Why I write about this
“Growing cannabis since the early 2010s and writing about cannabinoids taught me that good CBD content starts with how the plant is actually grown and processed, not just what the label claims.”

How to read a certificate of analysis COA
Cibdol batch 260084, read field by field, covering what the batch header fixes, why most result cells say Conform, what the purity limits are measured against, and what the signature at the end does not tell you.
Pink noise and the evidence behind coloured sound
A review of acoustic colour definitions, evidence ratings for continuous sound, and laboratory findings on pink noise and sleep structure.
What core sleep means on a wearable device
Core sleep on modern smartwatches corresponds to laboratory light sleep, stages N1 and N2. Earlier research used the term differently, while consumer devices show measurable differences from clinical polysomnography.
Why do we sleep and what the research measures
Researchers have proposed several explanations for sleep, from energy conservation to neural maintenance. This review examines what empirical studies have measured in humans and animals.
Biphasic sleep across history and modern science
This article outlines historical and modern research on biphasic sleep, contrasting preindustrial accounts with field studies and controlled polyphasic trials.
The military sleep method, origins and evidence
The military sleep method traces back to a 1981 book by track coach Bud Winter. Popular retellings claim fast results, but the method itself has not been tested.
Understanding sleep debt and how recovery sleep works
Sleep debt reflects the cumulative difference between required and obtained rest. Laboratory trials reveal how performance deficits accumulate over time and examine the dynamics of subsequent recovery.
How accurate is a sleep tracker at scoring rest stages
Validation studies compare consumer sleep technology with laboratory recordings. Trackers detect sleep reliably but misclassify wakefulness and show inconsistent agreement on stages.
Yoga nidra session steps and scientific evidence
Yoga nidra is a structured guided relaxation practice. Research has evaluated its physiological patterns and measured overnight sleep changes with mixed results.
What objective studies reveal about sleeping positions
Sensor data show adults spend over half the night on their side, with shifts decreasing as age increases. Evidence linking spinal symptoms to specific positions remains thin.
How long can you go without sleep
Documented records describe individuals staying awake for days, but laboratory evaluations show that cognitive lapses and sensory changes begin within the first 24 hours.
What scientific research records about sleep sounds
Controlled research distinguishes between broadband noise, nature recordings and environmental sounds, showing mixed outcomes on sleep architecture and awakenings.
