Sleeping with the TV on may silently harm your health, neurologist warns
A Russian neurologist has warned about the dangers of falling asleep with the television on. Tatiana Khrebtova highlighted how background noise and flickering screens disrupt sleep, posing serious risks to long-term health. Her comments were shared by Khabarovsk Territory Today, referencing a report from RIA Novosti. Khrebtova explained that TV noise causes micro-arousals—brief awakenings that break sleep continuity. These interruptions, though often unnoticed, prevent the body from fully resting. Over time, they can raise blood pressure and blood sugar levels, increasing the risk of chronic conditions.
The flickering light and changes in screen brightness trigger a stronger brain response than steady, dim lighting. This reaction can lead to chronic low-grade inflammation in the body. People with existing health issues, such as hypertension, diabetes, or sleep apnoea, face even greater risks. Despite the warnings, no global studies have measured the exact impact of TV-induced micro-awakenings on sleep quality or cardiovascular health. A 2022 review of 34 studies explored soundscapes like white noise for better sleep but did not examine TV noise or its link to heart disease.
The neurologist's warning underscores the potential harm of sleeping with a television on. Prolonged exposure to such disruptions may heighten the risk of stroke and other cardiovascular problems. Those with pre-existing health conditions are advised to be particularly cautious about this habit.
