A study links inadequate deep and REM sleep to brain shrinkage, an early sign of Alzheimer’s. Deep sleep helps clear toxins, while REM processes emotions and memories. Experts recommend consistent sleep routines, dark environments, and avoiding alcohol before bed to improve sleep quality and brain health.
Fitness results vary by individual, with visible changes often taking 4–12 weeks. Factors like metabolism, exercise type, and diet play key roles.

A study from the University of California - Riverside suggests that menthol-flavored e-cigarettes may harm fetal development. Researchers found that menthol activates stress-related channels in the blood, leading to increased cell death and migration. The findings add to concerns about vaping’s safety during pregnancy.
Colorectal cancer is a leading cause of cancer deaths in the U.S. Risk factors include obesity, diet, and genetics. Screening is recommended from age 45, with earlier testing for high-risk individuals. Detection methods range from colonoscopies to stool tests. Lifestyle changes and regular check-ups help reduce the risk.
New research questions BMI's accuracy in assessing obesity in aging adults. Despite similar BMIs, older individuals store more torso fat and lose limb muscle, increasing health risks. Researchers recommend alternatives like waist-to-height ratio and muscle assessments. BMI alone may misrepresent obesity, emphasizing the need for better evaluation methods.
