Sometimes sleeping in a colder room even contributes to the symptoms of arthritis and fibromyalgia.Hot sleepers tend to experience night sweats and frequent wake-ups caused by a room or bed that is too warm. In this article, we will discuss how body temperature relates to sleep, and we’ll look at some ways to warm up or cool down at night.Body Temperature and SleepThe body’s temperature rises and falls over 24 hours and contributes to the body’s sleep-wake cycle. Our core body temperature stays around 98.6 degrees Fahrenheit (37 degrees Celsius) but fluctuates by about 2 degrees while sleeping.As bedtime approaches, your body temperature drops, coinciding with the release of melatonin. Melatonin is a sleep-promoting hormone that prepares you for a good night’s rest. During sleep, your body temperature continues to drop, then gradually warms up as the morning progresses. This temperature spike stimulates your alertness and wakes you up each morning.While you are sleeping, keep your room at a comfortable temperature to avoid disruptions. Sleeping in a too-hot room causes discomfort and restlessness for many.Researchers say a higher core body temperature is typically associated with decreased restorative slow-wave sleep. On the other hand, sleeping too cold makes it difficult to relax and get comfortable in bed.Best Mattresses for Hot SleepersIt’s common for hot sleepers to experience night sweats if their sleeping surface is too warm. For this reason, the best mattresses for hot sleepers are hybrid beds or latex mattresses because they feature cooling technologies to dissipate body heat.Hybrid mattresses have body-hugging qualities, similar to memory foam, but also have a pocketed coil system, which provides more airflow. Latex mattresses are also a good choice since they deliver bouncy comfort.Additionally, natural latex foam has breathable properties that allow more air circulation throughout the mattress. Also, the comfort layers have tiny air pockets to boost airflow. Plus, latex does not absorb body heat like other synthetic materials.Memory foam mattresses are some of the most popular mattresses on the market, but they are not always suitable for those who sleep hot. These beds do not provide good breathability like other mattress types and often cause sleepers to overheat. However, memory foam beds infused with gel are designed to keep hot sleepers more comfortable, and many companies are incorporating more gel foam in their products.Best Mattress for Cold SleepersWhile some people criticize traditional memory foam for its lack of air channels, cold sleepers can use this to their advantage. Since memory foam beds retain heat and create a warm sleeping surface, they are better suited for cold sleepers. Sleeping in an extra cozy bed might keep you from shivering or reaching for blankets throughout the night.Hybrid mattresses also consist of a foam top with innerspring coils below. These beds can keep your bed feeling cozy since the foam layer is closest to your body. Hybrid mattresses also have excellent responsiveness and are a great alternative to the sinking feeling of a memory foam bed.How to Stay WarmCold sleepers need to stay as warm as possible throughout the night.
