When you encounter 「失神する」(しっしんする), you're looking at a verb that specifically means 'to faint' or 'to lose consciousness temporarily'. This isn't just about falling asleep; it implies a sudden, usually temporary, loss of awareness and ability to stand. You'll often hear this in contexts where someone has been under a lot of stress, experienced a shock, or has a physical reaction to something. It’s a bit more formal than a casual 'pass out,' and carries the nuance of a medical or physiological event.

Unconscious, unknown consciousness. This implies a more serious and possibly prolonged state of unconsciousness, often used in medical reports after accidents or severe conditions, rather than a temporary faint.
Dizziness upon standing up. This is a feeling of lightheadedness or vertigo, often a precursor to fainting, but not the same as actually losing consciousness (失神する).

Often used interchangeably with 失神する, but there's a subtle difference in nuance. 気絶する generally implies a sudden, often dramatic loss of consciousness due to shock, fear, or a sudden physical impact.
While both mean 'to faint', 気絶する often carries a connotation of a more abrupt and possibly emotionally or physically triggered unconsciousness, whereas 失神する tends to be more medically descriptive of a temporary loss of consciousness due to insufficient blood flow to the brain.
彼はショックで気絶した。 He fainted from shock.
This is a broader term for 'to lose consciousness' and can encompass various reasons for unconsciousness, not just fainting.
失神する specifically refers to fainting. 意識を失う is a more general phrase that could refer to fainting, being knocked out, falling into a coma, etc.
彼女は事故で意識を失いました。 She lost consciousness in the accident.
倒れる means 'to fall down' or 'to collapse'. While fainting often involves falling, 倒れる doesn't always imply loss of consciousness.
You can fall down without fainting (e.g., tripping). 失神する specifically means to faint and lose consciousness. You can use 倒れる to describe the physical act of falling after fainting, but it's not the same as 失神する.
彼は疲れてベッドに倒れた。 He collapsed onto the bed from exhaustion.
This is the opposite of losing consciousness – it means 'to wake up'. It's confusing because the context of fainting often involves waking up afterwards.
失神する is the act of fainting. 目を覚ます is the act of regaining consciousness. They are antonyms.
彼女は数分後に目を覚ました。 She woke up a few minutes later.
Very similar to 意識を失う and 失神する, often used interchangeably, but can sometimes have a slightly more colloquial or less formal feel than 失神する.
While often used synonymously with 失神する, 気を失う can sometimes imply a more general 'losing one's senses' or 'being overwhelmed', though in medical contexts, it's virtually the same as losing consciousness. 失神する is more precise for the physiological act of fainting.
彼は暑さで気を失った。 He lost consciousness from the heat.
