Hormonal sleep disruption guidance, mechanism to safety — why estrogen and progesterone shifts disrupt sleep, and what's safe to try or discuss with a clinician.
Sugar-free candy can cause gas, bloating, and diarrhea that interfere with falling asleep and staying asleep. This article explains how sugar alcohols trigger these digestive problems and why timing and dose matter for your sleep.
Most teen athletes average only about 6.3 hours of sleep per night despite needing 8 to 10. This gap measurably hurts reaction time, accuracy, endurance, and increases injury risk — here is the evidence behind the recommendation and what the deficit actually costs.
Learn how to interpret your local Air Quality Index (AQI) to understand its real impact on your sleep quality tonight, and when to take protective action before bed.
Learn evidence-based techniques to calm your nervous system during a tornado watch so you can rest without compromising safety. This article explains grounding exercises, controlled breathing, and smart information boundaries that reduce storm anxiety while keeping you alert enough to respond to warnings.
Sleep problems affect up to 75% of cancer patients and survivors, driven by a cycle of treatment side effects and maladaptive sleep behaviors. This article explains the mechanisms and evaluates the most effective treatments — from CBT-I to melatonin — ranked by strength of evidence.
Learn why car accidents often cause insomnia and nightmares through both psychological trauma and physical injury, and discover clinical red flags that signal when it's time to seek help.

This article examines the evidence and provides practical guidance for using rain sounds as a timed sleep-onset tool.
Grief and sleep share a bidirectional relationship that can create a difficult cycle. This article explains the neurobiology behind sleep disruption after loss and offers evidence-based strategies for breaking the cycle, with sleep identified as the most actionable entry point.
Mental health screenings like the PHQ-9 and GAD-7 can identify sleep problems and guide treatment that measurably improves sleep quality. Learn how the screening-to-treatment pathway works and what the research shows.
