A 23-year-old woman with a rare sleep condition has "lost so many years" because of her "insatiable appetite for sleep".

Helena Smythe says she feels tired all day – no matter how well she sleeps at night – and has to take daily naps of at least two hours.

She has a little-known condition called Idiopathic hypersomnia, also known as excessive daytime sleepiness.

Smythe has even fallen asleep in an A-Level exam and passed up invitations with friends as she needs to nap.

"I have an insatiable appetite for sleep and while some people can just perk themselves up with a coffee or some caffeine, that doesn’t work for me," she says.

"I have to nap every day, and 20 minutes or half an hour is not enough. It needs to be two or three hours at a time.

"The main symptom is that I feel excessively sleepy in the day, no matter how much sleep I get at night or how long I sleep for."

Doctors do not know the underlying cause of hypersomnia so there is no cure and the condition can only be managed through medication.

Smythe, who has lived with hypersomnia since the age of 12, says it has made her "miss out" as a teenager.

"I would miss school, have to cancel social events and even fell asleep during an A-Level exam," she says.

"I had to plan my whole life around sleep and pick between academia and friends.

"I can’t tell you how much I missed out on as a teenager; I have lost so many years to sleep."

Smythe is due to start a full-time job soon and said she is nervous that her need for sleep may disrupt her work.

She is taking part in sleep studies at Royal Papworth Hospital in Cambridge and said that medication is partially helping her.

"I am given medication which helps to alleviate my symptoms and although it has not entirely removed the problem, my quality of life is much better and I am able to get on with life having had a much more ‘normal’ level of sleep.

"My advice to people is that sleep health needs to be taken seriously. It should be just as important as eating the right food, not drinking too much alcohol, not smoking and getting physical exercise.

"Some of the advice that has worked for me has been about improving sleep hygiene, and in particular getting into a proper routine by going to bed and waking up at the same times each day."
