Why am I cold in my sleeping bag?

The temperature specifications for sleeping bags are determined by a neutral institute determined uniformly for all manufacturers.

The decisive factor is the Comfort value, which indicates the lowest temperature at which it is still comfortable to sleep in a sleeping bag. However, even at this temperature, it can already get slightly chilly.

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.
