Home sleep tests are often the preferred approach to detect obstructive sleep apnea. They use less equipment and cost less than studies done in sleep labs. Because people get to conduct the test in their own beds, they are more comfortable than they would be in a sleep lab, and the test is more likely to capture a person's natural sleep habits. But the tests aren't always accurate. And someone with a serious chronic condition, such as heart failure or a breathing disorder, might need additional data from an in-lab study.

Sleep problems such as insomnia, sleep apnea, and periodic limb movements can disrupt sleep. A lack of sleep or fragmented sleep can prevent people from getting enough restorative deep sleep and may cause unhealthy blood pressure surges. These problems may increase the risk of cerebrovascular disease (including stroke and unrecognized silent strokes) and cognitive issues.

Cannabidiol (CBD) is an active ingredient in cannabis that is derived from the hemp plant, but it does not cause a high and is not addictive. CBD has been shown to be effective in treating conditions like pain, insomnia, and anxiety.

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.

A 2023 study suggests that women who prefer to stay up and wake up later are more likely to develop diabetes and to have unhealthful lifestyle habits compared with those who prefer to go to bed and wake up earlier.

Fatigue is a common symptom that can be caused by a whole host of factors, from medical conditions to stress and poor sleep. In order to ease ongoing fatigue, it's important to investigate and treat the underlying cause. Fatigue that doesn't respond to interventions or is severe or persistent should be brought to the attention of a doctor. It may be caused by a medical condition.

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.

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.

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.
