Modafinil

A prescription drug approved for excessive daytime sleepiness in narcolepsy, shift-work disorder, and sleep apnea — and, in parallel, one of the most popular borrowed-without-a-prescription "focus" drugs. The evidence for genuine cognitive enhancement in healthy, well-rested people is considerably weaker than the internet legend suggests.

Migraine

A chronic neurological disease causing recurring, severe headache attacks — usually one-sided, pulsating, and worsened by physical activity — which can come with nausea, sensitivity to light and sound, and aura. It's not 'just a bad headache' but a distinct disease with its own neurobiological mechanism, affecting more than a billion people worldwide.

CBT-I (Cognitive Behavioral Therapy for Insomnia)

CBT-I is a structured, multi-component treatment program — not a single technique or a list of sleep-hygiene tips — that US and European clinical guidelines recommend as first-line treatment for chronic insomnia, ahead of sleep medication.

Parasomnias: Sleepwalking and Night Terrors

Sleepwalking and night terrors are disorders of arousal from deep NREM sleep, in which the brain is simultaneously part asleep and part awake — the affected person acts, and sometimes screams or walks, with no memory of it the next day.

Narcolepsy

Narcolepsy is a chronic neurological disease in which the brain loses its ability to maintain a stable boundary between sleep and wakefulness — in most patients, the cause is autoimmune loss of the neurons that produce hypocretin. The result is not just severe daytime sleepiness but also sudden intrusions of REM-sleep elements into wakefulness, such as cataplexy.

Sleep and Mental Health

Insomnia isn't just a symptom accompanying depression or anxiety — the largest randomized intervention trial in psychiatric history showed that improving sleep directly reduces paranoia, hallucinations, anxiety, and low mood.

Orthosomnia — Obsession with Sleep-Tracking Data

The harder you try to optimize your sleep based on your watch's data, the worse you might actually sleep — orthosomnia is a documented phenomenon in sleep medicine in which an obsessive pursuit of a 'perfect' tracker score becomes, by itself, a cause of insomnia.

Electroencephalography (EEG)

Electroencephalography (EEG) is a non-invasive test that records the brain's electrical activity using electrodes placed on the scalp. It's the primary tool for diagnosing epilepsy and distinguishing seizures from other causes of loss of consciousness, though a single normal recording never rules out disease on its own.

Derealization and Depersonalization: Symptoms, Causes and What Helps

The feeling that the world is unreal, as if behind glass, or that your own body and thoughts belong to someone else, can be frightening — yet it is surprisingly common. Between a quarter and three quarters of people experience a brief episode of derealization or depersonalization at least once in their lives, while the persistent disorder affects roughly 1% of the population. We explain how to tell a passing episode from a disorder, what triggers it (anxiety, sleep loss, cannabis, trauma), what the research says about treatment and when it is worth seeking help.

Anhedonia (Loss of Pleasure and Motivation): Causes, Link to Depression and What May Help

Anhedonia is the loss of the ability to feel pleasure, or of the drive to do things that used to be enjoyable — hobbies, meeting people, food, sex. It is one of the two core symptoms of depression, but it can also accompany Parkinson’s disease, schizophrenia, chronic stress and sometimes medication, including antidepressants. We explain the difference between not feeling pleasure and lacking motivation, which causes are worth ruling out (sleep, thyroid, drugs), what research says about behavioural activation and when to seek help.

Tics in Adults: Causes, Stress and Tics, and Treatment

Blinking, sniffing, throat clearing or head jerks in an adult can be tics — involuntary, repetitive movements or sounds that worsen under stress. Most often they are a remnant of childhood tics, but a sudden onset in adulthood calls for more careful assessment, because it may mean functional tics, a drug effect or, rarely, a neurological disease. We explain how tics differ from dystonia or muscle twitching, what worsens them in adulthood, which methods have the best evidence (CBIT, drugs) and when to see a neurologist.

Intrusive Thoughts and Obsessive-Compulsive Disorder (OCD): Symptoms and Treatment

Unwanted, recurring thoughts — about contamination, about causing harm, about things contrary to your own values — are experienced by most people and do not in themselves signal illness. We speak of obsessive-compulsive disorder (OCD) only when obsessions and the rituals linked to them consume time and disrupt life. We explain the difference between ordinary intrusive thoughts and OCD, how the cycle of obsessions and compulsions works, what meta-analyses say about ERP therapy and SSRI drugs, and when and how to seek help, without making a diagnosis.

