A few things you
might still be wondering.
Open a question for a short explanation. Return here whenever you need a reminder.
Your questions, one at a time.
Does snoring always mean sleep apnoea?
No. Snoring alone does not establish it. Observed breathing pauses, gasping or persistent daytime sleepiness are important reasons to seek assessment.
Do I have to wait three months to discuss insomnia?
No. Three months describes the long-term category. Problems that affect daily life can be discussed earlier.
Can healthy sleep habits cure every problem?
No. They can support sleep, but insomnia, breathing problems and other conditions may need targeted treatment.
Is restless legs the same as leg cramps?
No. Different conditions can cause discomfort. The urge to move, timing and relief with movement are useful details for an assessment.
Should I take iron for restless legs?
Ask a clinician. Iron deficiency can be relevant, but symptoms alone cannot tell you whether you need supplements or what treatment is appropriate.
Are nightmares and night terrors identical?
No. A nightmare is a bad dream someone may remember after waking. A night terror involves an event while still asleep and is often not remembered.
Is acting out a dream harmless?
Not always. Repeated kicking, punching or injury risk needs assessment. Different conditions can resemble dream enactment.
Why do I feel sleepy after a full night in bed?
There are several possibilities, including sleep disruption, inadequate sleep or medicines and medical conditions. Spending time in bed does not rule them out.
Will everyone need an overnight sleep test?
No. Assessment guides which tests, if any, are useful. Testing for suspected sleep apnoea can often happen at home.
Are sleeping tablets the long-term answer?
Not usually on their own. CBT-I is commonly recommended first for long-term insomnia. Discuss any medicines with your clinician; do not change or start treatment based only on this module.
