**TikTok Habits Disrupting Sleep Science Experts Warn**
(TikTok And The Science Of Sleep)
NEW YORK CITY, NY – Popular video app TikTok is changing how people sleep. Many users watch TikTok videos late at night. This habit makes falling asleep harder. Scientists explain why this happens.
Smartphone screens emit blue light. This blue light tricks the brain. The brain thinks it is still daytime. This stops the body from making melatonin. Melatonin is the chemical that makes us sleepy. Less melatonin means struggling to fall asleep.
TikTok videos are also very short and fast. People swipe quickly to the next clip. This keeps the brain highly active and alert. An active brain does not relax easily for sleep. Doctors see more young people reporting poor sleep. They link this to late-night social media use.
Dr. Sarah Chen studies sleep at City University. She sees a problem. “Endless scrolling on TikTok excites the brain. It prevents the natural wind-down before sleep. People need calm activities before bed.” She advises users to stop using phones an hour before sleep.

Others suggest setting a phone bedtime alarm. This alarm reminds users to put the device away. Reading a book or listening to quiet music is better. These activities help the mind relax. Good sleep is vital for health and mood. TikTok is fun but needs limits for better rest.
