Building a company will mess with your sleep. This is not a personal failing or a character flaw or a sign that you’re doing it wrong.

Most jet lag advice is garbage. “Drink lots of water.” “Get on local time as soon as possible.” “Try not to nap.” None of it is wrong, exactly. It’s just imprecise enough to be useless. The traveler executing this advice still loses 4–7 days of function on a major time zone change, accepts it as

If you’ve started taking magnesium for sleep, you’ve probably noticed something strange: not every form works the same. The pills from the grocery store didn’t do much.

Most people who experience night sweats can blame the environment. The room was too warm. The blankets were too heavy. The window was closed. It was a hot summer night. These are real causes of nocturnal sweating, and they’re easy to fix. But there’s a different pattern that’s much more diagnostic: sweating heavily at night

It usually starts when you get into bed. Within minutes, your feet feel hot. Not just warm — hot, sometimes burning, sometimes prickly, sometimes deep aching warmth that seems to come from the bones themselves. You kick off the covers. You stick your feet outside the sheets. You press them against the cool side of

You’re in bed. The room is at a reasonable temperature. The blankets are pulled up. And yet your feet feel like ice blocks. They’re so cold that warming them under the covers takes 30 minutes — or doesn’t happen at all. You consider socks, then reject them as too restrictive, then reconsider. You contemplate a
