ROCKFORD (WIFR) -- While you're finishing your Christmas dinner use this time to relax doctors want us to be aware of "Holiday Heart Syndrome".
"Holiday Heart Syndrome" is an irregular and faster heartbeat which can occur in people who are usually healthy.
It's caused by stress, excessive drinking and cold weather. The symptoms include fatigue and black outs. Dr. Andrew Kotis says cold temperatures cause arteries to constrict which could lead to a stroke.
"It is one of those conditions they may not feel it unless they have the more serious symptoms, blackouts or having a heart attack or a stroke with it," Kotis said.
Kotis says serious cases of "Holiday Heart Syndrome" are treated with medication.
