History of National Sleepover Day

National Sleepover Day was established in 2017 through a creative partnership between Cosmopolitan magazine and the beauty brand bareMinerals. To launch the inaugural celebration, the founders organized a massive, public slumber party in the middle of New York’s Times Square. This event featured a giant bedroom set on Broadway where participants could enjoy makeovers and participate in group discussions. The holiday was specifically designed to promote a new line of mineral makeup that was marketed as being pure enough to sleep in without damaging the skin.

While the formal holiday is relatively new, the concept of the sleepover became a staple of American youth culture in the mid-20th century. During the 1950s and 1960s, these gatherings transitioned from simple overnight stays into complex social events characterized by specific rituals like pillow fights and shared secrets. The term “sleepover” first gained significant media attention in the late 1950s, and by the 1970s, it had become a quintessential rite of passage portrayed in popular books and films.

Why is National Sleepover Day important?

This day highlights the psychological and social benefits of spending extended time with peers in a relaxed, informal setting. Sleepovers provide a unique environment where the typical barriers of school or professional life are removed, allowing for more honest and vulnerable communication. For younger participants, these events foster independence by giving them the experience of staying away from home in a safe, supervised environment. For adults, the holiday offers a rare chance to reconnect with friends and relieve the stresses of adult responsibilities through nostalgia and play.

The holiday also recognizes the role of shared experiences in forming strong communal bonds. Activities like watching a series of movies, playing games, or preparing a meal together create a shared history that can sustain friendships for decades. By designating a specific day for these gatherings, the holiday validates the importance of leisure and friendship as essential components of a healthy life. It serves as a reminder that taking time for “unproductive” social fun is necessary for mental well-being and social cohesion.

• It encourages the development of strong social bonds through shared late-night activities.

How to Celebrate National Sleepover Day

The most classic way to celebrate is by inviting a group of friends over for a traditional slumber party. You can transform a living room or basement into a cozy lounge using plenty of pillows, blankets, and string lights to set the mood. Planning a specific theme, such as a retro 1990s night or a movie marathon featuring a favorite film franchise, can help organize the evening’s entertainment. The focus should be on creating a comfortable space where everyone feels welcome to relax and stay up late.

Food is a central element of any successful sleepover, and interactive meal stations are a popular choice. Setting up a DIY taco bar, a pizza-making station, or a colorful candy buffet allows guests to customize their snacks throughout the night. For a more modern twist, some participants use the night for collective self-care, such as trying out new skincare routines or doing manicures while listening to music. Regardless of the specific activities, the goal is to enjoy the rare luxury of having no morning alarms and plenty of time for conversation.

• Invite your closest friends over for a night of movies and classic board games.
• Set up a comfortable sleeping area with sleeping bags and extra cushions.
• Prepare a variety of easy-to-share snacks like popcorn, sliders, and nachos.
• Create a playlist of your favorite songs to act as a background for the night.
• Take a break from mobile devices to focus entirely on in-person interactions.