Nocturnal Panic Attacks: Waking Up with Fear and a Racing Heart

Waking suddenly in the middle of the night with a racing heart, breathlessness, a sense of mortal danger and no memory of a bad dream can be a nocturnal panic attack. Between 44 and 71% of people with panic disorder report such episodes, and they occur in sleep without dreams (NREM). We explain how to tell them from nightmares, sleep apnoea, arrhythmia or low blood sugar, what research says about cognitive behavioural therapy and when it is worth checking the heart, thyroid and sleep.

Eyelid Twitching (Eye Twitch): Causes and When to Worry

Eyelid twitching, or eyelid myokymia, is the most common type of facial muscle twitching and in the vast majority of cases it is benign: it comes in waves, lasts from seconds to hours, more rarely a few days or weeks, and goes away by itself. It is more often linked to stress, lack of sleep, caffeine and long hours in front of a screen than to any disease. In this article we separate what is well documented (clinical description, data from an eye clinic) from what is only popular advice, such as magnesium supplements, and show how a harmless twitch differs from blepharospasm and hemifacial spasm and which symptoms call for a doctor's visit.

Light Sensitivity (Photophobia): Causes (Migraine, Dry Eye, Inflammation) and When to See a Doctor

Light sensitivity (photophobia) is an abnormal intolerance of light, not a disease in itself: it most often accompanies migraine, blepharospasm, head injury, dry eye and corneal disease, more rarely inflammation of the uvea, and in some cases it is a sign of an emergency such as meningitis. We explain how light causes pain (retinal-trigeminal pathways), how to distinguish benign from dangerous causes, what studies say about FL-41 tinted lenses and why dark glasses worn around the clock may not be a good idea.

Low Bicarbonate and Anion Gap: What It Means and When to Worry

Low bicarbonate (HCO3, sometimes reported as total CO2) is the simplest sign of metabolic acidosis on a routine electrolyte panel, and the anion gap is a number calculated from sodium, chloride and bicarbonate that helps establish its cause. The same low bicarbonate can mean diabetic ketoacidosis, lactic acidosis, chronic kidney disease, diarrhea or a simple pre-analytical error, and the treatment is different each time. This article explains how to read both parameters, when the gap is raised and when it is normal, what to make of ketogenic and low-carbohydrate diets, and when low bicarbonate is a red flag.

High Eosinophils: Causes (Allergy, Parasites and More)

Raised eosinophils on a blood count (above 0.5 G/L) most often come from allergy, asthma or atopic dermatitis, but can also point to a drug reaction, a parasitic infection, an oesophageal disease, an autoimmune condition or, rarely, a blood disease. We explain the difference between a relative (%) and an absolute (G/L) result, the severity thresholds, the order of tests and the symptoms that call for an urgent consultation.

Pneumatic Leg Compression After Training ("Recovery Boots") — What Does the Research Actually Show?

Pneumatic compression sleeves for the legs, marketed as "recovery boots" or NormaTec, promise faster recovery, less muscle soreness, and better performance in your next workout. The mechanism — sequential compression supporting venous return and lymphatic drainage — is biologically plausible, but actual studies on athletes paint a far more modest and mixed picture than the ads for these devices suggest.

Frequent Nightmares: Causes, Medications and How to Stop Them

Nightmares are not just 'bad dreams': when they return every week they can be a sign of post-traumatic stress, a side effect of medication (including beta-blockers and antidepressants), a rebound after stopping alcohol, or a sleep disorder in their own right. The best-documented treatment is imagery rehearsal therapy, and prazosin — contrary to popular belief — did not beat placebo in a large 2018 US trial.

Melatonin and Alcohol: Can You Combine Them, and What Does Research Say?

Can you take melatonin after alcohol, or together with it? In short: there are no studies confirming that the combination is a good idea, and there is evidence that alcohol itself lowers evening melatonin levels and disrupts sleep structure. Melatonin is not an 'antidote' for worse sleep after drinking, and added sleepiness, fall risk and liver considerations make it wiser not to combine the two.

