And since every health feature is designed to protect your privacy, you’re always in control of your data.
Heart health
Stay close to your heart.
Your heart beats over 100,000 times per day. Beat by beat, your heart rate and its response to activities like running or cycling are important indicators of your general health. With advanced features like high and low heart rate notifications, irregular rhythm notifications,1 the ECG app,2 and AFib History,3 Apple Watch gives you an invaluable view of your cardiovascular health.
Get heart health notifications.
Apple Watch uses the optical heart sensor and advanced algorithms to monitor your heart rate throughout the day and can alert you to unusually high, low, or irregular rhythms. You can also check your heart rate at any time with the Heart Rate app.
Take an ECG anytime, anywhere.
With Apple Watch you can check for signs of atrial fibrillation, or AFib — an irregular heart rhythm — by using the ECG app to generate a single-lead electrocardiogram. When you place your finger on the Digital Crown, built-in electrodes read and record the electrical heart signals straight from your fingertip and wrist. You can share a PDF of your ECG reading with your doctor.
AFib affects tens of millions of people around the world.
It’s estimated that AFib affects over 50 million adults worldwide, with a substantial increase in risk for those 65 years and older.4 If left untreated, it’s one of the leading conditions that can result in a stroke. You can help manage AFib with the right medications, regular exercise, and a heart-healthy diet.
Trace your AFib history.
If you’ve been diagnosed with atrial fibrillation, AFib History on Apple Watch can estimate how frequently your heart is in AFib. You can also view how lifestyle factors like exercise and sleep may influence the condition — and create a PDF of your AFib History to share with your care team.
Sleep
Sleep like a dream.
Sleep plays a crucial role in your physical and mental health, affecting everything from your immune system to your mood and more. Apple Watch helps you meet your sleep goals and can track your sleep. It can even identify signs of sleep apnea, which currently impacts more than one billion people worldwide.5
Meet your sleep goals.
Set up a sleep schedule in the Health app on iPhone and track your sleep with Apple Watch. Based on your designated bedtime, Apple Watch can give you wind-down reminders and automatically enable Sleep Focus, minimizing distractions across all your devices — from iPhone to Mac to Apple Watch.
Each sleep stage is essential.
The sensors in Apple Watch can tell you how much time you spend in the REM, Core, and Deep sleep stages, as well as when you might have woken up. REM is where you experience dreaming, and studies show it plays a key part in memory. During the Core phase, muscle activity decreases and your body temperature drops. Deep sleep has a restorative effect on the body. You can keep an eye on this data in the Sleep app.
Track your overnight health metrics.
The Vitals app on Apple Watch helps you spot changes in your health before you feel them.6 Quickly see your overnight health data right on your wrist — including sleep duration, heart rate, respiratory rate,7 and wrist temperature — and get notified if your metrics are ever outside your typical range.
Spot signs of sleep apnea.
Sleep apnea is a condition where breathing stops repeatedly and causes disrupted sleep. If untreated, it can lead to hypertension, type 2 diabetes, and cardiac issues. Apple Watch can reveal signs of sleep apnea by detecting small wrist movements that are associated with interruptions in normal respiratory patterns during sleep.8
Up to 80% of all sleep apnea cases go undiagnosed.9
Wearing your Apple Watch to bed is the first step to better understanding your risk.
Hearing
Tune in to your hearing health.
About 1.5 billion people around the world are living with hearing loss — and millions are unaware that they’re affected by it.10 To help you better understand your hearing and make caring for it more accessible, our medical and audio specialists worked together to develop an end-to-end hearing health experience for AirPods Pro 2.
Use a clinical-grade Hearing Aid feature with AirPods Pro 2.
You can access a Hearing Test and a Hearing Aid feature using just AirPods Pro 2 and an iPhone or iPad.11 After you complete the Hearing Test, if you have perceived mild to moderate hearing loss, your personalized hearing profile will guide you to the Hearing Aid feature. With a quick setup, you’ll start hearing more clearly immediately. You can even customize the settings to suit your needs.
Take a Hearing Test at home.
Find a quiet, comfortable place and launch the test from the AirPods Pro 2 settings on your iPhone or iPad. Pro-level Active Noise Cancellation and the in-ear seal help enable the conditions needed to conduct the evaluation. Once the test is completed, you’ll get easy-to-understand results and insights about your hearing.
150,000+ real-world audiograms and millions of simulations helped develop the Hearing Test.
Using pure-tone audiometry, the test — which is informed by learnings from the Apple Hearing Study — plays a series of tones that you respond to by tapping the screen of your iPhone or iPad. Helpful animations, tap-back effects, and progress indicators guide you through the experience, which takes about five minutes.
Help reduce your daily noise exposure.
One in three people are exposed to loud noise on a regular basis. AirPods Pro 2 provide active Hearing Protection across listening modes to help prevent exposure to loud environmental noise.12 The Noise app on Apple Watch can also alert you when sound levels in your environment could affect your hearing.
Fitness
Fuel your fitness.
Your personal fitness is the result of small lifestyle choices that add up every day. When you integrate positive habits — like regular activity and workouts — into your routine, it can help you to improve both your physical and mental health. From Activity rings to the Workout app, Apple Watch is in tune with all the ways you stay active — so motivation is always at arm’s reach.
Close your Activity rings.
Three rings: Move, Exercise, Stand. One goal: Close them every day. Apple Watch makes it easy to track your daily activity — inspiring you to move more, sit less, and get some exercise. You can adjust your goals for each day of the week or even put your rings on pause.
