In a new study from the University of Oregon, scientists turned up the temperature to see which type of passive heat therapy packs the most health punch – hot baths, traditional saunas, or those fancy far-infrared saunas.

Adding to the growing body of research that proves our microbiome is a powerful ally in fighting disease, scientists have found that an easy-to-get nutrient in our food causes our guts to produce powerful insulin-regulating compounds.

Researchers are using a laser-based imaging technique to map these tiny particles deep within the tissues of mice without surgery. This offers a fresh perspective on how microplastics move through the body and their long-term effects on human health.

As some 150 million Americans dig into a hot dog on the July 4 weekend, physicians have uncovered how little we actually know about the health risks of this kind of processed meat. In fact, close to 90% of US adult surveyed poorly informed.

A wave of unregulated peptides is sweeping the wellness world and now crossing into the mainstream. But concern is growing about side effects, and almost nobody is asking whether these substances impact men and women in the same way.

A new review presents comprehensive and convincing research that ties common sugar substitutes to metabolic disturbances that begin in the gut and then flow throughout the body. It also highlights issues of food-label transparency in the US.

A new study from Washington University School of Medicine in St. Louis, drawing on tens of thousands of participants in the UK and the US, suggests that the risk of developing cancer isn't just a matter of birthdays; it's about how fast bodies age biologically.

A flower you may have in your backyard or have seen in a public garden has been found to contain a surprisingly high amount of protein, as well as other nutrients. It could transform how we think of "ornamental" plants – and flowers in general.

Some estimates suggest up to one in 30 people may be affected by developmental topographical disorientation (DTD). This condition has been described as a lifelong inability to orient oneself – even in extremely familiar surroundings.

An opioid drug with a low risk of addiction and respiratory depression has emerged as a promising candidate for treating chronic pain and pruritus, a condition that compels people to scratch their skin. And it's already on the market.

Strength training has long been seen as something you mainly do to build muscle or look good. But a new study adds to a growing body of evidence that shows lifting weights does far more than change how we look. It may help us live longer.

Melatonin – a go-to sleep aid for kids and adults alike in many households in the US – continues to create media buzz, with conflicting messages that leave people uncertain about its safety. A pediatrician and sleep medicine doctor weighs in.

A modified diet that takes cues from the Mediterranean model has the potential to promote healthier aging, with scientists using a large dataset from human records and combining it with an animal study to work out just why this could be.

If weak bones increase the risk of fractures, surely taking more calcium and vitamin D should help keep bones strong. But a major new study suggests the reality may be far more uncertain.

Five weeks of walking around with poles in each hand could have a surprising effect on anyone with moderate depressive symptoms. What's more, it's also a low-impact workout that can suit people who are otherwise lacking energy or motivation.

A new study has uncovered evidence of “synaptic down-selection” as we sleep, suggesting our nightly shut-eye is a perfect opportunity to prune back any neurological hedges that went wild during the day.
