Moderate Drinking Boosts Immune System

December 18, 2013 8:07 am 1 comment

First, nimagesote well the word “moderate,” because immoderate drinking does to your immune system what water in the gas tank does to your car. Researchers at Oregon Health & Science University (I know, you never heard of it) are convinced that moderate drinking boosts the immune system, at least in monkeys. A university news release reports that researchers trained a group of 12 rhesus macaques, who were vaccinated against small pox, to consume alcohol — a 4 percent ethanol mixture whenever they felt like it. They then separated the animals into two groups — those with access to the 4 percent ethanol and those with access to sugar water. All of the animals had regular access to pure water, and to food. The researchers monitored the animals’ alcohol intake for 14 months, and segregated them into two groups- heavy drinkers, those that had an average blood ethanol concentration greater than 0.08 percent — the legal limit for humans to be able to drive a vehicle; and moderate drinkers, with an average blood ethanol concentration of 0.02 to 0.04 percent. And now the news: Prior to consuming the alcohol, all of the animals showed comparable responses to the vaccination. But after exposure to the alcohol, the two groups of monkeys responded in very different ways to the vaccination. The heavy drinkers showed greatly diminished vaccine responses compared with the control group of monkeys who drank the sugar water. But the moderate-drinking monkeys showed enhanced responses to the vaccine compared to the control group. Moderate drinking bolstered their bodies’ immune systems.

    Massage may be another pleasure of the pampered class, but unlike some other pleasures, it does some serious good. How do we know? Because researchers at the University of Illinois at Chicago asked 36 healthy young adults to use a leg press machine until their legs became sore, then gave half the group a Swedish leg massage, and had all of the participants rate their muscle soreness on a scale from one to 10. A third comparison group didn’t exercise, […]

    Get Used To It: Decline Begins At 24

    By now, if researchers at Simon Fraser University are correct, most SportsGeezer readers have been getting a little slower and a little less sharp for decades. Yes, decades. In fact, based on an analysis of digital performance records of 3,305 StarCraft 2 players aged 16 to 44, researchers have concluded that our cognitive performance starts going downhill at age 24. The good news for those who are well past 24? “Older players, though slower, seem to compensate by employing simpler […]

Is that a lot? Well, mice that ingested green tea extract but did not exercise or those […]

    Forget “Don’t get angry, get even.” Try “Don’t get angry and spare yourself a heart attack.” The New York Times reports on research conducted at Harvard Medical School suggesting that in the two hours after an outburst of anger, the risk of angina and heart attack increases by nearly five times, while the risk of ischemic stroke and cardiac arrhythmia increases by more than three times. The researchers got there by combining data from nine studies of anger outbursts among […]

    Are you worried that your forgetful senior moments are an indicator of things to come? Forget about it. That’s the advice from researchers at the Institute of Primary Medical Care in Kiel, Germany, where a recent three-year-long study of people with mild cognitive impairment found that 42 percent returned to normal mental function, 36 percent retained their mild impairment and only 22 percent developed dementia.  HealthDay reports that the study found that 21 percent of participants fluctuated between mild cognitive impairment […]
