Detox in a Toxic World, Part 5: Digital Detox and the New Age of Toxins
Listen to the companion podcast episode on The Trip Lab: #34 – Detox in a Toxic World, Part 5: Digital Detox and the New Age of Toxins
Welcome back to Detox in a Toxic World, a 5-part series exploring environmental toxins, how they affect the body, and what we can realistically do to lower our overall burden in modern life.
In Part 1, we looked at the major categories of environmental toxins, the main ways they affect human biology, and why some people seem much more vulnerable to these exposures than others. In Part 2, we shifted into practical ways to reduce exposures in everyday life, especially in the home, by looking at the home as a health ecosystem. And in Part 3, we moved into the other side of the equation: how the body is already detoxifying and eliminating waste every day, and what we can do to support those natural pathways through nutrition, hydration, movement, sleep, stress reduction, and more. In Part 4, we took an evidenced-based look at detox supplements, protocols, cleanses and all things being sold in the name of detox.
Today we close out the final part to this series by widening the lens beyond environmental chemicals and look at the modern exposures shaping health in less obvious ways. This guide is all about digital detox and the new age of toxins. We dive deeper into how constant stimulation can be toxic, screens, social media, news, poor light environments, circadian disruption and EMFs. We also chat through practical antidotes like nervous system regulation, reducing exposures where it is likely most meaningful and things like grounding and time in nature.
Living in a Toxic World: Nervous System Dysregulation
Modern toxicity is not just chemical. It can also come through constant stimulation, poor sleep, social comparison, chronic news exposure, relational stress, artificial light at the wrong time, and a nervous system that never fully gets to power down. These inputs may not look like toxins in the classic toxicology sense, but they can still shape health through cortisol signaling, autonomic imbalance, circadian disruption, inflammation, and impaired recovery.
Understanding the Problem
Constant digital stimulation impacts our stress physiology. Frequent interruptions, notifications, novelty, and task-switching are associated with higher strain and stress, and faster attention switching has been linked with greater stress load.
Beyond activating the stress response, we also have clear data on how screens and digital stimulation affect sleep. Evening screen exposure is associated with delayed bedtime, shorter sleep duration, and poorer sleep quality. Blue-enriched light at night can suppress melatonin and shift circadian timing.
The impacts are likely due to both blue light and the stimulation technology brings. Phones and social media combine light exposure with novelty, emotion, information, and attention capture right when the body should be winding down. And we actually have data that doomscrolling and problematic social media use are associated with poorer sleep quality, and worse anxiety-related symptoms.
Relationships are health exposures too. Chronic social strain and difficult relationship dynamics are associated with higher inflammation and broader physiologic stress. Toxic relationships are not just emotionally draining; they can also be biologically draining.
Digital Detox
Remove phones from the bedroom at night. Even apart from any EMF discussion (which we will get into below!), this reduces chance of scrolling before bed, waking to check notifications, or starting the day with stimulation instead of regulation.
Consider either scheduling dedicated time for scrolling (only using social media for a defined block once or twice daily) or scheduled time for NOT scrolling (ie no social media before 9am, no news after dinner, etc.).
Turn off nonessential notifications to reduce constant micro-interruptions and helps the nervous system stay out of low-grade vigilance mode.
Try a formal social media detox. Go completely off social media and news for one week to give the brain and nervous system a real break from constant input.
Going deeper, consider a full digital detox weekend or week. So not just off social media, but also off email/phone except when truly necessary. This can be done at a retreat or simply at home with intention.
Use boundaries with relationships and at work. Say no when you need to, operate under delayed response windows when you are able to, have formal do-not-disturb hours, and ultimately just think about if you actually need to be constantly available.
The Antidote: Nervous System Regulation
Beyond just removing inputs, we can actually add in regulatory practices to support nervous system resilience. That way, when stressful inputs arise, our body does not respond as dramatically.
Use practices like breathwork, mindfulness, meditation, yoga nidra and body scans.
App recommendations
Sam Harris; Waking Up - A great mindfulness-based option if you like a more neuroscience-based approach. It offers a new 10 minute mindfulness meditation daily, plus meditation programs and longer-form educational talks.
Open - My personal go-to right now because it offers meditations, soundscapes, yoga nidra and breathwork with a more philosophical tone.
Insight Timer - Likely has the most content, though it often requires more sifting to find the style that best fits for you.
Headspace or Calm - More approachable and user-friendly options for meditation, sleep support and stress reduction.
Exploring Light
Light is one of the most powerful biologic signals the body receives every day. It helps regulate circadian rhythm, melatonin, cortisol timing, alertness, mood, and sleep, which means that the quality, timing, and type of light we are exposed to can either support health or work against it. In modern life, many of us get too little bright natural light during the day and too much artificial, blue-enriched light at night, which is one reason light has become such an important part of the modern detox conversation.
