Exposure to cold temperatures can cause facial numbness. In extremely cold environments, you may be at risk of developing frostbite.

According to the Centers for Disease Control and Prevention, frostbite can cause a loss of color and feeling in your skin. Your extremities and any exposed skin, including your face, may particularly be affected.

Treatment for cold exposure

The most important factor for treating numbness resulting from cold temperatures is getting to a warmer environment. Applying body heat or warm water to the affected area can be beneficial.

Never use a heated tool, like a heating pad or radiator, to warm your skin. The skin numbness can make it difficult to determine if these tools are too hot and causing damage.

One common initial symptom of MS is numbness, which can occur in the face, trunk, or extremities. MS is a disease that damages the protective covering of the nerve cells. This damage can also cause other nerve-related symptoms like tingling or pain.
