Health Alert: Women Face Higher Heart Risk at Lower Plaque Levels. Atherosclerosis is characterized by the
hardening and narrowing of the arteries, which can lead to potentially dangerous blockages if left untreated. A recent
study found that a woman’s risk of heart attack or hospitalization for chest pain begins at a lower level of arterial
blockage (20% vs. 28% in men), suggesting that standard risk thresholds may underestimate heart disease danger in
women and support the need for sex-specific prevention guidelines.

Diet: Healthier Diet Linked to Lower Colorectal Cancer Risk. A large international study that included nearly
one million adults found that a diet pattern characterized by a high intake of fruit and vegetables (especially leafy
greens), legumes, dairy, coffee, and tea, and lower consumption of red and processed meats and sugary drinks is
associated with a lower risk of colorectal cancer. American Journal of Clinical Nutrition, January 2026
Exercise: One Reason Too Much Sitting Is Unhealthy. Serum osmolality is a measure of the concentration of
dissolved particles in the liquid portion of the blood, reflecting the body’s fluid and electrolyte balance. Higher
serum osmolality has been associated with poorer cardiovascular outcomes. A recent study found that as sitting time
increases, so does serum osmolality—possibly due to reduced hydration, greater consumption of diuretic beverages,
delayed bathroom breaks, and elevated blood sugar levels from snacking. The findings point to one potential
mechanism by which prolonged sitting may negatively affect cardiometabolic health.

Chiropractic: Cycling and Low Back Pain. Among 1,521 cyclists, researchers found that 29.2% reported
experiencing low back pain within the previous year. Further analysis showed that younger riders, those with greater
body mass, and mountain bikers were at higher risk. Journal of Bodywork and Movement Therapies, December 2025
Mental Attitude: Cognitive Training Benefits Chronic Brain Injury Patients. Brain imaging conducted before
and after a 14-week computerized cognitive training program revealed significant improvements in white matter
microstructure among adults with chronic traumatic brain injury, particularly in regions associated with processing
speed, attention, and working memory. Journal of Neurotrauma, January 2026
Wellness/Prevention: Clean Indoor Air Key to Reducing Adult Asthma Attacks. New research suggests that
homes with air purifiers, proper airflow, no exposure to secondhand smoke, and fewer allergens—such as mold,
pests, or pet dander—are associated with fewer asthma attacks, better sleep, and improved daily activity among
adults with asthma. Atmosphere, February 2026
