How did Jesus bleed through his sweat?


And being in anguish, he prayed more earnestly, and his sweat was like drops of blood falling to the ground. Luke 22:44
            The website WEBMD describes the condition as Hematidrosis.  It’s very rare.  The sweat from someone mixes with blood, usually around the face (skin, nose and mouth). It causes dehydration which partly explains Jesus’ dehydration on the cross (“I am thirsty”).
            The cause of hematidrosis is unknown but appears to be related to stress as the blood vessels in the skin break open and bleed.  Jesus felt the stress of the coming crucifixion, an unimaginable pain he willingly suffered.  Despite all the emotional stress, Jesus followed through to save us from our sins.
NOTE: There’s also a condition called hemolacria, where one cries tears of blood and otorrhea when someone bleeds from their ears.  It's unimaginable how much someone needs to hurt to experience this condition.
