Sleep in a pitch-black room

Even if you choose to sleep with an eye mask, nothing can create a dark, sleep-inducing environment better than blackout curtains. Most luxury hotels, like the JW Marriott Cancun Resort & Spa, know the importance of pitch-black sleeping conditions and ensure not even a crack of light makes it into your hotel room once shades are pulled. If you want to do the same in your home without spending a fortune, the NICETOWN Thermal Insulated Grommet Blackout Curtains for Bedrooms ($35.95, amazon.com) are the way to go.
