Summers in Austin can be brutal, with triple-digit temperatures that don’t always cool down at night. If you’ve ever found yourself tossing and turning in the heat, you’re not alone. The summer heat can significantly impact sleep quality, making it harder to fall and stay asleep. At Sleep Medicine Consultants, we understand how vital restful sleep is to your health. In this blog, we’ll explore the effects of heat on sleep and provide expert tips to help you stay cool at night—including some local Austin businesses that can help you sleep comfortably.
How Does Summer Heat Affect Sleep?
1. Increases Sleep Latency (Time to Fall Asleep)
High temperatures make it more difficult for your body to cool down, which is essential for initiating sleep. Normally, our body temperature drops slightly before bedtime to signal that it’s time to rest. However, in hot conditions, this natural cooling process is disrupted, making it harder to fall asleep.
2. Causes More Nighttime Wake-Ups
Even if you manage to fall asleep, overheating can cause frequent awakenings throughout the night. Excessive sweating, dehydration, and discomfort from heat exposure can lead to restless sleep, reducing the amount of deep and REM sleep you get.
3. Reduces REM Sleep
REM sleep, the stage associated with dreaming and cognitive restoration, is particularly sensitive to temperature changes. If your bedroom is too warm, you may experience shorter REM cycles, leading to grogginess and difficulty concentrating the next day.
4. Leads to Increased Fatigue
When your sleep quality suffers due to heat, you may wake up feeling unrested and fatigued. This can affect your mood, productivity, and overall health.
How to Stay Cool at Night in Austin’s Summer Heat
1. Optimize Your Bedroom for Cool Sleep
- Use breathable bedding: Swap out heavy blankets and flannel sheets for lightweight, moisture-wicking fabrics like cotton, bamboo, or linen.
- Invest in cooling sleep products: Cooling pillows, mattress toppers, and gel-infused memory foam mattresses can help regulate body temperature.
- Blackout curtains: These help block out heat from the sun, keeping your room cooler throughout the day.
🛏️ Where to Buy in Austin:
- Urban Mattress Austin – Offers a variety of cooling mattresses and sleep products.

- The Container Store (The Arboretum, North Lamar) – Sells blackout curtains and cooling bedding.
2. Keep Air Circulating
- Use a box fan or ceiling fan to circulate air.
- Place a bowl of ice in front of a fan to create a DIY air conditioner.
- Open windows during cooler hours (early morning and late evening) to let in fresh air.
🌀 Where to Buy Fans in Austin:
- Breed & Co. (Westlake, 29th St.) – Sells high-quality household fans.
- Home Depot (various locations) – Wide selection of cooling fans.
3. Cool Down Before Bedtime
- Take a lukewarm (not hot!) shower to help lower body temperature.
- Drink a glass of cold water before bed to stay hydrated.
- Use a cold compress on pulse points like the wrists, neck, and behind the knees.

4. Adjust Your Sleeping Position & Clothing
- Sleep in a spread-out position to minimize body heat retention.
- Wear lightweight, loose, and moisture-wicking pajamas.
5. Turn Off Heat-Producing Electronics
Electronics like laptops, gaming consoles, and TVs generate heat. Try unplugging them an hour before bed to reduce excess warmth in your room.
Q&A: Your Sleep & Summer Heat Questions Answered
Q1: What’s the best bedroom temperature for sleeping in the summer?
A: The ideal sleep temperature is between 65-69°F. If you don’t have AC, a cooling mattress pad, a fan, and lightweight bedding can help regulate your body temperature.
Q2: Can sleeping in the heat cause dehydration?
A: Yes! Sweating excessively at night can lead to dehydration, which may cause headaches, dizziness, and fatigue in the morning. Stay hydrated throughout the day and drink a glass of water before bed.
Q3: Is it bad to sleep with a fan blowing directly on me?
A: While fans can help circulate air and keep you cool, direct airflow can sometimes dry out your skin and sinuses. If this happens, try using a humidifier or adjusting the fan’s direction.
Q4: What are the best natural ways to cool down at night?
A: Besides taking a cool shower and using breathable bedding, try keeping a bowl of ice near your bed or sleeping with a damp washcloth on your forehead.
Q5: Can heat affect sleep apnea symptoms?
A: Yes. Heat and humidity can make breathing more difficult, worsening sleep apnea symptoms. Using a CPAP machine with a built-in humidifier or a cooling pillow can help.
