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.

  • Seems prescriptions (testosterone)given to geezers to help them keep it up is keeping them up.

    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.

A Carnegie Mellon news release reports that the researchers surveyed 404 healthy people, asking them about personal conflicts and the number of hugs they received over a 14-day period. The people were then exposed to a common cold virus, […]

    When can you stop weighing yourself? Whenever you want to, but if you really want to keep losing weight, it’s best to weigh-in at least once a week. That’s the conclusion of researchers at Cornell University’s Food and Brand Lab, where scientists analyzed 2,838 weight measurements (up to a years’ worth of weigh-ins) from 40 overweight people who were trying to lose weight.  A Cornell news release reports that the researchers found that the more frequently people weighed in, the more […]

    Where Exactly Does The Fat Go?

    When you lose weight, where does the fat go? Don’t ask your doctor: new research at the University of New South Wales suggests that more than 50 percent of doctors think it’s converted to energy. Wrong. The correct answer is into the air, breathed out as carbon dioxide. A UNSW news release reports that losing 10 kilograms (22 pounds) of fat requires 29 kilograms (64 pounds) of oxygen to be inhaled and that this metabolic process produces 28 kilograms (62 pounds) […]

    Irregular Heartbeat Treatment Improved By Exercise, Diet

    Atrial fibrillation–doctors know it as AF,  you know it a disturbing irregular heartbeat–can be bad for your health. It is usually remedied with a procedure called catheter ablation, in which electricity is used to burn the tissue around the problem area. Strange, but it works, somewhat. Now comes a study from researchers at the University of Adelaide suggesting a way to greatly improve the likelihood that it will continue to work. A U of Adelaide news release reports that researchers at […]

HealthDay reports on research conducted at Harvard Medical School that analyzed the results of a clinical trial of nearly 28,000 women who were largely healthy and relatively young — about 55 years old, on average at the start of the study, and were randomly assigned to take low-dose (100 mg) aspirin or […]

    It’s true that this study didn’t find an association between running and getting Alzheimer’s, but that’s because the researchers didn’t look for one. What they did look for was an association between running and death from Alzheimer’s, and they found a big one: people who ran more than 15.3 miles a week had a 40 percent risk reduction in death from Alzheimer’s, and those who ran between 7.7 and 15.3 miles had a 25 percent risk reduction.

    Yes, in addition to its folkloric power to deter evil spirits, garlic may slow the spread of some cancers, including prostate, melanoma, and some types of leukemia, all of which weaken the body by over-activating the natural immune system. A University of Copenhagen news release reports that researchers at the school have found that selenium, which is found in garlic and broccoli, slows down the immune over-response, which may improve cancer treatment. How? It’s complicated, but here we go: The immune system […]

It could be good news, except the Times also reports that excessive drinking, the kind practiced by non-alcoholics as well as alcoholics, results in 88,000 deaths a year, from causes that include alcohol poisoning and […]
