Ever got up at about 3:00 AM and suddenly felt quite warm? The room is regular, and your blanket does not even shift. Suddenly, you are not comfortable enough. You push the covers aside or turn your pillow to find a cooler place.
This occurs frequently to most individuals, even without their knowledge. Sleep experts refer to it as a nighttime thermal spike. The body temperature leveling changes when sleeping. At an approximation of 2-3 am to 4 am, when you are asleep, your body shifts between deep sleep and REM sleep.
Your internal temperature increases very slightly during this period because it is during this period that the brain is preparing to have subsequent sleep cycles.
In case there has been an accumulation of heat under your body quickly picks it up and, in the process, takes a minute to cool you. That is why there are some individuals who get up almost at the same time at night. In most of the cases, it is not the sleep habits that cause it, but it is usually the surface one is lying on.
The 3 AM Thermal Spike Explained
There is a natural circadian tempo within your body. Thus, the temperature increases and decreases during the night. At the beginning of the night, the body temperature becomes low, assisting the body to relax and sleep. However, in the late hours and in the early morning, the temperature starts rising once again when the body is ready to open its eyes.
This movement usually happens when the person is in REM sleep, when the brain activity is heightened. When the body is more sensitive to heat. Then it would be confined by your mattress or bedding at this stage.
Even a little accumulation of heat can interrupt sleep. It can be caused by a somewhat warm bedroom, thick blankets, or warm mattresses. Due to this, one of the most significant, though least considered, factors in the quality of sleep is temperature control.
Why Your Mattress Might Be the Real Issue
In the process of trying to enhance sleep, individuals tend to pay attention to pillows or blankets first. The largest source of heat is, however, usually the mattress itself.
The body heat is trapped in many traditional mattresses. Particularly, the older foam beds. Memory foam molds are also the ones that fit into the body and are comfortable. But they can block airflow.
As the night goes on, there is heat accumulation between the body and the mattress surface. At the beginning of the night, this warmth might be good.
However, in the early morning change of temperature, there can be an abrupt disturbance of sleep due to trapped heat.
When this occurs frequently, sleep becomes less deep and restful. It is a difference that can be made in the quality of your nighttime sleep.
The Cooling Layer Many Beds Are Missing
A basic method of warming bedtime up is by placing a breathable blanket between the body and the mattress. It is here that an attractive topper can come in.
The Straight 2 Sleep Mattress Topper is aimed at enhancing the comfort and airflow in the bedroom. It is able to distribute body weight equally to ease the joints and muscles, compared to the dense foam layers that hold the heat in. It causes the surface to circulate the air more effectively, distributing air uniformly over the surface.
This equilibrium allows keeping the temperature in the room cooler and more comfortable at night.
Small Temperature Changes Matter
When a person is asleep, the body is very sensitive to temperature. Even the slight rise in heat can disrupt the deeper sleep phases. This is the reason why sleep gurus usually suggest that bedrooms should be cool.
Nevertheless, temperature is not always sufficient at room temperature. The material of your bedding and mattress also determines the ability to escape heat during the night.
Breathable fabrics, supportive foam construction, air-friendly designs, etc., can help provide a more secure sleeping environment.
3 Simple Ways to Reduce Nighttime Overheating
Enhancing the sleep temperature does not need a complete upgrade of the bedroom. A few simple changes can help.
- 1. Select breathable bedding. Organic materials such as cotton or bamboo permit the heat and moisture to evaporate more easily.
- 2. Do not use warm-up materials. The thick synthetic layers and old foam mattresses tend to keep the heat near the body.
- 3. Better the sleeping surface. Airflow and pressure support are provided by a cooling topper, such as the Straight 2 Sleep.
All these minor modifications can be used to make the sleeping environment colder and more comfortable.
Conclusion
The reason can be even simpler than it might seem in case you wake up around 3 AM, frequently feeling too warm.
There is a natural change of temperature in your body during sleep cycles. When your mattress has an amount of heat, that change will be too unpleasant to sleep. The issue can be resolved by making the sleep surface cooler.
Other solutions, such as the Straight 2 Sleep Mattress topper, have been engineered to provide pressure relief along with higher airflow, to ensure that the sleep temperature at night is kept in balance. All you need to do is modify your bed arrangement to get your troublesome nights to change to a smooth sailing sleep.
