We’re All Stressed, and Your Next Wearable Will Know It

Your wellbeing was a big focus at CES. Companies showed off smartwatches and fitness bands aimed at tracking your mental health.

Wearables can already track a dizzying number of bodily statistics, from heart rate to blood oxygen levels and skin temperature. If the new devices shown at CES 2023 are any indication, the next wave of smartwatches and wristbands aim to gain a better understanding of your alertness, fatigue and stress levels, too.

Watchmaker Citizen and smaller brands like BHeart and Nowatch have all announced new wearables that claim to pay close attention to your mental wellbeing. The shift toward stress tracking isn’t necessarily new, as I wrote in September when covering Fitbit’s Sense 2 and the Happy Ring. But the announcements at CES suggest that tech companies are interested in monitoring other factors that play into mental wellness.

The launches come as stress has been on the rise in the US because of factors like political divisiveness and inflation in addition to the pandemic, according to a survey conducted by the Harris Poll on behalf of the American Psychological Association.

«Modern life was hard enough with constant technology and ever-present communication and the pace of life,» Dr. Debra Kissen, CEO of the Light On Anxiety Treatment Center, which specializes in cognitive behavioral therapy services, previously said to CNET. «And then throw in a pandemic, and I think it really brought mental health concerns that were always there undeniably to the surface.»

This recent interest in exploring the link between physical and mental wellness also comes as annual smartwatch upgrades aren’t as pivotal as they used to be. Now that smartwatches have matured and the problems that plagued early devices have been addressed, companies large and small are searching for what’s next.

Citizen says its CZ Smart watch can gauge alertness and fatigue

Citizen says its new CZ Smart watch uses tools built based on research from the NASA Ames Research Center Fatigue Countermeasures Laboratory to assess fatigue and alertness levels. One of the biggest features that separates it from other wearables is its Alert Score, which it generates after you take the Alert Monitor test in Citizen’s YouQ wellness app. That test is based on the Psychomotor Vigilance Test that NASA has used to assess astronauts’ alertness.

The watch also wants to help you understand whether you’re a morning or evening person by analyzing your sleep patterns and Alert Scores. The overall goal is to combine these readings with more traditional metrics like heart rate and activity to make suggestions about how to address fatigue and increase your alertness. The «casual» finish starts at $350 (roughly 290, AU$520), while the «sport» edition starts at $375.

The BHeart band is a stress tracker you can attach to a regular watch

Health tech company Baracoda’s BHeart band grabbed headlines for its self-charging design that the company claims uses motion, body heat and sunlight to power itself. But the wristband is also another example of a new wearable attempting to provide mental health insights in addition to tracking physical metrics.

It claims to calculate stress management readings using heart rate variability. The app may suggest that users take a walk or do some yoga to relax based on those readings. Since it’s a watch band and not an actual watch, you can also wear the BHeart strap with any standard watch that has a lug width of 18 to 22 centimeters. The band starts at $100 and launches in April.

The Nowatch claims to estimate stress and cognitive performance

If you couldn’t tell from the name alone, the Nowatch isn’t a watch. It’s a screenless wellness tracker that claims to measure stress and cognitive performance.

The company worked with Philips on sensors that can measure electrodermal activity — or changes in sweat — to estimate stress levels. Fitbit uses similar technology in its Sense and Sense 2 devices. Users can also press the crown on their watch to mark specific stressful moments so that the watch can log it within the app. That sounds a bit different than Fitbit’s approach with the Sense 2, which can automatically flag potential signs of stress in addition to performing on-demand stress readings.

But one of the Nowatch’s more unique offerings is its Predicted Cognitive Zone feature, which the company says can provide insight on the wearer’s cognitive performance based on their physical state.

The Nowatch starts at $499, although the company is temporarily selling it for $369 until Jan. 9.

The next step for wearables

It took years for smartwatches, smart rings and fitness bands to turn sleep and activity data into meaningful insights that actually feel useful. Now, companies are seemingly setting their sights on addressing other factors that impact our health like stress, burnout and lack of sleep.

In addition to the new devices at CES, Fitbit debuted the second generation of its Sense smartwatch last fall — which doubles down on the stress tracking tech it introduced in the first model. Polar also announced the Ignite 3 watch in November, which claims to pinpoint the time of day in which you’ll be most alert based on your sleep cycles. Biogen announced in 2021 that it was collaborating with Apple on a research study to investigate the role that the Apple Watch and iPhone could play in monitoring cognitive performance.

