The Science of Summer Sleep Disruption
How Light, Heat, and Humidity Impact Your Circadian Rhythm—and Simple Ways to Support Rest Naturally
Summer brings golden evenings, barefoot mornings, and a much-needed dose of lightness. But while the season may feel energizing, it also brings subtle disruptions to our sleep—leaving many of us feeling restless at night and groggy come morning.
From late-setting suns to sticky humidity, summer can quietly throw off our circadian rhythm. The good news? With a little intention and the right materials, you can work with the season—not against it—to support more restorative sleep.
Circadian Rhythms & Summer: What’s Really Going On?
Our sleep-wake cycle is governed by our circadian rhythm, a natural, 24-hour clock that’s influenced by environmental cues—especially light, temperature, and humidity.
Here’s how summer can interfere:
-
More daylight hours delay melatonin production, making it harder to feel sleepy at your usual time.
-
Warmer nights interfere with the body’s natural cooling process that signals time for sleep.
-
Higher humidity traps heat and prevents the body from regulating temperature effectively.
These factors create the perfect storm for restless nights, frequent wakeups, and lighter, less restorative sleep.
Why Linen Is a Summer Essential
Nature’s Answer to Hot, Humid Nights
One of the simplest and most effective ways to improve summer sleep? Switching to breathable, natural fibers—specifically, flax linen.
At Sömn Home, we love linen for more than its elegant, lived-in look. This heritage textile is inherently designed to support your body during warm-weather rest.
Here’s what makes linen a summer sleep hero:
-
Temperature-regulating: Linen naturally adjusts with your body’s needs—cool when it’s hot, warm when it’s not.
-
Moisture-wicking: It draws sweat away from the skin and dries quickly, preventing that sticky feeling.
-
Highly breathable: The open weave of linen allows air to circulate freely, keeping you cool all night.
-
Softer with every wash: Forget the stiff stereotype—our pre-washed linen is soft from the start and only gets better.
Sleeping in natural fibers like flax linen helps bridge the gap between environment and body, giving your nervous system the signals it needs to fully relax.
A Simple 3-Step Wind-Down Ritual
Grounding Practices for Deep Summer Sleep
When the body is overstimulated—by heat, light, or a long to-do list—it needs cues to transition into rest. That’s where a gentle, consistent evening ritual can make all the difference.
Try this minimalist 3-step routine:
1. Cool Rinse
Take a warm (not hot) shower 30–60 minutes before bed. This mimics your body’s natural nighttime temperature drop and prepares you for sleep. Bonus: the water can help wash away mental and physical tension.
2. Digital Sunset
An hour before bed, dim the lights and turn off screens. Light a candle, read a few pages of a book, or sip a herbal tea (like chamomile or lemon balm) to help shift from alertness to calm.
3. Linen Layers + Breath
Slip into linen bedding and take a few deep breaths lying down—inhale for four, exhale for six. Let your body register the cooling sensation of the fabric, the weight of the day lifting.
No apps, no gadgets—just you, your breath, and the support of natural materials.
Sleep Seasonally, Sleep Intentionally
As with all things at Sömn Home, we believe sleep should be in harmony with the seasons and the self. Summer doesn’t have to mean restless nights—it simply requires a little awareness and a few intentional shifts.
By understanding how light, heat, and humidity affect your body—and by surrounding yourself with grounding, breathable materials—you can sleep deeply, even under the warmest moon.
