Eyes Wide Open, Immunity Down: The Dangers of Staying Up Late That Are Often Overlooked

In this fast-paced era, staying up late is often considered normal. Working until late at night, binge-watching Korean dramas, or just scrolling through TikTok until 2 AM—everything seems to have become a routine. But did you know? Getting less than 6 hours of sleep per night for a week can decrease your immune system by 30%. It's not a joke.

Sleep is Not Just Rest

When you sleep, your body is actually working hard:

• Repairing damaged cells
• Regulating hormones
• Cleaning toxins from the brain
• Strengthening the immune system

So, sleeping is not laziness—it’s a survival strategy.

Your Immune System Can Drop Without You Knowing

Constantly staying up late makes your body exhausted and vulnerable:

• More susceptible to flu and colds
• Wounds take longer to heal
• Vaccines become less effective
• Increased risk of chronic diseases (diabetes, heart disease, etc.)

Start Fixing Your Sleep Schedule

It doesn't have to be perfect right away, but you can start with small steps:

• Turn off screens 30 minutes before bed
• Sleep and wake up at the same time every day
• Reduce caffeine after 5 PM
• Make your room comfortable and dark
• Do relaxation before bed (deep breathing, journaling, etc.)

Don't Wait Until You’re Sick to Care

Getting enough sleep is the simplest and most important self-care. Start tonight, give your body what it deserves. Because you are strong, but your body also needs rest to keep going.
