## Quick Answer
Possibly. The evidence is mixed, emerging or context-dependent. There may be a real benefit, but it is usually narrower than the marketing suggests.


## Key Data Point
The stress hormones cortisol and epinephrine trigger the liver to release stored glucose (glycogenolysis) and produce new glucose (gluconeogenesis), a well-established endocrine mechanism sometimes called the 'fight or flight' glucose response.
## What Is It?

This concerns the link between psychological stress and blood glucose, driven by stress hormones like cortisol and adrenaline the body releases during a stress response, rather than a specific product or protocol.


## Why Do People Believe It Works?

It's a mainstay of the broader cortisol-awareness trend on wellness social media, where creators explain the "fight or flight" glucose release as the reason a stressful day or exam can nudge blood sugar or glucose-monitor readings upward.


## What Does the Evidence Say?

Possibly. The evidence is mixed, emerging or context-dependent. There may be a real benefit, but it is usually narrower than the marketing suggests.

Relevant mechanisms: **glucose disposal, insulin sensitivity, meal composition, muscle activity, sleep, stress and medication**.

One biomarker has once again been asked to explain the entire human condition.


## Why It Can Feel Convincing Anyway


### Expectation changes experience

Expectation changes what we notice and how we interpret normal bodily variation — particularly relevant to pain, sleep quality, stress, energy, bloating, mood and recovery. That doesn't make symptoms imaginary; it makes causal interpretation harder.


### Ritual changes behaviour

A new intervention often creates structure: going to bed on time, drinking more water, training consistently, tracking symptoms. Those changes can be useful even when the advertised mechanism is weak.


### Symptoms naturally move around

People tend to try new things when a problem is unusually bad. Many fluctuating symptoms then drift back toward their usual level. The newest product receives the applause; regression to the mean receives no affiliate commission.


### Multiple things change simultaneously

A new-product week can also be the week of better sleep, less alcohol, a changed diet and lower stress. Before declaring victory, ask who else was in the room.


## Safety

Risk depends on the intervention. General red flags include replacing evidence-based treatment, medication interactions, extreme dieting, burns or cold injury, device contraindications, delaying diagnosis, or interpreting serious symptoms as “detox.”
