Your Digital Deadweight Brain

Research reveals how the Internet may be changing the brain,
NICM Health Research Institute, Western Sydney University, June 5, 2019.

MAIN POINTS

Cell Phonyism
"The key findings of this report are that high-levels of Internet use could indeed impact on many functions of the brain."

Stupid Phones
"...international team of researchers...have found the Internet can produce both acute and sustained alterations in specific areas of cognition, which may reflect changes in the brain, affecting our attentional capacities, memory processes, and social interactions."

Individual and Social Effects
"Instagramification of society"
"I believe that this, along with the increasing #Instagramification of society, has the ability to alter both the structure and functioning of the brain, while potentially also altering our social fabric."

Digital Hole
"It's clear the Internet has drastically altered the opportunity for social interactions, and the contexts within which social relationships can take place."

Coffee Reduces Death

Research suggests coffee consumption associated with reduced risk of death,
Institute for Scientific Information on Coffee, July 31, 2018.

Less Death for Coffee Drinkers
“...presented unpublished original research studying a cohort of almost 20,000 participants over an average of ten years...research suggests that coffee consumption at intakes of 3-6 cups of coffee a day reduces all-cause mortality. Within this cohort, there was a 22% lower risk of all-cause mortality for each two additional cups of coffee per day.”

Not Just the Caffeine
“...suggested that caffeine alone was unlikely to explain the effect on mortality, mentioning a potential role for polyphenols found in coffee, which may have antioxidant and anti-inflammatory effects.”

Less Death
“Meta-analyses have suggested that coffee consumption versus no coffee consumption is associated with an up to 17% risk reduction of all-cause mortality.”

Avalanche Victims: When can Rewarming Lead to Survival?
Eurac Research, May 28, 2019.

MAIN POINTS

"This study analysed the data relating to 103 avalanche victims admitted with cardiac arrest to seven major hospitals in Europe, between 1995 and 2016."

Two Types of Avalanche Deaths
"Of the 103 victims, 61 were rewarmed, but only 10 per cent survived; in the other cases it was not the hypothermia that caused the cardiac arrest, but suffocation during the avalanche or trauma."

The Survival Standard
Frozen or Suffocation Heart Stoppage?
"...hospitals require accurate guidelines based on significant evidence to justify extracorporeal rewarming using the heart-lung machine."

Survival Standards Found
"The factors that have emerged as decisive in this study are the core temperature and the concentration of serum potassium, the latter is related to cell degeneration. Using both these parameters, doctors can assess which patients have the potential to survive and which do not."

HEALTH & FITNESS

Running Young

Training for First-Time Marathon 'Reverses' Aging of Blood Vessels,
European Society of Cardiology, May 3, 2019.

MAIN POINTS

Running Young
"Training for and completing a first-time marathon "reverses" ageing of major blood vessels, according to research presented today..."

Four Years
"Novice runners who trained for six months and completed their first marathon had a four-year reduction in arterial age and a 4 mmHg drop in systolic blood pressure. This is comparable to the effect of medication, and if maintained translates to approximately 10% lower risk of stroke over a lifetime."

Potential
"Compared to their peers, lifelong athletes have biologically younger blood vessels. This study investigated whether training for a marathon could modify aortic stiffness even in novice runners."

Muscle Power & Protein Intake

 

1> POWER

Ability to lift weights quickly can mean a longer life,
European Society of Cardiology, April 12, 2019.

MAIN POINTS

“Prolong your life by increasing your muscle power.”

“...people with more muscle power tend to live longer.”

The Key: Power
“Power depends on the ability to generate force and velocity, and to coordinate movement.”

Power Forms
"Power training is carried out by finding the best combination of speed and weight being lifted or moved. For strength training at the gym most people just think about the amount of weight being lifted and the number of repetitions without paying attention to the speed of execution. But for optimal power training results, you should go beyond typical strength training and add speed to your weight lifts."

HEALTH & FITNESS NEWS: Dangers of High Intensity Exercise

 

HEALTH & FITNESS

High Intensity Exercise

High-intensity interval training increases injuries, Rutgers study finds,
Rutgers University, April 9, 2019.

MAIN POINTS

Interval Training
"These workouts, which combine aerobic exercising, weight lifting and calisthenics at maximum capacity, followed by periods of recovery, have been growing in popularity over the past decade, driven by the efficiency of the exercise to deliver fitness goals in less time."

DANGER
"People who engage in high-intensity interval training are at greater risk for injury, especially in the knees and shoulders."

Effective but Dangerous
"...acknowledged that while this type of training is effective in improving cardiorespiratory fitness, boosting energy and promoting lean muscle mass and fat loss, it also increases injury risk."

Why
Improper Prep
"...many athletes, especially amateurs, do not have the flexibility, mobility, core strength and muscles to perform these exercises."

Exercise has Anti-Inflammatory Effect Preventing Osteoarthritis Cartilage Damage

 

HEALTH & FITNESS

Exercise has Anti-Inflammatory Effect

Exercise helps prevent cartilage damage caused by arthritis,
Queen Mary University of London, March 27, 2019.

MAIN POINTS

Exercise Good
“Exercise helps to prevent the degradation of cartilage caused by osteoarthritis...”

Movement is Anti-Inflammatory
“During exercise the cartilage in joints such as the hip and knee is squashed. This mechanical distortion is detected by the living cells in the cartilage which then block the action of inflammatory molecules associated with conditions such as arthritis.”

“…this is down to tiny hair-like structures called primary cilia found on living cells.”

Why
“...this anti-inflammatory effect of physical activity is caused by activation of a particular protein, called HDAC6, which triggers changes in the proteins that form primary cilia.”

Waste Treatment Plants: Antibiotic Resistance Factories

A 'Post-Antibiotic World?'
University of Southern California, March 5, 2019.

MAIN POINTS

Recycling Resistance
“The products of wastewater treatment have been found to contain trace amounts of antibiotic resistant DNA. These products are often reintroduced to the environment and water supply, potentially resulting in the spread of antibiotic resistance.”

Next Destination
"We're quickly getting to a scary place that's called a "post-antibiotic world," where we can no longer fight infections with antibiotics anymore because microbes have adapted to be resilient against those antibiotics."

Engines of Antibiotic Destruction
"Unfortunately, engineered water treatment systems end up being sort of a hot-bed for antibiotic resistance."

Biological Filters
“...one of the common ways in which the wastewater is treated is with a membrane bioreactor, which uses both a filtration system and a biological process where microscopic bacteria consume waste products.”

Training Beyond Exhaustion can Prevent Learning

HEALTH & FITNESS RESEARCH

Don’t Over-train

Training beyond exhaustion can prevent learning,
eLife, March 5, 2019.

MAIN POINTS

Over-training
"...we set out to disentangle the effects of fatigue on performance of a task from its effects on the ability to learn and get better at it."

Hurts for Days
"...muscle fatigue caused by overexertion when practicing a skill can affect the task in hand and impair learning afterwards."

Pinch Test
“The researchers asked 120 people to learn a pinch-force task over two days.”

"...they found that those people who had reached the point of exhaustion performed less well using both their fatigued and unfatigued hands.

I’m Tired
"This suggested that fatigue impairs motor skill learning mechanisms in the brain."

“...fatigue may affect the formation of memories that help people to retain new skills they have learned.”

Overtraining Bad
“We have shown that learning in a fatigued state results in detrimental effects on a person’s ability to acquire a new skill.”
