Researchers at the University of Michigan recently made headlines with a striking discovery: families who consistently practice Friday night rituals together see a 40 percent reduction in anxiety disorders among their teenagers. The study, which tracked hundreds of families over several years, found that this single weekly practice created a protective psychological barrier against the crushing pressure of modern adolescent life. Parents across America are now scrambling to understand what makes Friday night so special.
But here’s what those scientists don’t know: Moses already knew 3,338 years ago.
The verse that changed everything appears in Exodus:
This isn’t a suggestion. It’s the fourth of the Ten Commandments, sandwiched between honoring God’s name and honoring our parents. That placement isn’t accidental. Shabbat sits at the intersection of our relationship with God and our relationships with each other—which is exactly where family anxiety gets healed.
The Hebrew word zakhor doesn’t mean passive memory, like remembering where you left your keys. It means active, intentional commemoration. The rabbis teach that zakhor requires concrete action—lighting candles, blessing wine, breaking bread together. We don’t just think about Shabbat. We build it with our hands and our presence.
And here’s where it connects to that Michigan study: those Friday night family rituals weren’t about the specific activities. The researchers found that whether families played board games, ate dinner together, or watched movies didn’t matter nearly as much as the consistency and the phone-free presence. The protection against anxiety came from knowing, with absolute certainty, that Friday night belonged to family and to God. No negotiations. No exceptions. No phones buzzing with notifications about what everyone else is doing.
This is Shabbat in its purest form—a palace in time, as Rabbi Abraham Joshua Heschel called it. You can’t build a palace without walls. The “walls” of Shabbat are its boundaries: no phones, no shopping, no productivity obsession. Inside those walls, something miraculous happens. Teenagers who spend six days a week performing for college applications and Instagram followers get to simply be. Parents who spend every waking moment managing logistics get to look their children in the eyes and see them.
The Torah understood what modern psychology is only now proving: human beings need guaranteed, protected time for connection. We need it written in stone, literally—Shabbat appears on the tablets at Mount Sinai because God knew we’d never prioritize it otherwise. We’re too busy. Too important. Too needed elsewhere.
Rabbi Eliezer teaches in the Talmud that when we observe Shabbat, we become partners with God in creation. Here’s what he means: God didn’t rest on the seventh day because He was tired. He rested to demonstrate that rest itself is creative. Menuha—the Hebrew word for rest that appears in Genesis 2:2—isn’t the absence of work. It’s a positive creation, as real as light or water or human beings. When we rest on Shabbat, we’re not being lazy. We’re creating menuha in our homes and in our families.
That Michigan study found that teenagers with Friday night family rituals showed significantly lower levels of cortisol—the stress hormone—throughout the entire week. The researchers were baffled. How could three hours on Friday night affect Monday afternoon biology class? But anyone who keeps Shabbat knows exactly how. The peace you build on Friday night radiates outward. It reminds you, every single week, that you’re more than your productivity. Your children are more than their grades. Your family is more than the sum of your accomplishments.
The Ten Commandments did not waste words. Every commandment addresses something essential to human flourishing. “Remember the Sabbath day to keep it holy” sits right there next to “You shall not murder” because both protect life. One protects physical life. The other protects the life of the soul—the part of us that withers when we never stop, never rest, never disconnect from the machine of modern achievement.
Friday night rituals buffer against anxiety because they create predictability in an unpredictable world. But Shabbat offers something even deeper: it creates holiness in a profane world. It transforms your dining room table into an altar. It turns your family dinner into a sacred gathering. It takes the most ordinary activities—eating, talking, being together—and elevates them into something transcendent.
The Israelites wandered in the desert for 40 years, and every Friday a double portion of manna fell from heaven. Why? Because even when God is feeding you miraculously, you still need to prepare for Shabbat. You still need to gather twice as much on Friday because rest matters that much. Holiness matters that much. Your family matters that much.
America’s teenagers are drowning in anxiety because they’re living in a world without Shabbat—without guaranteed rest, without protected family time, without walls around the sacred. What those University of Michigan scientists proved is that even secular families, even families who’ve never heard of Shabbat, benefit when they stumble into its wisdom.
Moses didn’t need a research grant to figure out that families need Friday nights. He had something better: a direct line to the God who created human beings and knows exactly what we need. The question for us isn’t whether science can prove Shabbat works. The question is whether we’ll finally listen.
