Excessive caffeine consumption can cause tingling in the hands as well as difficulty sleeping, fatigue, anger, depression and irritability, explains WebMD. Caffeine stimulates the central nervous system and can cause mild physical dependence.
The body absorbs caffeine quickly, explains WebMD. Approximately half of the caffeine is eliminated from the body within five to seven hours, which can help to minimize tingling in the hands or symptoms of excessive consumption.
People who consume excessive caffeine on a regular basis may experience withdrawal symptoms when they stop drinking caffeinated beverages such as coffee, tea or soda, according to WebMD. Common withdrawal symptoms include fatigue, anxiety, headaches and irritability.
