Blue Light Can Be Hazardous To Your Health

BOSTON (CBS) – From our phones and computers to the lights in our homes, we are constantly bombarded with blue light, and nighttime exposure can be hazardous to your health. Edward Takach has trouble falling asleep and staying asleep, so he’s made big changes at home. “It’s just become regular routine,” Takach said. Edward Takach has made changes to his exposure to blue lights. (WBZ-TV) His television, tablet and computer are set up so he sees warmer colors from dusk to dawn. So is the lighting in his home. He is trying to block blue light from electronics and energy efficient light bulbs at night. “It does help me personally, as a sleep patient, feel more ready for sleep and get to sleep a lot easier,” Takach said. Dr. Charles Czeisler of Brigham and Women’s Hospital has been studying blue light for years. He says exposure at night throws off the body’s biological clock and suppresses the release of the sleep hormone melatonin. “We’ve done studies showing that if we read, for example, from an iPad in the few hours before bedtime, that that resets our circadian clock by about an hour and a half later,” Dr. Czeisler explains. Nighttime exposure to blue lights can be hazardous to your health. (WBZ-TV) There’s also evidence that exposure to blue light at night may not just affect sleep. “Shifting our circadian rhythms repeatedly has been associated with an increased risk for various types of canc...

Conclusions: Hyperthermia increased the serum neutrophil-recruiting cytokine levels and reduced the magnitude of chemotherapy-induced neutropenia. Thus, HIPEC improved neutrophil and bone marrow recovery compared with conventional IP chemotherapy. PMID: 31818168 [PubMed - in process]

Authors: Taylor CR, Dominguez JE, Habib AS Abstract Obesity is a significant global health problem. It results in a higher incidence of complications for pregnant women and their neonates. Cesarean deliveries are more common in obese parturients as well. The increased burden of comorbidities seen in this population, such as obstructive sleep apnea, necessitates antepartum anesthetic consultation. These patients pose unique challenges for the practicing anesthesiologist and may benefit from optimization prior to delivery. Complications from anesthesia and overall morbidity and mortality are higher in this population...

Authors: Wang J, Zhang Y, Lu X, Xi C, Yu K, Gao R, Bi K Abstract Background: Idiopathic granulomatous mastitis (IGM) can clinically and radiographically mimic an abscess or breast cancer. Although IGM is benign, it can cause the breast skin to appear "riddled with holes" and can even result in the loss of the breast. The optimal treatment has not been established. Methods: We retrospectively studied the medical records of 200 patients with IGM who were treated for skin rupture from June 2015 to June 2017 in our institute. The patients' treatment modalities (including surgery after steroid therapy and ster...

The objective of the present study was to ascertain masticatory efficiency by evaluating electromyographic activity in the masseter and temporalis muscles in subjects with sleep bruxism of varying severity, as determined by BiteStrip. Thirty-four subjects with sleep bruxism were divided into two groups: a mild sleep bruxism group with a mean (± standard deviation) age of 31.3 ± 6.2 years (n = 15) and a severe sleep bruxism group with a mean age of 29.8 ± 7.1 years (n = 19). Full-night polysomnography (PSG) was performed in eligible subjects. The linear envelope integral was used to determine masticator...

Conclusion This opinion piece discusses the evidence related to whether exposure to electrical light night is a health risk. Much of the article considers various experimental studies where small numbers of participants were exposed to different light levels at night, as well as observational studies reportedly linking night-shift work with cancer, including breast and colon cancer. The researchers also identified some studies linking self-reported or measured light in the bedroom with depression and obesity. But this study has two prominent limitations. It does not appear to have been a systematic review. No methods are...
