Hair Cortisone Predicts Metabolic Syndrome in Young Adults
METHODOLOGY:
Researchers in the Netherlands conducted a cross-sectional study to investigate the relationship between hair glucocorticoid levels and the presence of MetS and its components in 1405 adult participants (median age, 49 years; 73.6% women) from the Netherlands Study of Depression and Anxiety cohort.
Levels of hair glucocorticoids (cortisol and cortisone) were measured using liquid chromatography-tandem mass spectrometry.
Outcomes were the presence of MetS and its individual components that included high-density lipoprotein cholesterol, fasting glucose, and triglyceride levels; diastolic blood pressure; and waist circumference.
This study also assessed whether age (≤ 49 vs ≥ 50 years) modified the relationship between hair glucocorticoids and MetS.
TAKEAWAY:
Hair cortisol (odds ratio [OR], 1.27) and cortisone (OR, 1.32; P < .001 for both) levels were strongly associated with MetS, with the association between hair cortisone and MetS being significantly modified by age (OR, 0.78; P = .003).
< .001 for both) levels were strongly associated with MetS, with the association between hair cortisone and MetS being significantly modified by age (OR, 0.78; = .003). The link between hair glucocorticoids and MetS was stronger in younger participants than in older ones for both hair cortisol (OR, 1.52 vs 1.20) and hair cortisone (OR, 1.95 vs 1.14).
Hair cortisol and cortisone levels were positively correlated with waist circumference ( P < .001 for both) and triglyceride levels ( P < .025 for both); hair cortisol, but not cortisone, levels were also positively associated with diastolic blood pressure ( P = .034) and negatively associated with high-density lipoprotein cholesterol levels ( P = .035).
IN PRACTICE:
"In the future, [the study] findings can be used to identify individuals with increased cardiovascular risk," the authors wrote.
SOURCE:
This study was led by Susanne Kuckuck, Erasmus MC, University Medical Center Rotterdam, Rotterdam, the Netherlands. It was published online on June 03, 2025, in The Journal of Clinical Endocrinology & Metabolism .
LIMITATIONS:
The study population was predominantly Caucasian, which limited the generalisability of the findings to other populations and ethnic minorities. Information on diet was not collected; hence, the potential influence of nutritional factors on glucocorticoid metabolism could not be assessed. This study could not show whether elevated hair glucocorticoid levels caused MetS due to its cross-sectional design.
DISCLOSURES:
This study was supported by Stress in Action, a research project financially supported by the Dutch Research Council and the Dutch Ministry of Education, Culture and Science. The authors declared having no conflicts of interest.

Time Your Meals, Tune Your Metabolism
New research from UC San Diego has revealed fascinating insights into how timing our meals might significantly affect our metabolic health by aligning with our body's natural microbial rhythms. Just as our bodies follow circadian rhythms, our gut microbes have their own daily patterns, with certain beneficial activities increasing during our active periods to help with digestion and metabolism. The study found that unrestricted access to high-fat foods disrupted these natural patterns, leading to unusual daytime eating and metabolic dysfunction — similar to what human shift workers experience when their eating cycles don't match their biological clocks. Using cutting-edge metatranscriptomics technology, researchers identified a specific enzyme called bile salt hydrolase that plays a crucial role in metabolic improvements. When engineered into beneficial bacteria, this led to increased lean muscle mass, reduced body fat, and better blood glucose regulation. These findings could potentially lead to new targeted therapies for common metabolic disorders, offering hope for those struggling with obesity and diabetes. This breakthrough not only demonstrates the significant influence of circadian rhythms on microbial function, but it also provides a new method for testing how specific microbial activities affect our metabolism through engineered gut bacteria.

