Abstract: A safe; effective squatting toilet seat has multiple embodiments to simulate the natural mode of bowel and urine evacuation in the squatting position practiced for centuries before modern sitting toilet was introduced. This inventive design bends the thigh at hip, which pushes back the pubic bone and tilts the pelvis forwards that bends the torso resulting in relaxation of the puborectalis and pubourethralis muscle noose at anorectal junction while straightening the rectum to come in alignment with the anus for fast easy and fast bowl evacuation. This invention also provides a separate insertable squatting toilet seat placed on the top of the existing toilet seat on the toilet bowl. It is provided with urinal embodiment to prevent urine spilling and to induce easy flow of urine in females due to relaxation of pubo-rectalis-urethralis muscle. Embodiments include toilet bowl sterilization by germicidal visible violet-blue spectrum light, toilet deodorizer, and seat warmer.
