Explainers on the sleep problems that don’t have one obvious cause: waking up tired, shallow or light sleep, frequent waking, and the environmental and habit-based fixes that can help you get deeper, more consistent sleep.
Seasonal affective disorder (SAD) is a form of depression tied to the time of year, most often starting in fall and easing in spring. Unlike some other forms of depression, the winter-pattern version usually comes with hypersomnia — sleeping more than usual and still feeling drowsy during the day — rather than insomnia, and it’s […]
Exercise timing matters for sleep, but not in the simple “never work out at night” way it’s often presented. Research shows both morning and evening exercise can improve sleep quality — what actually matters most is intensity and how close to bedtime a hard workout happens, not the time of day itself. Who This Is
Sleep inertia is the groggy, foggy feeling right after waking — even after a full night’s sleep. It usually peaks within the first 15 to 30 minutes and fades within an hour, but it can last longer depending on what stage of sleep you were in when you woke up and how much sleep debt
Antidepressants can help or hurt sleep depending on which one you’re taking — some are activating and tend to cause insomnia, while others are sedating and are sometimes prescribed specifically to help with sleep. Most sleep-related side effects ease within a few weeks, and timing when you take the medication often matters as much as
Depression and sleep problems go hand in hand more often than not. Most people with depression struggle with insomnia, and a smaller number sleep far more than usual — both patterns can make depression harder to manage, and both tend to improve when sleep is treated directly alongside the depression itself, not just left to
Pulling an all-nighter feels like it buys extra time, but the research is fairly blunt: it usually costs more than it gives back. Sleep deprivation at that level impairs attention, memory, and mood to a degree comparable to legal alcohol intoxication, and the studying or work done during the all-nighter is much less likely to
Sleep and weight gain are more closely linked than most people realize. Poor or short sleep changes the hormones that control hunger and fullness, raises stress hormones that promote fat storage, and makes it harder to resist high-calorie food the next day. None of this is about willpower — it’s a predictable biological response to
Postpartum sleep deprivation is one of the most universal, least talked-about parts of new parenthood. Studies show new parents often get just 5–6 hours of fragmented sleep a night in the first few months — and fragmented is the key word, since broken sleep takes a real toll even when the total hours look okay
Ozempic and sleep can have a complicated relationship. If you started a GLP-1 medication like Ozempic, Wegovy, Zepbound, or Mounjaro and your sleep has changed since — better in some ways, worse in others — you’re not imagining it. These drugs can genuinely affect sleep in both directions, and the reasons are different depending on
If your sleep seems to shift throughout the month — harder to fall asleep some weeks, waking up more in others — that’s not a coincidence. Hormonal changes across the menstrual cycle have a real, measurable effect on sleep quality, and understanding the pattern can make it easier to plan around it rather than be
