Sleeping

Scientists have designed a smart mattress designed to tap into the body's circadian rhythms, carefully heating and cooling different areas to coax you into a deep slumber, with some promising results from an early trial.

A new study suggests brain inflammation is the key factor linking sleep disturbances with Alzheimer’s disease. It's hypothesized the same overactive immune cells in the brain that contribute to cognitive decline can disrupt certain sleep cycles.

Does insomnia directly increase a person’s blood sugar? A new study suggests it does, and proposes treating insomnia in diabetic patients could lead to significant improvements in their disease symptoms.

Napping for more than an hour a day could be an early sign of Alzheimer’s disease according to new research. It’s suggested excessive daytime napping shares a bidirectional relationship with dementia, reflecting and shaping changes in the brain.

Do you thrive on between four and six hours of sleep per night? You may be an “elite sleeper,” and a new study reports the same genes associated with short sleep patterns may also slow the onset of brain diseases such as Alzheimer’s.

Researchers have found sleeping in a moderately lit room can potentially harm a person’s cardiometabolic health. The study saw one night of sleep in a room with moderate light increased nighttime heart rates and spiked insulin resistance in the morning.

What is your pre-bedtime routine? Across a series of robust mouse experiments a new study is shedding light on what goes on in the brain before sleep and how those pre-sleep behaviors directly activate parts of the brain that help initiate sleep.

Sleep is a crucial biological phase, but exactly why almost every organism needs it remains mysterious. Now a study has uncovered a new piece of the puzzle, finding that a protein involved in DNA repair signals the brain when it’s time to sleep.

A long-term observational study is reporting a link between short sleep durations in midlife and increased risk of dementia in old age. The research cannot offer evidence of a causal link but it is one of the longest studies to detect this association.

More than one in 10 adults suffer from chronic rhinosinusitis, an inflammatory sinus condition. A new brain imaging study suggests the disease is linked with functional brain connectivity changes that could explain cognitive problems such as brain fog.

A new observational study is building on a body of data finding a correlation between afternoon naps and improved mental agility. The research hypothesizes afternoon naps may help moderate age-related neuroinflammation helping keep the brain healthy.

A new observational study, analyzing data from nearly half a million UK subjects, suggests improving sleep behavior is an important intervention for both clinicians and patients looking to reduce risk of heart failure.
