Learn to dismount step by step: out of the saddle, a safe landing and a calm horse, with your helmet still on until the horse is safely put away.
Is dismounting really a skill of its own? The honest answer: yes. You learn it deliberately, because a calm dismount ends the lesson safely and does not startle your horse. It is one of the skills you can get right in one or two supervised sessions.
One point is often underestimated: the danger does not end when you get off. A prospective study from Hamburg recorded 24 patients with hoof-kick injuries, and every accident happened while the horse was being led or groomed. Only 2 of 24 patients (8.3 %) wore a helmet, and two thirds broke the eye socket, midface or lower jaw [1]. So your skill does not stop on the ground, it carries over into leading and caring for the horse.
On the physics: I found no studies on dismounting itself. What was measured is mounting. From the ground the saddle presses harder on the horse's back than from a 35-centimetre mounting platform, most of all when the right leg swings up [2]. Dismounting is that movement in reverse. The transfer is plausible but not measured, so the rule is: soft and controlled instead of swinging.
Ride a calm halt on level ground. Wait until the horse really stands, not at the very first slowing down. Milestone: You consciously count three breaths before you move. This is riding-school practice, not a study value.
Take both reins in your left hand, rest them just in front of the withers and do not lean on the horse. Then take both feet out of the stirrups. If you free only one foot you can get caught while dismounting. That is the reason for this step.
Support yourself with both hands at the front of the saddle or on the withers. Swing the right leg high and straight over the croup without touching the horse. You do not slide down the side of the saddle, you lift yourself slightly for a moment.
Land with slightly bent knees on the left of the horse. Do not drop, and keep the reins loose so the horse is not pulled. Milestone: The horse is still standing on the same spot when you land.
Run the stirrups up the leathers so they do not swing against the horse. Loosen the girth in two calm steps. Take the reins over the horse's head and lead the horse on your left, with the helmet still on your head.
Dismounting does not replace supervised training. As a beginner you never dismount unsupervised, and you have girth and stirrups checked by the instructor. If the horse dances or steps away while you dismount, that is not a case for sticking it out but a signal for your instructor.
A safety vest mainly protects the chest; against spinal injuries it was not shown to work in the review [3]. And remember: in a US database of around 54,830 estimated riding spinal injuries, a simple fall was the cause in 53.6 % of cases, and in 39.7 % the rider was bucked, thrown or kicked off [4]. Progression and supervision are the answer, not courage. An emergency bail-out is not a beginner topic and you only practise it with a trainer.
Turn dismounting into a routine you run even in the rush after a long hack: halt, reins in hand, feet out, leg up, soft landing, stirrups up. Horses learn patterns. A routine that never changes makes standing still a matter of course and takes tension out of the moment.
Usually on the left, because horses are led from that side. A biological reason is not proven, it is riding tradition. Swap sides only with your instructor so that saddle and horse stay symmetrical.
Yes, that is the safe way: you cannot get caught if the horse moves. It is riding-school standard and not a research question.
With slightly bent knees on the left of the horse, eyes forward, reins loose. Landing means cushioning, not jumping down. Practise at the mounting block with your instructor until it works calmly without hopping.
No, not right away. All 24 hoof-kick injuries in the Hamburg study happened while leading or grooming, and only 2 patients had a helmet on [1]. The helmet stays on until the horse is cared for.
Stay calm, keep hold of the reins, bring the horse back to a stand with your supervisor and start again. If it keeps stepping away, you and your instructor look into possible causes such as restlessness or pain.
