Obesity is becoming a common cause of cirrhosis, either as the sole cause or in combination with alcohol, hepatitis C, or both. Many people with cirrhosis have more than one cause of liver damage. Cirrhosis is not caused by trauma to the liver or other acute, or short-term, causes of damage. Usually years of chronic injury are required to cause cirrhosis. Alcohol-related liver disease. Most people who consume alcohol do not suffer damage to the liver.
Many trackers can also serve as a digital watch. An activity tracker is a device or application for monitoring and tracking fitness-related metrics such as distance walked or run, calorie consumption, and in some cases heartbeat and quality of sleep.
Fitness trackers' ability to measure sleep often comes from sensors called accelerometers, which detect a wearer's motion, along with the speed and direction of that motion. Experts say that while most trackers can in theory tell when a person is awake versus asleep, they are prone to mistakes.
