Spark

Gratitude journalling gets a mixed reception, and that’s mostly because of how it’s been packaged. The curated Instagram posts, the forced thankfulness, the relentless cheeriness. Strip away the performance and something quieter emerges: a deliberate practice of noticing what’s good, even when things are hard.

MoodFire’s Spark feature is a daily gratitude journal built on clinical evidence, not toxic positivity. Three simple prompts. No pressure to be profound. Just a moment to notice something that went well, someone who showed up, or a small thing that didn’t feel quite as heavy as the rest.

How Spark works

Each day, Spark presents three prompts designed to gently redirect your attention toward things you might otherwise overlook. You respond in your own words. There’s no word count requirement, no scoring, no judgement. Some days it might be a sentence. Other days just a few words.

The prompts rotate to keep the practice fresh and to encourage you to notice different dimensions of your life: relationships, small achievements, moments of calm, things you’re learning.

Why gratitude practice reduces anxiety

The human brain has a well-documented negativity bias: it gives more weight to threats, losses, and bad experiences than to positive ones [1]. This was useful for survival in a dangerous world. It’s less useful when it means your brain spends most of its time cataloguing everything that could go wrong.

Gratitude practice works as a counterweight. It doesn’t eliminate the negativity bias, but it creates a habit of also noticing what’s working. A comprehensive meta-analysis covering 64 randomised clinical trials found that gratitude interventions were associated with reduced anxiety, lower depression, and improved overall wellbeing [2].

Neuroscience research has shown that gratitude practice activates regions of the brain associated with reward processing and social bonding, including the medial prefrontal cortex [3]. Over time, this can shift baseline mood and make positive experiences more salient.

Gratitude during difficult times

One of the strongest findings in gratitude research comes from studies conducted during periods of high stress. A brief gratitude writing study during the COVID-19 pandemic found that it significantly reduced stress and negative affect for participants [4]. Importantly, the benefit came not from ignoring the difficulty but from maintaining awareness of both the hard and the good simultaneously.

This is what separates evidence-based gratitude practice from toxic positivity. You’re not pretending things are fine when they’re not. You’re training your attention to hold a fuller picture.

Expressive writing and emotional processing

The act of writing itself carries therapeutic weight. Pennebaker’s foundational research on expressive writing found that putting experiences and emotions into words reduced intrusive thinking and improved psychological wellbeing [5]. The mechanism appears to involve moving thoughts from circular internal rehearsal to linear external processing.

Spark combines this with the specific focus of gratitude. The result is a daily practice that both externalises your inner experience and gently tilts your attention toward resilience.
