Horses can rest to a significant extent while standing up, but to achieve REM sleep – a deep sleep also called paradoxical sleep or desynchronized sleep – they must lie down. They can only doze in the standing position, as we humans may do on the sofa, but to achieve proper sleep, they must lie down, like these horses photographed by Ron Callari on Cherokee Farm Road in Beaufort. To submit a Lowcountry Life photo, you must be the photographer or have permission to submit the photo to be published in The Island News. Please submit high-resolution photos and include a description and/or names of the people in the picture and the name of the photographer. Email your photos to firstname.lastname@example.org.
