Good sleep is not a luxury — it's a medical necessity. Learn how to sleep better and when to seek help.
Sleep is not "doing nothing." During sleep, your brain performs critical maintenance:
During deep sleep, the brain's "cleaning system" removes toxins and waste products that build up during the day.
What you learned today gets "saved" during sleep — like pressing CTRL+S on a computer.
Hormones for growth, repair, and immunity are released during sleep. Healing happens fastest during rest.
Imagine your brain is a smartphone. During the day, the battery drains as you use apps (thinking, working, emotions). Sleep is when your brain charges back to 100%. If you only charge to 50% (poor sleep), you'll run low by afternoon — that's fatigue, irritability, poor concentration. Chronic under-charging damages the battery itself (brain health).
A normal night cycling through these stages every 90 minutes:
Drifting off. Easy to wake up. Muscles relax. The door between wakefulness and sleep.
Heart rate slows, body temperature drops. This stage makes up about 50% of your night.
The "golden" stage. Hardest to wake up from. Body repair, immune boost, brain cleaning happens here. Most important for physical health.
Rapid Eye Movement. Vivid dreams occur. Critical for emotional processing, creativity, and memory. Brain is very active.
Difficulty falling asleep or staying asleep. Most common sleep complaint. Often caused by stress, screen time, irregular schedule, or poor sleep habits.
Breathing stops repeatedly during sleep. Causes loud snoring, gasping, unrefreshing sleep, and morning headaches. Increases risk of BP, heart disease, and stroke.
Uncomfortable urge to move legs, especially at bedtime. Described as "crawling," "tingling," or "pulling" sensation. Worse at rest, better with movement.
Falling asleep during the day even after adequate sleep. Could be due to sleep apnea, narcolepsy, or other neurological conditions. Needs evaluation.
In severe sleep apnea, the throat closes shut hundreds of times per night. Each time, your brain briefly wakes up (you don't realise it) to open the airway. It's like someone gently shaking you awake every minute — no wonder you feel exhausted! This also strains the heart and raises blood pressure. A sleep study can diagnose it.
Before any sleeping pill, try these changes consistently for 2–4 weeks:
| Age Group | Recommended Hours | Notes |
|---|---|---|
| Infants (4–12 months) | 12–16 hours | Including naps |
| Children (1–5 years) | 10–14 hours | Including naps |
| Children (6–12 years) | 9–12 hours | Critical for growth & learning |
| Teenagers (13–18) | 8–10 hours | They naturally shift to late sleep — biology, not laziness |
| Adults (18–64) | 7–9 hours | Most people need 7–8 hours |
| Older Adults (65+) | 7–8 hours | Sleep may become lighter; that's normal |
Sleeping pills should be the last resort, not the first. Many people become dependent on them. They should be taken only under a doctor's supervision and for the shortest possible time.
Quantity ≠ Quality. You may have sleep apnea (check: do you snore? are you overweight? do you feel unrefreshed?), or fragmented sleep (waking up multiple times without realising). Stress, medications, and medical conditions can also cause this. A sleep study can help diagnose the issue. CPAP (Continuous Positive Airway Pressure) is the primary treatment for moderate-to-severe sleep apnea — it is a mask worn at night that keeps the airway open, dramatically improving sleep quality and reducing health risks.
Not exactly. Older adults still need 7–8 hours. But sleep becomes lighter and more fragmented with age — they may wake up earlier or have trouble falling back asleep. This is normal ageing. However, it should not be ignored if it causes daytime tiredness.
Melatonin is a hormone your body naturally makes. It's generally safe for short-term use (jet lag, shift work). However, it's not a sleeping pill and doesn't work for all types of insomnia. Dose and timing matter. Always consult your doctor before using it, especially for children.
Very bad for their brain. Blue light suppresses melatonin. Exciting content keeps the brain wired. Studies show that children who use screens before bed take longer to fall asleep, sleep less, and have worse academic performance. The rule: NO screens 1 hour before bed. Charge phones OUTSIDE the bedroom.
Absolutely! Sleep deprivation is a major trigger for migraine and tension headaches. Both too little AND too much sleep can trigger headaches. Maintaining a consistent sleep schedule (same time daily) is one of the most effective headache prevention strategies.
Cognitive Behavioural Therapy for Insomnia (CBT-I) is the gold-standard treatment for chronic insomnia — and it works better than sleeping pills in the long run with no side effects. It combines sleep restriction therapy, stimulus control, relaxation techniques, and correcting unhelpful thoughts about sleep. It is delivered by a trained therapist over 6–8 sessions. Unlike pills, the benefits are lasting. Ask your doctor if a structured sleep therapy programme is right for you.
Sleep, stress and migraine form a tight triangle — fixing one helps the others:
