Understanding Insomnia: Causes and Solutions
Updated: Sep 21
What Exactly Is Insomnia?
Insomnia isn't just one thing. It's a symptom, not a diagnosis. Broadly speaking, it falls into a few categories:
Difficulty falling asleep: You lie awake for 30 minutes or more before drifting off.
Difficulty staying asleep: You wake up multiple times during the night and struggle to get back to sleep.
Early morning waking: You wake up at 3 AM or 4 AM and can't fall back asleep, no matter how tired you are.
Non-restorative sleep: You sleep a full 7-8 hours but wake up feeling exhausted, as if you didn't sleep at all.
Some people experience one type of insomnia, while others may have several. For many, insomnia is a short-term problem lasting days or weeks. However, for others, it can be chronic, lasting months or even years.
The good news? Most insomnia can be treated without sleeping pills, often through simple changes to your daily habits. For cases that need more help, an online GP can guide you through the options.
Why Can't I Sleep?
Insomnia rarely happens for no reason. Something usually triggers it. Here are the most common culprits:
1. Stress and Anxiety
This is the biggest factor. Work pressure, money worries, relationship struggles, and health concerns can keep your brain on high alert. When your brain senses danger, sleep becomes secondary. You might notice racing thoughts when your head hits the pillow, replaying conversations, or worrying about tomorrow.
2. Poor Sleep Habits (Sleep Hygiene)
Our bodies thrive on routine. Irregular bedtimes, late-night screens, caffeine after lunch, or weekend sleep-ins can confuse your internal clock. Common habits that wreck sleep include:
Scrolling on your phone in bed (blue light suppresses melatonin)
Drinking coffee or tea after 3 PM
Eating heavy meals right before bed
Napping for hours during the day
Sleeping in on weekends to "catch up"
3. Medical Conditions
Many health problems interfere with sleep, including:
Chronic pain (arthritis, back pain, fibromyalgia)
Acid reflux (heartburn worsens when lying down)
Asthma or allergies (breathing difficulties worsen at night)
Restless legs syndrome (uncomfortable sensations causing an urge to move)
An overactive thyroid
Menopause (hot flushes and night sweats)
If you have an underlying condition, treating it often alleviates insomnia.
4. Medications
Some medications can keep you awake, such as:
Certain antidepressants
Steroids (like prednisone)
Decongestants (common in cold and flu medications)
Stimulants for ADHD
Some blood pressure medications
If you started a new medication and your sleep deteriorated, that's a clue.
5. Mental Health Conditions
Depression, anxiety disorders, bipolar disorder, and PTSD are strongly linked to sleep problems. In fact, insomnia is often one of the first signs of depression.
6. Caffeine, Alcohol, and Nicotine
Caffeine blocks the chemical that makes you feel sleepy. Its effects can last 8-12 hours.
Alcohol might help you fall asleep, but it fragments your sleep later in the night, leading to early waking.
Nicotine is a stimulant. Smokers often wake up early because their body craves nicotine.
What You Can Do Tonight
Before reaching for sleeping pills, try these evidence-based strategies:
1. Stick to a Schedule (Even on Weekends)
Go to bed and wake up at the same time every day, even on Saturdays. Your internal clock craves consistency.
2. Make Your Bedroom a Sleep Sanctuary
Keep it cool (18-20°C is ideal).
Keep it dark (blackout curtains or an eye mask).
Keep it quiet (earplugs or white noise if needed).
No screens in bed. No TV, no phone, no laptop.
3. Create a Wind-Down Routine
Thirty minutes before bed, do something calming:
Read a physical book (no screens).
Take a warm bath or shower.
Listen to calm music or a sleep podcast.
Try gentle stretching or deep breathing.
4. Get Out of Bed If You Can't Sleep
This might sound counterintuitive, but it works. If you've been lying awake for 20-30 minutes, get up. Go to another room and do something boring (like reading a book or folding laundry). Return to bed only when you feel sleepy. This helps break the association between bed and frustration.
5. Cut the Caffeine and Alcohol
Try to avoid caffeine after 2 PM. If you drink alcohol, stop at least 3 hours before bed.
6. Move Your Body (But Not Too Late)
Regular exercise improves sleep quality. However, intense exercise within 2-3 hours of bedtime can keep you wired. Morning or afternoon walks, jogs, or gym sessions are ideal.
When to See a Doctor About Your Sleep
You can try all the tips above, and sometimes they aren't enough. That's not your fault. Insomnia can be stubborn.
Consider seeing an online GP if:
Your sleep problems have lasted more than a month.
You've tried good sleep hygiene, and nothing has changed.
Your insomnia affects your mood, work, or relationships.
You feel hopeless or anxious about sleep.
You have other symptoms (pain, racing heart, night sweats, breathing problems).
How an Online GP Can Help With Insomnia
An online doctor can't examine you in person, but for insomnia, that's often fine. We can:
Take a detailed sleep history (what's happening, when it started, what makes it better or worse).
Identify possible underlying causes (medications, medical conditions, mental health).
Recommend specific sleep hygiene strategies tailored to your life.
Prescribe short-term sleep aids if appropriate (and explain the risks).
Prescribe a natural sleep hormone available by prescription in South Africa.
Refer you to a therapist who specializes in CBT-I (Cognitive Behavioral Therapy for Insomnia) – the gold-standard non-drug treatment.
Order blood tests to check for medical problems that might be causing sleep loss.
Provide a sick note if you're too exhausted to work.
And you can do it all from your couch – no waiting rooms, no commuting, no taking hours off work.
A Note About Sleep Medications
Sleeping pills are not evil. They can be helpful for short-term use (a few days to a few weeks). However, they come with risks: dependence, daytime drowsiness, falls in older adults, and withdrawal insomnia when you stop. An online GP can prescribe a limited course of medication if appropriate, but we'll always focus on fixing the root cause – not just masking the symptom.
You Deserve Restful Sleep
Sleep isn't a luxury. It's a biological necessity. It affects your mood, immune system, heart health, weight, and ability to think clearly. If you're struggling with insomnia, please don't suffer in silence. Help is available – without you leaving your home.
