Jan 13, 2023 - Having strong social connections can improve your health, according to global study - University of Kent
"The study also found that having strong bonds with both close social circles and extended groups is associated with better mental health and wellbeing. Importantly, the greater number of groups people had strong bonds with, the higher their engagement in health behaviours and the better their reported psychological wellbeing was, with less anxiety and depression."

Jan 2, 2023 - Good hydration linked to healthy aging - NIH/NATIONAL HEART, LUNG AND BLOOD INSTITUTE
”Adults who stay well-hydrated appear to be healthier, develop fewer chronic conditions, such as heart and lung disease, and live longer than those who may not get sufficient fluids, according to a National Institutes of Health study published in eBioMedicine.
Using health data gathered from 11,255 adults over a 30-year period, researchers analyzed links between serum sodium levels – which go up when fluid intake goes down – and various indicators of health. They found that adults with serum sodium levels at the higher end of a normal range were more likely to develop chronic conditions and show signs of advanced biological aging than those with serum sodium levels in the medium ranges.”

Oct. 6, 2022 - Wear and tear from lifelong stress can increase cancer mortality - MEDICAL COLLEGE OF GEORGIA AT AUGUSTA UNIVERSITY
The wear and tear on the body from chronic and lifelong stress called allostatic load, refers to the cumulative effects of stress over time. “As a response to external stressors, your body releases a stress hormone called cortisol, and then once the stress is over, these levels should go back down,” says Dr. Justin Xavier Moore, epidemiologist at the Medical College of Georgia and Georgia Cancer Center. “However, if you have chronic, ongoing psychosocial stressors that never allow you to ‘come down,’ then that can cause wear and tear on your body at a biological level.” According to researchers, “Even when controlling for age, the researchers found that people with high allostatic load still have even 28% increased risk of dying from cancer.”

Sept 23, 2022 - Foot massage effective in improving sleep quality and anxiety in postmenopausal women - THE NORTH AMERICAN MENOPAUSE SOCIETY (NAMS)
"In this new, small-scale study, researchers specifically sought to evaluate the effects of foot massage on anxiety, fatigue and sleep in postmenopausal women.

April 28, 2022 - Seven hours of sleep is optimal in middle and old age, say researchers - University of Cambridge, UK
Researchers “… found that both insufficient and excessive sleep duration were associated with impaired cognitive performance, such as processing speed, visual attention, memory and problem-solving skills. Seven hours of sleep per night was the optimal amount of sleep for cognitive performance, but also for good mental health, with people experiencing more symptoms of anxiety and depression and worse overall wellbeing if they reported sleeping for longer or shorter durations.”

April 25, 2022 - A combination of three simple treatments may reduce invasive cancer risk by 61% among adults aged 70+ - Frontiers in Aging
"The participants were randomized into eight different groups to test the individual and combined benefit of the interventions: group one received 2,000 IU per day of Vitamin D3 (equivalent to > 200% the amount of current recommendations for older adults, which is 800 IU per day), 1g per day of omega-3s, and three times per week SHEP [simple home strength exercise program]; group two vitamin D3 and omega-3s; group three vitamin D3 and SHEP; group four omega-3s and SHEP; group five vitamin D3 alone; group six omega-3s alone; group seven SHEP alone; and the last group received a placebo." Results of the study found that when all three treatments were combined (vitamin D3, omega-3s, and the home exercise program), "...the benefits became statistically significant, and the researchers saw an overall reduction in cancer risk by 61%."

March 29, 2022 - Good hydration may reduce long-term risks for heart failure - NIH/National Heart, Lung and Blood Institute
”Staying well-hydrated may be associated with a reduced risk for developing heart failure, according to researchers at the National Institutes of Health. Their findings, which appear in the European Heart Journal, suggest that consuming sufficient amounts of fluids throughout life not only supports essential body functioning but may also reduce the risk of severe heart problems in the future.”

March 14, 2022 - Even moderate light exposure during sleep harms heart health and increases insulin resistance - Northwestern University
“Investigators found insulin resistance occurred the morning after people slept in a light room. Insulin resistance is when cells in your muscles, fat and live don’t respond well to insulin and can’t use glucose from your blood for energy. To make up for it, your pancreas makes more insulin. Over time, your blood sugar goes up.” Researchers also found that heart rate increases when sleeping in a moderately lit room.

March 4, 2022 - One alcoholic drink a day linked with reduced brain size - University of Pennsylvania
"…according to a new study, alcohol consumption even at levels most would consider modest—a few beers or glasses of wine a week—may also carry risks to the brain. An analysis of data from more than 36,000 adults, led by a team from the University of Pennsylvania, found that light-to-moderate alcohol consumption was associated with reductions in overall brain volume."

Jan. 26, 2022 - Vitamin D supplements lower risk of autoimmune disease, researchers say - Brigham and Women’s Hospital
Investigators found the people who took vitamin D, or vitamin D and omega-3 fatty acids had a significantly lower rate of AD [autoimmune diseases] than people who took a placebo.

March 19, 2021 - Study shows stronger brain activity after writing on paper than on tablet or smartphone - University of Tokyo
"Although volunteers wrote by hand both with pen and paper or stylus and digital tablet, researchers say paper notebooks contain more complex spatial information than digital paper. Physical paper allows for tangible permanence, irregular strokes, and uneven shape, like folded corners. In contrast, digital paper is uniform, has no fixed position when scrolling, and disappears when you close the app. 'Our take-home message is to use paper notebooks for information we need to learn or memorize,' said Sakai [corresponding author]."

March 17, 2021 - Eating before 8:30 a.m. could reduce risk factors for type 2 diabetes - Northwestern University

In a 2019, “For an eight-week study period, 36 volunteers from the Ann Arbor area agreed to have a nature experience for at least 10 minutes, at least three times a week.” University of Michigan researchers found that participants who spent a longer time period of 20 -30 minutes in nature had a lower measured stress hormone level.

 

Sept. 3, 2020 - How we sleep today may forecast when Alzheimer’s disease begins - UC Berkeley
”… researchers matched the overnight sleep quality of 32 healthy older adults against the buildup in their brains of the toxic plaque known as beta-amyloid, a key player in the onset and progression of Alzheimer’s, which destroys memory pathways and other brain functions and afflicts more than 40 million people worldwide. Their findings show that the study participants who started out experiencing more fragmented sleep and less non-rapid eye movement (non-REM) slow-wave sleep were most likely to show an increase in beta-amyloid over the course of the study." According to UC Berkeley neuroscientist Joseph Winer, “If deep, restorative sleep can slow down this disease, we should be making it a major priority,...”

Feb. 5, 2019 - Sleep Loss Encourages Spread of Toxic Alzheimer’s Protein - National Institutes of Health
"The new findings center on a protein called tau, which accumulates in abnormal tangles in the brains of people with Alzheimer’s disease. In the healthy brain, active neurons naturally release some tau during waking hours, but it normally gets cleared away during sleep. Essentially, your brain has a system for taking the garbage out while you’re off in dreamland. The latest findings in studies of mice and people further suggest that sleep deprivation upsets this balance, allowing more tau to be released, accumulate, and spread in toxic tangles within brain areas important for memory."
