Modern technology can help improve virtually every aspect of our lives, including exercise habits and physical condition. People of all ages and from all walks of life can be seen wearing colorful “smart” wristbands or trendy smartwatches as they go about their daily activities. Called fitness trackers, many people use the wristbands to create records of their physical activities, such as the number of steps walked, miles run or laps swum in a pool. Most of today’s smartwatches have similar activity tracking capabilities. The data gathered by the devices is used to help these people achieve personal fitness goals and improve their overall physical condition. Both types of trackers gather and store summaries of the day’s activities by interacting with smartphones and other digital devices via Bluetooth.
Digital tracking devices aren’t limited to monitoring walking, jogging or other daytime exercise and fitness activities. Regularly getting a good night’s sleep is essential to achieving and maintaining good physical and mental health. Sleeping poorly can result in decreased motivation for achieving goals, increased cravings for junk food and sugar, as well as a higher risk of illness due to the negative effects too little sleep has on the immune system. Many people who consistently have trouble sleeping are now using digital sleep trackers to record the time they fall asleep, when and how often they wake up during the night and how much time they actually spend sleeping.
