Hypertension May Ward Off Dementia
OBESITY: DIMINISHES COVID VACCINE PROTECTION The protection COVID-
19 vaccines off er declines more rapidly in people who are severely obese, say scientists at the Universities of Cambridge and Edinburgh. While participants had similar levels of antibodies to the COVID-19 virus six months after their second vaccine dose, 55% of the severely obese were less successful at neutralizing the virus compared to 12% of normal-weight people because the antibodies were not able to bind to the virus as eff ectively. However, when given a third dose of the vaccine, the ability of the antibodies to neutralize the virus was restored.
SHORT SAUNA S
cientists examined blood pressure readings of adults between the ages of 30
and 40 taken from 1954 to 1985. Brain health was assessed with brain scans conducted between 2017 and 2022. Compared to those who had normal blood pressure when they were young, participants who were prehypertensive or already had high blood pressure showed lower volumes of gray matter and other indicators of neurodegeneration in brain scans conducted in their senior years. Men appeared to be more vulnerable to the damaging eff ects of high blood pressure on the brain than women, according to the study published in JAMA Network Open. “High blood pressure is an incredibly common and treatable risk factor associated with dementia,” said Kristen M. George, Ph.D. “This study indicates hypertension status in early adulthood is important for brain health decades later.”
SESSIONS REDUCE BLOOD PRESSURE For a study by Brigham Young University
researchers, young and middle-aged men and women underwent two
20-minute sauna sessions at 176 degrees Fahrenheit. The researchers found that their specific method lowered body core temperatures more than techniques used in previous studies and reduced blood pressure. “This suggests we may not need to go to extremes to see improvements in cardiovascular health when using heat therapy over a longer period of time,” said master’s student Olivia Leach.
Coff ee Consumption Linked to Lower Blood Pressure
P
eople who drink two or three cups of coff ee a day have lower blood pressure than those who drink only one cup or none at all, according to a study by Italian researchers who examined the coff ee consumption and blood pressure levels of 720 men and 783 women. The study was published in the journal Nutrients.

BRAIN: EFFECTS OF MILD CONCUSSIONS LAST FOR MONTHS Even mild concussions can cause long-lasting
eff ects to the brain, according to research from the University of Cambridge. Concussions labeled as mild were linked with persistent symptoms, including depression, cognitive impairment, headaches, and fatigue, that can last for months. Six months afterward, 45% still showed symptoms caused by their brain injury.
PARKINSON’S: EXERCISE LOWERS ODDS Getting regular exercise, such as cycling, walking, gardening, and cleaning, may decrease the risk of developing Parkinson’s disease. A study published in Neurology that followed 95,354 healthy women for three decades found that those who exercised the most had a 25%
lower risk of developing Parkinson’s. “Exercise is beneficial and may help delay or prevent this
disease,” said study author Alexis Elbaz, M.D., Ph.D.
MARIJUANA: TRIPLES ARTERY DISEASE RISK Marijuana users have triple the risk of
developing peripheral artery disease (PAD), a condition that narrows arteries and reduces blood flow to the arms or legs, according to data from 30 million patients. “With the increase in marijuana use in the U.S., our findings show that users should be aware of the symptoms of PAD, such as leg pain while walking, slower or no hair growth, and feelings of coldness in the leg,” said researcher Hirva Vyas, of Hackensack University Medical Center.
