Anxiety – What It Is, Why It Happens, and How to Deal With It

When you hear the word Anxiety, a feeling of worry, nervousness, or unease about an uncertain outcome. Also known as anxiousness, it shows up in the body as a racing heart, shaky thoughts, or restless nights. Anxiety isn’t just “being nervous” – it can ripple through daily decisions, work performance, and relationships.

One major player that often shows up when anxiety flares is medication, prescribed drugs that target chemical imbalances or physical symptoms. Antidepressants, anti‑anxiety pills, and even some antipsychotics are used to calm the storm. Yet each drug brings its own side‑effect profile, and some people report increased jitteriness or sleep disruption. Understanding how a medication works and what trade‑offs it brings can make the difference between relief and a new set of worries.

Stress, Sleep, and the Anxiety Cycle

Another key piece in the puzzle is stress, the body’s response to perceived threats or overload. Chronic stress spikes cortisol, which can heighten the brain’s alarm system and keep anxiety on constant high alert. When stress piles up, it’s harder to unwind, and that leads directly to poor sleep, the restorative cycles that reset mood and cognition. Lack of REM sleep, in particular, reduces the brain’s ability to process emotions, making worries feel louder the next day. So the relationship reads like a chain: stress fuels anxiety, anxiety blocks good sleep, and bad sleep fuels more stress.

What does this mean for you? First, recognize that anxiety often has three overlapping drivers: the mental chatter (stress), the chemical environment (medication), and the body’s recovery mode (sleep). Tackling any one of these can soften the whole loop. Simple actions like a short breathing exercise before bed, a consistent sleep schedule, or a quick chat with your doctor about dose timing can have outsized effects.

Beyond lifestyle tweaks, many readers find value in learning how anxiety shows up in specific health contexts. For example, certain cancer drugs such as lenalidomide can trigger hormonal shifts that elevate worry levels. Antifungal treatments like griseofulvin sometimes cause skin irritation that adds to discomfort and stress. Even chronic conditions like Addison’s disease, where cortisol is low, can leave you feeling unusually anxious. These real‑world links illustrate why a one‑size‑fits‑all approach rarely works.