Looking for a beautiful, low-maintenance, quiet and long-living cat? This is the breed for you –and everything you need to know
When you buy through links on our articles, Future and its syndication partners may earn a commission. Russian Blue cat overview Other names: Archangel Blues Life expectancy: 15–20 years Size: 8-10 inches (height), 15–18 inches (length) and 8–15 lb (weight) Coat: solid steel blue Eye colour: green eyes Temperament: devoted, intelligent, sensitive and intuitive Origin/native country: Russia Celebrated for their blue-silver coats, elegant build and low-key energy, the Russian Blue is the perfect mix of beauty and grace. As their name suggests, these feline companions hail from Russia – in the bustling port city of Arkhangelsk, to be exact – and they are a naturally occurring breed. They get their name because of their illustrious blue coat that has a silvery sheen throughout. You might think all this fur requires hours worth of upkeep, but the truth is, Russian Blues are pretty low maintenance on all fronts. This breed can also be a godsend for allergy-prone households because Russian Blues produce less of the allergy-triggering protein found in cats when compared to other breeds. Another fun fact about this beautiful, long-living breed? They are an intelligent, relatively independent and quiet breed, so are best suited for homes that can match this understated energy. If you're considering bringing a Russian Blue home, you'll find everything you need to know in this guide, including their health conditions, enrichment needs, and more. Are Russian Blue cats hypoallergenic? 'Russian Blue cats are not truly hypoallergenic, but may suit some owners with mild allergies,' explains vet Dr Rebecca MacMillan. 'This is because Russian Blues produce less Fel d1 protein in their saliva and urine than many other breeds,'. In the cat realm, Fel d1 is the protein that triggers reactions in those allergic to cats. Therefore, if you are in an allergy-prone household, it's worth reading up on the hypoallergenic cat breeds, like the Siamese, Burmese and the LaPerm, as these pets either produce less of the allergy-triggering protein and/or don't shed too much, which can make them an ideal proposition for allergy sufferers. Do Russian Blue cats shed? Russian Blues do shed some of their shimmering coat, but only minimally so this means you won't find too many loose hairs around your home! 'This can also help allergy sufferers as there will be less saliva-coated hair and dander in the environment,' Dr MacMillan says. 'Just remember that very sensitive people may still react.' For those who would prefer not to have tons of fur all over their clothing, floors and furniture, the non-shedding cat breeds are well worth considering. How long do Russian Blue cats live? Russian Blue cats are pretty long-living cats. So much so, many Russian Blues live until they are between 15–20 years of age with the right care. According to Dr MacMillan, if you want to increase the chances of your cat having a long and healthy life, then there are several things you can do. 'Make sure they are receiving the correct amount of a good quality diet, appropriate for their age and lifestyle,' the vet notes. 'Also monitor their weight closely, as cats that are overweight or obese can have significantly shorter life spans." Thirdly, Dr MacMillan suggests taking your cat to the vets for routine check-ups and ensuring they have all the recommended vaccinations. 'This will keep them safe from potentially fatal diseases,' she says. While regular anti-parasite treatment, like the best flea treatments for cats, will also help to keep them healthy, as will regular preventative oral care. How much grooming does a Russian Blue cat need? If you're considering adopting a Russian Blue, you'll be pleased to know that these cuties have easy grooming requirements. 'Their short coat only needs brushing once a week to remove any loose hairs,' Dr MacMillan says. 'I also recommend introducing regular oral care from an early age. Many cats will tolerate gentle toothbrushing with cat-safe toothpaste, if you encourage this with positive reinforcement training.' As Dr MacMillan says, to help keep cat teeth clean, it's important to get into a good teethbrushing routine. It's also well worth learning how to brush your cat's teeth, so that you can avoid dental disease, like stomatitis and gingivitis, and boost your cat's longevity and quality of life. How much exercise does a Russian Blue cat need? Russian Blues have moderate exercise needs and are not as demanding as some other cat breeds, like an Abyssinian, Bengal or Siamese, which are all high-energy cat breeds that will want to play with you all the time. 'Around 30 minutes of activity a day should be enough to keep them happy,' Dr MacMillan says. So, if you plan on bringing a Russian Blue home, the best cat toys and the best automated cat toys will help keep your kitty entertained. Wisdom Panel Cat DNA Test | Amazon Not sure exactly what breed your cat is? This kit screens for 70+ breeds, 45 genetic health insights and 25+ physical traits – because knowing every detail about your cat helps you understand how best to care for them. View Deal Russian Blue health problems Dental disease is common in many cats and Russian Blues are no different because dental issues in cats often go unnoticed. 'Excessive tartar buildup and gum inflammation can lead to tooth loss,' explains Dr MacMillan. 'That is why preventative oral care is so important.' Obesity is another health condition common in Russian Blues, as it can be hard to say no to those cute little faces! 'However, obesity is linked to an increased risk of other ailments like diabetes, joint disease, and cancer,' Dr MacMillan highlights. 'Owners must weigh their pet's food out carefully and keep an eye on their cat's body condition, to ensure they don't put on any extra pounds.' As with many pedigree breeds, hypertrophic cardiomyopathy can be a problem for Russian Blues. 'This condition causes thickening of the muscular heart walls,' the vet explains. 