Light exposure during nighttime sleep may lead to harmful changes in the heart's structure and function, according to a study published this week.
Researchers asked 11,071 participants without cardiovascular disease to wear light and motion sensors on their wrists for seven days to measure nighttime light exposure. Possible sources included streetlights and televisions. Participants underwent cardiac MRIs three years later, and those with greater exposure had thicker heart walls and weaker heartbeats. During eight- to 10-year follow-ups, those in the highest-exposure group had a 29% higher risk of heart failure, 24% higher risk of heart attack, 33% elevated risk of stroke, and 26% increased risk of cardiovascular death than those with the least exposure. See seven tips to limit nighttime light here.
Further research is needed to determine whether different types of light, such as LED versus fluorescent, have different effects. Future studies may also probe whether the changes stem from disrupted sleep or effects on the body's circadian rhythm. |

US inflation accelerates and diesel prices spike as war in Iran continues.
The inflation rose 3.4% in August compared with a year ago, unchanged from July and in line with analysts’ expectations. Interest-rate futures forecast about an 85% chance the Federal Reserve will raise interest rates next week, up from roughly 70% before the report. Meanwhile, diesel prices hit record highs above $6 a gallon, which is expected to hike the cost of shipping groceries and other goods. (More) |

The moves tighten Iran and its allies' control of the Bab el-Mandab Strait, a vital oil shipping route. Meanwhile, Saudi Arabia shut down a major oil pipeline after a drone attack it claims originated in Iraq. The Iraqi government has ordered an investigation. (More, w/map) |
Afghan woman deported in first-ever "alien terrorist" court case.
Nazira Haji Zada, a 47-year-old Afghan permanent resident living in Texas, opted yesterday to leave the US rather than continue litigating accusations that she supported an Islamic State-linked plot. She was the first person to appear before the Alien Terrorist Removal Court, which was established in 1996. The court allows the government to deport noncitizens whose case details cannot be publicly disclosed for national security reasons. (More) |

Today, we're sharing a story from reader Cathy K. in Rescue, CA.
"It was early Sunday morning. My husband and I had spent the night in a rest stop in our travel trailer in Blythe, California, before heading into Arizona. We had driven 70 miles east before realizing he didn’t have his wallet. We decided to drive back to the rest stop when I received a call from our health insurance company. They had a gentleman on the other line who had found the wallet at the rest stop. The only phone number available was on this insurance card. The insurance company connected us so that we could talk. The couple waited for us at the rest stop, still holding the wallet. We will never forget the kindness of these strangers."
