Sleep Tracker Accuracy: What Your Device Can (and Can't) Tell You About Deep Sleep

Where they struggle is sleep stages, since wearables don't measure brain waves the way an in-lab sleep study does.

The Sleep Setup That Actually Works: Positions, Masks, and What Your Body Needs at Night

The Sleep Setup That Actually Works: Positions, Masks, and What Your Body Needs at Night

If you wake up tired, restless, or unrested even after a full night's sleep, position might be part of the problem, and it's one of the quieter pieces most people overlook. Side sleeping supports breathing and digestion, back sleeping works against you if you snore, and stomach sleeping offers the fewest benefits of the three.

The wrong form of magnesium can act as an osmotic laxative. Artificial sweeteners disrupt gut flora. Carrageenan promotes intestinal inflammation. Titanium dioxide has been banned as a food additive in Europe for genotoxicity concerns. For migraineurs, whose gut health directly affects nutrient absorption and neurological stability, supplement quality is not a marketing consideration.

Summer and Migraines: Why Heat Is Harder on the Migraine Brain and How to Stay Ahead of Symptoms

Summer stacks several physiological challenges on top of each other in ways the migraine brain handles poorly. Heat causes vasodilation that activates migraine pain pathways. Sweating depletes the sodium the nervous system depends on. Thunderstorms bring barometric pressure drops that destabilize an already reactive brain. Sleep gets shorter and less consistent. And bright summer light adds sensory load to a nervous system that is already running close to its limit. This blog breaks down what is actually happening at the physiological level and what consistent preparation looks like so summer does not have to mean more attacks.
