New studies show a relationship between Alzheimer’s disease and a lack of deep sleep. Nap habits are a key.
Track Your SleepBoth Fitbit and the Apple Watch can help monitor your sleep habits. However, the battery life of Ionic, Versa and Charge 3 Fitbits can be measured in days, not hours, encouraging users to wear it at night, encouraging sleep tracking. “Our typical user is viewing sleep as being really important to their general wellness and mental health and how they handle stress and fatigue,” says Dr. Conor Heneghan, head of innovation and research at Fitbit Not that the Apple Watch isn’t a stellar health device. It can track sleep by using the heart rate monitor, but its 18-hour battery life means you need to take it off to charge it up. It also requires a third-party app to download data so that users can visualize the results. Fitbit sleep tracking is built into the device, just like step tracking, and you don’t have to set up or install anything additional. “We’re very interested in using the sleep tracking to then provide an additional service to alert people to a sleep apnea risk,” Heneghan said. “That’s where the battery life is important, because if you’re charging your device, you can’t be screening or detecting your sleep problems.” One way to avoid battery issues is to get a device specifically for sleep. The Oura ring slides on a finger at night and measures REM sleep, deep sleep, restlessness and other factors. However, some might be discouraged by its $299 and up price tag on a device that only measures sleep habits. Another downside to sleep tracking is that anxiety over results may actually make your sleep worse, not better. And while you may learn that sleep worsens after a glass or two of wine and improves on days you exercised, what do you do with the rest of the data? Experts recommend writing down your mood when you awaken, but before taking a look at device results, to better assess how your night’s rest has made you feel. Sleep Adaptogens: Botanicals To Relieve StressAdaptogens have long been used in Chinese medicine to help “balance” the body. They have to meet three criteria:
"The stress hormone, called cortisol, is our primary fight-or-flight hormone, and its release triggers an adrenal response causing physiological changes such as spikes in heart rate, blood pressure, and blood sugar,” according to Steven Zen, founder and CEO of Lokai, which has a line of adaptogen tonics. A spike in cortisol can lead to sleep disruption. Some of the better-known adaptogens for sleep include ashwagandaha, prized in Ayurvedic medicine for its healing power, and Holy Basil, which is thought to bestow tranquility. They are available in tablets, teas and more. |
It’s long been known that people with Alzheimer’s tend to have poor sleep. But scientists now think that that a lack of deep sleep may be a sign of the disease that appears long before cognitive symptoms are apparent.
"What's interesting is that we saw this inverse relationship between decreased slow-wave sleep and more tau protein in people who were either cognitively normal or very mildly impaired, meaning that reduced slow-wave activity may be a marker for the transition between normal and impaired," said first author Brendan Lucey, MD, an assistant professor of neurology and director of the Washington University Sleep Medicine Center. "Measuring how people sleep may be a noninvasive way to screen for Alzheimer's disease before or just as people begin to develop problems with memory and thinking.”
Studies show that amyloid beta protein starts to build plaque in the brain well before memory loss and confusion are evident. Tangles of tau appear after the plaque, but in advance of brain atrophy. While there is currently no cure for the disease, there are medicines that can slow its progression if it is discovered early.
