Technology Is Changing How We Stay Healthy
From smartwatches that track your heart rhythm to virtual doctor visits from your couch, technology is putting more health information and care in your hands than ever before. These guides explain the tools available today, how to use them wisely, and what's coming next.
What Today's Wearables Can Track
Modern wearables can collect a surprising amount of health data. Some features are cleared by the FDA for specific medical uses, while others are meant for general wellness, so it's worth knowing the difference.
Heart Rate
Resting and active trends
ECG
Can flag signs of atrial fibrillation
Sleep
Duration and estimated stages
Activity
Steps, workouts, calories
Blood Oxygen
Estimated SpO2 levels
Glucose
Continuous glucose monitors
Fall Detection
Can alert emergency contacts
Temperature
Skin temperature shifts
Wearable data is great for spotting trends over time, but readings can be less accurate than medical-grade equipment. Treat alerts as a reason to check in with your doctor, not as a diagnosis.
Is Telehealth Right for Your Visit?
Virtual visits save time and travel and make it easier to get care quickly. They work well for many needs, but some situations still call for an in-person exam.

- Colds, allergies, and minor rashes
- Prescription refills and medication check-ins
- Follow-ups and reviewing test results
- Mental health counseling and therapy

✗ Go In Person or Call 911
- Chest pain or trouble breathing
- Signs of stroke like face drooping or slurred speech
- Serious injuries, deep cuts, or possible broken bones
- Severe abdominal pain
- Anything that needs a hands-on exam, lab work, or imaging
How AI Is Being Used in Healthcare
Artificial intelligence is already working behind the scenes in many hospitals and clinics. It's designed to support doctors, not replace them.
Protect Your Health Data
Many consumer health apps and devices aren't covered by HIPAA, the federal law that protects information held by doctors and insurers. That means your data could be shared or sold depending on the company's policies.
- Read the privacy policy before signing up
- Check what data is shared with third parties or advertisers
- Turn off permissions an app doesn't need, like location or contacts
- Use strong passwords and two-factor authentication
- Keep apps and devices updated
- Delete your account and data when you stop using an app
Tips for Choosing a Health App
Check the source
Look for apps made or reviewed by hospitals, universities, or medical experts.
Ask your doctor
Many providers recommend specific apps and can review your data with you.
Be wary of big claims
Apps that promise to diagnose or cure conditions deserve extra skepticism.
Keep it simple
The best app is one you'll actually use. Start with one goal and one tool.
