A woman claims that sunbathing helps give her punani energy and makes her sleep better.

However, doctors have warned others not to copy it.

Social media users were left lost for words after the woman's post about the little-known practice of 'perineum sunning' went viral.

The woman called Meagan took to Instagram to share a very X-rated photo of herself laying flat on her back in the great outdoors, holding her legs in the air with her arms to get some rays on her punani.

According to The Mirror, the woman explained that she begins every day with five minutes of exposing her punani to the sun, and claims it leaves her so energised she's been able to ditch the coffee.

She also said it has drastically improved her sleep but told others it should not be done to 'tan your b***hole' as that is not the intention of the practice.

Meagan, who describes herself as a 'healer', also claimed that 30 seconds of the ritual is 'the equivalent of a full day of sunlight with your clothes on' and should be done between the hours of 7-9am for best results.

Doctors say there is no evidence that sunbathing in this way has any effect on physical wellbeing.
