Hi
He could be anemic:
Certain diseases and medications can cause the number and percentage of red blood cells to fall below normal levels. When a person becomes anemic, the body tries to compensate in a number of ways. The heart rate increases in an attempt to get more blood, and more oxygen, to the tissues, putting an increased burden on the heart muscle. The respiratory rate also increases. Certain capillary beds (tiny blood vessels in the tissues) open up wider in an attempt to provide more oxygen to vital tissues, while other capillary beds constrict (get smaller) in an attempt to preserve oxygen. This redistribution of blood leads to the common paleness and cold sensation of people with anemia, but provides more oxygen to critical organs such as the heart, brain, and muscles. Increased activity, however, produces and even greater need for oxygen in these tissues, resulting in a sensation of fatigue, weakness, palpitations, shortness of breath, and other symptoms.

He could also have a pinched nerve in his neck, causing cold sensations.
hope that helps,
