Around 1 in 2 adults experience insomnia at some point, and 1 in 10 struggle with it regularly. But here’s what most people don’t realise…insomnia isn’t a disease. It’s a signal, often caused not just by poor habits, but by the way we think.
That’s where Rational Emotive Behaviour Therapy (REBT) comes in. If you’ve ever told yourself, “I must sleep tonight, or I won’t cope!” you’re not just losing sleep. You’re adding fuel to the fire.
How much sleep do I actually need?
Most adults need 7-9 hours of sleep a night. As we age, our sleep becomes lighter and more broken.
Women are more prone to insomnia, due to hormonal changes and higher rates of anxiety and depression.
But the key isn’t chasing a magic number. It’s learning to sleep well enough to function, and to let go of the rigid demands we place on ourselves.
Why can’t I sleep?
Sometimes it’s environmental; too much caffeine, a hot room, or noisy neighbours. But more often, it’s psychological. Anxious thinking, stress, or over-identification with sleep problems can keep us stuck.
In REBT, we look at the beliefs and thoughts driving your emotional response. For example:
- “I must sleep perfectly tonight, or I won’t be able to function.”
- “If I keep waking up at 3am, something’s wrong with me.”
These beliefs are demanding, catastrophic, and often false. They cause emotional arousal — exactly what keeps your brain from switching off.
What about those 3 a.m. wakeups?
Waking in the night is normal but overthinking can prolong it. Instead of spiralling, try a mental trick. Imagine placing your worries in a box beside the bed. Tell yourself, “This can wait until morning.”
You’re not ignoring your thoughts, you’re choosing to deal with them at a rational time.
5 habits that help (backed by REBT wisdom)
Good habits support sleep, but your thinking style needs to support it too.
1. Use your bed for sleep (and sex) only
No phones, laptops, or worrying in bed. This trains your brain to associate bed with rest, not activity or stress.
2. Keep a consistent wake time
Get up at the same time every day, even on weekends. This sets your internal clock and builds sleep pressure for the next night.
3. Wind down with purpose
Dim the lights, turn off screens an hour before bed, and do something calming. But here’s the REBT twist: don’t demand relaxation. If you’re lying there thinking, “I should be winding down by now!”, you’re defeating the purpose.
4. If you’re awake, get up
Stuck awake for more than 30 minutes? Leave the bed and do something boring in another room. Return only when sleepy. This breaks the mental link between your bed and anxiety.
5. Watch your thinking
Use REBT to challenge unhelpful beliefs:
- “I can’t function without 8 hours.” → “I’d prefer 8 hours, but I can manage on less.”
- “I must not wake up during the night.” → “It’s normal to wake briefly, I can still feel rested.”
The biggest sleep blocker: Pressure to sleep
Ironically, the more you try to force sleep, the harder it gets. That classic thought, “I must sleep or tomorrow will be ruined!” activates stress, not sleep.
REBT teaches that our distress doesn’t come from lack of sleep alone, but from our beliefs about sleep. When we change our thinking, our emotions (and often, our sleep) follow.
Try this flexible belief:
“I’d really like to sleep tonight, but if I don’t, I’ll cope. It might not be fun, but it won’t be a disaster.”
When to get support
If you’ve been struggling with sleep for more than a few weeks, and nothing’s working, it’s worth talking to a doctor or therapist. Sometimes physical issues like sleep apnea or restless legs syndrome are the cause.
But if you believe your thoughts and stress are the culprits, REBT can make a real difference. By helping you challenge rigid thinking and develop emotional resilience, you reduce the very anxiety that’s keeping you up at night.
The bottom line
Sleep is not something you control, it’s something you allow. The more pressure you put on it, the more it slips away.
REBT helps you soften your demands, let go of perfectionism, and remember this truth:
One bad night isn’t the end of the world. You’ll cope. You always do.
