All three gates in the Head Center - gate 64, gate 61, and gate 63 - are physiologically connected to the Pineal Gland, which is located deep near the center of the brain.


The Head Center is a pressure center, which means it's under pressure to understand, think, seek, and figure something out. It constantly pushes us to understand, question, and make sense of life. It's the source of inspiration, doubts, and mysteries and is always trying to move energy toward the Ajna Center, where ideas can take shape and we can eventually bring our genius out into the world!


Undefined Head Center Wisdom

When your Head Center is open or undefined, you're taking in the mental pressure from the people you're around. There's an ongoing attempt to "catch" inspiration from your undefined Head. You're able to feel and sense this mental energy, and this can make you highly sensitive to ideas, questions, and inspiration around you.


With time and awareness, you're here to become wise about the themes of the Head Center. You can potentially become so wise about this center that you can sense which channel or gate others have defined in their Head Center.


Gate 64 (Gate of Confusion) is the pressure to make sense of a constant flow of data that continually recycles through the mind. It wants to resolve Confusion and find clairty. It wants to know what's inspiring about the past.


Gate 61 (Gate of Mystery) is the pressure and inspiration to know inner truth, to unravel mysteries, and to recognize the moment your inner truth pops in.


Gate 63 (Gate of Doubt) is pressure of doubt, asking "Why?", thinking about things with a healthy sense of skepticism for the purpose of seeking logic. It's inspired to know where we're going.

For me personally, gate 63 is the easiest Head Center gate to notice in someone, not only in their words, but I also notice the skepticism in their body language and facial expressions.


The gift of the undefined Head Center is to inspire others. In the not-self, you get lost in mental pressure, doubt, and confusion about things that don’t matter.


The Defined Head Center in Human Design

When you're Head Center is defined, you are broadcasting outwardly the theme of whatever channel(s) and gate(s) you have defined in your design. This means you impact others with the unique theme of your Head definition.


The Pineal Gland, Melatonin, and Circadian Rhythm

The pineal gland in the head produces the hormone melatonin and regulates the circadian rhythm of every biological process in the body that follows a daily pattern, including our sleep-wake cycle. This is an EXTREMELY important function for life, energy balance, and hormonal health!

  • When the pineal gland perceives darkness, it's releases melatonin, which signals to the body it's time to sleep.

  • When the pineal gland perceives light, it decreases melatonin so the body wakes up.

  • This sleep-wake cycle is essential for health, energy, emotional regulation, and metal clarity.


Because the Head Center (with gates 61, 63, and 64) is linked to mental pressure, inspiration, doubt, confusion, and mystery, these energies interact with the pineal gland in important ways:

  • Intense mental pressure (constant thinking, worrying, doubting) can suppress melatonin production.

  • Overstimulation of the Head Center (especially with undefined Head or multiple active head gates) may cause delayed sleep onset or fragmented sleep, because the mind is trying to solve, question, or make sense when it should be quieting down.

  • Gate 61’s impulse for inner truth or mystery can create late-night pondering and wild thoughts that interfere with the ability to fall asleep.

  • Gate 63’s skepticism or doubt can replay questions at night, interfering with deep rest.

  • Gate 64’s confusion while it's processing past experiences can lead to looping thoughts just when the pineal gland is trying to cue rest.


Poor Sleep Impacts Your Pineal Gland, Appetite, Weight, Mood, & More

Sleep quality is deeply anchored in how well the pineal gland, and thus your circadian rhythm, function. Even just one single night of poor sleep will negatively impact every area of well-being, and result in a higher likelihood of weight gain:

  • Poor sleep increases hunger hormones that drive appetite. Research shows if you're sleep deprived you are much more likely to consume more calories compared to days you aren't tired.

  • Poor sleep triggers sugar cravings.

  • Poor sleep impairs how your body metabolizes glucose, potentially creating elevated blood sugar levels and more inflammation.

  • Poor sleep is linked to dysbiosis (an imbalance in the gut microbiome).

  • Poor sleep weakens the immune system, making the body more susceptible to infections and illnesses. If you have an Undefined Spleen, consider your sleep quality to support your immune health.

  • Chronic sleep deprivation is linked to an increased risk of mood disorders like depression and anxiety.