Of course, it’s important to remember that these are just claims for now. It’s impossible to know whether these tools are accurate or useful without using them. The devices also arrive at a time when there’s increased awareness and scrutiny over the amount of data that tech devices gather about their users.

Dr. Charles A. Odonkor, assistant professor at the Yale University School of Medicine, also previously told CNET that changes in bodily markers like heart rate, perspiration and blood pressure may not always indicate stress and could be a sign of other conditions.

Still, the arrival of devices like these suggest that the next frontier for wearables could be about much more than just motivating you to hit the gym.

Get Ready for a Striking Aurora That Could Also Disrupt Radio Communications

Don’t expect the storm to cause a lingering problem, though.

A geomagnetic storm is threatening radio communications Monday night, but that doesn’t mean you should be concerned. In fact, it may be an opportunity to see a colorful aurora in the night sky.

The National Oceanic and Atmospheric Administration has issued a geomagnetic storm watch after witnessing a coronal mass ejection from the sun on Saturday. The watch, which was issued over the weekend and will expire after Monday, said the onset of the storm passing over Earth on Sunday night represented a «moderate» threat to communications. As the storm continues to pass through, it could deliver a «strong» threat on Monday night that could cause radio communications to be temporarily disrupted during the worst of it.

Even so, NOAA said, «the general public should not be concerned.»

A coronal mass ejection occurs when magnetic field and plasma mass are violently expelled from the sun’s corona, or the outermost portion of the sun’s atmosphere. In the vast majority of cases, the ejection occurs with no real threat to Earth. However, in the event the ejection happens in the planet’s direction, a geomagnetic storm occurs, and the Earth’s magnetic field is temporarily affected.

In most cases, geomagnetic storms cause little to no disruption on Earth, with radio communications and satellites affected most often. In extreme cases, a geomagnetic storm can cause significant and potentially life-threatening power outages — a prospect that, luckily, the planet hasn’t faced.

Switching poles

Every 11 years, the sun’s magnetic poles switch, with the north pole and south pole swapping positions. During those cycles, the sun’s activity ramps up as it gets closer to pole-switching time. The height of its activity is called solar maximum, and scientists believe we either may be entering the solar maximum or may be already in it.

During periods of heightened solar activity, sunspots increase on the sun and there’s an increase in coronal mass ejections, among other phenomena. According to NOAA, solar maximum could extend into October of this year before the sun’s activity calms and it works towards its less-active phase, solar minimum.

Even when geomagnetic storms hit Earth and disrupt communications, the effects are usually short-lived. Those most affected, including power grid operators and pilots and air traffic controllers communicating over long distances, have fail-safe technologies and backup communications to ensure operational continuity.

But geomagnetic storms aren’t only about radios. In most cases, they also present unique opportunities to see auroras in the night sky. When the storms hit, the plasma they carry creates a jaw-dropping aurora, illuminating the night sky with brilliant colors. Those auroras can be especially pronounced during the most intense phases of the storm, making for nice stargazing.

If you’re interested in seeing the aurora, you’ll need to be ready. The NOAA said the «brunt of the storm has passed» and even if it lingers into Tuesday, there won’t be much to see after Monday night.

Last Total Solar Eclipse for 20 Years Is Coming: How to See and Photograph It

It’s your last chance until 2044.

Get your eclipse glasses ready, Skygazers: the Great American Eclipse is on its way. On April 8, there’ll be a total eclipse over North America, the last one until 2044.

A total solar eclipse happens when the moon passes between the Earth and the sun, blocking the sun and turning an otherwise sunny day to darkness for a short period of time. Depending on the angle at which you’re viewing the eclipse, you may see the sun completely shrouded by the moon (called totality) or some variation of it. The more off-angle you are and the further you are from the path of the eclipse, the less likely you’ll be to see the totality.

The 2024 total solar eclipse will happen on Monday, April 8. The Great American Eclipse will reach the Mexican Pacific coast at 11:07 a.m. PT (2:07 p.m. ET), and then traverse the US in a northeasterly direction from Texas to Maine, and on into easternmost Canada. If you want a good look at it, but don’t live in the path of totality, you shouldn’t wait much longer to book accommodation and travel to a spot on the path.