Armodafinil vs. Modafinil: Does the R-Enantiomer Really Work 'Cleaner and Stronger'?

Armodafinil is sometimes marketed as an 'improved,' purer version of modafinil — stronger, longer-lasting, without the baggage of a second enantiomer. We check what the original pharmacokinetic and clinical studies from both drugs' approval process actually show, and whether the difference is as dramatic as the marketing suggests.

Diuretics and Potassium and Magnesium Deficiency: Why Monitoring Matters

Loop diuretics (furosemide) and thiazide diuretics (hydrochlorothiazide) are a cornerstone of treating high blood pressure and heart failure — effective, inexpensive, and used for decades. Their mechanism of action, increasing sodium excretion in urine, inevitably comes with potassium loss, and in the case of thiazides, magnesium loss too. A large clinical study (SOLVD) found that simply taking a non-potassium-sparing diuretic was associated with higher risk of arrhythmic death in heart failure patients — while potassium-sparing drugs didn't carry that risk. This isn't a reason to avoid diuretics, which save lives, but a strong argument for regular electrolyte monitoring.

Melatonin and Antidepressants (SSRIs): Can They Be Combined?

In general, melatonin and SSRI antidepressants are considered a low-risk combination — one that's sometimes deliberately used clinically when insomnia coexists with depression. There is, however, one specific exception rarely talked about: fluvoxamine, through strong inhibition of the CYP1A2 enzyme, raises melatonin blood levels nearly threefold. This isn't a warning about the entire SSRI class — it's a very specific, well-studied interaction involving one drug.

Jet Lag and Melatonin Dosing: How Much and When to Take It

That melatonin helps with jet lag is by now well-established knowledge — we covered that in our article on the Cochrane review. Far less often discussed is what actually determines effectiveness in practice: not so much the dose itself, but the moment you take it relative to bedtime at your destination, and the direction of travel. We explain a concrete dosing protocol, instead of the generic "take melatonin before bed."

Alcohol Before Bed and Sleep Architecture: What the Research Shows

Alcohol consumed in the evening has a biphasic effect on sleep: in the first half of the night it eases falling asleep and deepens sleep, while in the second half — as the body metabolizes it — it suppresses REM sleep and fragments the night. This is a different topic from our article on alcohol and HRV, which covers autonomic nervous system load; here we focus solely on sleep architecture, meaning what happens to its stages.

NAC and Acetaminophen: Does Supplementation Protect the Liver During Regular Painkiller Use?

N-acetylcysteine (NAC) is the only recognized, life-saving antidote for acetaminophen (paracetamol) poisoning — well-established, well-documented medical knowledge for more than forty years. Far less clear, and often wrongly conflated with that fact, is a completely different question: does daily, prophylactic NAC supplementation protect the liver of someone who simply takes acetaminophen regularly at normal doses for a headache or fever. These are two different questions with two different answers.

Can Stress Cause Both Acne and Erectile Problems at the Same Time?

Breakouts on your face and trouble in the bedroom look like two completely unrelated problems — but for many men they share the same starting point: chronic stress. We explain how cortisol and the stress axis can simultaneously stimulate the sebaceous glands and dampen the erection mechanism, and when you should actually look for a different cause.

Erectile Problems at a Young Age — Where Do They Come From?

Erectile dysfunction is often associated with men in their fifties, yet more and more men in their twenties and thirties report the exact same problem — and feel unusually alone with it. We explain why the causes of ED at a young age are usually different from those in older men, when it's psychological, and when it's worth getting checked out physically.

Why Do You Want Sex, But Have Trouble With Erections?

You clearly want sex, you think about it, your partner turns you on — and yet the erection fails. This combination throws a lot of men off, because it intuitively gets associated with low libido and testosterone. We explain why this specific pattern — desire present, erection absent — usually points in a completely different diagnostic direction.

September 25, 2026

Why Do You Get a Morning Erection, But a Problem Appears During Sex?

In the morning everything works flawlessly, and in the evening, in bed with a partner, the erection weakens or disappears. This is one of the most specific and well-recognized patterns in erectile dysfunction diagnosis — and it almost always leads to the same conclusion. We walk through the clinical logic behind this diagnosis step by step.

