Update on atrial fibrillation

New guidelines for managing atrial fibrillation focus on lifestyle habits to prevent and control the disorder. One recommendation is for people to limit alcohol to one drink per day, or ideally less. Another is for people who are overweight or obese to lose weight, either by striving for a body mass index no greater than 27 or by shedding at least 10% of their body weight. The guidelines also suggest that people get three to four hours of exercise per week. And people with afib who snore should consider getting tested for sleep apnea.

Night owls may face higher diabetes risks

Fighting fatigue

Fatigue is a common symptom that can be caused by a whole host of factors, from medical conditions to stress and poor sleep.

Our internal clocks regulate the sleep-wake cycle, and light establishes when we should feel wakeful or sleepy. Light exposure at night affects these natural processes, so researchers studied whether wearing an eye mask while sleeping might help learning and alertness.

Ovary removal before menopause may pose health risks

A 2023 study suggests that women who have both ovaries removed before menopause face higher odds of several health conditions, including arthritis, sleep apnea, and bone fractures.

Bad bedfellows

The use of sleep tracking devices is increasing, but using a sleep tracker can contribute to anxiety and insomnia. Data from the device can influence how a person feels after awakening, even if the data aren't accurate. Sleep trackers can make people more aware of their sleep patterns and potentially help identify sleep disorders, but the data generated can be confusing and lead people to ignore how they feel after sleeping. A special form of cognitive behavioral therapy called CBTi is designed to improve insomnia and anxiety around sleep.

Poor sleep linked to next-day episodes of atrial fibrillation

When people with atrial fibrillation sleep poorly, they may be more likely to have an episode of atrial fibrillation the next day, according to a 2023 study.

Tips to navigate a "sleep divorce"

Some couples find that sleeping in separate rooms helps them get a better night's sleep. But before trying it, it's important to consider compromises to stay in the same room. For example, if one person snores, a doctor visit might be in order, and the other person might try wearing earplugs to better tolerate the sound. If separate bedrooms are the answer, it helps to make both sleeping spaces cozy, schedule time for intimacy, and regularly assess whether the arrangement is working for both partners.

Poor sleep linked to high blood pressure
