is a non-invasive procedure that involves using magnetic fields to stimulate nerve cells in the brain. In the context of OCD treatment, TMS is used to target specific areas of the brain associated with the disorder. By modulating neural activity, TMS aims to alleviate symptoms of OCD by promoting changes in brain function. This technique is considered a promising option for individuals who have not responded well to traditional treatments like medication and therapy.
- The gut-brain axis is a bidirectional communication system connecting the gut and the brain. It involves neural, hormonal, and immunological signaling pathways. This connection plays a crucial role in regulating various physiological functions, including digestion, mood, and even cognitive processes. A healthy gut-brain axis is essential for overall well-being and can impact mental health conditions like anxiety and depression.

Healthy habits
Andrew Huberman delves into how having a healthy lifestyle stems from adopting good sleep routines, engaging in proper exercise, and managing diet—including the optimum intake of omega-3 fatty acids.
Optimizing circadian rhythms
Huberman emphasizes the significance of sleep, particularly its timing within the 24-hour cycle. He explains that the amount of sleep one needs can feel different depending on when that sleep takes place. For example, early risers may feel refreshed with just six hours of sleep, while night owls may feel lousy unless they stay up later. Consistent sleep timing is also a crucial aspect of an effective chronobiology practice.
Adapting rhythm when traveling between time zones
When traveling, it's essential to adapt to new time zones to maintain a typical sleep schedule. Huberman suggests using morning sunlight to shift one’s circadian rhythm and align with local time. He also uses red light in the evenings to lower cortisol levels, aiding in adapting sleep schedules and mitigating jet lag.
To adjust the circadian rhythm when traveling across time zones, such as from San Francisco to New York City, Huberman recommends gradually waking up earlier—by one hour two days before and adjusting further as travel approaches. Knowing your “temperature minimum” is helpful as well; if you normally wake up at 8 a.m., your body hits its temperature minimum around 6 a.m. Exposing yourself to light during this time signals the brain to adjust to an earlier wake-up time.
Alternatively, once in the new destination, using caffeine, engaging in exercise, and adapting to the social rhythm of the city can also help to adjust, although this may result in feeling fatigued late morning unless you can take a brief nap.
To aid military groups and frequent travelers, Huberman consults a chart that factors in the normal wake-up time and desired time shift, suggesting a gradual approach to adapt to the new schedule effectively.
Improving brain function
Using sleep, diet, and exercise
Good quality sleep, with emphasis on slow wave (deep) sleep and rapid eye movement (REM) sleep, is crucial for brain function. REM sleep, especially, is associated with emotional rest and memory consolidation. Huberman points out that maintaining a disciplined exercise routine such as a morning jog can enhance brain function through improved mood, focus, and alertness.
He also advocates for non-sleep deep rest (NSDR) protocols for stress reduction, replenishing dopamine, and enhancing mental and physical vigor, which are essential for overall brain health. Stress management is a critical component in maintaining healthy brain function. He believes ...

- Chronobiology is the study of biological rhythms and how they influence various physiological processes in living organisms. It focuses on understanding the body's internal clock, known as the circadian rhythm, which regulates sleep-wake cycles, hormone production, and other bodily functions. Practicing chronobiology involves aligning daily activities, such as sleep and eating, with the body's natural rhythms to optimize health and well-being. By following principles of chronobiology, individuals can enhance their overall functioning and potentially improve aspects like sleep quality, mood, and cognitive performance.
- A circadian rhythm is a natural, approximately 24-hour cycle that regulates various biological processes in living organisms. These rhythms are influenced by external cues like light and temperature, known as zeitgebers. Circadian rhythms help coordinate essential functions like sleep-wake cycles, hormone release, and metabolism to optimize an individual's overall well-being. They are crucial for maintaining a healthy lifestyle and ensuring proper functioning of the body's internal clock.
- The term "temperature minimum" in the context of circadian rhythms indicates the point in the early morning when the body reaches its lowest temperature. This period is significant for adjusting sleep schedules when traveling across time zones. Exposing oneself to light during this time helps signal the brain to adapt to an earlier wake-up time. Understanding this concept aids in effectively managing jet lag and aligning with a new time zone.
- Non-sleep deep rest (NSDR) protocols are techniques designed to provide rest and relaxation to the body and mind without actual sleep. These protocols aim to reduce stress, replenish neurotransmitters like dopamine, and enhance mental and physical energy. NSDR methods can include activities such as meditation, deep breathing exercises, progressive muscle relaxation, or other mindfulness practices. By incorporating NSDR into one's routine, individuals can promote overall well-being and support healthy brain function.
