In search of sleep
Many women making the transition to menopause have trouble sleeping. Several strategies can help you get the rest you need.
If you're a woman of a certain age and you often find yourself staring at the ceiling in the middle of the night, you're not alone. The years leading up to menopause and the period that immediately follows are the times that women are most likely to report problems sleeping, according to the National Sleep Foundation. Many different conditions that are common in this stage of life — including hot flashes, obstructive sleep apnea, and mood disorders such as depression or anxiety — can cause sleep problems.
Lack of sleep is more than just a nuisance. "We now understand that high-quality sleep is absolutely vital to good health," says Dr. JoAnn E. Manson, the Michael and Lee Bell Professor of Women's Health at Harvard Medical School. This means that seeking care should be a priority if you are experiencing problems.
Why your sleep and wake cycles affect your mood
The body’s circadian rhythm controls our sleep-wake cycle, so an irregular rhythm can negatively affect sleep and proper functioning, which can lead to health problems including mood disorders. The tendency to rise early or stay up late is genetically determined, but you may be able to adjust your life to better match your circadian rhythm.
5 ways to prevent a heart attack
These are the most effective ways to protect yourself.
Here are some alarming statistics about heart attacks:
- Every 40 seconds, someone in the United States has a heart attack.
- Every year, about 805,000 Americans have heart attacks, 75% of which are first-time attacks.
- The average age of a first heart attack among men: 65.
However, the most troubling fact about heart attacks is that many people don't take steps to protect themselves, says Dr. Deepak L. Bhatt, executive director of interventional cardiovascular programs at Harvard-affiliated Brigham and Women's Hospital Heart & Vascular Center. "Reducing your risk of cardiovascular disease is the best way to guard against heart attacks," he says. "There are simple ways to do this, but unfortunately, many people still don't follow them as they should."
Here's a look at five ways you can protect yourself from cardiovascular disease, and thus possible heart attacks, and avoid being another statistic.

Older adults and medical marijuana: Reduced stigma and increased use
Cannabis use among older adults has been steadily increasing, due to lessening stigma and increased interest in using medical marijuana. But there are specific concerns for older people, so anyone considering this option should have a conversation with their doctor weighing the benefits and risks.
Strategies to promote better sleep in these uncertain times
5 steps to long-lasting independent living
Here's how to maintain your current active lifestyle.
Older adults want to enjoy their independent living as long as possible. Yet this can become a challenge as people face more health issues.
"Most life changes that cause older adults to lose some or all of their independence occur either gradually or suddenly," says Dr. Jennifer Rhodes-Kropf, a primary care geriatrician at Harvard-affiliated Hebrew SeniorLife's Center Communities of Brookline, Mass. "You need to stay on top of critical areas that can jeopardize your health and lifestyle."
Too early to get up, too late to get back to sleep
Sleep-maintenance insomnia common complaint among women at midlife
You wake up and look at the clock: it's 3 a.m. You tell yourself you've got to get back to sleep, but thoughts about yesterday's troubles, the coming day's challenges, and all those "must-do's" race through your mind. You toss and turn and worry about not getting enough sleep. Maybe you doze off for an hour or so, but when the alarm clock gets you up for the day, you're far from rested.
Insomnia — inability to get the sleep you need to wake up refreshed — is the most common sleep complaint in the United States. It often takes the form of sleep-maintenance insomnia — that is, difficulty staying asleep, and in particular, waking too early and struggling to get back to sleep. Like difficulty falling asleep at the beginning of the night, called sleep-onset insomnia, sleep-maintenance insomnia is more common in women than in men.
What is inflammation, and why is it dangerous?
Ask the doctors
Q. I've heard a lot recently about inflammation being a health risk, but I'm not sure I really understand what it is. Can you explain?
A. When people talk about inflammation, they're actually talking about your immune system's response to a perceived injury or infection. When you're injured, this inflammation is actually a good thing. The area you injured will become red and swell as an army of beneficial white blood cells flow in to fight infection and help you heal. The same response occurs in other parts of your body when you encounter a virus or infection. But sometimes this immune response occurs when it shouldn't. It can be triggered, for example, when you are exposed to toxins, and by other causes such as chronic stress, obesity, and autoimmune disorders. In these cases, instead of moving in, healing the problem, and then returning to normal, the inflammation persists over time. It's thought that this chronic state of inflammation can lead to numerous health problems, including heart disease, arthritis, depression, Alzheimer's disease, and even cancer.