Light Pollution & Understanding Blue Light
Artificial light includes more than just screens. It also includes fluorescent lighting in office spaces, bright overhead LEDs at home, TVs, laptops, tablets, and phones.
Visible light spans roughly 380 to 700 nanometers, and different wavelengths affect the body differently. Shorter wavelengths in the blue range have especially strong circadian effects and suppress melatonin.
Natural light changes throughout the day. Morning and daytime sunlight is brighter and richer in blue wavelengths, while evening light in nature becomes dimmer and warmer. Artificial lighting often does not follow that pattern. And the problem is, we stay indoors under artificial light during the day and then expose ourselves to bright, blue-enriched light at night.
Artificial light at night has effects beyond just sleep. Circadian disruption has been associated with changes in metabolism, mood, cardiovascular health, hormone signaling, and inflammatory pathways. One reason this is taken seriously is that night shift work has been classified by IARC as probably carcinogenic to humans, largely because of circadian disruption.
A Light-Driven Antidote: Circadian Rhythm Alignment
Get morning sunlight first thing in the day when possible. Morning light is one of the strongest signals to the brain that it is daytime and helps anchor circadian rhythm, cortisol timing, and melatonin release later that night.
Use natural light during the day (open windows, sit near natural light, spend more time outside when possible) and dim lights at night (use lamps instead of bright overhead lights in the evening).
Use night mode or lower the brightness at night on phones, tablets, and computers to help reduce short-wavelength light exposure in the evening (but remember that this does not remove the stimulating effects of the device itself).
Consider swapping evening light bulbs to warmer tones. For nighttime use, aim for bulbs around 2200K to 2700K in bedrooms, bathrooms, and living spaces. Save cooler, brighter bulbs like 4000K to 5000K for daytime workspaces if needed.
What about blue-light blocking glasses? The higher-quality evidence so far suggests they probably make little to no difference for eye strain or sleep quality. That being said, the studies were done over relatively short periods of time and controlled for variables. But in real life, if you are trying to shift or support circadian rhythm alignment, that usually takes time, and it is rarely about one tiny intervention in isolation. I think the real question is do they actually block blue light? And it appears that yes, some do. So my takeaway is this: they may still be somewhat helpful as part of a larger circadian-supportive practice, but they are probably not the main intervention. Circadian alignment is about morning sunlight, total screen time, brightness, timing of light exposure, and dimming the home at night… not just one accessory.
Red Light & Near-Infrared Light Treatments
Red light therapy and near-infrared light are part of a field called photobiomodulation. Data suggests that specific wavelengths of light support mitochondrial function, cellular signaling, repair, and recovery. One of the main proposed mechanisms is interaction with cytochrome c oxidase in the mitochondria.
The first thing to know is that red light and near-infrared are not the same thing. Red light is visible light, generally around 630 to 680 nanometers, and has data to support skin and superficial conditions. Near-infrared is invisible and usually in the range of about 800 to 850 nanometers and penetrates more deeply into tissue. The sun emits both.
For red light, the most robust evidence is for skin-related uses. Randomized and controlled studies support red light therapy for skin rejuvenation, collagen support, photoaging, and wound healing. A 2023 study showed improvement in visible signs of skin aging.
For near-infrared light to support mitochondrial function to be used as an ‘antidote’ to blue light (or to treat conditions more broadly), the data is emerging but interesting. Use for the retina is one of the more interesting areas of emerging research. The retina is highly dense in mitochondria, and small human studies using 670 nm red light have shown improvements in color contrast sensitivity, age-related visual decline, inflammation and retinal mitochondrial function. But, therapeutic benefits may extend beyond the retina. Near-infrared penetrates more deeply, and broader photobiomodulation research is exploring possible effects on metabolism, inflammation, pain, neuropathy, wound healing, and hair loss. A 2025 evidence-based consensus concluded that photobiomodulation appears effective for several conditions including peripheral neuropathy, androgenic alopecia, wound ulcers, pressure injuries, diabetic foot ulcer pain, and acute radiation dermatitis.
Here is the key: a device glowing red does not automatically mean it is therapeutic. The important things to look for are actual wavelength and irradiance, not just appearance.
For red-light to be used for skin concerns: Look for wavelengths around 630–660 nm and moderate irradiance, generally around 20–30 mW/cm² at the treatment distance.
For near-infrared for more systemic claims (hair, deeper tissue, muscles, mitochondrial support): Look for wavelengths around 810–850 nm, and usually higher irradiance, often closer to ~100 mW/cm² depending on the distance and target tissue.
