During waking hours you may feel your heart rate fluctuating, and activity or intense emotions can cause it to spike. But what happens to your heart rate when you sleep? It varies then too, depending on the phase of sleep you are in.
Researchers measuring activity levels found that people who tend to go to bed later and sleep later also tend to get less physical activity, compared to early risers. However, these results don’t mean that being a night owl is the cause of getting less activity, or that such behavior can’t be changed.
It’s well known that getting enough sleep is critical to daily functioning and long-term health. Now, new research suggests that a lack of enough REM sleep may be related to earlier death in people at middle age or older.
Back-to-school plans are still a question mark for many school districts, and it’s probably tempting to let a more relaxed summer sleep schedule stay in place. But consistency and routine are important for children and teens to ensure they get enough high-quality sleep. Here’s how to create that structure.
Sleep apnea robs people of high-quality sleep, increases the risk of heart problems, and puts people at higher risk of accidents. While an overnight stay in a sleep lab used to be required to diagnose sleep apnea, now this testing often can be done at home.
Many lifestyle factors can influence the development of atrial fibrillation, and doctors now better understand the importance of these factors in treating afib. Those who are at risk of developing afib can take action to improve their health, and in some cases they may be able to reduce their symptoms.
Many people with sleep apnea find that a CPAP machine helps them, but others struggle and have difficulty using a CPAP machine. There are many reasons this could be happening, and it’s important for people to work with their doctor to troubleshoot and try adjustments that can make using the machine easier and more effective.
Obstructive sleep apnea affects an estimated 20% of the population, and if untreated it has negative effects on cardiac and metabolic health as well as quality of life. If the condition is moderate or severe, a CPAP machine is the first-line treatment, but there is less consensus about treatment of mild OSA.
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.
Millions of Americans have trouble sleeping, a factor that is key to cardiovascular health. Two recent studies examined the relationship between sleep and heart health, and between sleep and dietary choices.
