Golden Hour Gains: Your 9-5 Sunlight Blueprint
How To Unlock The Suns Benefits in 3 Easy Steps.
Better sleep. Better skin. Better focus. Better mood. Better metabolism. Better gut health. Better muscle. Better immunity. Better longevity. Better mitochondria. Better everything.
I could go on and on about the sun’s benefits.
It is the source of life for us humans, and it is the greatest lever that we can pull in the pursuit of amazing health.
Unfortunately, it’s harder than ever in today’s modern world.
We stay inside from 9 to 5. We eat lunch indoors. We go inside to work out, and then we come home and it’s night time.
Who knew getting outside was this hard?
As someone who has worked in private equity and at the same time wanted to live a holistic life, I know how hard this is.
But after years of experimenting, scheduling, and researching, I finally cracked the code on how to balance both.
A simple 3-step plan that anyone can do to get more sunlight into your week — without tanning all day or rearranging your life.
Think about what more sunlight could do for you:
How much more energy and focus you would have at work
How much better your sleep would be
How much easier it is to burn fat and build muscle
How much more optimized your entire life would be when you finally align your circadian rhythm with the sun
That’s what you will learn today.
Let’s dive in.
We are utilizing the greatest biohack to exist.
Why We Need The Sun More Than Ever
1. More Energy
Our cells are under attack.
From environmental toxins, endocrine-disrupting chemicals, nutrient deficiencies, and lack of movement, we’re depriving our mitochondria of the ability to create energy.
Low energy equates to low everything.
Sunlight is one of the easiest ways to strengthen your mitochondria.
Specifically, red and near-infrared light penetrate directly into your cells and are absorbed by an enzyme in your mitochondria called cytochrome c oxidase.
When activated by light, this enzyme drives your cells to produce more ATP, reduce oxidative stress, and support cellular repair.
More ATP means every system in your body — mood, metabolism, immune response, focus — runs better.
2. More Aligned Circadian Rhythm
There’s a fancy term in health called Zeitgebers.
It’s a German word meaning “time givers” or environmental cues.
These cues help regulate your circadian rhythm, the 24-hour clock that governs every biological process in the body.
When sunlight hits your eyes in the morning, specialized cells in your retina detect the photons and send a signal to the SCN (suprachiasmatic nucleus) — your brain’s master clock — to activate numerous biological processes throughout the body.
Cortisol and adrenal activation: The SCN signals the hypothalamus to trigger cortisol release from the adrenal glands, which boosts wakefulness, blood sugar regulation, and metabolism.
Digestive readiness: The liver, pancreas, and gut receive time-of-day cues; insulin sensitivity increases, and digestive enzyme secretion aligns with your eating schedule.
Reproductive hormone rhythm: Morning light also helps balance testosterone and estrogen cycles by regulating gonadotropin-releasing hormone (GnRH) from the hypothalamus.
Dopamine activation: Dopamine drives alertness, motivation, and a sense of reward first thing in the morning.
3. Better Mental Health
Depression is on the rise for everyone. That’s why it’s crucial to find ways to increase joy and happiness throughout the day.
Sunlight is one of the easiest, most accessible, and most affordable ways to boost mood and feel good.
How Sunlight Increases Mental Health
Serotonin release: Sunlight triggers serotonin — the neurotransmitter most associated with calm, well-being, and stable mood.
Dopamine activation: Morning sunlight increases dopamine levels, supporting motivation, focus, and a sense of reward. Regular light exposure can help protect against seasonal depression and improve daily drive.
Vitamin D production: UVB rays stimulate vitamin D synthesis in the skin, which supports brain health and helps regulate mood by influencing serotonin and dopamine systems.
Melatonin building: Serotonin is the raw material your pineal gland uses to make melatonin later. More melatonin= better sleep.
4. More Muscle. Less Fat
It’s remarkable that sunlight can not only increase your muscle mass but also influence how fast you burn fat.
Muscle activation: Red and near-infrared wavelengths stimulate mitochondria in muscle cells, enhancing ATP production and improving strength, endurance, and recovery. This acts like energy fertilizer for your tissues — more light equals stronger, faster muscle regeneration.
Fat metabolism: When sunlight hits your skin, specific wavelengths activate lipase, your body’s fat-burning enzyme. Lipase breaks triglycerides into free fatty acids and enter your bloodstream as usable fuel.