Or how about booking a seat in the sky? Delta Airlines made headlines for offering a flight that allows you to see the entire path of totality. Its first eclipse flight, from Austin, Texas, to Detroit sold out quickly. But as of Monday, Delta has added a second flight from Dallas to Detroit, which also covers the path of totality. The airline also has five flights that will offer prime eclipse viewing.

Not everyone can get on one of those elusive eclipse-viewing flights. Here’s a look at other options to nab a chance to see this rare sight and what to know about it.

Total solar eclipse path

The eclipse will cross over the Pacific coast of Mexico and head northeast over mainland Mexico. The eclipse will then make its way over San Antonio at approximately 2:30 p.m. ET on April 8 and move through Texas, over the southeastern part of Oklahoma and northern Arkansas by 2:50 p.m. ET.

By 3 p.m. ET, the eclipse will be over southern Illinois, and just 5 minutes later, will be traveling over Indianapolis. Folks in northwestern Ohio will be treated to the eclipse by 3:15 p.m. ET, and it will then travel over Lake Erie and Buffalo, New York, by 3:20 p.m. ET. Over the next 10 minutes, the eclipse will be seen over northern New York state, then over Vermont. By 3:35 p.m. ET, the eclipse will work its way into Canada and off the Eastern coast of North America.

Best places to watch the Great American Eclipse

When evaluating the best places to watch this year’s total eclipse, you’ll first want to determine where you’ll have the best angle to see the totality. The farther off-angle you are — in other words, the farther north or south of the eclipse’s path — the less of an impact you can expect.

Therefore, if you want to have the best chance of experiencing the eclipse, you’ll want to be in its path. As of this writing, most of the cities in the eclipse’s path have some hotel availability, but recent reports have suggested that rooms are booking up. And as more rooms are booked, prices are going up.

So if you want to be in the eclipse’s path, and need a hotel to do it, move fast. And Delta’s eclipse-viewing flight from Dallas to Detroit has just four seats left at the time of publication.

Eclipse eye safety and photography

As with any solar eclipse, it’s critical you keep eye safety in mind.

During the eclipse, and especially during the periods before and after totality, don’t look directly at the sun without special eye protection. Also, be sure not to look at the sun through a camera (including the camera on your phone), binoculars, a telescope or any other viewing device. This could cause serious eye injury. Sunglasses aren’t enough to protect your eyes from damage.

If you want to view the eclipse, you’ll instead need solar viewing glasses that comply with the ISO 12312-2 safety standard. Anything that doesn’t meet that standard or greater won’t be dark enough to protect your eyes. Want to get them for free? If you’ve got a Warby Parker eyeglasses store nearby, the company is giving away free, ISO-certified solar eclipse glasses at all of its stores from April 1 until the eclipse, while supplies last.

If you don’t have eclipse viewing glasses handy, you can instead use indirect methods for viewing the eclipse, like a pinhole projector.

In the event you want to take pictures of the eclipse, attach a certified solar filter to your camera. Doing so will protect your eyes and allow you to take photos while you view the eclipse through your lens.

There’s also a new app to help you both protect your eyes and take better photos of the eclipse on your phone. Solar Snap, designed by a former Hubble Space Telescope astronomer, comes with a Solar Snap camera filter that attaches to the back of an iPhone or Android phone, along with solar eclipse glasses for protecting your eyesight during the event. After you attach the filter to your phone, you can use the free Solar Snap Eclipse app to zoom in on the eclipse, adjust exposure and other camera settings, and ultimately take better shots of the eclipse.

2024 eclipse compared to 2017

The last total solar eclipse occurred in 2017, and many Americans had a great view. Although there are plenty of similarities between the 2017 total solar eclipse and the one coming April 8, there are a handful of differences. Mainly, the 2024 eclipse is going to cover more land and last longer.

The 2017 eclipse started over the northwest US and moved southeast. Additionally, that eclipse’s path was up to 71 miles wide, compared with a maximum width of 122 miles for this year’s eclipse. Perhaps most importantly, the moon completely covered the sun for just 2 minutes, 40 seconds in 2017. This year, maximum totality will last for nearly four-and-a-half minutes.
