Why Your Baby Feels Hot While Sleeping and What to Do About It

Many parents struggle with understanding why their baby feels warm during sleep and finding effective solutions to ensure their comfort. It's crucial to address this issue, not only to promote better sleep quality for babies but also to prevent potential health risks associated with overheating.

Understanding Baby Overheating

Babies are much more sensitive to temperature changes compared to adults. This sensitivity can often lead to overheating, especially during sleep when they are wrapped in swaddle or blankets and their bodies are still working on developing efficient temperature regulation.

Overheating in babies can be caused by several factors including excessive bedding, warm room temperatures, or even the baby's pajamas and sleep environment. Understanding these triggers is the first step in preventing your baby from overheating.

Signs of Overheating in Babies

To ensure that your baby remains at a comfortable temperature throughout their sleep, it's important to be aware of the signs of overheating. These signs could include:

  • Sweating or damp hair
  • Flushed cheeks
  • Rapid breathing
  • Heat rash
  • Restlessness

Should you notice any of these signs, it's advisable to immediately check and adjust the temperature in their room, their clothing, and their bedding.

Optimal Sleep Environment for Your Baby

The ideal room temperature for a baby to sleep comfortably is between 68 and 72 degrees Fahrenheit (20 to 22 degrees Celsius). It is essential to maintain this temperature range and monitor the room for any significant changes, especially during summer or winter months.

Managing light and external noise also plays a pivotal role in creating an ideal sleep environment. Blackout curtains can be exceptionally effective in controlling room temperature and blocking out unwanted light and noise that might disturb your baby's sleep.

Benefits of Blackout Curtains for Babies

Blackout curtains offer numerous benefits for babies, particularly in creating a conducive sleeping environment:

  • Temperature control: They help in insulating the room, thereby maintaining a consistent temperature that's conducive for your baby’s rest.
  • Light blocking: They can block out up to 100% of sunlight and other external lighting, aiding in longer and more restful sleep.
  • Noise reduction: Certain blackout curtains also have the capability to reduce noise, further enhancing the sleep environment.

Sleepout Home Blackout Curtains are a perfect solution to ensure your baby's room remains dark, quiet, and at a suitable temperature.

Other Tips to Keep Your Baby Cool While Sleeping

  • Appropriate clothing: Dress your baby in light, breathable fabrics like cotton. Avoid over-layering with too many clothes or heavy blankets.
  • Proper bedding: Opt for light, breathable fabrics for bedding as well. Ensure that any swaddling is not too tight or thick.
  • Avoid direct air conditioning: Direct blasts of air conditioning can be too intense for babies. If using air conditioning, set it on a mild temperature, or use a fan to circulate the air effectively without direct exposure.
  • Hydration: For babies who are on solid food, ensuring they have proper hydration can help keep them cool. For younger infants, regular feeding times generally ensure adequate hydration.

Monitoring and Adjustment

Regularly monitoring the sleep environment is essential to providing a safe and comfortable atmosphere for your baby. Consider using an indoor thermometer to keep track of the room temperature and adjust your AC, heating, or additional cooling methods accordingly.

Every baby is different and may require slight variations in their sleeping environment. Pay attention to how your baby responds to changes and adapt as needed to ensure they are always comfortable, safe, and positioned to sleep well.


Understanding the causes of baby overheating and implementing appropriate measures to prevent it are crucial for the health and comfort of your infant. Using blackout curtains like the Sleepout Home Blackout Curtains, alongside optimizing the bedroom environment, will help create the ideal conditions that support healthy, restful sleep for your baby.

Creating a soothing sleep environment will not only benefit your baby but also improve the quality of sleep for the entire family. By taking these steps, you can ensure your baby sleeps safely and soundly, night after night.

Remember, a cool, dark, and quiet environment is key to helping your baby achieve the best sleep possible!
