When you think of wearable technology, you probably picture a wrist gadget: Apple Watches for health tracking, Fitbits for fitness goals, and the like.

But there is a whole universe of creative devices that transcend the conventional step counters and heart rate monitors, redefining health and fitness in unbelievable ways. And this is just the beginning—the market is estimated to more than double by 2029, reaching over $150 billion.

Such technology can assist in a wide range of areas, whether you’re looking to enhance a specific aspect of your well-being or tackle an exercise goal. Here are three key uses it provides along with the top tool for each one.

Aids sleep

Getting consistently good rest is one of the most important ways you can protect both your immediate and future health, and there are plenty of gadgets that can give you the data you need to make essential adjustments. The best of these may just be the Oura Ring, a small, sleek device you can wear on any finger for easy sleep tracking. It uses a mix of LED and other sensors to measure more than twenty biometrics, including your heart rate, skin temperature, and movement, then combines these data points into a single sleep score in the connected app to offer a holistic overview of your sleep quality.

Additionally, it’s able to detect when you are in light, deep, or REM sleep, providing analysis of how long you generally spend in each stage. It can even sense your blood oxygen levels to help you determine if you’re experiencing any disturbances in your breathing throughout the night—an important factor to assess given that thirty million Americans are thought to have sleep apnea, an issue that can have major long-term implications.

The Oura Ring is made of durable, water-resistant titanium and features a long battery life of up to seven days, allowing you to wear it virtually 24/7 without worry. And if you do, you can also use it for other activity tracking and health monitoring throughout the day. In essence, this device can help you cover most of your bases in a noninvasive and stylish way for around $300 to $350, depending on your preferred design. Note, however, that a subscription is required to access all its features; to avoid this, consider similar products like the Ultrahuman Ring AIR or the Samsung Galaxy Ring.

Improves posture

Correcting poor posture is crucial to preventing persistent back, neck, and shoulder pain, especially as more individuals spend hours seated at workstations or staring down at screens. If you’ve struggled to keep yourself from slouching in the past, you may want to invest in wearable tech crafted to help promote better habits. One such example is the UPRIGHT Go 2, a small gadget less than two inches big that sits on your upper back, just under your neck. Either attached via an adhesive strip or strung on a necklace, it can easily be hidden under your clothes so you can work on your posture without having to strap on a clumsy and noticeable brace.

The device functions by using built-in sensors that measure the angle of your spine and calibrate to your ideal positioning. From there, it will detect when you aren’t sitting, standing, or walking in said positioning and send vibrations to alert you to adjust appropriately. You can also set goals and assess your progress in the connected app. Over time, you’ll develop new muscle memory that will make maintaining proper posture second nature to benefit your spinal health.

This tool prices at $80, though if you’re looking for something a bit more economical, there are plenty of other options, such as those from Gear Elevation or TRAKK. Put it in place at the start of each day, and before long, you may just feel your back, neck, and shoulder pain melt away.

Tracks fitness

Whether your goal is to improve your figure or optimize your performance, wearable technology gives you access to all sorts of information you can use to better achieve it. But while wrist gadgets like smartwatches are most popular for tracking fitness and health data, there’s a newer wave of tech that goes beyond just counting steps or monitoring heart rate: smart clothing.

The primary innovator paving the way for this trend is Sensoria, a company that offers a range of fitness wear including smart socks, sports bras, and T-shirts. These garments use a combination of sensors, such as accelerometers and pressure sensors, to give you more accurate tracking of a variety of metrics. The socks, for instance, can measure your running cadence, impact force, and landing technique, which you can review in the associated app for real-time feedback. This will enable you to identify issues like imbalance and overuse so you can modify your form or get expert advice before an accident arises.

Depending on the type, Sensoria’s items range in price from $50 to $400, but the degree of detail you receive may be well worth the cost. Another brand to look at for more general health tracking is Hexoskin, which markets itself as the “most advanced smart clothing on earth & in space.”

In today’s digital age, wearable tech is quickly becoming one of the best tools for anyone wanting to maximize their health and fitness. So why not take the leap? Start investigating these innovative gadgets today, and discover what they can do for your well-being.
