The Problem

Sleep disorder refers to a group of conditions that affect the ability to sleep well on a regular basis, leading to problems with falling asleep, staying asleep, or feeling rested upon waking. It can be caused by a variety of factors such as medical conditions, lifestyle habits, and environmental factors

Cause & Symptoms

Difficulty falling

staying asleep

Repeated instance of waking up earlier than desired

Reluctance around retiring at a sensible hour

In conducting a sleep quality and sleep disorder survey with 178 participants, I gained valuable insights into people's needs and identified specific groups that require assistance.

50% of people choose to exercise or change circadian rhythm when they have trouble falling asleep.

58% of people report waking up in the middle of the night.

60% people admit that they occasionally have difficulty falling asleep, and people report that their sleep quality is fair.

Have you ever experienced
Sleep Disorder?
What are the potential
consequences of sleep disorders?

Sleep disorders like insomnia disrupt cognitive function, emotional stability, and physical health, increasing risks of heart disease, obesity, and weakened immunity. They impair memory, decision-making, and productivity, leading to accidents and reduced well-being. Addressing sleep issues is essential for long-term health and quality of life.

Market Analysis

Why is it different with the product
in the market?

Existing sleep aid products primarily focus on either light therapy or soundscapes, helping users regulate their sleep cycles or mask external noise. However, sleep quality is influenced by multiple senses, not just sight and sound. While light therapy helps regulate circadian rhythms, and white noise can create a calming environment, scent plays a crucial role in relaxation and stress reduction—yet it is often overlooked in current solutions.

Design Goals

Design Decisions
When considering the development of a sleep aid product for middle-aged users like David Thompson, who struggle with insomnia, focusing on noise, light, and aromatherapy can be an effective strategy.

Noise

White Noise or Soothing Soundscapes
Using specific sounds or noise patterns to create a relaxing environment that promotes better sleep.

Light

A treatment for sleep disorders
Uses bright light to regulate the body’s circadian rhythms
Reduced Blue Light Exposure (screen's blue light)

Aroma

Relaxation and Stress Reduction
A popular complementary therapy for sleep disorders

Why Aroma?

Sleep is a deeply sensory experience, yet most sleep aids focus only on light or sound, neglecting the power of scent in relaxation and emotional well-being. Research shows that aromatherapy can calm the nervous system, reduce stress, and enhance sleep quality, making it a crucial yet overlooked element in sleep technology. By integrating adaptive lighting with therapeutic aromas, our design creates a multi-sensory environment that naturally guides the mind and body into deeper, more restorative sleep. This holistic approach supports both physical relaxation and emotional balance, offering a truly restorative bedtime experience.
