Health Alert: Air Quality During Heatwaves Can Place Senior Lives in Peril.
An analysis of Medicare data from summer months between 2000 and 2016 found that air quality worsens during heatwaves, which can exacerbate cardiovascular and respiratory disease in older adults. It is estimated that roughly 1 in 4 excess deaths among seniors during heatwaves may be linked to reduced air quality. These findings suggest that efforts to mitigate air pollution during heatwaves could help save lives among the most vulnerable older adults.

Diet: Unhealthy Childhood Diet Can Influence Long-Term Brain Health.
A recent animal study found that mice fed a high-fat, high-sugar diet early in life experienced detrimental alterations in hypothalamic activity that persisted into adulthood. Interestingly, subsequent dietary changes that supported gut health helped counter these effects. These findings highlight the importance of diet in supporting long-term brain health.

Exercise: Menstrual Hormones May Affect How Hard Exercise Feels, Not Performance.
In a recent experiment, researchers found that a woman’s maximal metabolic steady-state intensity remains stable throughout the menstrual cycle. However, when progesterone levels were higher, participants reported their workouts felt more difficult, suggesting that hormonal fluctuations may influence perceived exertion rather than physical capacity.

Chiropractic: Exercise Therapy Eases Pain and Disability in Whiplash.
Patients with chronic whiplash-associated disorders (cWAD) often exhibit dysfunction in superficial neck muscles, such as the trapezius. A study that included individuals with cWAD found that those who participated in a three-month neck-specific exercise program experienced significant improvements in neck pain, disability, and muscle fatigue. These findings support the role of neck-specific exercises as part of a multimodal approach to managing cWAD.

Mental Attitude: Stroke-Related Blood-Brain Barrier Disruption May Raise Dementia Risk.
A recent study found that patients with a history of stroke exhibit impaired function of the blood-brain barrier—a protective filter that allows nutrients into the brain while blocking harmful substances. Disruption of this barrier may allow harmful substances to accumulate in the brain and impair cognitive function, which may help explain why stroke doubles the risk of dementia.

Wellness/Prevention: Cannabis Compounds Show Potential Against Fatty Liver Disease.
Metabolic dysfunction-associated steatotic liver disease (MASLD) is a form of liver disease linked to poor metabolic health rather than excessive alcohol use. A recent laboratory study found that two non-psychoactive cannabis compounds—cannabidiol (CBD) and cannabigerol (CBG)—may enhance cellular energy reserves and support the recycling systems that help remove harmful fats and waste from liver cells. If confirmed in large-scale human studies, these compounds may play a role in the future treatment of MASLD.
