Why am I cold in my sleeping bag?

Temperature ratings for sleeping bags are determined uniformly for all manufacturers by a neutral institute .

The crucial factor is the comfort rating , which indicates the lowest temperature at which it is still comfortable in the sleeping bag. However, it can already get slightly chilly at this temperature.

But why do we sometimes still feel cold? There are several reasons for this:

• One is cranks.
• Man hat I ate too little.
• Male goes into the sleeping bag coldA sleeping bag is not a heater; it merely reflects body heat. Therefore, it is advisable to move around a little before getting into it to warm up your body so that the sleeping bag can reflect the heat more effectively.
• You use the wrong sleeping mat or sleeps on a non-insulating surface such as an air mattress, a camp bed, or on a thin mat in a VW van. In these cases, the cold can penetrate from below, as a sleeping bag only insulates from above. The sleeping mat should therefore always have a higher insulation value than the sleeping bag.
• You come from a warmer to a colder country, which can increase the feeling of cold because the temperature difference is too great.
