Staying Cool During Hot Summer Nights: Bedding & Lifestyle Tips for Better Sleep

 Hot summer nights can disrupt your sleep and leave you feeling groggy the next day. Whether it’s humid air, trapped body heat, or bedding that doesn’t breathe, the result is the same: tossing, turning, and waking up in a sweat.

Fortunately, with the right sleep environment and a few smart nighttime habits, you can sleep comfortably—even during heat waves.

Here’s how to stay cool and sleep better all summer long.

Upgrade Your Bedding to Sleep Cooler

The foundation of cooler sleep starts with your sheets and comforter. Many traditional materials, like cotton or polyester blends, can trap heat and moisture.

Instead, opt for breathable, moisture-wicking fabrics.

Look for:

• Eucalyptus sheets made with TENCEL™ lyocell, like the  AiryWeight Cooling Eucalyptus Sheet Set, which are ultra-soft, breathable, and cool to the touch.

• Temperature-regulating comforters with Clima™ fibers, like the  TempTune Comforter, that adapt to your body temperature in real time.

• Cooling mattress pads, such as the  TempTune Mattress Pad, which help reduce trapped heat from foam mattresses.

Cool Down Naturally Before Bedtime

Your core body temperature needs to drop slightly for sleep to begin. A few simple habits before bedtime can help your body cool down naturally.

Try this:

• Take a lukewarm shower 1–2 hours before bed.

• Hydrate in the evening but avoid large amounts of water right before bed.

• Keep lights dim in the evening to promote melatonin production and natural cooling.

Wear Breathable Sleepwear to Stay Cool

Your sleepwear can make a big difference when it comes to regulating body temperature at night. Heavy or synthetic fabrics can trap heat and moisture, making it harder to stay comfortable.

For better sleep, choose loungewear made with:

• Breathable, moisture-wicking fabrics like TENCEL™ lyocell, which naturally feel cool and soft on the skin.

• Relaxed fits that allow air to circulate and reduce heat buildup.

• Lightweight layering pieces that offer comfort without bulk.

SIJO’s Eucalyptus Loungewear is designed for sleep and relaxation, using the same sustainable cooling fibers found in our signature bedding. It’s ultra-soft, thermoregulating, and ideal for warm nights—whether you're winding down or sleeping in.

Try fan favorites like:

• Relaxed SoftStretch Shorts

• Long Sleeve Top for added comfort when the AC is on

Improve Bedroom Airflow for Better Summer Sleep

A cool bedroom environment is key. Even without air conditioning, there are simple ways to lower the ambient temperature.

Tips for better airflow:

• Use a fan to circulate air—pointing it out the window can help draw in cooler night air.

• Try a DIY air cooler: place a bowl of ice in front of a fan.

• Sleep with windows open (if safe and weather-appropriate).

• Minimize electronics in the room, which can generate extra heat.

Choose Lightweight Layers That Breathe

You don’t need to skip the covers entirely—just choose lightweight, breathable layers designed for summer sleep. The right materials can provide softness and comfort without trapping heat.
