Television in bedroom linked to poorer sleep quality

Health specialists warn that keeping a television in the bedroom can impair sleep. Psychologist Oceanía Martín notes that many people believe the TV helps them fall asleep, but the brain still processes the visual and auditory stimulus, disrupting the natural transition to rest. The presence of screens interferes with circadian rhythms and can delay sleep onset, especially when combined with bright light and stimulating content.

Researchers also point out that mobile phones and tablets pose an even greater risk because of their proximity to the user. Marta Calderero of the UOC observed that "the closeness of a mobile phone in the minutes before sleep is far more harmful than television." Experts recommend restoring the bedroom to a sleep‑only environment: remove the TV, avoid devices in the hour before bedtime, and adopt calming routines such as reading a paper book or practicing breathing exercises.

These measures aim to improve sleep hygiene, reinforce the association between the bedroom and rest, and protect the body’s biological clock.
