Look at your daily pick-up count.
For most people in the UK, that number sits somewhere between 58 and 150 times a day.
Many people, when they see it for the first time, assume it's a glitch, however it isn't. Every single one of those pick-ups has a biological cost that your brain is quietly paying, and the invoice arrives at night, when you lie awake wondering why you can't switch off and fall asleep.
Your Brain Treats Every Pick-Up As An Emergency
The moment you reach for your phone, something very specific happens neurologically that most people never think about.
Your prefrontal cortex, the region of your brain responsible for focus, planning, decision-making, and executive control has to completely reorient itself. It stops whatever it was doing, assesses the new stimulus on the screen, determines whether it requires a response, and then attempts to return to its previous task.
That entire process takes seconds. It feels effortless and automatic and the majority of the time we aren’t consciously aware of it.
Every single reorientation draws on a finite pool of cognitive resources that your brain has allocated for the day. Neuroscientists refer to this as cognitive switching cost, and research consistently shows that even brief interruptions significantly impair performance on complex tasks, often for far longer than the interruption itself lasted.
Do this 100 times a day and you have spent an enormous proportion of your brain's daily cognitive capacity on nothing more than the act of picking up a rectangle of glass to look at it.
What makes this particularly insidious is what gets left behind. Researchers call it attentional residue. When you switch tasks, even briefly, even voluntarily, a portion of your mental bandwidth remains partially allocated to whatever you just looked at. The email you didn't reply to. The news headline you half-read. The message you saw but didn't respond to. You never fully return to the task you were doing before.
You operate in a state of permanent partial attention. And this partial attention, compounded across an entire day, produces a specific kind of exhaustion. Not the satisfying tiredness that comes from deep focus and genuine effort. The flat, depleted, joyless tiredness of a brain that has been constantly interrupted and never allowed to go deep.
Why Your Brain Treats Notifications Like A Slot Machine
Understanding why this habit is so difficult to break requires understanding something about how your brain's reward system actually works.
Dopamine, the neurotransmitter most people associate with pleasure is not simply a pleasure chemical. This is one of the most important and widely misunderstood facts in popular neuroscience. Dopamine is an anticipation chemical. It fires in response to the possibility of reward, not the reward itself. Its primary evolutionary purpose was to keep our ancestors motivated to seek food, connection, and safety. Whilst making the hunt feel compelling even before the meal was secured.
Modern smartphones have hijacked this system with extraordinary precision.
Notifications are deliberately unpredictable. Sometimes it's something meaningful, a message from someone you care about, news you were waiting for. Sometimes it's nothing, an app update, a promotional email, a reminder you set and forgot about. That unpredictability is not an accident or a design flaw, it is the core mechanism.
Variable reward schedules where the reward is intermittent and unpredictable are the most powerful driver of compulsive, repetitive behaviour that exists in human psychology.
It is the identical mechanism that makes slot machines so difficult to walk away from. The gambling industry discovered this decades ago. The technology industry rediscovered it and applied it to devices that sit in your pocket and buzz against your body throughout every waking hour.
Every time you pick up your phone and find something interesting, the dopamine system is reinforced. Every time you pick it up and find nothing, the anticipation of the next check is reinforced. You cannot lose, from the brain's perspective. Either reward or the anticipation of reward, the cycle is self-sustaining by design.
The Neuroscience Of What's Actually Happening
When you pick up your phone, several neurological processes trigger simultaneously and compound each other in ways that accumulate throughout the day.
The first is the orienting response. The human brain has an ancient, hardwired system for detecting change in the environment. A notification sound, a screen lighting up, even the mere anticipation of one, activates this system involuntarily. This mechanism evolved to keep our ancestors alert to threats and opportunities in their environment, a rustle in the undergrowth, a movement at the edge of vision, it was essential for our survival.
In a modern context, this same system is being triggered by a notification that someone liked your photograph. The brain cannot distinguish between the two as this orienting response fires regardless.
