Left eye twitching is often caused by lack of sleep or too much caffeine, both of which can lead to fatigue and involuntary muscle spasms. Reducing caffeine intake, getting adequate rest, and managing stress typically resolve the twitching within a few days.

Explanation

Eye twitching, also known as myokymia, can be bothersome. It may be related to fatigue or caffeine consumption.

Fatigue: According to research, fatigue can impact how our body performs and may lead to muscle twitches, including in the eye. Not getting enough sleep might make these twitches more likely.

Caffeine: Another study mentions how caffeine, commonly found in energy drinks, can influence our bodies. Consuming too much caffeine might make muscles, like those around the eye, twitch more.

For those experiencing eye twitching, it might help to get more rest and reduce caffeine intake. If the twitching continues or is bothersome, you can check your symptoms to better understand what might be causing it and whether you should talk to a healthcare provider.
