When I leave for work in the morning, I go through my precommute checklist. Train pass, check. Wallet, check. Coffee mug, check. Smart phone, check. Keys to the house, check. Only when I’m sure that I have everything I need do I open the door and head outside.
Sometimes I worry that this morning routine is becoming too much of a ritual. Is it possible that I have obsessive-compulsive disorder (OCD for short)?
Probably not. The fact that I am able to get out the door every morning means that my daily ritual isn’t interfering with my ability to function, says Dr. Jeff Szymanski, a clinical instructor in psychology at Harvard Medical School.
You have OCD when obsessions and compulsive behavior Read more »

As if people with the combination of high blood pressure and heart disease don’t already have enough to worry about, a new study suggests that common painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs) pose special problems for them.
Among participants of an international trial called INVEST, those who often used NSAIDs such as ibuprofen (Advil, Motrin and others), naproxen (Aleve, Naprosyn, and others), or celecoxib (Celebrex) were 47% more likely to have had a heart attack or stroke or to have died for any reason over three years of follow-up than those who used the drugs less, or not at all. The results were published in the July issue of the American Journal of Medicine.
Millions of people take NSAIDs to relieve pain and inflammation. They are generally safe and effective. The main worry with NSAIDs has always been upset stomach or gastrointestinal bleeding. During the last few years, researchers have raised concerns that Read more »

It doesn’t make sense: If sunlight causes cancer, why are human beings so drawn to it, flocking to sunny beaches for vacation time and hoping for sunshine after a rainy spell?
One answer, says David Fisher, chief of dermatology at Harvard-affiliated Massachusetts General Hospital in Boston, may be that humans are literally addicted to sunshine so our skin can make vitamin D. New evidence suggests that we get the same kick out of being in the sun that we get from any addictive substance or behavior. It stimulates the so-called “pleasure center” in the brain and releases a rush of feel-good chemicals like endorphins.
So there may be more than a desire to look good in a tan behind the urge to soak up the sun’s rays. This craving may be a survival mechanism that evolved over thousands of years because humans need vitamin D to survive. Skin makes this crucial vitamin when it is exposed to sunlight. There isn’t much vitamin D in food (except in some of today’s fortified foods) so the human brain rewards us with a rush of pleasure when we seek out the sun and get vitamin D.
Seeking sunshine can be downright dangerous. As Fisher points out, Read more »

Feeling tired? If so, it’s not surprising. Fatigue is one of the most common problems people report to their doctors. The Health and Retirement Study of more than 17 million older people ages 51 and up reported recently that 31% said they feel fatigued.
Fatigue is a symptom, not a disease. Different people experience it in different ways. The tiredness you feel at the end of a long day or after a time zone change might feel similar to that resulting from an illness. But fatigue from stress or lack of sleep usually subsides after a good night’s rest, while disease-related lethargy is more persistent and may be debilitating even after restful sleep.
Finding the cause. How do you know if your low-energy is caused by an underlying illness or is the result of stress, poor diet, or lack of sleep? For example, could you have chronic fatigue syndrome? That is an unusual illness and an uncommon cause of persistent fatigue, says Anthony Komaroff, M.D., professor of medicine at Harvard, world-renowned expert on chronic fatigue syndrome, and medical editor of a new Harvard Special Health Report, Boosting Your Energy. About 4 to 8 of every 1,000 adults in the United States suffer from chronic fatigue syndrome, which is about twice as common in women as in men. The causes of chronic fatigue syndrome are still unknown, and there is no accurate diagnostic test. However, scientists have found abnormalities in the brain and peripheral nervous system, in the immune system, and in energy metabolism in people with this syndrome. Read more »

If you are a smoker, or love someone who smokes, the specter of lung cancer is ever looming. Wouldn’t it be great if there was a way to detect lung cancer in its earliest and most curable stages, much like the goal of mammograms for breast cancer?
Although it seems like common sense to do such advance checks—a process called lung cancer screening—studies to date haven’t shown that finding lung cancer early translates into fewer deaths from the disease.
A new report in the New England Journal of Medicine suggests that screening heavy smokers with yearly low-dose CT scans can reduce deaths from lung cancer by 20% compared to screening with chest x-rays. The results are from the National Lung Screening Trial, which included more than 53,000 current and former heavy smokers between the ages of 55 and 74. (Preliminary results from this trial were covered in the Harvard Health Letter and in the Harvard Health blog.) Read more »
