You're walking through your day, effortlessly monitoring your health, steps, and heart rate without the bulk of a fitness watch on your wrist. Rather, a sleek smart ring lies unnoticed on your finger, working its magic quietly in the background. Interested? You're not the only one. With all the hype over these little tech wonders, people are wondering if they're actually as accurate as their clunky cousins—the fitness watch.

Smart rings are a trendy, minimalist version of the old-style fitness watch and have been widely adopted by health tech buffs, athletes, and even medical practitioners. They come in sleek form, being undistinguishable as jewelry, loaded with strong sensors that can measure sleep, heart rate, and a multitude of wellness indicators. But at what price: reduced accuracy because they are so small? And most importantly, can they really compete with—or even outdo—smartwatches in health monitoring?

The answer is not so simple. Smart rings might be less capable in some respects, but recent studies and developments indicate that they have promising strengths, particularly in the accuracy of some health measurements. Here's an in-depth, exclusive comparison of how smart rings compare to fitness watches.

Smart Rings vs. Smartwatches

At the core of both smart rings and smartwatches lies the same foundational technology—photoplethysmography (PPG). This method uses light-based sensors to measure changes in blood volume, providing real-time data on your heart rate. However, where the device is worn makes a significant difference.

According to a 2022 review in Frontiers in Physiology, the finger is a more vascular-rich area compared to the wrist. That is, smart rings might provide more accurate readings, particularly for heart rate tracking, due to the proximity of the finger to rich blood vessels. Also, a study published in 2023 in Mayo Clinic Proceedings: Digital Health pointed out that smart rings might provide more accurate readings of heart rates in individuals with darker skin. The palm contains less melanin than the wrist, minimizing the light distortion that PPG sensors tend to have trouble with.

However, they have their prerequisites. Motion artefacts—motion-induced interference—can warp smart ring readings, particularly during exercise. According to a 2021 study in the Journal of Electrical Bioimpedance, even minimal movement of the finger during light exercise can invalidate ring-based sensor accuracy. And not like smartwatches, smart rings generally have no onboard GPS and sophisticated accelerometers, thus restricting their use in monitoring challenging workouts or runs.

Even with some immediate limitations, smart rings are rapidly advancing. New prototypes indicate that these wearables may soon far surpass heart rate and sleep tracking. One exciting advance is the result of a January 2024 paper published in IEEE Transactions on Mobile Computing, which introduced a smart ring to track hand hygiene in real time—a revolution in healthcare environments. The ring's electrochemical fluid sensor proved to be 97.8% accurate, more than a 10% improvement over available electronic hygiene monitors.

Another 2021 Computer Modeling in Engineering & Sciences study presented a ring that would be able to sense early hand tremors, an early sign of Parkinson's disease. As research advances, experts envision future rings will even track blood glucose, hydration, and blood pressure—marking the beginning of a new era of passive, ongoing health monitoring.

Sleep Tracking and Wellbeing

When it comes to sleep monitoring, smart rings really shine. Their light, non-intrusive nature makes them perfect for wearing overnight. Unlike smartwatches—which are often found to be cumbersome in bed—smart rings can easily track your sleep without disturbing you.

Brands take it a step further, providing detailed information on energy levels, sleep phases, recovery, and even the best time to consume caffeine. Although a 2024 meta-analysis in Applied Sciences noted that smart rings tend to underestimate REM sleep, they still provide a holistic picture of sleep patterns by integrating data points such as heart rate variability, respiratory rate, and skin temperature.

Nevertheless, experts warn that such rings should be employed to identify trends, not to diagnose sleep disorders. "Smart rings can help identify trends, but they can never replace a sleep study that monitors brain activity," said wearable tech researcher Semitha.

Comfort, Design, and User Preference

Comfort and style are huge pluses for smart rings. They are less obtrusive and better-looking than clunky wrist-mounted devices, making them easier to incorporate into daily wear. But all is not great in the design world. Even with their streamlined marketing, many rings look clunky on smaller hands, and matte finishes tend to wear off after a while with regular use.

Smartwatches, in contrast, have adjustable sizes and removable straps, which may be attractive to those looking for flexibility. Premium smartwatches are more likely to be stronger, since they are manufactured from superior materials and designed to endure intense use.

