Sleeping cool can be the single one thing to help many be able to drift off to the restful bedtime. Whether it is the heat of weather, or an overactive heating system, sweat and falling to sleep do not work well together – causing tossing and turning, and endless waking in an effort to get comfortable.

Not everyone is fortunate to have air conditioning, or perhaps happen to be caught up in an unexpected heat wave. Those battling heat to achieve dreamland are constantly seeking a remedy of a magic position to cool off for bed. Along with tips and cooling gadgets, it is important to buy a mattress that works to cool as an avenue to provide comfort and a great sleep.

I. Benefits of Sleeping Cool

Insomnia Relief

Rolling around in the heat on a hot bed is not going to inducive to finding peaceful sleep. Insomnia has been linked directly to the body’s temperature rising to high levels when attempting to rest. Heat can jolt one awake whereas a cooler surrounding will give comfort to the body allowing it to drift off peacefully. Normalizing the body temp, by cooling it down, will lead to falling to sleep faster and staying asleep throughout the night.

Boost Metabolism

Want to achieve a metabolism boost, and perhaps lose a couple of pounds, then you will want to seek out a cooler sleep environment. Sleeping cool has been seen to increase the good fat, known as brown fat, that works to burn calories. When calories are expended then metabolic health is improved, thus, helping with weight loss and reducing risk of metabolic diseases, such as diabetes.

Cancer prevention

Along with giving the body a health inducing metabolic boost, sleeping cool also helps to raise melatonin levels in the body. Along with assisting in achieving a younger appearance, growing the melatonin production also helps in dropping one’s risk of cancer. It has been seen that blood lacking melatonin promotes tumor development, yet blood that is rich in melatonin actually-reduces the growth of tumors. To work on preventing cancer it is important to sleep in a cooler room to help increase melatonin levels.

Less Stress – Better Mood

A comfortable, good quality sleep is known to regulate the levels of the stress hormone called cortisol. A hot room that causes poor sleep works to increase the cortisol production that leads to depression. By achieving a cool sleep environment, one is making the room the optimal temperature for drifting off to dreamland in a quick and relaxing manner. Sleeping cool allows for the best of rest to assure that the body and brain has the best rest possible which leads to reduced stress and a better mood.

II. Sleeping Cool Tips

Cotton is Best

Think 100-percent cotton and leave out the polyester if you are looking for the best bedding that will aid in a cooler sleep. Sleeping between light-colored, all natural, cotton sheets surround the body with a breathable environment that works to ventilate and promote airflow for cooling. Choose a high thread count if you want a luxurious cooler sleep.

In the Nude, or Close

The more bed clothes that one has on, the more the heat has a place to get trapped for a sweaty night. Get free and slip into bed naked. The skin will breathe better between the cotton sheets to allow for a cooler sleep. For those who prefer being dressed for bed, choose loose fitting, all cotton, night apparel – such as a simple night shirt, or a tee and shorts – that will allow for the air to flow around the body.

Quick Cool Freeze

Want a quick trick that has been handed down for generations looking for a trick to get cool? Simply apply ice to the body’s pulse points. Place a cold pack, or a piece of ice, to pulse points at the wrists, neck, and elbows, or behind the knees and ankles.

Fan the Cool In

Not everyone has the comfort of an air conditioner available to cool down a room for sleep. For those without an AC, a fan is a wonderful option for getting a cooler breeze going. If possible, create a cross-breeze to get the optimal cooling affect. Place the fan across from a window so that air blows over the bed towards the window.

III.Gadgets to Help Sleeping Cool

Cooling Pillow Mat

For those seeking to rest a weary head on comfort ready for a sleep filled cool night, then top a favorite pillow with a mat designed to cool. A get cooling mat offers cooling convenience that can even be easily taken along when traveling. The mat works to disperse heat away from the head to allow for a cooler sleep.

Bed Fan

Instead of attempting to position a fan just right to get air directed at you, why not use a fan made specifically to cool the bed that one is sleeping upon. The BedJet’sis a fan made for a bed. The nozzle is placed strategically on the mattress to blow air into the bed for a cool consistent temperature. This even works great for those sleeping with AC who need a bit more cooling help when sleeping.

Special Bedding

Okay so optimally the best sheets are 1000 thread natural cotton, but cotton will absorb sweat and not wick hot moisture away from the body. Sheex bedding is designed with a special fabric technology crafted to specifically help to keep people sleeping cool. The fabric has an “enhanced breathability and advanced thermoregulation” that works to keep the body dry and cool.

Cool Pad

Just as you can lay a pad atop the pillow for cooling, there are also pads made to place on a mattress for cooling benefits. The ChiliPad Cube mattress pad uses a temperature controlling system made for cooling in mind. It works by circulating water throughout zones of micro tubes. This allows for a regulated cool temperature that will promote a restful sleep.

IV. Sleeping Cool FAQ’s

What room temperature is the best to get great sleeping?

The optimal room temperature is one that will match the internal body temp that is naturally lowered during sleep. Keeping in mind that no two bodies are alike, experts agree that sleeping in a room that is between 65 – 72-degrees Fahrenheit is the best range of temperature for a good sleep. Loss of sleep is experienced when one is fighting a too hot room to get the body temperature down.

Can a mattress really-affect whether one is sleeping too hot?

Mattresses are no long one-size-fits-all. With the invention of the memory foam mattress came a new-found comfort but also complaints of heat retention. Now mattress companies are designing beds specifically for cooling comfort to allow for the best sleep possible.
