Wellness technologies are becoming a familiar part of many people’s routines, from gyms to home setups. As interest grows, so does the research examining how these tools interact with the body and what they may offer. This article provides an overview of commonly used technologies and summarises current findings without making claims or recommendations.  

Infrared Saunas

Infrared saunas use infrared light to warm the body directly. They are often chosen for relaxation, comfort, and post-exercise routines. Research in this area has looked at cardiovascular responses, circulation, perceived muscle soreness, and general well-being during and after sauna use. Some studies report changes in heart rate and sweating patterns that differ from traditional saunas, while others focus on subjective reports such as feeling more relaxed. Results vary depending on the temperature used, the length of sessions, and individual health factors. Because study designs differ, the outcomes are not always consistent, but infrared saunas remain a topic of ongoing research as scientists explore how heat exposure influences the body.  

Red light therapy (photobiomodulation)

Red light therapy uses low-level red or near-infrared wavelengths and is often used for skin and hair related purposes. Research shows the strongest evidence so far relates to supporting hair growth and some cosmetic skin effects, such as changes in collagen production and local blood flow. Other suggested uses have mixed or limited data, and results can vary depending on the wavelength, device strength and how consistently it’s applied. Studies also note that many claims circulating online go beyond what current evidence supports. At-home devices tend to be less powerful than those used in clinical environments, and outcomes are not guaranteed. As with any skin or wellness practice, it can be helpful to speak with a qualified professional before relying on red light therapy for specific concerns.  

Cold Exposure and Ice Baths

Cold immersion is commonly included in athletic and recovery practices. People use ice baths for a range of reasons, including post-exercise routines or to support a sense of alertness. Research has focused on perceived muscle soreness, inflammation markers, and short-term recovery after strenuous activity. Several studies suggest that cold exposure may reduce the perception of soreness in the hours following intense exercise. Other research has explored effects on mood and mental resilience. The variability in water temperature, timing, and duration across studies makes it difficult to draw universal conclusions, but cold exposure remains a widely researched area.  

PEMF (pulsed electromagnetic field) technology

PEMF devices use low-frequency electromagnetic fields and are often explored for general wellness and recovery routines. Research reviews show that PEMF has been studied for a wide range of biological responses, including circulation, cellular activity, bone-related processes and sleep quality. A large scientific review highlights that PEMF research spans many different study designs, frequencies and device types, which is why results can vary and are sometimes difficult to compare. Current evidence shows interest in how PEMF may influence cellular signalling, tissue recovery, and sleep-related outcomes, but there is no single agreed-upon protocol and outcomes depend heavily on the specific device settings used. Overall, PEMF remains an active area of research, with scientists continuing to investigate how electromagnetic fields interact with biological tissues.  

Oxygen-related wellness modalities (mild hyperbaric oxygen)

Mild hyperbaric oxygen involves slightly increased atmospheric pressure combined with a modest rise in oxygen concentration. Research shows this can increase the amount of dissolved oxygen in the blood, which may support general oxidative processes in the body. Studies also note that mild exposure, when carefully controlled, appears to avoid some of the risks associated with higher-pressure medical hyperbaric treatments. Outcomes vary depending on the exact pressure, oxygen level and duration used, and there is still ongoing research to understand how these gentle shifts in oxygen availability may influence overall physiology and well-being.  

Mindfulness and meditation technologies

Digital tools that support mindfulness and meditation have become widely used. Research consistently shows associations between mindfulness practices and improved stress management, emotional regulation and cognitive function. According to a 2024 systematic review, mindfulness may influence brain networks involved in attention, self-awareness and emotional processing. The review also discusses potential changes related to neuroplasticity, suggesting that regular practice may support long-term adaptability in the brain. While responses vary by individual and practice frequency, mindfulness remains one of the most well-studied approaches in the wellness space.  

Sleep-tracking technology

Sleep trackers are widely used to monitor habits such as sleep duration, bedtime patterns and nightly movement. Research shows that consumer devices can provide reasonably good estimates of total sleep time and general sleep–wake patterns, making them useful for spotting trends over days or weeks. According to one review, most sleep trackers rely on movement sensors or heart-rate–based algorithms, which means their data can be helpful for observing routines but is not as precise as clinical sleep assessments. The review notes that trackers are best suited for giving users a broad picture of how consistently they sleep, rather than identifying specific disorders or accurately distinguishing between sleep stages. Even so, many people find these devices helpful for understanding how factors like screen use, stress, activity levels or bedtime timing influence their overall sleep patterns. Their main value lies in long-term tracking and habit awareness, rather than diagnosis or medical interpretation.  

Understanding the Research

Across all wellness technologies, research is growing but not definitive. Many studies involve small participant groups, specific protocols, or short timeframes, which limits how widely the results can be applied. Wellness experiences are also highly individual, meaning people may respond differently based on factors such as fitness level, health history, lifestyle, and personal preference. What these technologies do offer is an expanding field of study. Researchers continue to investigate how light, heat, cold, electromagnetic fields, oxygen, and mindfulness practices interact with the body and mind. This creates a clearer picture of how these tools function and where they may contribute within broader wellness routines.  

A Helpful Reminder

Everyone’s health needs are different. If you’re considering adding new wellness practices to your routine, it can be useful to speak with a qualified health professional, particularly if you have existing questions or health considerations.
