Hi! Health reporter Olivia Willis here with your weekly health digest.
 

This week, it was revealed that one in three Australian women live with migraine and have experienced one in the past three months.
 

Their symptoms include throbbing, pulsating pain, light and sound sensitivity, nausea, vomiting, dizziness and brain fog.
 

The data suggests the prevalence of migraine is much worse in Australian women than experts previously estimated.
 

"Migraine is far more than a bad headache, it's a neurological disease," Alfred Hospital neurologist Emma Foster said.
 

"The attacks last between four to 72 hours. It's a very distinct type of headache that's accompanied by additional symptoms that can be … even more debilitating than the severe pain."
 

So why is migraine more common in women?
 

It's largely thought to be related to sex hormones, as well as genetic, environmental and social factors.
 

Women's health advocates want to see more migraine research and workplace consideration.
 

Also this week, confusion over Australia's free childhood dental scheme is putting children's oral health at risk.
 

And in case you missed it: a baby was born in the US from an embryo frozen more than 30 years ago, breaking the record for the world's "oldest" baby.
 

Finally, this week: it's impossible to escape microplastics — they're in our food and water, and the air we breathe is teeming with them. So how can we minimise our exposure without resorting to living in a cave? Check out the latest episode of Lab Notes to find out.
 

I'll catch you next week.