You must fix sleep first and foremost if you want to improve the health of your pineal gland.

The Pineal Gland and Mental Health

There's a two-way relationship between sleep and mental health. Mental health issues (ie: anxiety, stress, mood disorders, emotional overstimulation) can contribute to poor sleep. Poor sleep can in turn negatively impact mental health. On a positive note, good sleep supports healthy brain function and emotional stability.


Anxiety and the "Monkey Mind"

Anxiety and persistent thoughts (the classic "monkey mind") make it difficult to relax and fall asleep and stay asleep. This mental overstimulation interferes with melatonin production, disrupting your circadian rhythm and overall quality of sleep. Without enough melatonin, sleep becomes shallow or fragmented, which in turn feeds more anxiety.


Chronic Stress and Cortisol

Anxiety activates the body's stress response, releasing stress hormones like cortisol. Chronic stress can impact the balance of neurotransmitters and hormones in the brain. If cortisol is high at night, melatonin production drops. This imbalance strains pineal gland function and disrupts restorative sleep. Stress reducing activities, mindfulness practices, meditation, and lifestyle rhythms all positively influence pineal gland health.


Mood Disturbances

Sleep plays a role in emotional regulation. Disrupted sleep patterns can lead to heightened sensitivity or emotional reactivity. Whether your Solar Plexus is defined or undefined, exhaustion heightens emotions or sensitivity to emotions. Personally, I notice I cry more easily when I'm exhausted, which is a sign the nervous system is less capable of tolerating life in general. **Sidenote: the nervous system is biologically connected to the Solar Plexus Center in Human Design.


Screen Time, Blue Light, & Environmental Inputs

Environmental factors like ambient light and blue light from screens affect pineal gland function and sleep quality by suppressing melatonin release, which delays circadian rhythm. Limiting screen time at night, using blue-light filters, reducing light exposure before bed protect sleep quality and pineal gland health.


Nutrition & Lifestyle to Support the Pineal Glands and Head Center Energy

These practices help optimize both your sleep, your pineal gland, and the unique energy of your Head Center gates.


Specific foods or supplements are not guaranteed to directly improve pineal gland health, but certain nutrients and lifestyle practices will support brain health and a healthy sleep-wake cycle. Tt the end of this blog, all recommended supplements are linked at a smokin' price!


1. Tryptophan-Rich Foods

Tryptophan is a precursor to serotonin, which, in turn, contributes to melatonin production. Foods rich in tryptophan include turkey, chicken, nuts, seeds, and dairy products.


2. B-Vitamins or a B-complex Supplement

There are 8 types of B vitamins and they all work together to keep your brain functioning properly.


The B vitamins support healthy energy levels, promote a positive mind, and protect the health of our brain long-term. A deficiency can contribute to impaired cognition. B vitamins are also required for the synthesis of neurotransmitters. Vitamin B6 is specifically involved in the conversion of tryptophan to serotonin. Foods high in vitamin B6 include poultry, fish, potatoes, and bananas.


3. Magnesium

Magnesium is crucial for SO MANY physiological processes, including sleep! It helps the muscles relax, regulates the nervous system to calm the mind, enhances the activity of GABA receptors, is necessary for the conversion of tryptophan to melatonin, and so much more. Foods rich in magnesium include leafy green vegetables, nuts, seeds, very dark chocolate and cacao, and whole grains.


4. Omega-3 Fatty Acids

This is a foundational nutrient for the brain! EPA and DHA, found in fish oil, have a neuroprotective effect, reduce inflammation in the brain, support mental clarity so the Head Center isn't constantly on overdrive. EPA and DHA are also linked to a larger brain size!


Foods rich in omega-3 fatty acids include fatty fish (salmon, mackerel), chia seeds, flaxseeds, and walnuts.


I love this fish oil product by Nordic Naturals. I take 1 Tbsp off the spoon every morning. Here's the scientific reason why I take fish oil or cod liver oil every morning.


5. Antioxidant-Rich Foods

Berries (blueberries, strawberries, blackberries, etc.), turmeric, and colorful vegetables are high in antioxidants which protect the brain from oxidative stress and help pineal function.


