If you can’t remember the last time you washed your bedsheets, experts say it’s probably been too long. Dermatologists recommend laundering bedding at least once a week. Over just a few nights, sheets accumulate sweat, dust, pet dander, and pollen—conditions that encourage bacteria growth and create an ideal environment for dust mites.
In the animal world, researchers at the University of Cambridge have uncovered surprising similarities between humans and golden retrievers. Their work points to specific genes in the breed that relate to traits such as anxiety, depression, and intelligence, offering fresh insight into canine behavior and the genetic links we may share.
Meanwhile, health scientists continue to emphasize the importance of consistent sleep routines. Beyond maintaining a healthy weight, exercising, and reducing sodium intake, a regular bedtime may also help lower high blood pressure. A study from Oregon Health & Science University found that sticking to the same bedtime each night reduced nighttime blood pressure and potentially lowered the risk of cardiovascular events.
From cleaner bedding to predictable sleep schedules—and even understanding our canine companions—these findings highlight how small habits and new research can make a meaningful difference in everyday health.
