There’s a new fad that “wellness influencers” are pushing and it involves taking in some sun in an unusual place:

She didn’t start it, but Metaphysical Meagan, who has 24,000 followers on Instagram, has claimed that “30 seconds of sunlight on your butthole is the equivalent of a full day of sunlight with your clothes on!” She’s also found it gives her surges of energy almost immediately and better sleep.

The New York Post reports:

The hottest trend gripping wellness die-hards is tanning their cans, or “perineum sunning,” as influencers are calling it.

“In a mere 30 seconds of sunlight on your butthole, you will receive more energy from this electric node than you would in an entire day being outside with your clothes on,” says an influencer, who goes by Ra of Earth. In a viral video that has racked up more than 35,000 views, he gestures toward the sun as three naked men lie down, point their backsides to the sky and make sounds of pleasure.