Erectile Problems and Stress — a Vicious Cycle That's Hard to Break

Stress makes erections harder, and erectile trouble itself becomes a new source of stress — closing the loop. We break down, step by step, how this mechanism works both physiologically and psychologically, and which concrete strategies actually help break it, rather than just "stress less."

Migraine: Causes, Mechanism, and Treatment — a Full Overview

Migraine isn't just a "bad headache" — it's a distinct neurological disease that, according to current data, affects 14-15% of the global population and is one of the leading causes of pain-related disability worldwide. In this overview we explain how migraine with aura differs from migraine without aura, what's actually known about triggers, how triptans and the new generation of CGRP-inhibiting drugs work, and when a headache warrants urgent evaluation rather than just a painkiller.

Noopept

A nootropic dipeptide with a reputation in the biohacking community as a 'stronger piracetam' — in reality a substance registered as a drug only in Russia and the CIS, with an evidence base built almost entirely on animal and in-vitro studies, and very thin, low-confidence human data.

Phenylpiracetam

A piracetam derivative from the racetam family, registered as a drug only in Russia under the name Phenotropil — and, at the same time, a substance listed on WADA's prohibited list for doping. That second fact, not enthusiastic 'super-nootropic' write-ups, should be the first thing read by any athlete or biohacker considering it.

Methylene Blue

A synthetic dye used in medicine for over 140 years that has found a second life in biohacking as a compound said to support mitochondrial function and cognition — but the same mechanism that makes it interesting is also behind one of the most underappreciated, potentially fatal over-the-counter drug interactions.

PEMF — Pulsed Electromagnetic Field Therapy

Pulsed electromagnetic field therapy is one of the rare cases in biohacking where the exact same technology name hides two completely different stories: a narrow, genuinely FDA-cleared medical use for bone healing, and a much broader, far less supported general wellness promise sold through mats and devices for home use.

Nicotine as a Nootropic

Nicotine outside of cigarettes — gum, lozenges or patches used purely to sharpen focus, with no tobacco combustion — has real, clinically documented effects on attention and processing speed. It's also one of the most two-sided topics in biohacking: the same compound that measurably sharpens attention is also one of the most addictive over-the-counter psychoactive substances available.

Sleep Stages — NREM and REM Architecture

Sleep isn't a uniform state — it's an orderly sequence of physiologically distinct stages, NREM (stages N1, N2, N3) and REM, repeating in roughly 90-120 minute cycles, each serving a different, partly overlapping function in physical restoration, memory consolidation, and emotional processing.

Sleep Hygiene — Principles

Sleep hygiene is a set of behaviors and environmental conditions — from consistent bedtimes to bedroom temperature — believed to support healthy sleep, but contrary to popular belief, the evidence for the effectiveness of individual recommendations, taken alone, is more limited and mixed than usually assumed.

Delayed Sleep Phase Syndrome (DSPS)

DSPS is a circadian rhythm disorder in which the internal biological clock is persistently shifted several hours relative to the socially expected sleep time — a person with the syndrome doesn't have insomnia in the classic sense, just normal-quality sleep occurring at the wrong time.

Bedroom Temperature and Sleep Quality

Before your brain will let you fall asleep, your body temperature has to drop — and if the bedroom is too warm, that signal simply doesn't get through. A bedroom that's too hot or too cold fragments sleep more effectively than many other environmental factors, yet it remains one of the most neglected elements of sleep hygiene.

Polysomnography (Sleep Study)

Polysomnography (PSG) is a comprehensive test that simultaneously records brain activity, eye movements, muscle tone, airflow, respiratory effort, blood oxygen saturation, and heart rhythm throughout a full night's sleep — the gold standard for diagnosing breathing disorders and assessing sleep architecture.

Chronic Stress

Short-term stress is a natural, adaptive body response — the problem is when it becomes chronic. A large meta-analysis of data from nearly 200,000 people found a concrete number for how much chronic job stress raises coronary heart disease risk.

Insomnia

Chronic difficulty falling or staying asleep isn't just a matter of 'sleep hygiene' — the best-studied intervention, recommended as first-line treatment, is cognitive behavioral therapy for insomnia (CBT-I), not sleeping pills.

Cortisol

The main stress hormone — essential for short-term survival, but problematic when chronically elevated.
