There is a recent story [March 05, 2025], OHSU sleep scientists provide tips for springing ahead, stating that, “Ahead of the time change on Sunday, experts say small steps can ease the transition. Shift ahead of time. McHill said now is the time to begin shifting internal clocks to go to sleep and wake up a little earlier, so that it’s not such a dramatic shift when the alarm clangs for work or school on Monday morning. Adjust diet: McHill co-authored a study published last year that compared people eating high-fat and low-fat diets, and found that those eating a low-fat diet were better able to adapt to the time change. Give yourself grace: The body will adjust over the next week or so, but McHill said it’s important to recognize that it will take time to adjust. “Recognize that on Monday morning, things are going to be a little harder,” he said. “Just know that you may be running a little slower than normal and take some time to ease into the new schedule.””

March 10-16 is Brain Awareness Week for 2025.
Sedona, AZ — It is possible to have AI chatbots provide categorizations to shape the relationship of individuals with sleep. Why is sleep important? What is asleep? Why does good sleep feel refreshing? What makes sleep sometimes easier after fatigue? What should be understood about sleeplessness?
These are not questions for obvious answers like sleep is for rest, or others, but to explore conceptual brain science, for the foundation of sleep by the human mind. It is theorized that the human mind is the collection of all the electrical and chemical signals, with their interactions and attributes, in sets, in clusters of neurons, across the central and peripheral nervous systems. Simply, the human mind is the set of signals.
This means that every function has a set of signals responsible for regulation, interpretation, experience and information organization. For sleep, functions can be roughly categorized into two: external senses and internal senses.
It can be assumed that external senses are mostly closed [or distribution drops of electrical signals] during sleep. This means that the senses of touch, smell, sight, sound, and taste are not as available as when [an individual is] awake. However, internal senses like respiration, circulation, and several others continue to work, albeit they also do while awake. There are some internal senses too that function to varying extents while asleep or awake, like the digestive system and others.
It can be theorized that during sleep, since interpretation is mostly closed to external senses, internal senses [in the mind] have a chance to get prioritized, as functions. This means that the sets of chemical signals for internal senses get some of the highest volumes, and their sets of electrical signals have the most intensities, something that is often common for sets of external senses during the day.
Also, since external senses are not getting interpreted, their chemical signals usages are limited. This means they are not depleted or stretched, like during extended use by day. So, after waking up sometimes, there is a refreshing feeling because the chemical signals begin a new use cycle, conceptually.
It is theorized that sleep results, in general, when the sets of signals of external senses fall in volume and intensity. This implies that when the eyes are closed, the temperature is fair, the sounds are low, with no chewing, walking, or other activities, sleep is likelier. So, as the volume [sets of chemical signals] and intensity [sets of electrical signals] fall for interpretation of external senses, those of internal senses rise. It is when they [the sets] array in a certain way that sleep eventually results. Although, certain internal states, like volume or intensity for anxiety, or depression, or worries, could affect falling asleep.
This means that it is possible to present a model for sleep, using sets of electrical and chemical signals. This model can then be provided to an AI chatbot, to feed data as a parallel to what might be going on internally, so as to structure the states before, during and after sleep, including dream and dreamless states.
The purpose will be to ensure that sleep across ages is beneficial to health [physical and mental] rather than becoming a source of risk, since sleep deprivation may result in the lack of internal senses getting their prioritization, in routine that they need for some of their proper functions, conceptually.
Melatonin and adenosine, which are molecules associated with sleep, can be categorized as chemical signals. This concept can be used as sleep structuring information, with AI.
There is a new paper [4 March 2025] in BMJ, Impact of different types of physical exercise on sleep quality in older population with insomnia: a systematic review and network meta-analysis of randomised controlled trials, stating that, “Sleep quality declines with age. Older people have more significant insomnia than younger people. Between 30% and 48% of seniors complain of sleepiness, while 12–20% have insomnia problems. Family doctors see about 5.5 million patients every year for insomnia. Strong evidence links sleeplessness to depression, anxiety and other mental health disorders. Several studies have linked sleeplessness to metabolic syndrome, hypertension and heart disease. Cognitive decline and prostate cancer risk are related to insomnia. Insomnia also increases the likelihood of job impairment, absenteeism and poor performance, which costs the healthcare system and society. Global Pittsburgh Sleep Quality Index (GPSQI) and subdomain score. This review comprised 2170 people from 25 trials. Direct meta-analysis revealed significant improvement in GPSQI with combined exercise (unstandardised mean difference (USMD) −2.35, 95% CI−3.13 to –1.57, p<0.001, I2=69.13%). GPSQI decreased considerably with aerobic activity (USMD −4.36, 95% CI −7.86 to –0.86, p=0.01, I2=97.83%). For the network meta-analysis, strengthening, aerobic and combination exercise significantly lowered GPSQI (USMD−5.75, –3.76 and −2.54, respectively). Strength training improved GPSQI scores most effectively (SUCRA 94.6%). Exercise that strengthens muscles, rather than aerobic or combination exercises, is the most effective way to enhance sleep quality.”
