The Brain-Sleep Connection: GCBH Recommendations on Sleep and Brain Health
A new report from the Global Council on Brain Health (GCBH) gives tips and recommendations on sleep to help maintain and improve brain health.
If you want to maintain your brain health as you age, then get the recommended seven to eight hours of sleep per day, according to a new consensus report issued today by the GCBH. The expert recommendations include a wealth of information and practical tips for all adults aged 50-plus to improve and maintain healthy sleep habits.
A recent AARP consumer survey found that 99% of adults age 50-plus believe that sleep is important for their brain health, but over four in 10 (43%) say they don’t get enough sleep. More than half (54%) of adults report they wake up too early in the morning and can’t get back to sleep.
“We know how many questions adults have about how much sleep is enough, and the role that sleep plays in brain health and cognitive function,” said Marilyn Albert, Ph.D., GCBH Chair, Professor of Neurology and Director of the Division of Cognitive Neuroscience at Johns Hopkins University in Baltimore, Maryland. “This report answers a lot of these questions and we hope it will be a valuable source of information for people.”
The new recommendations cover a wide range of sleep-related issues, including common factors that can disrupt sleep, symptoms of potential sleep disorders, and prescription medications and over-the-counter (OTC) sleep aids. A host of helpful expert tips are also included in the report, such as ways to help fall asleep or stay asleep, when to seek professional help for a possible sleep disorder, and the pros and cons of napping.
Based on the scientific evidence, the GCBH made the following consensus statements:
- Sleep is vital to brain health, including cognitive function, and sleeping on average 7-8 hours each day is related to better brain and physical health in older people.
- The sleep-wake cycle is influenced by many different factors. A regular sleep-wake schedule is related to better sleep and better brain health. Regular exposure to light and physical activity supports good sleep.
- People, at any age, can change their behavior to improve their sleep.
- Persistent, excessive daytime sleepiness is not a normal part of aging.
- Sleep disorders become more common with age, but can often be successfully treated.
- People with chronic inadequate sleep are at higher risk for and experience more severe health problems, including dementia, depression, heart disease, obesity and cancer.
The GCBH have also included in their report a range of practical tips and recommendations on sleep to help maintain and improve brain health:
- Get up at the same time every day, seven days a week.
- Restrict fluids and food three hours before going to bed to help avoid disrupting your sleep to use the bathroom.
- Avoid using OTC medications for sleep because they can have negative side-effects, including disrupted sleep quality and impaired cognitive functioning.
- Dietary supplements such as melatonin may have benefits for some people, but scientific evidence on their effectiveness is inconclusive. Be particularly cautious of melatonin use with dementia patients.
- Avoid long naps; if you must nap, limit to 30 minutes in the early afternoon.