Set a daily Move goal.
Even if you don’t have an Apple Watch, you can set up a daily Move goal in the Fitness app on iPhone to keep yourself motivated. Track your steps, distance, and flights climbed, as well as workouts from third-party apps, to estimate the active calories that contribute to your Move goal.
Take your training further.
Apple Watch understands all the ways you work out. From running to yoga, it puts advanced metrics and views like Heart Rate Zones, training load, Power, and Elevation right on your wrist. And if you want to track how active you are over time, you can view your trends data in the Fitness app on your iPhone.
Cardio fitness insights can help you improve your long-term health.
Apple Watch can measure your cardiovascular health with VO2 max, which is the maximum amount of oxygen your body can consume during exercise. If your cardio fitness levels are low for your age and sex, you’ll receive a notification. You can improve your VO2 max by increasing the intensity and frequency of your cardiovascular exercise.
Your period is a vital indicator of your overall health. The Cycle Tracking experience on iPhone, Apple Watch, and iPad lets you log your period and record symptoms or cycle factors, so you have a deeper understanding of your menstrual cycle.13 Most recently, data from our ongoing Women’s Health Study — the first of its kind — has helped to improve Cycle Tracking predictions.
Stay in sync with your period.
Since cycles vary, the best way to understand what’s normal for you is by tracking your menstrual cycle. In the Health app on your iPhone, iPad, and Apple Watch, you can use Cycle Tracking to log your period, record symptoms, and get predictions about your next period or fertile window. It can also notify you if a cycle deviation is detected.
Get retrospective ovulation estimates.
Apple Watch has an advanced sensor that can track your temperature while you sleep.14 The Cycle Tracking app uses this data to provide a retrospective estimate of when you likely ovulated, which can be helpful for family planning. Wrist temperature can also be used to improve period predictions.
A pattern of cycle deviations can be a sign of an underlying health condition.
With Cycle Tracking you can receive a notification if your logged cycle history shows a possible deviation, such as irregular, infrequent, or prolonged periods and persistent spotting.
Get insights and notifications about your pregnancy.
In the Health app on iPhone or iPad, Cycle Tracking can provide you with additional support related to your health during pregnancy. For example, you can see your gestational age in Cycle Tracking, track your pregnancy across all your health charts, and be reminded to check in on your mental health more often — since during and after pregnancy you can be at a higher risk for conditions like depression.
Mental wellbeing
Be mindful of your mental health.
Your mental health is just as important as your physical health — in fact, they’re connected. Studies show that identifying your feelings can help you manage emotions and have a positive effect on the body by slowing your heart rate. Helpful features on iPhone, iPad, Apple Watch, and Apple Vision Pro let you reflect on your state of mind and build emotional awareness and resilience.
Monitor your state of mind.
With the Health app on iPhone and the Mindfulness app on Apple Watch, you can log your mood through simple, guided prompts. Interactive charts provide insights into your state of mind, how it changes over time, and what factors may influence it — such as exercise, sleep, and mindful minutes.
Take standardized mental health assessments.
You can also use the Health app to answer a set of clinically validated questionnaires about how you’re feeling, then see your current risk for depression or anxiety. This will help you understand whether you should talk to your doctor, and you’ll have a PDF of the results you can share.
Make mindfulness part of your day.
Center yourself with Reflect and Breathe sessions in the Mindfulness app on Apple Watch. Experience guided meditations with the Mindfulness app on Apple Vision Pro. And stay present with Apple Fitness+ Meditations in the Fitness app on iPhone, iPad, and Apple TV.15
Preserve memories, practice gratitude.
Journaling can help you reflect and practice gratitude, which has been shown to improve wellbeing. Whether you’re jotting down a memory or capturing a special moment, the Journal app on iPhone makes it easy to document your thoughts and observations through State of Mind, photos, videos, audio recordings, and more.
Vision
Look out for your vision.
Reading a book, watching a movie, capturing a powerful memory — for many of us vision is considered to be one of the most important senses, because it’s our main way of understanding and navigating our environment. iPhone, iPad, and Apple Watch offer features that help you care for your eyes.
Myopia, or nearsightedness, is the leading cause of vision impairment globally.16
Children between the ages of 5 and 15 are most at risk of developing myopia. It’s estimated to affect over 30 percent of the population currently and is expected to increase to 50 percent, or 5 billion people, by 2050.
Help prevent myopia in children.
One way to reduce the risk is by having your child spend at least 80 to 120 minutes outdoors in daylight each day.17 With Apple Watch For Your Kids,18 time in daylight can be measured on a child’s Apple Watch, even if they don’t have an iPhone.19 And with Health Sharing, parents can keep track of it.
How close is too close?
Viewing a device or book too closely for an extended period of time can increase the risk of myopia in children and eyestrain in adults. The Screen Distance feature on iPhone and iPad uses the same TrueDepth camera that powers Face ID to detect when you hold your device closer than 12 inches for an extended period and encourages you to move it farther away.20
Store your vision prescription in the Health app.
You can securely store your vision prescription in the Health app on your iPhone and iPad by simply taking a photo of the document and storing it. You also have the option to add the information from your prescription manually.
Apple Health app
A great view of you.
The Health app helps you organize your important health information — like medications, sleep, activity, and more — in one central and secure place that’s easy to access from your iPhone and iPad. It also provides interactive charts and advanced trend analysis, so you can track and view your health data over time.
All of our health features are built with privacy at the core and are designed to keep your data secure.