Which One Is Best for You?

Ultimately, deciding between a smart ring and a smartwatch comes down to your individual health objectives, way of life, and personal comfort level.

If you're a fitness buff requiring precise workout tracking, GPS, and exercise recognition, a smartwatch is still the better choice.

If you're more concerned with sleep quality, daily readiness, recovery, and overall wellness—and don't mind something less invasive—a smart ring could be a game-changer.

For those who value medical-grade accuracy, both devices still lag behind clinical equipment, but smart rings potentially have more future potential because they are closer to high-fidelity data points.

Significantly, neither device is 100% accurate, but both can give you useful insights that enable you to make healthier lifestyle choices.

Smart rings are more than a fad. They are a new convergence of design, health, and technology that will have significant potential to become powerful weapons in personalized healthcare. As technology continues to improve in sensors, the distinction between wearables and medical devices might get blurred, and users could become empowered to take proactive actions towards their healthcare.

In the meantime, these rings can be thought of as hot trend friends to your health journey—not as alternatives to professional health care, but as virtual cues toward improved behaviors.

As the health tech landscape continues to evolve, the finger may just become the most important real estate in wearable innovation. And with every ring that tracks your sleep or your heart rate, we're one step closer to a future where wellness is literally at your fingertips.

Cortisol is one of the body's most powerful hormones, which is essential for survival, yet capable of quietly undermining health when chronically elevated. The line between beneficial training stress and harmful overload is thinner than most athletes realize, and the body's early warning signals are easy to dismiss.

Understanding how cortisol responds to exercise and when that response tips from adaptive to destructive is foundational to training smarter, recovering better, and protecting long-term health.

Why Cortisol Matters

Cortisol is a vital, life-sustaining hormone essential for survival and adaptation. During physical exertion, it ensures the immediate mobilization of energy by triggering the breakdown of stored carbohydrates and fats (gluconeogenesis and lipolysis) to fuel working muscles. Additionally, it maintains vascular integrity and acts as a powerful anti-inflammatory agent, safely modulating the immune system to protect the body against extreme inflammation caused by exercise-induced tissue damage.

When Exercise Becomes Stress

Exercise is naturally an acute stressor, but it transitions into a harmful chronic stress when training loads exceed the body's ability to recover. High-intensity, prolonged aerobic exercise or extreme high-volume resistance training, combined with inadequate rest, sleep disruption, and external stressors, keeps the hypothalamic-pituitary-adrenal (HPA) axis constantly activated. When the natural 24-hour cycle of cortisol is disrupted and if the body does not get a long enough period of low cortisol exposure, exercise transitions from a positive adaptation (eustress) into destructive physiological strain.

Beyond Stress: How Excess Cortisol Reshapes the Body

The physical remodeling that chronic cortisol causes is profound and operates at the molecular level. Protein degradation occurs through activation of the ubiquitin–proteasome system. Cortisol further suppresses anabolic pathways by inhibiting mTOR signaling and reducing insulin-like growth factor 1 activity, leading to a sustained decrease in protein synthesis.

Visceral fat cells, the deep abdominal fat surrounding internal organs, have more cortisol receptors than fat cells elsewhere in the body. When cortisol levels remain elevated, these receptors essentially attract and store more fat in the midsection.

While Ozempic or Wegovy offer weight loss benefits, a significant caveat is the risk of regaining the kilos. This is not only a waste of money and effort but may also affect overall health.

About 70 per cent of people who stop these drugs eventually regain much of the weight they lost, often within 18 months.

Now, US researchers have developed a new minimally invasive procedure that resets the gut, and in early trials, has shown potential to help people maintain weight loss after stopping these popular drugs, which contain semaglutide — a GLP-1 receptor agonist — as the main ingredient.

Presenting the research at the Digestive Disease Week (DDW) 2026, the team noted that the procedure works by renewing the lining of the upper small intestine. It potentially “resets” metabolism and helps preserve the benefits of weight loss.

The technique is called duodenal mucosal resurfacing. In a clinical trial, people who underwent the procedure regained far less weight compared to others after discontinuing the medication.

"Finding a treatment that allows patients to stop these medications without weight regain or loss of metabolic benefit is a huge unmet need," said lead author Shelby Sullivan, director of the Endoscopic Bariatric and Metabolic Program at Dartmouth Health Weight Center and professor of medicine.