What this means in practice is that your brain is not resting between phone checks. It is running a permanent background scan. A state of continuous low-grade vigilance that keeps your nervous system primed and alert even in moments that should feel calm. You carry the interruption internally, prepared for the next stimulus even when the phone is silent and face down on the table beside you.
The second process is the progressive weakening of sustained attention pathways. The brain operates on a fundamental use-it-or-lose-it principle. Neural pathways that are regularly used are strengthened. Those that fall out of regular use are progressively weakened. Deep, sustained focus, the kind required for complex problem-solving, creative thinking, meaningful conversation, or genuine rest, they all require neural pathways that are becoming less practiced with every generation of smartphone users.
The capacity for boredom is part of this. The ability to sit with stillness, with low stimulation, without immediately reaching for relief, is not just a character trait. It is a cognitive skill that is closely linked to the capacity for deep, sustained thinking and building meaningful connections. The default mode network, the brain's resting state, which is associated with creativity, self-reflection, and the consolidation of experience can only activate when the brain is genuinely unstimulated.
In the modern world we are systematically preventing this from happening.
Five Things Worth Trying This Week
The most effective strategies for reducing your phone's cognitive load are environmental rather than willpower-dependent. Willpower is finite and depletes throughout the day but conscious intentional environmental changes remove the impulsive decisions entirely.
1 — Turn off every non-essential notification without exception. Every notification that arrives, whether you act on it or not, triggers the orienting response and costs attention. Remove the trigger. Remove the cost. Keep notifications on only for direct calls and messages from real people. Everything else can wait, and almost everything else genuinely can.
2 — Batch your phone checks into designated windows. Rather than reacting to your phone throughout the day, decide in advance when you will check it. Three to four scheduled windows, mid-morning, lunch, mid-afternoon, early evening, this is sufficient for almost every professional and personal obligation. The urgency your brain attaches to immediate response is largely manufactured. Very little phone use in daily life is genuinely urgent.
3 — Create physical distance during focused work. Research has demonstrated that the mere presence of a smartphone within visual range, even switched off, even face down, measurably reduces available cognitive capacity. The brain continues to quietly allocate bandwidth to the task of resisting the temptation to check it. Putting the phone in a different room removes this hidden drain entirely, not on silent in your pocket, a different room entirely.
4 — Keep the phone entirely out of the bedroom. Not face down on the bedside table or on the other side of the room. The brain associates the phone with alertness, social connection, and unpredictable reward. Its physical presence in the sleeping environment makes the transition into deep, restorative sleep measurably harder. An alarm clock costs less than £10 and removes the primary justification most people use for keeping their phone beside them at night, not to mention the reduction of EMF.
5 — Practise deliberate boredom Once a day, for a short period, do nothing. Not a meditation. Not a podcast. Not a walk with earphones in. Nothing. Allow your brain to be genuinely unstimulated and notice the discomfort this produces and stay with it rather than reaching for relief. This is not a philosophical exercise or a spiritual task, treat it solely as a cognitive one. The default mode network, the neural system associated with creativity, insight, and the integration of experience can only activate in genuine stillness. You are training a capacity that our modern life is systematically eroding.
The Mineral Your Brain Needs Most — And Why Most People Are Running Low
We have talked at length about what excessive screen use does to the nervous system. The constant scanning and the attention problems, the cortisol that stays elevated long after the phone is put down, the sleep that remains poor and unrestorative.
But there is a deeper question worth sitting with.
Why does the modern nervous system find it so difficult to switch off, even when it genuinely wants to?
Part of the answer is behavioural, the habits and patterns we have explored throughout this article. But part of the answer is biological. And it comes down to a mineral that the majority of UK adults are quietly, chronically short of.
Magnesium.
Magnesium is involved in over 300 biochemical reactions in the human body. But its role in the brain and nervous system is particularly significant, and is particularly under-appreciated in mainstream health conversations.
