Many people get cold hands or feet, which often are bothersome but not a serious health problem. You are more likely to feel cold easily if you:
Do not have much body fat. Fat under the skin helps keep you warm. People who have low body fat may be more likely to get hypothermia. Babies, older or ill adults, or malnourished people have low body fat.
Smoke cigarettes or drink caffeine. Nicotine (from tobacco) and caffeine cause narrowing of the blood vessels in the hands and feet. When blood vessels are narrowed, less blood flows to these areas, causing the hands and feet to feel cold.
Are under a lot of stress or feel tired. Chronic stress or anxiety can cause your nervous system to release adrenaline, which acts to narrow the blood vessels that supply blood to the hands and feet.
