Sleepover 10.10
A Collective Pause for Mental Health
Three key takeaways
The Yökyläily 10.10 concept was created for World Mental Health Day as a response to a quietly growing cultural problem: we no longer really “just hang out.” Our everyday lives are filled with performance — productivity, availability, networking, and constant movement — even though research and lived experience show that human connection is one of our most powerful mental resources. The concept reframes togetherness not as something that requires energy or planning, but as something soft, simple, and emotionally necessary.
The idea of a sleepover was chosen because it represents perhaps the purest form of unfiltered togetherness: pyjamas, movies, shared snacks, late-night conversations, and the permission to fully be yourself. On October 10th, people would be encouraged to stay over at a friend’s place or take part in open, organized sleepover-style events for those without close circles nearby. These shared spaces would remove pressure, appearance expectations, and social performance. No dressing up. No schedules. Just being together.
Through Yökyläily, Mieli’s message becomes tangible: you don’t have to fix yourself alone, and you don’t have to perform to deserve connection. The concept transforms mental health awareness from a heavy topic into something human, gentle, and lived in real life. Instead of campaigns built on urgency or fear, Yökyläily 10.10 invites people to slow down together and sometimes, that’s the most radical act of all.
INSIGHT - When Hanging Out Became a Performance
Our key insight was that even though close relationships are one of our most important emotional resources, spontaneous hanging out has quietly disappeared. Free time has turned into performance: networking, productivity, plans: always somewhere, never just being. Yet it’s exactly those ordinary moments with other people that ground us and support our mental health.

BRAND GOAL - From Distant Authority to Playful Companion
Mieli’s brand aspiration was to become more playful, relatable, and easier to approach without losing credibility. We translated this shift into a clear brand personality: warm, human, slightly playful, and emotionally intelligent , a presence that feels like a safe friend rather than a distant institution.

CONCEPT - Sleepover 10.10
For World Mental Health Day on 10.10, we created the Yökyläily (sleepover) concept: a symbolic return to effortless togetherness. The idea was that people would either stay over with friends or join open sleepover-style events to watch movies, wear pyjamas, and simply exist together without pressure. No polishing, no performing, just connection.

Reflection
While the insight behind the concept was strong and emotionally relevant, the final execution remained somewhat flat and didn’t fully translate the idea into concrete, scalable impact.
This project became especially valuable to me on a personal level through teamwork: I found myself navigating and mediating challenging conflicts within the group. It taught me that creative work is never just about ideas. It’s also about communication, empathy, and holding the team together when opinions collide.