Circadian synergy: Morning sunlight strengthens your circadian rhythm, aligning hormonal peaks in cortisol, testosterone, and growth hormone with daytime activity. This timing enhances muscle repair, metabolic efficiency, and workout performance when your body is most primed to use light-driven energy.
5. Better Gut Health And Immune Health
It’s incredible to think that sunlight not only produces vitamin D — essential for the immune system — but also directly impacts gut health.
Since about 70% of the immune system resides in the gut, this connection is powerful.
Gut microbiome diversification: Research found that UVB exposure on the skin increases gut microbiome diversity, including populations of bacteria linked to lower rates of IBD and autoimmune disease.
T cell calibration: UVB light modulates both innate and adaptive immune cells — those responsible for distinguishing threats from normal tissue. This helps explain why sun deficiency is strongly linked to autoimmune conditions.
Now you know why sunlight transforms "better everything" — but knowledge alone won’t rewire your biology.
The real power comes from doing it daily. Here’s your simple 3-step protocol to make it automatic...
How to Unlock the Sun’s Benefits: 3-Step Protocol
Step 1 — Morning (Wake + SCN Reset)
How to do it:
Get outside for at least 5-10 minutes within 30-60 minutes of waking. No sunglasses. No windows.
Take your morning coffee or water outside and watch the sun rise.
Do 5-10 minutes of stretching and mobility while you lay in the grass.
Write down 5-10 things you are grateful for in a journal.
Do an energizing breathwork routine. Sun+breath= Biostack.
Personally, I step out onto my balcony and do my morning mobility and foam rolling watching the sun rise over the Dallas. I also like doing some lymphatic shaking, deep squats and breathwork all in the morning light. It sets the entire tone of my day in a way nothing else does.
Step 2 — Midday (Muscle + Metabolism Fuel)
How to do it:
Get 10-20 minutes around noon-2pm. Expose as much skin as possible.
Eat lunch outside (parking lot, balcony, park bench).
Take all phone and zoom calls (when possible) outside
Walk barefoot or do bodyweight squats/pushups in direct light.
Take a 15-minute walk outside after eating; this also blunts the post-meal glucose spike
If you work from home, set a phone alarm labeled “go outside” at noon
When I work from home, I love lying on my balcony at midday and doing a short breathwork session. It lets me decompress from the intense morning work session, get my vitamin D window in, and come back to the afternoon actually ready to focus.
Step 3 — Sunset (Wind-Down + Repair)
How to do it:
Get 15-30 minutes at sunset. Eyes on orange/red horizon. No screens.
Sip herbal tea outside or do gentle yoga/walking as sun dips.
Practice 4-7-8 breathing while watching colors change.
Journal 3 wins from your day (doubles Step 1 dopamine).
Bring a family member, partner, or friend — sunset walks are one of the best low-effort relationship habits.
Stack it with something you want to do less of screens: audiobooks, podcasts, or just silence
After work I love either playing tennis, walking the trail near our home with my girlfriend, or even just walking to Whole Foods to pick up groceries for my afternoon sunlight. Then once I get home I watch the sunset while cooking dinner. A fabulous biohacked meal!
5 Important Sunlight Considerations.
1. Can I get all of the benefits of the sun with my clothes on?
Not all benefits, but you'll still achieve amazing results just getting outside.
Clothing filters out most UV light, significantly reducing vitamin D production when covered up.
Near-infrared light can still reach skin through light fabrics.
For full benefits — especially vitamin D and metabolic effects — expose arms and legs when possible.
2. Can I “front-load” sun exposure on weekends to make up for the week?
Weekend beach days do wonders, but daily exposure matters most.
Your circadian clock needs consistent morning signals to stay calibrated.
Even 5-10 minutes on busy weekdays keeps momentum going
3. How long do I actually need to be outside to see benefits?
Sun benefits kick in faster than a YouTube video.
10-20 minutes midday sun on exposed skin = meaningful vitamin D.
5-10 minutes morning light = circadian/serotonin boost.
Consistency beats duration — no hours required.
4. How much morning sunlight do I need to shift my circadian rhythm?
5-10 minutes works for general wellness and mood.
I notice sharper focus at 20+ minutes.
Research minimum: 5-10 minutes bright light within 30-60 min of waking (clear days).
Overcast days: aim 20-30 minutes.
5. Does sunscreen block the benefits?
Significantly — blocks vitamin D and most metabolic effects.
Commercial sunscreens contain endocrine-disrupting chemicals like oxybenzone, octinoxate that absorb into bloodstream.
