The science of sleep: why comfort matters

The science of sleep: why comfort matters

A truly restorative night’s sleep depends on more than just how tired you are—it’s about your environment, bedding, and the way your body maintains temperature and recovers from stress.

Deep sleep and recovery

Deep (slow-wave) sleep is when the body repairs tissues, strengthens immunity, and consolidates memory. Poor bedding—or constant tossing and adjusting—can interrupt this. One study on bedding systems showed that stronger, more supportive configurations decreased cardiovascular stress and improved autonomic balance during sleep (increasing parasympathetic activity).

Temperature regulation

Our bodies naturally drop core temperature before and during sleep. If your bedding traps heat or shifts around, it can disrupt that cooling process, reducing deep sleep and increasing awakenings. Research shows that bedding and sleepwear fabrics influence thermal comfort and thus sleep quality. Another study using a temperature-regulated mattress found that maintaining optimal bed-surface temperature positively altered sleep stages and improved cardiovascular recovery (lower heart rate, better HRV).

Sleep experts often advise keeping ambient bedroom temperatures between about 60 and 67 °F (15–19 °C) for optimal rest, because warmer rooms impair the body's cooling mechanisms at night.

Stress recovery

Sleep is critical for managing stress. After stressful events, sleep helps reset emotional balance and reduce anxiety levels. When your sleep is fragmented or shallow, your body doesn’t fully recover, leaving you more vulnerable to the next day’s stressors.

How cloudfit solves the everyday bedding problem

Cloudfit is designed to stay put—no shifting, bunching, or needing constant re-tucks. That stability is more than convenience: it preserves your thermal microclimate (so you maintain optimal skin and core temperatures), reduces sleep interruptions, and supports deeper, more restorative sleep.

With Cloudfit:

• you don’t waste energy readjusting your comforter at night

• your body’s cooling process is less disturbed

• your bed always looks made (which helps your mind feel calmer)

• the overall sleep environment becomes more consistent, helping stress recovery

All of this means you can get into—and stay in—the restorative phases of sleep that matter most.
