Researchers at the University of Tsukuba in Japan show that low metabolic flexibility is associated with reduced fat metabolism during sleep.

Researchers from the University of Tsukuba and Kyoto University find that capillary blood flow in the brain, which is important for delivering oxygen and nutrients and removing waste products, is increased in mice during the dream-active phase of sleep.

Researchers from University of Tsukuba in collaboration with Yamagata University scientists find that exposure to light with less blue before sleep is better for energy metabolism. Extended exposure to light during nighttime can have negative consequences for human health. But now, researchers from Japan have identified a new type of light with reduced consequences for physiological changes during sleep.

Researchers from the University of Tsukuba find that vigorous exercise causes imperceptible improvements in sleep quality Tsukuba, Japan—Physical exercise has long been prescribed as a way to improve the quality of sleep. But now, researchers from Japan have found that even when exercise causes objectively measured changes in sleep quality, these changes may not be subjectively perceptible. In a study published this month in Scientific Reports, researchers from the University of Tsukuba have revealed that vigorous exercise was able to modulate various sleep parameters associated with improved sleep, without affecting subjective reports regarding sleep quality.

Researchers from the University of Tsukuba have discovered a group of neurons in the mouse brainstem that control muscle tone. Inhibiting these neuronal cells caused mice to move during REM sleep, reminiscent of REM sleep behavior disorders. These neurons were also responsible for episodes of cataplexy in a mouse model of narcolepsy; inhibiting them reduced the number of cataplexic bouts. These circuits could thus be a new target for treating these sleep disorders.

Researchers led by the University of Tsukuba find that drinking two cups of oolong tea a day can stimulate fat breakdown while you sleep.

Researchers at WPI-IIIS find that normal sleep in mice depends on bacteria that help make neurotransmitters such as serotonin in the gut. The article, “Gut microbiota depletion by chronic antibiotic treatment alters the sleep/wake architecture and sleep EEG power spectra in mice,” was published in Scientific Reports.
