📍Have You Ever Thought Why You Scroll at 2 AM But Still Can’t Sleep?

I’ve seen my own cousin toss and turn every night. And guess what? He’s not alone. In India, over 93% of young adults use mobile phones before bed, and many of them experience delayed sleep or poor sleep quality.

We blame stress. We blame coffee.
But the real culprit might be hiding... in your screen.

Let’s talk about blue light – the invisible disruptor messing with our sleep, hormones, and health.

🔵 What Is Blue Light?

Blue light is a high-energy visible light (HEV) emitted by:

• Smartphones 📱
• Laptops 💻
• LED TVs 📺
• Fluorescent lights 💡

Naturally, the sun also emits blue light – but the problem starts when we get too much of it after sunset.

😴 How Does Blue Light Affect Sleep?

Here's the science (don’t worry, I’ll keep it human):

🧠 Your brain releases a hormone called melatonin, which makes you sleepy.
But blue light suppresses melatonin, tricking your brain into thinking it’s still daytime.

Result?
You stay alert, fall asleep late, or wake up tired.

📌 A 2023 AIIMS-supported study showed that people exposed to screens for more than 3 hours after 8 PM had significantly lower melatonin levels and took longer to fall asleep.

🚨 Common Signs You're Affected

• You feel tired but can’t sleep
• You wake up in the middle of the night
• You feel groggy or irritated in the morning
• Headaches or eye strain at night
• Dependence on tea/coffee next morning ☕

Sound familiar?

💡 Who’s At Higher Risk in India?

• Students (online classes + late-night study)
• Office workers (WFH culture = screen overload)
• Teens & influencers (scrolling reels till 3 AM)

Even 8-year-olds using tablets are showing early signs of delayed sleep phase disorder.

✅ How to Protect Your Sleep Naturally

As a pharmacy student, I suggest prevention before prescription. Here’s what actually works:

1. 🌙 Follow the “Screen Sunset Rule”

• Reduce screens 1–2 hours before bed
• Use yellow light instead of white/blue light bulbs

2. 🕶 Use Blue Light Filters

• Turn on “Night Mode” on all devices
• Try blue light-blocking glasses

3. 🧘 Try a Sleep Wind-Down Ritual

• Herbal teas (like chamomile)
• 10 mins of deep breathing
• Listen to calming music (not scroll TikTok!)

4. ⏰ Fix Your Sleep Cycle

• Sleep/wake at the same time daily
• Limit naps to 20–30 minutes

5. 🍽 Avoid These Before Bed

• Spicy or heavy food
• Excess sugar
• Too much water (yes, bathroom trips wake you up!)

Q2. Is melatonin safe to take for sleep?

Melatonin supplements can help but should be used only if natural methods fail. Always consult a doctor before use.

🧠 Final Thoughts: The Silent Sleep Killer

Your screen isn’t evil. But your habits around it can be.

📵 Sleep isn't just about rest. It’s your body’s way of resetting. Don’t let blue light rob your recovery.

👉 Try one small change tonight – maybe reading a book instead of binge-watching. Trust me, your body will thank you tomorrow.