"These findings indicate that this minimally invasive procedure may provide lasting weight-loss maintenance."

How The Procedure Works

Duodenal mucosal resurfacing is an investigational endoscopic treatment that uses controlled heat to remove damaged tissue from the inner lining of the duodenum, the first section of the small intestine just below the stomach.

This process, which ablates the unhealthy mucosal layer, encourages the growth of new, healthier tissue.

The treatment targets the small intestine, where many of the hormones affected by GLP-1 drugs are produced. Over time, diets high in fat and sugar can alter the lining of the duodenum, changing how the body processes food and regulates hormones. These changes can contribute to insulin resistance and metabolic disease.

By restoring a healthier mucosal layer, the procedure aims to reset the body's response to food, helping to stabilize metabolism at a lower body weight after stopping medications like Ozempic.

How Was The Study Conducted?

The findings are based on an early group of participants with six months of follow-up data. Among 45 people in this cohort, 29 received the resurfacing treatment while 16 underwent a sham procedure.

All participants had previously lost at least 15 per cent of their body weight using tirzepatide before stopping the drug. On average, patients lost about 40 pounds while on GLP-1 therapy. Six months after discontinuing the medication, those in the control group regained significantly more weight. Participants who received the sham procedure regained about 40 per cent more weight than those who underwent the actual treatment.

In addition, patients who had more extensive resurfacing regained only about 7 pounds and kept more than 80 per cent of their weight loss.

By comparison, the control group regained roughly twice as much. The gap between the two groups continued to widen from one to six months after the procedure, suggesting the benefits may persist and even strengthen over time.

"What's particularly encouraging is that the benefit appears to increase over time rather than fade, and that it behaves like a drug in terms of dose response," Dr. Sullivan said. "That gives us confidence that we're targeting the right biology."

No serious complications were reported from either the device or the procedure. Recovery is relatively quick, with most patients returning to normal activities within about a day.

At a time when most people follow a sedentary lifestyle, exercise is nothing short of medicine. However, for someone who is lazy, workouts can take a good deal of effort — but what if we told you that there are some simple exercises that will not take much of your time and can be done easily while lying flat on your back? According to experts, without having to lift a finger, you can get in shape.

Best workouts to do in bed

Researchers at Teikyo University in Tokyo, Japan, found that people can improve their agility, balance, and flexibility by engaging in a simple exercise programme that involves three exercises. These exercises engage the leg muscles and core in an easy and safe position. Writing in the journal PLOS One, the study authors compared the routine to Pilates, and experts said that it can help prevent falls and support early rehabilitation.

Adults are recommended to do two and a half hours of exercise each week, but about a third of people do not meet this target. In this study, 39 healthy men and women in their 20s, with optimal flexibility, balance, speed, and strength, were involved. They were all tested before and after a two-week regimen of lying down and working out. The exercises they were asked to perform were:

1. Tense the abs for five seconds while pressing them with the fingers—repeat three times
2. Lifting the hips off the ground to form a bridge pose, keeping the feet flat on the ground—hold for five seconds and repeat 10 times
3. Bending one leg at the knee and holding the ankle at 90 degrees, clenching and unclenching the toes; ensure that the heel slides along the floor towards and away from the body—repeat three times with each leg

Fifteen days later, participants showed significant improvement in standing balance, flexibility, and agility. However, they did not show improvement in raw muscle strength, jumping ability, or grip strength tests. Scientists said that these improvements were likely due to better muscle control rather than increased muscle mass. They also noted that no prior research has shown an exercise programme that is short and performed in a supine position to be effective in this way. However, this routine, which showed improvements in flexibility, agility, balance, and stability, shows promise. It could also be helpful for rehabilitation in older adults.

What is exercise snacking?

Exercise snacking refers to an approach created for people who struggle to find time for long gym sessions. Instead of spending hours at the gym, people can perform small bursts of exercise throughout the day. These sessions are an effective way to stay active without needing to block out time specifically for fitness. They can be spread across the day, with mini workouts lasting five to 10 minutes and repeated multiple times. The benefits are significant when practised consistently, especially for those with desk jobs or those suffering from diabetes, hypertension, high cholesterol, or even depression.
