Sleep better in 7 evidence-based steps: what CBT-I teaches us

Insomnia affects roughly one in three Mauritian adults. CBT-I is the gold-standard non-drug treatment. Here are the seven steps that work — and why sleeping pills usually make things worse over time.

Why sleep is the foundation of mental health

Sleep is not a luxury that competes with productivity — it is the biological process that makes productivity, mood, memory and immunity possible. The brain uses deep sleep to consolidate learning, REM sleep to process emotion, and the whole night to clear metabolic waste through the glymphatic system. Lose two hours a night for a week and the deficit shows up as anxiety, irritability, brain fog and a short fuse with the people you love.

Insomnia is one of the most common complaints we hear at Felicity. The good news is that chronic insomnia has a remarkably effective non-drug treatment: Cognitive Behavioural Therapy for Insomnia, or CBT-I. Studies consistently show CBT-I outperforms sleeping pills in the long run, with no rebound, no dependence and lasting effects.

Why sleeping pills are not the answer

Benzodiazepines and Z-drugs (zolpidem, zopiclone) are widely prescribed for insomnia in Mauritius, often for far longer than the two-to-four-week limit international guidelines recommend. They work in the short term, but the body adapts within weeks, doses creep up, and stopping the medication frequently triggers worse insomnia than the original problem. They also reduce deep sleep — the most restorative stage — meaning a 'medicated' eight hours often leaves you less rested than a natural six.

CBT-I targets the underlying patterns that keep insomnia going: irregular schedules, time spent awake in bed, the anxiety of trying to sleep, and the unhelpful beliefs that build up around it. Most people see meaningful improvement within four to six weeks.

The seven CBT-I steps you can start tonight

  1. Fix your wake-up time, not your bedtime. Get out of bed at the same time every day — including weekends — for at least three weeks. A consistent wake-up is the single most powerful sleep intervention.
  2. Use the bed only for sleep and intimacy. No working, scrolling, or watching shows in bed. The brain needs to re-learn that bed equals sleep.
  3. If you are awake for more than 20 minutes, get up. Go to another room, read something boring under dim light, return only when sleepy. Lying in bed frustrated trains your brain to associate bed with wakefulness.
  4. Cut the nap. If you must nap, keep it under 20 minutes and before 3pm.
  5. Set a wind-down hour. Lights down, screens off, no work, no doom-scrolling. Reading, stretching, slow conversation — anything that lets cortisol fall.
  6. Mind your inputs. No caffeine after midday. No alcohol within three hours of bed (it knocks you out but destroys REM). A heavy meal late will fragment sleep.
  7. Restrict your time in bed temporarily. If you sleep six hours, only allow yourself six and a half hours in bed. This builds 'sleep pressure' and consolidates fragmented sleep into one solid block. A therapist can guide this safely.

What about screen-time and the Mauritian climate?

Two local factors deserve mention. First, evening heat. In Mauritian summers, bedrooms can stay above 28°C, well outside the 18–22°C range that promotes deep sleep. A fan, lighter bedding, and a cool shower an hour before bed make a measurable difference.

Second, screens. The blue-light story is overhyped — the bigger problem is what is on the screen. WhatsApp arguments, work emails and TikTok rabbit holes activate the threat and reward systems exactly when you need them quiet. The fix is not blue-light glasses; it is putting the phone in another room.

When to seek professional help

If you have struggled with sleep for more than three months, if you are using medication nightly, if you wake up panicking, or if daytime fatigue is affecting your work or driving safety, it is time to bring in a professional. CBT-I is delivered in 6–8 structured sessions and works for the vast majority of people who complete it. Felicity offers CBT-I with Mauritian therapists trained in the protocol, available by video, voice or chat.