The brain's primary inhibitory neurotransmitter is GABA, gamma-aminobutyric acid. GABA is essentially the nervous system's off switch. It reduces neural excitability, quiets overactive signalling between neurons, and allows the brain to transition from states of alertness and arousal into rest, calm, and sleep.
Magnesium is what activates GABA receptors.
Without adequate magnesium, GABA cannot do its job effectively. The result is a nervous system that remains in a higher state of excitation than it should, where thoughts race when they should quieten, muscles hold tension when they should release, and sleep remains fragmented and light when it should be deep and restorative.
Magnesium also plays a direct role in regulating cortisol, your body's primary stress hormone. When magnesium levels are sufficient, the stress response is appropriately modulated. When they are depleted, cortisol can remain elevated for longer than it should, keeping the nervous system in a state of low-grade alert that is almost indistinguishable, from the inside, from chronic anxiety.
This is not fringe science. Magnesium's role in regulating nervous system excitability, stress response, and sleep quality is well established in peer-reviewed literature. The relationship between magnesium deficiency and symptoms of anxiety, sleep disruption, brain fog, and mood instability has been the subject of growing research attention, particularly as population-level deficiency has become increasingly recognised as a genuine public health concern.
The Modern Lifestyle Is Actively Depleting Your Magnesium
Here is what makes this particularly relevant to everything we have discussed today.
The same modern lifestyle that drives excessive screen use is the same lifestyle that most aggressively depletes magnesium.
Chronic stress raises cortisol. Elevated cortisol directly accelerates magnesium excretion through the kidneys. The more chronically stressed your nervous system is, the more magnesium you burn through, and the harder it becomes to replenish it to adequate levels through diet alone.
Poor sleep compounds this further. Magnesium levels decline during sleep deprivation, which in turn makes deep sleep more difficult to achieve, a cycle that sustains itself and worsens over time.
Ultra-processed foods, which now account for a significant proportion of many British diets, contain a fraction of the magnesium found in whole, minimally processed foods. Modern intensive farming has progressively depleted the magnesium content of agricultural soil over decades, meaning that even people making genuinely healthy food choices are consuming significantly less magnesium from the same food than previous generations did.
The result is a population that is simultaneously more stressed, more sleep-deprived, more cognitively depleted, and more magnesium-deficient than at any point in recorded history. These are not four separate problems happening to coincide. They are the same problem viewed from different biological angles.
How You Take Magnesium Matters As Much As Whether You Take It
If you have tried magnesium supplements in tablet or capsule form and felt little noticeable difference, there is a specific and well-understood reason for that.
The most common form of magnesium found in standard supplements, magnesium oxide, has a bioavailability rate in the gut of approximately 4%. This means that of every 500mg tablet you swallow, roughly 20mg reaches your bloodstream in a usable form. The remaining 480mg passes through your digestive system largely unused, which is also the reason many people experience bloating, loose stools, or gastrointestinal discomfort from oral magnesium supplementation.
Even higher-quality oral forms face significant barriers. They require a healthy digestive environment, adequate stomach acid production, and an intact gut lining to be effectively absorbed. Stomach acid production naturally declines with age. Under conditions of chronic stress, digestive function is further compromised as the body prioritises its stress response over its digestive processes. For many people — particularly those who are already stressed, sleep-deprived, or over 40, oral magnesium simply cannot deliver the mineral to where it is most needed.
Topical magnesium works through an entirely different mechanism.
When magnesium is applied directly to the skin, it absorbs transdermally, moving through the skin's surface and into the tissues, muscles, and circulation beneath without any digestive processing required. The absorption is entirely independent of gut health, stomach acid levels, age, or stress state. It bypasses every barrier that limits oral supplementation.
For a nervous system that is chronically over-activated, for muscles holding tension that they cannot release, getting magnesium directly to those tissues rather than routing it through a compromised digestive system is not a small distinction. It is a fundamentally different mechanism of delivery. One that reaches the nervous system directly, through the organ, the skin that covers it.
This is why we created our Earthy Topical Magnesium range.
