Dr. Shereene Idriss's Must Haves: From Silk Pajamas to a Diaper Rash Cream

Dr. Idriss deems the Eight Sleep Pod Cover ($2,245, originally $2,295) a "marriage savior" because it allows her and her husband to control the temperatures of their respective sides of the bed. It works by heating or cooling a water pipe that runs through the mattress, subsequently adjusting the temperature of the bed. "You don't even hear it happening," she says. It can cool to 55 degrees Fahrenheit or warm to as high as 110 degrees Fahrenheit, and throughout the night, it will adjust the temperature to your ideal setting.

Pro Tip: This also comes with an app that can track your sleep stages, heart rate, respiratory rate, and more, so it's great for those who are looking for insight into their health.
