TikTok's algorithm may be activating you like a slot machine and disrupting sleep, an expert says

A ResMed survey found 53% of respondents reported good sleep at most four nights a week, and Dr. Carlos Nunez said TikTok's algorithm can trigger dopamine spikes that make it harder to fall asleep.

Most people report inconsistent sleep, according to a recent ResMed survey that the article highlights during Sleep Awareness Week 2026. The survey found that 53% of respondents get a good night's sleep at most four nights a week. Dr. Carlos Nunez of ResMed is quoted describing how apps such as TikTok can produce dopamine-driven activation that delays falling asleep. The piece outlines common barriers to regular rest and summarizes expert observations and reported guidance. Key points: - The ResMed survey reported that 53% of respondents get a good night's sleep at most four nights a week, while fewer than one-third said they sleep well every night. - Stress and anxiety were cited by 39% of survey respondents as contributors to poor sleep; work and household responsibilities were also named among common barriers. - Use of electronic devices before bed was reported by 21% of respondents, and Dr. Nunez is quoted saying the TikTok algorithm "is activating you like a slot machine," producing dopamine spikes that can keep people awake. - The article notes that sleep disorders such as sleep apnea may be common and underdiagnosed (the piece cites estimates of around 30 million people in the US with sleep apnea and about six million diagnosed), and it reports expert discussion of routine-focused approaches and clinical evaluation. Summary: The article reports a widespread gap between awareness of sleep's importance and regular sleep practice, and it highlights technology-driven stimulation and undiagnosed sleep disorders as contributors. Experts quoted in the article describe routine and environmental approaches and clinical assessment as relevant topics in addressing sleep problems. Undetermined at this time.
