As you hit adulthood, it’s likely you’ve noticed one or two annoying symptoms.

Not urgent stuff that has you rushing to the doctor, but weird quirks of having a body not entirely act how you might want it to.

Kind of like an unexpected computer glitch that disrupts your flow for a moment or two before getting back to normal again.

So to the pinnacle of strange and (usually) meaningless bodily malfunctions: the eyelid twitch.

It’s annoying and seems to come out of nowhere: the eyelid twitch, in which your eyelid starts randomly twitching out of nowhere, it not uncommon. It can happen to anyone, but is common in middle aged and older women.

According to UCLA Health, f it’s only happening occasionally, the eyelid twitch is usually nothing to worry about. If it’s one eyelid twitching it could be something known as ocular myokymia. If it’s more frequent and both eyes are twitching at the same time, it could be benign essential blepharospasm.

But if your finding that your eye twitch is common or problematic and accompanied by other symptoms, it’s always worth getting checked by a doctor, since in rare cases it could have a more serious cause.

If it’s just occasional? You’re probably just tired, or maybe you’ve had too much caffeine.

But it’s not just tiredness and caffeine that could be causing your twitchy eyelid. Other common causes include stress, bright lights and driving.

The good news is that unless your twitching is severe or caused by an underlying condition, you won’t need treatment – if you want rid of the twitch, there are some lifestyle adjustments you can make, many of which will benefit your wellbeing in other ways too.

Reducing your caffeine intake – or cutting it out completely – is likely to be a big help, as is getting enough sleep.

It can also be very beneficial to reduce any stress that is affecting your life, and to wear sunglasses if it’s bright too.

While it’s usually not serious, the eyelid twitch can be a sign that your body is stressed or tired – it pays to listen to it.