Brands to consider (that actually publish wavelength and irradiance data): Mito Red Light, Hooga, PlatinumLED, Joovv
*A common misconception is that you should always block eye exposure. However, the eyes are actually one of the most mitochondria-dense tissues in the body, which is part of why the retinal research is so interesting. That said, you also should not stare directly into very bright LEDs at close range indiscriminately. Follow device instructions and use eye protection if recommended or if the light feels uncomfortable.
Electromagnetic Fields (EMFs)
Electromagnetic fields, or EMFs, are one of the more controversial parts of the modern detox conversation. The reason this topic is so tricky is that the biology is plausible, the data is mixed, and the technology is evolving faster than the research. So rather than dismissing it or panicking about it, I think the most honest approach is to understand what EMFs are, what the major studies do and do not show, and what simple, low-cost precautions may still make sense.
What are EMFs?
EMFs are invisible energy that exist across a broad spectrum and are associated with electrical power and wireless communication. Light itself is on the electromagnetic spectrum. And the truth is, everything has an electromagnetic component. The earth has electromagnetic fields and the human body does too. This is one reason we can measure electrical activity in the body with things like EKGs for the heart and EEGs for the brain. So EMFs are therefore not inherently strange or fringe. That means the true question is what kinds of man-made exposures matter to health… and more importantly at what dose and over what duration.
A side note: If we understand that everything has an electromagnetic component, this is also where some energy-based integrative therapies like Reiki start to feel a little less implausible. And we do have studies showing that one person’s physiologic rhythms and electromagnetic signals can be detectable in another person, even without direct touch.
The main concern in modern life is man-made, non-ionizing radiofrequency EMFs, especially from cell phones, Wi-Fi routers, Bluetooth devices, cordless phones, and other wireless technology. Studies suggest they may impact voltage-gated calcium channels and create oxidative stress in the body. The WHO even describes EMFs as one of the most common and fastest-growing environmental influences in modern life.
Cancer Risk?
In 2011, the International Agency for Research on Cancer (IARC) classified radiofrequency electromagnetic fields as “possibly carcinogenic to humans” (Group 2B). That means there was enough evidence to warrant concern and further research, but not enough to say for sure that RF-EMFs cause cancer in humans. This classification was based largely on limited, but present, evidence around glioma and acoustic neuroma associated with wireless phone use. A follow up case-control study called Interphone found no overall increased risk of glioma or meningioma in general… but did note a possible increased glioma risk in the heaviest users. There was more follow up work that noted an increase in tumors on the same side of the head where the phone was usually held. A 2020 systematic review and meta-analysis found that some of the higher-quality studies suggested a trend toward increased tumor risk with heavier mobile phone use, especially with more cumulative exposure. Then ultimately, a major WHO-commissioned systematic review published in 2024 concluded that RF-EMF exposure from mobile phones showed no overall increase in the risk of the cancers most studied in the human observational literature. The COSMOS cohort paper published in 2024 also found no association between cumulative mobile phone use and risk of glioma, meningioma, or acoustic neuroma. So ultimately, the data is mixed but newer and more robust studies are more reassuring.
At the same time, it is worth noting that some of the older reassuring studies done (that were included in those newer reviews), were actually funded by the phone industry… which does not necessarily dismiss the findings, but something important to point out.
Risk Beyond Cancer?
Studies have also suggested possible relationships between EMF exposure and things like thyroid signaling, oxidative stress, mood and burnout symptoms, cardiovascular regulation, and neurodegenerative risk in at least some populations. These are not proven causal relationships, but they are part of why the field remains open.
One especially interesting, but small, 2023 study looked at 30 healthy young adults that exposed the chest area to frequencies commonly used for Wi-Fi and 4G transmission for five minutes. During exposure, heart rate variability shifted toward more sympathetic activation and less parasympathetic activity, suggesting a temporary move toward a more stressed autonomic state. That does not prove long-term harm, but it does suggest EMFs may have measurable biologic effects even over short periods of time.
There is also data suggesting EMF exposures are linked to changes in brain glucose metabolism (published in JAMA), sleep structure, migraines, and memory changes.
The bottom line: There is emerging evidence that EMFs may impact health in notable ways. Most of the current data notes correlations but not causation and ultimately we need more studies (and this is an active and ongoing field of research). At the same time, exposures to man-made EMFs are increasing each year, so it is reasonable to make small changes now, but not live in fear.
Practical Tips
First and foremost, I don’t think you need to do anything dramatic about reducing EMF exposure just yet (that may change in the future as more data comes out). More importantly, I make this statement because I am thinking about total toxic burden and all of the things we discussed in this whole series that you can do that has more data to support it. That being said, there is plausible data to suggest EMFs may be impacting our health and there are some simple things you can do today to reduce your cumulative exposure. Would I go out an purchase expensive EMF-blocking products? No. But below are some tips that I think are reasonable.
