Testosterone May Impair Sleep

Men with many things to keep0199210896.testosterone.1 them up at night can add another suspect to the list: testosterone. Researchers at the University of Chicago Sleep, Metabolism and Health Center evaluated the sleep of 44 men, all of whom were overweight or obese, but otherwise healthy.  A news release from the Endocrine Society reports that the researchers studied the brain’s slow-wave activity during non-rapid eye movement sleep, a reliable marker of sleep depth. Too little slow-wave activity can leave a person feeling unrested in the morning. To their surprise, the researchers found that a person’s BMI had no influence on slow-wave activity, but testosterone did. The big concern? As doctors increasingly prescribe testosterone to aging men, they may increasingly be interfering with a good night’s sleep.

    The observation of an inverse relationship between testosterone (T) and slow-wave deep sleep (SWS) is interesting to me both personally and professionally (retired sleep disorders specialist). Personally, I have monitored my own sleep at home each night for many years and have observed dismally low levels of SWS. It is well documented that SWS does decrease with advancing age, however so does T in most men. Although I am now in mu early 70s I am in very good health and run road and trail races and also Mt. Bike. My T levels, probably as a result of my exercise regimen are at the top of the charts for my age, or indeed at any age. So now I have new understanding as to why my SWS is low. The question I now have is why an inverse relationship between SWS and T? In the sleep literature SWS is viewed as restorative and one would think that I would need a lot of restorative sleep to repair stressed muscles from exercise workouts of running long distance and Mt. biking. Indeed, recovery from muscle soreness takes longer in aging runners and bikers so that fits with the decline in SWS, but then the question is why does regular, intense exercise pump up TST? I always thought that was a good thing but now, armed with this new information, I am beginning to wonder.

    High-Intensity Training Best For Endurance

    It seems counterintuitive, but short bursts of high-intensity training appear to do more for endurance than running a marathon does. The Wall Street Journal reports on the research supporting the claim, which was conducted at the Karolinska Institute in Stockholm, where researchers asked 50 men to cycle as fast as possible for 30 seconds, rest for four minutes and then repeat the exercise six times. They then collected muscle tissue samples from the cyclists’ thighs, and looked for evidence of […]

    Extreme Exercise Could Be Bad For Your Heart

    Extreme exercise, such as running more than 35 miles a week or biking more than 150 kilometers a week, could increase levels of coronary artery calcium–a bad thing. The Wall Street Journal reports on a recent study conducted by British physicians that looked at the cardiac health of 169 serious endurance athletes. Forty-one men and 16 women in the group ran more than 35 miles or cycled more than 150 kilometers a week. The researchers found that, compared with the […]

    How Many Marathons Should You Run In A Year?

    For years, the Wall Street Journal tells us, most marathoners thought it wise to limit the number of races run per year to two. Now, however, comes a new school of thought that suggests that running more could be just fine, and good for your finish time. The paper reports that so far in 2015, 15.8 precent of marathon finishers in races tracked by the Active Network ran more than one marathon this year, compared with just 2.3 percent in […]

    For Dislocated Shoulder, Just Say No To Surgery

    Yes, shoulder dislocations hurt. So does recovery from the surgery that often follows dislocations. Now comes a study from St. Michael’s Hospital in Toronto suggesting that surgery can do more harm than good, by prolonging the recovery period from a shoulder dislocation. Researchers at the hospital studied the progress of 83 patients who suffered moderate or severe shoulder dislocations. Some patients received either plate-and-screws surgery followed by rehabilitation and others had non-surgical treatment with sling and rehabilitation. Ready? the envelope […]

    How To Uncramp A Cramped Muscle

    Cramped muscles, as New York Times health columnist Gretchen Reynolds tells us, were long thought to result from dehydration. Not anymore. That supposition was disproved when tests showed that it takes the same amount of small electric shocks administered to muscles of athletes who were dehydrated and athletes who were not to stimulate a cramp. What then does cause a muscle to cramp? Reynolds says recent research suggests that it’s  nerve endings that are overexcited, paradoxically, because they’re tired. What to […]

Not so good, according to researchers at the University of Utah, who followed more than 200 people with recent-onset low back pain who were randomly assigned to physical therapy or no treatment for the first month after their pain began. HealthDay reports that three months in, the researchers did notice some modest improvement in the ability to move among those who did physical therapy, which included back manipulation and exercise, but after a […]

    Beer After A Workout? Possibly, With Care

    Is drinking a beer after a dehydrating workout a good idea or a bad idea? According to the Wall Street Journal, it depends. The Journal quotes Jim White, owner of Jim White Fitness & Nutrition Studios in Virginia Beach, Va., advising us that, while the body needs carbs after a workout, beer, with only 14 grams of carbs per beer, is not best provider. White says a hard workout is best followed with water, or with drinks with a carbs-to-protein ratio of […]
