How can drinking alcohol lead to hypothermia?

Answer 1

No. However - drinking causes one to "feel hotter" and therefore wearing less clothing resulting in a lower core temperature than usual.

Actually, it does make you lose body heat. The blood vessels close to your skin dilates,(widens) allowing more blood going to your skin, thus losing body heat. You feel hotter because the nerves close to your skin, (The ones that feels the heat) still felt heat, so it assumes that you're actually hot while you are losing your heat.

Answer 2

Drinking alcohol helps the body dissipate heat.

Answer 3

Alcohol consumption results in loss of body temperature: it makes you slightly colder, even though you feel warmer.
