Cool Jams Helps You Get Your Beauty Sleep in Summer Heat
A good night’s sleep is important for everybody’s health. However, many women suffer from waking up at night being bathed in sweat due to menopause as if hot muggy summer nights are not enough already to rob your sleep.
Sweating Is Not Bad …
The human body reacts with perspiration to exercise and/or hot environmental conditions. The sweat evaporates on the skin thereby cooling the body. This genius bio-physical concept works fine when air temperature and relative humidity are in a moderate range. However, evaporation of sweat strongly decreases when the relative humidity in the environment increases. This happens for instance, when a fabric captures moisture and heat between itself and your skin (see schematic view below). Thus, dressing for the Dog Days is a challenge.
… But the Right Fabric Is a Must
Scientific research emphasizes that fiber type, yarn properties, fabric structure, finishing, knit structure, and the cut of the clothing affect the thermal-physiological comfort of a person. Such research led to the development of the Moisture Transference System (MST) technology fabric.
Cool-jams Inc. crafts their sleepwear and bedding using this fabric. This means while you can’t change the weather or switch off hot flashes, you at least can ensure optimal discharge of your body heat, and obtain best evaporation conditions for sweat with the choice of your sleepwear and bedding.
How Does MTS Work?
Fast Removal of Heat and Moisture Ensures Thermal Comfort
For a sense of coolness even on warm or muggy summer nights or during hot flashes, the body heat and evaporated sweat must be able to penetrate thru the fabric to the outside. The lower a fabric’s resistance is to the transport of evaporated sweat the more comfortable is its sensation. A low resistance to water vapor transport also ensures that sweat can already evaporate on you skin and provide evaporative cooling.
It is obvious, that water vapor penetrates faster thru a thin than thick fabric. As a consequence, Cool-Jam’s MTS fabrics make use of both aspects. They are thin and permit fast water vapor transport.
Pro tip: Never use fabric softeners on your Cool-Jams Inc. pieces. Recall fabric softeners are designed to cover the fibers. This means that fabric softeners reduce or even clog the fabric pores and hence block water vapor transport.
Pro tip: If by accident a piece got into a wash with fabric softeners, just re-wash the piece again, but without softener. The piece will then perform as effectively as before.
Wicking Provides Additional Benefits for Thermal Comfort
The Cool Jam Ins MTS fabric is also wicking, which means it quickly takes up sweat. Consequently, your body can achieve cooling by further perspiration. In addition, the fabric cools by evaporation of the sweat. These properties provide two benefits: You don’t feel bathed in sweat, and the area for evaporation increases (your skin plus the fabric) thereby providing more cooling. 🙂
Cool Jam Inc.’s Pieces Feel Cool at First Touch
Comfort has not only a thermal-physiological, but also psychological and sensorial aspects. The warm-cool feeling of fabrics, i.e. the first sensation, is measured by its thermal absorptivity. When you touch a garment that is at a different temperature than your skin, your skin and the fabric exchange heat. Fabrics with high thermal absorptivity feel cooler at first contact than those with low thermal absorptivity. Smooth fabrics have a large surface area between the fabric and skin, which causes a cool feeling. A large surface area also means an increased area where evaporation may occur.
Cool-Jams Inc.’s sleepwear is made of such fabric that feels soft and cool on your skin. Pulling on a Cool-Jams PJ, for instance, gives you a relaxing feeling of coolness. And who doesn’t love to lay down in a cool-feeling bedding after a long day of hard work?Stay cool at night in the summer heat with Cool Jams PJ. #health #beauty Click To Tweet
The Comfort of Feeling Beautiful
A psychological aspect of comfort is that you feel beautiful in your clothes. The cut of Cool Jams Inc.’s sleepwear is semi-fitted. It is loose enough to not squeeze, but not too loose that you lay on a mountain of folds. The cuts are classic and the colors are modern – an ageless style.

Cool-jams’ PJs and night gowns certainly meet the comfort criterion of being well dressed, don’t you think so too?
Cool Comfort Is Affordable Even on a Budget
Cool jams cost about the same as conventional sleepwear. Thus, why not buying cool jams that bring you thermal-physiological, and sensorial comfort in addition to looking great?
Thermal Comfort Sleepwear in Summary
The wicking, wettability and speed of drying properties of the Cool-jam fabric are designed to optimize thermal comfort – a pre-requisite for relaxing sleep.
Give yourself the comfort of coolness at night and/or during exercising and the feeling to look great, start shopping Cool Jams’ thermal comfort sleepwear collection and bedding. You owe yourself a good night rest after a day of work!
