Many people assume they have a “sleep problem,” when in reality they have a stress problem. To understand how stress affects sleep, it helps to look at what happens in the brain and body at night. If you struggle with a racing mind, restlessness, or a body that won’t fully relax when you lie down, stress may be the real issue—not your sleep system.