6. Sleep Hygiene Practices

Dim the lights in evening. No screens at least 1 hour before bed or use blue-light blockers.

Keep your room dark and cool. Stick to a consistent bedtime/wake time.


7. Relaxation and Mindfulness for Head Gate Energy

  • Gate 64: journaling or expressive arts to process past confusion before bed. Find ways to release the pressure to solve the confusion. Trust that the "ah-ha" will drop in at the correct timing.

  • Gate 61: contemplative meditation, inner truth work -- not at night, but earlier in the evening so the mind doesn’t “pop in” just as you want to sleep.

  • Gate 63: healthy skepticism, but set aside “question time” earlier in the day; trust that not all “why’s” need immediate answers.


8. Manage Stress & Cortisol

To manage stress and cortisol levels, it’s important to incorporate calming, restorative practices into your daily routine. Simple habits like breathwork, gentle walks, spending time in nature, and grounding can help regulate your nervous system and bring your body back into balance.


In the evenings, establish relaxing rituals that help you shift out of sympathetic drive. Activities such as stretching, journaling, or a warm bath can signal to your body that it’s safe to rest and recover.


9. Sleep-Support Supplements

I have had a ton of luck using Quicksilver's Liposomal L-Theanine with GABA before bedtime.

GABA is the body’s main inhibitory neurotransmitter. It supports emotional balance and healthy stress response. L-Theanine is an amino acid that supports relaxation and mood. Together, L-Theanine and GABA help relax the brain for better sleep.


My Real Life Experience with an Open Head Center

I have a completely open Head Center. Sleep quality is something I'm always working on! I require at least 8-9 hours of sleep per night. Artificial light and blue light from screens really interfere with my ability to fall sleep and get into a deep sleep state. I must sleep with the room pitch black -- no ambient light whatsoever. I even bought LED light blocking stickers (like these) for when I travel and stay in an airbnb or hotel, which ALWAYS has lights on electronics. 


When it comes to decision making, if I "live" in my head, I can feel confused, doubt, and overwhelmed by possibilities. Feeling back into my body and following my Sacral Authority has resolved this feeling of living in my head quite easily.

Staying in my body and following my Sacral Authority feels like the medicine for my open Head Center.

When I occasionally use supplemental melatonin, I sleep really soundly. I like to supplement nightly with 1000 mg Taurine and often add in L-Theanine and GABA.


When I settle down for sleep, my "monkey mind" loves to dwell on trivial things that don't matter (the not-self of an undefined Head Center). I've noticed the types of thoughts my mind likes to spin on relate to my Survival View, which makes sense because your mind processes through your View. View is like the filter or orientation your mind naturally sees life through. Questions like "How will I protect myself if someone breaks into my house right now?" or "What's my escape plan from my 2nd floor bedroom if there's a fire?" are at the forefront. What is your View? Do your "monkey mind" thoughts at night relate to your View?


To avoid the monkey mind, I have found reading a book until I fall asleep is an effective and much more peaceful way to fall asleep. Also, as a Manifesting Generator, I always sleep better when I exercise during the day to use up more energy.

Products Mentioned in this Blog


Quicksilver Scientific is the top brand for liposomal products. Liposomal means the nutrition is encapsulated in fat so it can bypass digestion and be transported to where the body needs it. GABA and L-Theanine are very calming. I have had amazing success supporting my sleep using this about 15-30 minutes before going to bed. The flavor is fine. Put a few pumps in your mouth, let it sit there for 30 seconds, and that's it!




Nordic Naturals is very high quality fish oil, and at a reasonable price point. I never burp the taste of fish, even if I exercise after taking it. It tastes like lemon, and if you drink it with water, it goes down easily.










Seeking Health is a very high quality, reputable brand. This provides eight B vitamins with the most bioavailable, active forms of folate, vitamin B12, riboflavin, and B6. The bodily can easily absorb and use these forms.










You can only buy Designs for Health products through a practitioner - me :)

I really like this magnesium powder as a nightcap mocktail. One serving is 300 mg of magnesium in an easy-to-mix powder. The forms of the three types of magnesium are ideal too: Magnesium Orotate, Magnesium Glycerophosphate, and Magnesium Bisglycinate.
