For decades, we've divided health into neat categories: mental health on one side, physical health on the other. The brain over here. The heart over there. Different specialists. Different appointments. Different silos. But biology doesn't respect those boundaries-and neither does depression. A growing body of research now makes something unmistakably clear: Depression is not only a disorder of mood and motivation; it is also a condition that affects the heart, blood vessels, and our long-term cardiovascular risk.
Our brain interprets grief as stress. As a result, it activates our stress-response systems, especially the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system. These systems release stress hormones such as cortisol and adrenaline, which are meant to protect the body in short-term crises. In acute grief, these responses are adaptive. They help us cope with shock and disruption. If unresolved, however, the same systems can become dysregulated.
Angus Burns, a postdoctoral fellow at Harvard Medical School and Brigham and Women's Hospital, said the work highlights the potency of our circadian rhythm, which not only regulates sleep, but also independently affects nearly every organ in the body, changing how they function when we nod off. For those experiencing the brightest nights, the research showed increased risk of between 30 percent and 50 percent for heart attack, stroke, heart failure, atrial fibrillation, and coronary artery disease.
A large study led by scientists at McMaster University has found that fat stored deep inside the abdomen and liver can quietly injure arteries, even in people who seem healthy on the outside. The research, published on October 17, 2025, in Communications Medicine, questions the long-standing use of body-mass index (BMI) as a reliable indicator of obesity and heart risk. It offers new evidence that the fat people cannot see may be just as dangerous as the weight they can.
To collect wine, or any alcohol, is to curate not only bottles but stories, memories, and aspirations. A cellar becomes a gallery of taste and time: a 1990 Bordeaux resting beside a Sonoma Pinot Noir, each label recalling moments of celebration, of refinement, even of restraint. Collectors often speak of wine as a living art, something to be admired and shared, not merely consumed. But as new research from Stanford University reveals, the science of alcohol consumption is increasingly at odds with the romance
Between 2021 and 2023, cannabis use among Americans 65 and older went up 46%, according to a study published in JAMA Internal Medicine. Crawley said those numbers reflect that marijuana is a "good solution to a lot of medicinal issues." And with cannabis now legal in 40 states for medical use and 24 for recreational, according to the National Conference of State Legislatures, the stigma is quickly diminishing.
Women with type 2 diabetes should consider switching their HRT tablets to patches to reduce their risk of potentially fatal blood clots, according to a new study. Researchers have found women with the condition who take an oral form of HRT have double the risk of a pulmonary embolism - when a blood clot blocks an artery in the lung - than those using skin patches. They also have a 21 per cent increased risk of heart disease, the study revealed.