'This affects the heart's ability to effectively pump blood around the body. Heart failure can occur, as well as blood clots and sudden death.' Hypertrophic cardiomyopathy is an inherited condition so purchasing your kitten from a reputable breeder who has screened their cats will reduce the risk. Asthma in cats isn't uncommon and it's a respiratory condition that can affect this breed. 'In affected cats, the body overreacts to inhaled allergens leading to inflammation and constriction of the airways,' Dr MacMillan says. 'Asthmatic cats can have breathing difficulties, wheezing, and start open-mouth breathing.' If any of these symptoms occur, owners must seek urgent help from a vet if their cat is showing any signs of asthma. 'Reducing things like cigarette smoke, air fresheners and scented candles in the environment can help ease symptoms, but many cats will require long-term medication too,' Dr MacMillan adds. How much does a Russian Blue cost? Russian Blues are pretty expensive cats. Costing anywhere between $1,400–3,800, their distinct appearance and pleasing personality traits make them particularly desirable – and therefore on the pricier side. This is around the same price tag as a Bengal or Savannah cat. Though Russian Blues aren't considered to be one of the rarest cat breeds in the US, they aren't your everyday cat you might come across. Should I get a Russian Blue? That depends. The long-living Russian Blues are sweet-natured kitties who thrive in human company. These cats are a relatively quiet breed and can get a bit scared by noisy children, bouncy dogs, or strangers. This is why Dr MacMillan suggests they would be best suited to a peaceful household, perhaps an elderly owner or a family with calmer, older children. Due to the fact Russian Blues produce less Fel d1 protein in their saliva and urine than many other breed and shed minimally, this breed might also suit allergy sufferers or those who don't want to spend all day picking up after their kitty. Although they enjoy playing, they also like a bit of alone time and will often take themselves off for a nap. 'They are usually content being left for short periods too, if you need to head out for a bit,' Dr MacMillan adds.

Weighted Vests: Are They Effective for Weight Loss?
With the ongoing obesity epidemic, researchers are constantly looking for strategies that optimize weight loss while minimizing associated side effects. One strategy currently gaining interest is the use of weighted vests— form-fitting garments into which weights are sewn or carried in pockets, enabling the wearer to add or remove them as needed. In theory, this offers a nonpharmacologic way to induce weight loss without the side effects of medications or weight-loss surgery, but with potential bone-sparing effects. The latter is important because even modest weight loss can reduce bone density and strength, increasing the risk for fracture. Weight loss — particularly when induced by caloric restriction — is associated with bone loss, especially at the hip. This is a consequence of loss of muscle mass and an unloading of bones from the decrease in body weight. Even modest diet-induced weight loss results in small but significant reductions in hip bone mineral density (BMD), with less consistent changes at the spine or whole body. These skeletal losses may increase fracture risk, particularly in older adults, and are more pronounced when weight loss occurs in the absence of exercise. Resistance training or combined aerobic-resistance exercise mitigate but do not fully prevent this bone loss. How Do Weighted Vests Help? Weighted vests can be used to preserve muscle mass during periods of caloric restriction. This is achieved by increasing gravitational loading and placing mechanical stress on weight-bearing tissues. Local fat mass is theoretically reduced by the work required to wear the weighted vest. Preservation of muscle mass has the dual benefit of preserving bone mass and maintaining resting metabolic rate (RMR). This is important because weight loss typically results in a lower RMR, which makes subsequent weight loss more difficult. Although using weighted vests does not lead to the same degree of weight loss reported with GLP-1 receptor agonists such as semaglutide, or GLP-1/glucose-dependent insulinotropic peptide (GIP) receptor agonists such as tirzepatide, the data demonstrate benefits of this strategy. For example, 5 weeks of high-load vest use (11% of body weight worn 8 hours per day) vs a low-load vest (1% of body weight) reduced fat mass and waist circumference with no significant change in overall body weight. Loss of fat mass and a reduction in waist circumference are not inconsequential outcomes. Fat distribution (particularly an excess of visceral fat with an increased waist circumference) is a major driver of many metabolic morbidities associated with obesity. In fact, newer definitions of preclinical and clinical obesity emphasize body fat distribution and waist circumference, rather than absolute body weight. The impact of weighted vest use on skeletal health is inconclusive at this time. Snow and colleagues reported preservation of hip BMD over a 5-year period in older, postmenopausal women when weighted vest use was combined with jumping exercises. However, a randomized controlled study from Wake Forest University (INVEST in Obesity) involving 150 older adults with obesity did not find a bone-protective effect of weighted vest use or resistance training following intentional weight loss. Further studies are needed to evaluate the impact on BMD of varying durations of vest use and varying weights of the vest. In conclusion, studies thus far have not demonstrated a significant impact of weighted vests for total weight reduction, although reductions in local fat mass and waist circumference may confer some metabolic benefit. These vests may provide mechanical stimuli that support musculoskeletal integrity; however, further research is necessary to prove this point and data available thus far are conflicting.
