(Press-News.org) DARIEN, IL – Wearing a phototherapy device that emits near-infrared light is associated with potential therapeutic benefits for sleep and daytime functioning, according to a new study to be presented at the SLEEP 2023 annual meeting.
Results show that self-reported, sleep-related symptoms improved after three weeks of treatment. Participants in the active treatment group reported experiencing better sleep quality, feeling more refreshed and relaxed, and functioning better during the day.
“This novel phototherapy device — while still being explored and in need of further research — appeared to be generally well-tolerated by a small group of participants,” said lead author Kathryn Kennedy, a doctoral candidate in the department of psychiatry at the University of Arizona in Tucson. “Those with active, light-emitting devices — as opposed to the inert sham devices — self-reported an increase in relaxation and better sleep with use.”
According to the authors, transdermal delivery of near-infrared light exhibits several therapeutic properties, including increased relaxation, likely through stimulation of parasympathetic activity. However, the benefits of near-infrared light delivery for sleep and next-day daytime functioning have been unexplored.
The five-week, randomized, sham-controlled study involved 30 adults between the ages of 30 and 60 years. Each participant reported having sleep complaints but did not have a sleep disorder. After a two-week baseline period, participants wore a cervical collar every other night before bed for three weeks. For those in the active treatment group, the collar emitted near-infrared light, and for those in the sham treatment group, the collar was inactive. Participants completed questionnaires about physical symptoms and insomnia severity, and they provided daily ratings of measures such as sleep quality, perceived changes to sleep, feeling refreshed, relaxation, and daytime functioning. Results were compared between groups.
Kennedy noted that while there are many sleep trackers in the marketplace, there are few wearable devices targeted at improving sleep and next-day performance, making near-infrared light an intriguing candidate with potential to become a novel treatment for sub-clinical sleep complaints.
“Given the emerging field of photobiomodulation and its potential neuroprotective and vasodilating effects, this red-light and near-infrared emitting device may be useful if milliwatt power level, dosage, and frequency of use are refined,” she said.
The research abstract was published recently in an online supplement of the journal Sleep and will be presented Tuesday, June 6, during SLEEP 2023 in Indianapolis. SLEEP is the annual meeting of the Associated Professional Sleep Societies, a joint venture of the American Academy of Sleep Medicine and the Sleep Research Society.

UC Irvine-led interdisciplinary team delves into a heated debate about humidity
2023-05-31
Irvine, Calif., May 31, 2023 – As climate change increases the severity, frequency and duration of heat waves around the world, researchers at the University of California, Irvine and other institutions are sounding an alarm about what they consider to be an added threat to human health: humidity.
Heat extremes increase the risk of illness and death, with the worst outcomes among people who are older, have chronic diseases, live in hot climates and are socioeconomically disadvantaged. In addition, humidity causes heat stress by making it harder for bodies to cool, but medical and public health experts still disagree about ...
Level of support for gender-neutral option on state IDs affected by political orientation, social context
2023-05-31
Key takeaways
As of June, 22 U.S. states and the District of Columbia will offer the opportunity for residents to select a gender-neutral marker on government-issued IDs.
UCLA sociologist Abigail Saguy found that LGBTQ+ and feminist activists support both the addition of a gender-neutral option and the removal of gender identifiers on IDs.
Conservative activists oppose both measures.
As of June, 22 states and the District of Columbia will allow residents to select a gender-neutral “X” marker, rather than “male” or “female,” on their driver’s licenses, ...
NIH scientists find treatment for rare genetic skin disorder
2023-05-31
Researchers at the National Institutes of Health and their colleagues have identified genomic variants that cause a rare and severe inflammatory skin disorder, known as disabling pansclerotic morphea, and have found a potential treatment. Scientists discovered that people with the disorder have an overactive version of a protein called STAT4, which regulates inflammation and wound healing. The work also identified a drug that targets an important feedback loop controlled by the STAT4 protein and significantly improves symptoms in these patients. The results were ...

When countries cut taxes for new ideas, capital investments rise
2023-05-31
AUSTIN, Texas — Corporate tax breaks for innovation lead to two kinds of economic growth: in capital investment and highly compensated jobs, according to a new study from a researcher at The University of Texas at Austin.
Because innovation is key to growth in high-tech economies, one strategy has been to give companies a tax break for it. As of 2022, 21 countries worldwide had reduced rates for income resulting from intellectual property (IP), such as patents, copyrights and trademarks. Prior research has shown that such policies, known as “innovation boxes,” ...
What is the relationship between sleep apnea and brain volume?
2023-05-31
MINNEAPOLIS – Studies have shown that sleep apnea is related to an increased risk of dementia. A new study looks at the relationship between sleep apnea and brain volume. The study is published in the May 31, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The study compared people who have the amyloid plaques in the brain that are an early sign of Alzheimer’s disease but do not have any memory problems to people with no amyloid plaques.
“We found that people with amyloid plaques who had more severe sleep apneas also were more likely to have lower volumes in the medial temporal ...
New nerve insights could someday help heal certain types of blindness and paralysis
2023-05-31
Injuries to the nerves can blind or paralyze because adult nerve cells don’t regenerate their connections. Now, a team of UConn School of Medicine researchers report in Development that at least a small population of nerve cells exist in everyone that could be coaxed to regrow, potentially restoring sight and movement.
Glaucoma. Optic neuritis. Trauma or stroke of the optic nerve. All of these conditions can irreversibly damage the optic nerve, leading to blindness. Glaucoma alone affects more that 3 million people in the US. Nerve damage leading to paralysis is similarly common, with around 5 million people in the US living with some form of it, according to the Christopher ...
Tribological mechanism of carbon group nanofluids on grinding interface under minimum quantity lubrication based on molecular dynamics simulation
2023-05-31
Since the interaction between the abrasive grain, workpiece and nanofluids on the minimum quantity lubrication (MQL) grinding interface are difficult to observe directly, there is still lack of direct evidence to reveal the internal mechanism of carbon group nanoparticles on the abrasive grain/workpiece grinding interface. Concerning this issue, the professor Changhe Li team, from department of Mechanical and Automotive Engineering of Qingdao University of Technology, China, using molecular dynamics simulation to study the tribological mechanism of friction-reducing and anti-wear of three kinds of carbon group nanoparticles, i.e., ...
