Minimizing heat loss through conduction is primarily achieved by creating a barrier between the body's heat and the surfaces that draw heat away. Insulation from surfaces prevents direct contact, which is crucial since conduction involves the transfer of heat from a warmer object (the body) to a cooler one (the ground or another surface) through direct contact.

In practical terms, wearing insulating materials such as foam pads or thermal blankets can significantly reduce heat loss by providing effective barriers that trap heat close to the body. This reduces the temperature gradient between the person and the surface, thereby limiting the transfer of heat.

Other options, while beneficial in certain contexts, do not directly address conduction. For instance, using hot packs generates heat but can primarily assist with pain relief rather than preventing heat loss. Increasing air movements can be effective in dispersing heat but might actually increase heat loss through convection rather than conduction. Wearing light clothing typically provides minimal insulation and is not effective in retaining body heat in cool environments.
