A dream vacation, an exotic destination, a long-haul flight and finally some well-deserved rest. The problem is that many travelers arrive at their destination only to spend the first days of their vacation struggling with fatigue, sleep disturbances, low energy levels and digestive issues. Researchers from Wroclaw Medical University point out that these symptoms may be caused by more than classic jet lag. A growing body of evidence suggests that time zone changes also affect the trillions of bacteria living in our intestines.

A Cleveland Clinic-led study shows a connection between elevated blood levels of TMAO (trimethylamine N-oxide)—a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products—and a higher risk of atrial fibrillation.

Engineers at the University of California San Diego created a smart ring that simultaneously and continuously monitors up to four different chemical biomarkers from finger sweat. The biomarkers the smart ring can monitor in sweat are glucose, ketones, vitamin C, uric acid, lactate and alcohol.

Many of us have grown up with the mantra that breakfast is the most important meal of the day. But whether it’s snatching an extra half hour of sleep or focusing on getting the kids out of the house, there are various reasons why assembling a healthy breakfast might slip down your list of priorities—especially on a weekday.

Cerebral small vessel disease (CSVD), which notably increases the risk of stroke and cognitive disorders, is estimated to affect more than 5 million people in France alone. In the absence of a curative treatment, preventing cardiovascular risk factors remains the most effective strategy today. However, promising new therapeutic avenues are being explored.

Researchers at the University of Hawaiʻi at Mānoa have found that certain gut bacteria are linked to how quickly the body ages, providing new insight into the connection between the gut, health and longevity.

Although American Indian and Alaska Native (AIAN) adults make up 5% of California’s adult population, they shoulder a disproportionate burden of chronic disease and substance use, according to a new study from the UCLA Center for Health Policy Research (CHPR).

Cardiovascular risk factors are linked to a higher risk of heart disease, but it has been unknown how they are related to abrupt closure of the coronary arteries leading to heart attack and sudden cardiac death. A study by Mass General Brigham Heart and Vascular Institute investigators finds that people with a greater modifiable risk factor burden, such as high blood pressure, high cholesterol, diabetes, smoking and obesity, have more widespread plaque buildup in major coronary arteries.

A panel of federal health advisers on Thursday narrowly recommended easing access to several peptides popular with wellness influencers and celebrities, despite warnings from government scientists that the chemicals haven’t been shown to be safe or effective.
