A “sleep divorce” is when a couple chooses to sleep in separate beds or separate rooms to get better-quality sleep — and despite the dramatic name, it has nothing to do with relationship breakdown. It’s a practical sleep strategy that’s become increasingly common and openly discussed. The rationale is sound: a partner’s snoring, movement, different

CBD (cannabidiol) shows promise for sleep, but the evidence is still developing and more mixed than the marketing suggests. The clearest mechanism is indirect: CBD appears to reduce anxiety for many people, and since anxiety is a major driver of poor sleep, easing it can improve sleep. Direct evidence that CBD is a reliable sleep

The “colors” of noise differ in their balance of high and low frequencies, and each suits sleep differently. White noise contains all frequencies at equal intensity (a sharp, staticky hiss) and is best at masking disruptive sounds. Pink noise emphasizes lower frequencies (a softer, more balanced sound like steady rain) and has the most research

Sleep is essential for memory and learning. During sleep, the brain consolidates memories — transferring and stabilizing the day’s experiences into long-term storage, integrating new information with existing knowledge, and strengthening the neural connections that hold memories. Different sleep stages handle different jobs: deep (slow-wave) sleep is especially important for consolidating facts and events (declarative

That groggy, disoriented feeling when you wake is called sleep inertia, and it’s a normal physiological state that can last anywhere from a few minutes to 30 minutes or more — occasionally longer. It’s worst when you’re woken from deep sleep, which is why an alarm catching you mid-cycle feels brutal. To wake up easier:

To find your ideal bedtime, work backward from when you need to wake up, allowing for the hours of sleep your age requires (7–9 hours for most adults) plus about 15 minutes to fall asleep. For example, to wake at 6:30 a.m. with 8 hours of sleep, you’d aim to be asleep by 10:30 p.m.,

Weighted blankets — heavy blankets (typically 5–30 lbs) filled with materials like glass beads — may genuinely help some people sleep better, primarily by reducing anxiety and promoting calm through a mechanism called deep pressure stimulation. The evidence is most supportive for people with anxiety, and there’s reasonable support for benefits in conditions like insomnia

We dream primarily during REM (rapid eye movement) sleep, when the brain becomes highly active while the body is temporarily paralyzed. Science doesn’t have one definitive answer for why we dream, but the leading evidence-based theories suggest dreams serve several overlapping functions: processing and regulating emotions, consolidating memories and integrating new information, simulating threats and

Sleep medications range from over-the-counter options (melatonin, antihistamines) to prescription hypnotics (such as “z-drugs” and benzodiazepines) and other prescription medications used for sleep. They can be genuinely useful for short-term or situational insomnia, but they share important limitations: most treat the symptom (being unable to sleep) rather than the underlying cause, many carry risks of

For most people, side sleeping is the best overall position — it keeps the airway open (reducing snoring and sleep apnea), supports the spine when done with proper pillow support, may aid the brain’s glymphatic waste clearance, and is recommended in pregnancy. Back sleeping is good for spinal alignment and pressure distribution but worsens snoring
