Technology is always moving forward. Sometimes, the advancements are fun like virtual reality games, but sometimes technology can save lives.

It might seem like something out of a science fiction movie, but smart fitness trackers can actually predict or detect health issues, such as the following.

Irregular Heartbeat

The heart is a powerful muscle that cannot be obstructed. The problem is diet or other health issues can sometimes lead to irregular heartbeat rhythms.

A fitness tracker can record these irregularities, which could tell the user his or her heart is having a hard time beating. This could point to artery blockage amongst other things. People really want to pay attention to any irregularity and have the fitness tracker save this information so they can give it to their health care professional.

Weight Issues

Wearables can detect weight loss and gain, which could be telling a user to change his or her diet. For example, unexplained weight gain could mean the body has too much sodium and may be dehydrated.

A little more water could help flush out this weight. If more water doesn’t help, it could be signaling kidney disease or heart issues. Unexplained weight loss could be a warning of issues like diabetes or even cancer. Of course, these issues are some of the extreme problems linked to weight fluctuations. Having this information can also help people avoid being overweight or underweight.

Stress Control

Stress elevates heartbeat, and it does so consistently. A wearable can tell a user how much stress is affecting the body. Keep in mind that too much stress releases cortisol, and too much of that can lead to heart problems and hormonal imbalances.

A user can use this information to try to combat stress in effective ways; for example, a person can use meditation or yoga to try to control elevated heartbeat rhythm. The wearable can tell a user that these tactics are working by simply reading the wearable.

These are just some of the things fitness trackers can do for the public. The technology is probably going to continue to get better as time moves on; that should help make the public even healthier as wearable technology becomes more commonplace.
