Anxiety is not a factory defect. It is a biological surveillance system that has kept us alive for hundreds of thousands of years. When we perceive a threat, the body prepares: heart rate rises, blood flow is diverted to the muscles, the senses sharpen. That state is useful in small doses: it prepares us, motivates us, focuses us. The Yerkes-Dodson curve describes this reality well: a certain level of arousal improves performance. The problem appears when that alarm system stays switched on, when vigilance becomes hypersensitive and starts to interpret any stimulus, or even its absence, as a threat. That is no longer adaptive anxiety, it is pathological anxiety: it does not drive you to act, it paralyzes; it does not prepare, it exhausts.
In clinical practice there is no single "anxiety." There are distinct manifestations that share a common root but call for different approaches. Simplifying what the DSM-5 treats as separate categories, we can recognize six faces that most people identify in their own experience. Generalized anxiety is a constant rain of worries: the mind looks for problems to solve, even invents them, and does not rest. Panic disorder is the sudden explosion: attacks of intense fear that peak within minutes, with palpitations, chest tightness, a feeling of suffocation, and, above all, the terrifying conviction that you are going to die, go crazy, or lose control. Social anxiety is the extreme fear of being observed, judged, or negatively evaluated in interpersonal situations. Specific phobias concentrate fear on a particular object or situation. Post-traumatic stress replays the past in the present. And finally, somatic anxiety, which disguises itself as diffuse physical symptoms: chest tightness, abdominal pain, dizziness, tremor. Recognizing which type predominates is not a clinical label but a compass for choosing an intervention.
From a neurobiological perspective, pathological anxiety involves hyperactivation of the amygdala, the brain's fear center, and dysregulation of the prefrontal cortex, which under normal conditions interprets the stimulus and exerts executive control. When that circuit is altered, the amygdala sends danger signals that the cortex can no longer switch off. Several neurotransmitters are involved, and their dysregulation explains why effective interventions are also varied.
GABA is the nervous system's main brake. When its tone drops, neuronal excitability rises. Anxiolytics such as benzodiazepines and kava act here, and so do most natural anxiolytic interventions (Silexan, apigenin, valerian, L-theanine). Serotonin modulates mood, sleep, and emotional regulation. In chronic stress its synthesis and release decrease; SSRIs and 5-HTP are the interventions that act on this pathway. Norepinephrine participates in the "fight or flight" response; its hyperactivation explains the hypervigilance, tachycardia, and insomnia of severe anxiety. Beta-blockers are the classic pharmacological example. Glutamate is the main excitatory neurotransmitter; its excess maintains sensitization of the fear circuit, which is why NAC (a glutamatergic modulator) shows a signal in OCD and refractory anxiety.
Reducing chronic anxiety to "a serotonin imbalance" is an oversimplification that science has been moving past for decades. There are at least four more layers worth keeping in mind.
The HPA axis (hypothalamic-pituitary-adrenal) regulates the stress response through cortisol. In health, cortisol has a morning peak that activates us and declines throughout the day. In chronic stress that rhythm flattens: morning cortisol drops, nighttime cortisol rises, and the body shifts into a state of "permanently switched on" that depletes reserves and precedes burnout. Adaptogens such as ashwagandha and rhodiola have their role here, along with sleep hygiene, morning light exposure, and slow breathing.
The gut-brain axis connects the microbiota with the central nervous system via the vagus nerve, bacterial metabolites, and immune modulation. Gut dysbiosis generates low-grade inflammation that crosses the blood-brain barrier and aggravates anxious and depressive symptoms. It is the biological basis for why psychobiotics (B. longum 1714, L. rhamnosus JB-1) are an active field of research, although translation to humans remains modest.
Chronic systemic inflammation —measured by markers such as high-sensitivity CRP, IL-6, TNF-α— correlates with anxiety severity in multiple cohorts. Omega-3 EPA, curcumin, and the Mediterranean diet are interventions with consistent anti-inflammatory and anxiolytic signals.
Mitochondrial dysfunction, the burden of xenobiotics (microplastics, heavy metals, pesticides), and nutritional deficits (B12, magnesium, vitamin D) complete the list of "hidden biological causes" that the traditional psychotherapeutic approach sometimes overlooks and that in practice change the prognosis when they are identified and corrected.
Anxiety is approached with a ladder of interventions that can be stacked according to severity and preference. The first layer is neither pharmacological nor supplement-based: regular sleep, morning sunlight, regular aerobic physical activity, gradual exposure to what is feared, and slow resonance breathing (5.5 breaths per minute). None of it is glamorous; all of it has solid evidence and is the foundation on which the rest rests.
The second layer is the supplements with the best clinical evidence in their category. For generalized anxiety, Silexan (oral lavender oil) with efficacy comparable to paroxetine (PMID 36717399) and chamomile (Amsterdam 2009, PMID 19593179) have the best RCTs. For panic, high-dose inositol (12-18 g/day, PMID 11386498) has a promising crossover trial. For the HPA axis, ashwagandha is the adaptogen with the most evidence (PMID 31728244) and rhodiola the best documented in burnout (PMID 28219059). As useful and very safe adjuncts: magnesium glycinate, L-theanine, glycine, and apigenin.
The third layer is structured psychotherapy: cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), IFS (Internal Family Systems) for work with internal parts, EMDR when there is trauma. Without this work, the ceiling for improvement is low.
The fourth layer is classic pharmacotherapy: SSRIs/SNRIs for moderate-to-severe disorders, benzodiazepines only occasionally and with medical judgment. The question is not "natural vs. chemical" but "what combination works for this person at this moment."
Anxiety becomes a disorder when it interferes with daily life, lasts more than six months, or causes significant distress. Clear signs: recurrent panic attacks, avoidance of situations you did not previously avoid, insomnia lasting more than two weeks, thoughts of harm, use of alcohol or screens as self-medication. Nothing written here replaces the evaluation of a qualified professional. This text is a map to orient you, not a treatment.
