Cold hand warm heart
The core of the body is warmest.
As you move away from the heart
, the temperature drops. Since the hands are furthest from the heart, they are the coldest. While the normal core body temperature is 98 degrees fahrenheit, the hands typically are 20 degrees colder. This is why patients with raynaud's disease
tend to have cold fingers-they are furthest from the heart. Exercise
can help. Wear gloves.
