How do anxiety and stress differ?

This article explains that though “stress” and “anxiety” are often used interchangeably, there are distinct differences between the two. Stress is defined as the body's response to an external trigger and can be classified as acute or chronic. Anxiety, however, tends to be triggered internally by excessive thoughts and judgement.

Beautiful spaces filled with light and natural motifs aren't just aesthetic, but likely key to your health. Researchers had study participants view photographs of two distinct buildings, one designed with more natural elements while the other featured more abstract shapes and lines. Using electroencephalograph readings of each participant, they discovered participants had less brain inflammation while viewing the "biophilic," or natural, architecture. Learn more about the interdisciplinary framework of so-called neuroarchitecture here.

At-home genetic testing results commonly led users to healthier lifestyles

Italian research that aimed to investigate what people do longer-term after receiving direct-to-consumer genetic test results indicated that whether the results were positive or negative, people tended to adopt a healthier diet after receiving the results, and they'd still maintained it a year after receiving their results. Some users also reported an overall reduction in stress over their health concerns. (Some users may encounter a paywall.)

SAD uniquely affects people with attention-deficit hyperactivity disorder
