CNN —It was a dream come true for millions of Taylor Swift fans, after the superstar released her latest album, “The Tortured Poets Department,” at midnight on Friday. “The strongest reset for the circadian system is bright light,” said Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine at Northwestern University Feinberg School of Medicine in Chicago. “Research shows that movement can boost circulation and increase alertness, helping you shake off that sleepiness faster,” Daddy Dasgupta said. “It could limit your ability to sleep well that night,” said sleep specialist Kristen Knutson, an associate professor of neurology and preventive medicine at Northwestern University’s Feinberg School of Medicine. And of course, listening to Taylor Swift counts as long as you turn it off before bed!”CNN’s Madeline Holcombe, Kristen Rogers and Ashley Strickland contributed Taylor Swift lyrics to this article.

☆ Night owls may die younger, but more than sleep is to blame

A 2022 study found night owls were more sedentary, had lower aerobic fitness levels, and burned less fat at rest and while active than early birds. Night owls were also more likely to be insulin-resistant, meaning their muscles required more insulin to be able to get the energy they need, the study showed. Studies have revealed night owls may take more risks and are more likely to skip breakfast and eat more later in the day. Night owls also have higher levels of visceral body fat in the abdominal region, a key risk factor for type 2 diabetes and heart disease. “The strongest reset for the circadian system is bright light,” Zee said.

Stroke risk is typically higher in older adults with more health problems, the study noted. After controlling for other factors that contribute to stroke risk, researchers found people with five to eight symptoms of insomnia had a 51% increased risk of stroke compared with people who did not have insomnia, according to a statement on the study published Wednesday in the journal Neurology. In comparison, people who had one to four symptoms had a 16% increased risk of stroke compared with people with no symptoms of insomnia, the study found. Getting more than nine hours of sleep on average was linked with a twofold increase in stroke risk. However, taking a planned nap of less than an hour was not associated with an increased stroke risk, the study said.

☆ Is your job ruining your sleep? If so, this may be why

Experiencing negative changes in workplace leadership and fairness was associated with the strongest long-term impact on a worker's sleep. LumiNola/E+/Getty ImagesSleep problems included initiating or maintaining sleep, poor-quality sleep and daytime tiredness two to four times a week that lasted one month to three months. Within a two-year period of time, over half of the participants (53%) reported changes in their workplace environment. However, if the changes at work were negative, sleep issues increased — in fact 1 in 4 people in the study with a worse job environment developed problems getting enough rest. Having negative changes in the leadership and fairness sector was associated with the greatest long-term impact on sleep, more than negative changes in coworker relationships or collaboration, the study found.

CNN —Sleeping in a room exposed to outdoor artificial light at night may increase the risk of developing diabetes, according to a study of nearly 100,000 Chinese adults. Urban light pollution is so widespread that it can affect suburbs and forest parks that may be tens, even hundreds, of miles from the light source, the authors said. “Studies have suggested that inconsistent sleep patterns have been linked to an increased risk of type 2 diabetes,” he said in a statement. Blood samples were collected and compared with satellite imagery of light levels in the area of China in which each person lived. The analysis found chronic exposure to light pollution at night raised blood glucose levels and led to a higher risk of insulin resistance and diabetes.

☆ Permanent Daylight Saving Time will hurt our health, experts say

We’ll move them forward (again) next spring when governments put daylight saving back in place. Not according to the United States Senate, which in March passed the Sunshine Protection Act of 2021 – if it becomes law, Daylight Saving Time will be permanent. Our bodies need the early morning light to set our internal body clock, experts say. When President Richard Nixon signed a permanent Daylight Saving Time into law in January 1974, it was a popular move. “The United States has tried permanent daylight saving time twice before and ended it early.