Distance matters. Exposure drops off quickly as devices get farther away from the body. This is one of the simplest, lowest-cost things to keep in mind.
Keep phones out of the bedroom, or at least away from the bed. Even apart from EMFs, this also reduces the risk of late-night scrolling and notification-driven sleep disruption.
Keep the Wi-Fi router away from the bedroom if possible. Again, not because we know it is dangerous, but because this is a simple distance-based precaution.
Use speakerphone when you can instead of holding the phone directly to your head for long calls.
Avoid carrying your phone directly against your body all day if you do not need to.
Do not stand pressed up against the microwave while it is running. They are designed and regulated so that the radiation is meant to satay inside the unit, but there is minimal leakage very close to the surface. *A quick side note on microwaving food: They work by exciting water molecules in food, which creates heat, so they do not make food radioactive. And in some cases, because microwave cooking is faster and uses less water, you could actually make the argument that it may preserve certain nutrients better than longer cooking methods.
Consider grounding (putting your bare feet directly on grass, soil or sand) as a simple practice. The theory is that direct contact with the earth may help discharge electrical charge and support autonomic balance. There is not a lot of evidence to support this yet, but it is so simple and may have other health benefits, which is why I included it here. Aside from EMF protection, we do also have some small studies and reviews suggesting possible benefits on sleep, cortisol rhythm, autonomic balance, pain and inflammation.
The Ultimate Antidote: Nature
For all of the uncertainty, complexity, and overstimulation of modern life, time in nature remains one of the most reliable ways to help the body come back into regulation. The data here is actually much more robust than many people realize. Nature is not just aesthetically pleasing or emotionally calming. It appears to have real effects on stress physiology, cardiovascular health, inflammation, autonomic balance, sleep, and overall resilience. In many ways, nature therapy may be one of the most powerful antidotes we have to the digital, sensory, and lifestyle toxicity of modern life.
A 2018 systematic review and meta-analysis of 143 studies found that greater greenspace exposure was associated with lower salivary cortisol, lower heart rate, lower diastolic blood pressure, lower risk of type 2 diabetes, lower all-cause mortality, and lower cardiovascular mortality. Time in nature may also help lower inflammation. More recent studies suggest that forest exposure may reduce inflammatory markers like CRP, IL-6, fibrinogen, and alpha-1-antitrypsin, giving us a plausible biologic explanation for why nature can feel so regulating to the body.
Forest bathing, or being among trees, specifically, has some especially interesting data. Trees release biologically active compounds into the air called phytoncides, and studies suggest these may help lower cortisol, improve autonomic balance, and support aspects of immune function, including natural killer cell activity.
Overall, I see nature as one of the purest antidotes to not only digital overload and nervous system dysregulation, but also as supportive to the broader themes of detox we have explored in this series. It lowers the volume of the modern environment, reduces sensory and cognitive input, and gives the nervous system a break from constant stimulation and attention capture. Time outside also directly supports the circadian rhythm. As we explored earlier, outdoor light exposure, especially earlier in the day, helps reinforce the body’s natural timing signals and supports better sleep at night.
Final Thoughts
At the heart of this whole series is the idea that health is being shaped by much more than we were taught to look for. Yes, environmental toxins matter. But so do the conditions the body is living in every day: the food, the air, the light, the stress, the relationships, the pace, the information overload, the digital stimulation, and the deeper physiologic terrain that determines how well the body can adapt. Detox, in the truest sense, is not a product or a protocol. It is an ongoing relationship between the body and the world around it.
I also see this series as a sort of antidote to the toxic forces on both sides of modern health. Big Pharma can distort health through profit-driven reductionism, overtreatment, and an overreliance on drugs as the answer to everything. But Big Wellness can be just as distorting in its own way through fearmongering, pseudoscience, overtesting, over-supplementing, and turning wellness into chronic self-surveillance. One side can make us feel like the body is just a machine to medicate. The other can make us feel like the body is so broken and burdened that it constantly needs more products, more protocols, more restriction, and more “fixing.” Neither of those stories is the full truth.
What I hoped to do with this series was offer something different. A way of looking at toxins, detox, and modern health that takes the burden of our environment seriously without collapsing into fear. A way of being curious about emerging science without overclaiming what we know. A way of honoring the intelligence of the body while also being honest about how much modern life asks it to carry. Because I really do believe there are powerful ways to promote health, prevent illness, and support healing that go far beyond just medication. But we have to do that in the right way. We have to stay grounded, scrutinize the data, and be willing to say when something is more hype than help.
So the final thought I want to leave you with is this: your body is not broken, and your health is not something you have to chase through fear. The world may be full of toxic inputs, but the body is also full of intelligence, resilience, and built-in systems working every single day to protect, adapt, and heal. I encourage you to live with more intention, awareness, discernment, and respect for both the body and the environment it lives in.
