Many home blood pressure monitors are not validated for accuracy, which means there's no way to know if information they provide is correct. Relying on inaccurate measurements can affect decisions people make about medical treatment. Fortunately, reliable organizations have developed lists of blood pressure monitors that have demonstrated clinical accuracy. If a blood pressure monitor isn't listed, it's probably not validated.

Data from apps or wearable devices can help people spot patterns, track changes, and notice potential problems earlier—information that’s valuable both between and during clinician appointments.

A 2025 review of past research found that electromagnetic field exposure from electric cars poses no immediate health risks for people with implanted heart devices, such as pacemakers or implantable cardioverter-defibrillators.

Transcranial magnetic stimulation (TMS) uses magnetic pulses to repeatedly activate areas of the brain involved in mood regulation. Updated protocols hold the promise of rapid relief from major depression.

Home health technologies have made it easier for people to monitor their health at home. These handy home devices can track certain health markers, such as blood pressure, blood sugar, heart rhythm, heart rate variability, and oxygen saturation. Checking this information periodically may help some people identify possible problems or manage existing conditions.

Several tools can help people with incontinence stay dry and comfortable. Tools can include medications; basic supplies, such as protection pads, leakproof underwear, adaptive clothing, and portable urinals; bedwetting alarms; and bathroom locator apps. Some of the most important tools aren't pills or gadgets, but strategies-such as controlling underlying conditions that can lead to incontinence (such as diabetes), weight loss, lifestyle or behavioral changes, and pelvic floor training.

Many devices that measure blood pressure without an inflatable arm cuff are in development, including a wristband recently cleared by the FDA for over-the-counter sale. It relies on a light-based sensor to detect changes in the amount of blood flowing through the vessels of the inner wrist, a technique known as photoplethysmography. But the devices have to be periodically calibrated, and as yet, there are no standards to validate the accuracy of cuffless devices.

Wearable fitness trackers like smart watches offer measurable and motivating data for exercise routines and safety, especially for people with heart conditions. Features include movement reminders, step counts (a daily total of 4,000 to 7,000 steps is considered beneficial), heart rate zones for exercise intensity, and measurements of heart rate recovery and variability to assess overall heart health. These tools can help optimize workouts and reveal potential issues.

Smart watches can monitor different parameters simply by measuring a person's pulse and body movements. Potentially helpful features include those to detect very low or high heart rates, irregular heart rhythms, and breathing disruptions during sleep.
