When choosing thermal pajamas, it is important to consider the circumstances under which you will be wearing them. If a person is sleeping in a home with adequate heating, the considerations in choosing thermal pajamas are primarily those of comfort and aesthetics, such as the softness of the fabric used to make the pajamas. In situations where an individual will be sleeping outdoors or in an unheated shelter, the ability of the pajamas to keep that person warm and to protect him against both frostbite and hypothermia is the most significant concern. Other issues include making sure that the wearer actually likes the way the pajamas look as well as their cost.
For many people, comfort is an important aspect of getting a good night's rest. Thermal pajamas, which are typically designed to retain body heat, can help people stay warm at night and thus enjoy quality sleep. If selecting thermal pajamas for yourself or a loved one for sleeping in a heated home, you may want to consider the average temperature in the area so as to select pajamas made of a suitably heavy material. You should also consider the issues of fit and comfort. A material that keeps someone warm while also proving to be scratchy and uncomfortable is not suitable for pajamas. If you can't try on a pair of pajamas at the store, keep the tags on until after you try them on at home and know that they are something that you can wear on a regular basis.
If you purchase thermal pajamas for use while camping or living in a home that lacks adequate heat, your concerns are radically different. A good pair of thermal pajamas, in combination with other camping gear and clothing, can help ensure your health and well-being. Before purchasing your pajamas, talk to campers who have actually been to the area in which you plan to camp. As you do your research, find out about the average nighttime temperatures and talk to reputable camping gear sellers about your options. Some may suggest that you sleep in layers of clothing, which may include long underwear as well as thermal socks and pajamas. As a general rule, it is a good idea to avoid cotton clothing and pajamas when in cold climates, as garments made from cotton offer poor, if any, insulation when wet and can actually lower your body temperature.
