Cooling Blankets: The Secret to a Restful Sleep?

Sleep is an essential part of our daily lives, and the quality of our sleep impacts our overall well-being. When we don't get enough sleep, we can feel tired, irritable, and have difficulty concentrating. For some people, sleeping in a hot environment can make it difficult to sleep. Can using a cooling blanket help people sleep better?

Sleep is a complex process, and various factors contribute to the quality of our rest. Research suggests that a cooler sleeping environment, typically between 60°F to 78°F (15.8–26°C), can promote better sleep. Cooling blankets can assist in creating such an environment, especially during warm nights or for individuals who naturally run hot.

What is a cooling blanket?

A cooling blanket is a specialized bedding accessory that helps regulate body temperature during sleep. Unlike traditional blankets, which may trap body heat and lead to discomfort, cooling blankets are made from materials that efficiently disperse heat and moisture. The make of the blanket creates a cooler sleeping environment.

The secret to a cooling blanket's effectiveness is in its materials and construction. Most cooling blankets have fabrics that possess moisture-wicking properties and improved breathability. These materials actively draw sweat and moisture away from the body, allowing it to evaporate more quickly.

The cost of cooling blankets can vary widely based on factors such as brand, size, material, and additional features. Basic cooling blankets may start at around $50, while more advanced electric options can go up to several hundred dollars. It's essential to find the right balance between quality and affordability to suit your budget and needs.

Types of cooling blankets

When it comes to cooling blankets, there is a range of options available, each containing different technologies and materials. Let's explore some common types of cooling blankets:

• Cooling fabric blankets. Made from materials with natural cooling properties. Some popular choices include linen, eucalyptus, and bamboo. These fabrics are known for their breathability, moisture-wicking abilities, and ability to dissipate heat quickly.
• Phase-change material (PCM) blankets. PCMs are substances capable of absorbing, storing, and releasing heat as they change from one phase to another. In cooling blankets, PCMs are often embedded within the fabric or as separate inserts. PCMs were developed for astronauts to protect them from extreme temperatures in space.
• Air-cooled blankets. Feature a design that allows air to flow freely through the material, facilitating excellent breathability. These blankets often have unique patterns or constructions that promote better ventilation. The airflow helps carry away excess heat and moisture, keeping the sleeper cool and dry throughout the night.
• Water-based cooling blankets. Use a network of water channels or tubes within the blanket. These channels are either filled with cold water or connected to a cooling unit. The cold water circulates through the channels, absorbing heat from the body and providing a cooling effect. These blankets can be especially effective in maintaining a consistently cool temperature throughout the night.
• Gel-based cooling blankets. Contain gel inserts or gel-infused foam that provide a cooling sensation. The gel absorbs and dissipates heat, helping to regulate the body temperature. These blankets can be used on their own or in combination with other cooling technologies for enhanced cooling effects.

Risks of using cooling blankets

Generally, cooling blankets are considered safe for most individuals. However, there are a couple of potential risks to be aware of:

• Overcooling. Using a cooling blanket excessively or setting it to extremely low temperatures may lead to hypothermia. People who are temperature sensitive or with certain medical conditions should be cautious while using a cooling blanket.
• Allergies. Some people may be sensitive or allergic to the materials used in cooling blankets. It's essential to check the product's specifications and opt for hypoallergenic options if needed.
• Electric blanket risks. Some cooling blankets come with electrical components, and while safety features are built-in, it's crucial to follow the manufacturer's instructions and guidelines to reduce any potential hazards.

Can children or pregnant women use cooling blankets?

Children can generally use cooling blankets if they are designed with appropriate materials and safety measures. Younger children may not be able to communicate if they are being over-cooled and be placed at risk of developing hypothermia.

Pregnancy can cause fluctuations in body temperature, and it's essential to ensure the safety and comfort of both the mother and the baby. Cooling blankets are a good way to fight increased body heat during pregnancy. If using a cooling blanket, ensure you are not over-cooling your abdomen. Extreme temperatures can increase the risk of preterm birth.

Alternatives to a cooling blanket

While cooling blankets can be effective for some, they may not be the best solution for everyone. If you find that a cooling blanket doesn't suit your preferences, there are other methods to create a cooler sleep environment:

• Adjust the thermostat. Lowering the thermostat or using a fan can help cool down the room and create a comfortable sleep environment.
• Breathable bedding. Opt for bedding made from natural fibers like cotton or bamboo, which are more breathable and less likely to trap heat.
• Wicking sleepwear. Wear moisture-wicking sleepwear to keep your body dry and cool during the night.

A cooling blanket can help improve sleep quality for individuals who struggle with night sweats. Hot flashes, or running hot during sleep. By creating a cooler sleeping environment, cooling blankets support the body's natural temperature drop during slumber, leading to potentially better overall sleep quality and morning refreshment.
