There are a few different elements that comprise the overarching idea of "sleep hygiene." The first is called sleep restriction. "Sleep restriction means having a set bedtime and set wake time, even on weekends, even on holidays, even when people visit you," Dr. Dasgupta explained.
The second element is stimulus control. "That means the bed is only meant for sleeping," he said — not answering emails, scrolling through social media, or conducting any kind of work. You should only be in bed when you're ready to sleep.
The third element of good sleep hygiene is focusing on when and what you eat before bed. Dr. Dasgupta recommends avoiding eating too close to bedtime, as well as avoiding caffeine, high levels of sugar, and the overconsumption of alcohol, as all of these things can affect the quality and quantity of your sleep.
