What causes drowsiness when watching TV?
Generally, feeling sleepy when watching TV may be caused by reduced visual stimulation, circadian rhythm influence, distraction, sleep disorders, depression, and other factors. It is recommended to seek medical advice promptly and receive symptomatic treatment under the guidance of a physician. Specific analysis is as follows:
1. Reduced Visual Stimulation
When watching TV, especially for prolonged periods staring at the screen, visual stimulation gradually decreases, causing the brain to enter a relaxed state, which can easily induce drowsiness. Take regular breaks—after every 30 minutes to one hour of viewing, stand up, move around, and look into the distance to reduce visual fatigue.
2. Circadian Rhythm Influence
When watching TV at night, blue light emitted from screens may interfere with the body's circadian rhythm and affect melatonin secretion, making individuals feel sleepier. Minimize exposure to blue light in the evening and avoid using electronic devices before bedtime.
3. Distraction of Attention
During prolonged TV watching, particularly when the content is monotonous or unengaging, attention tends to wander, leading to decreased brain activity and subsequent drowsiness. Choose programs that are interesting or educational, or schedule short breaks to avoid watching TV continuously for long periods.
4. Sleep Disorders
Sleep disorders are usually caused by long-term psychological stress, mental overwork, and similar factors, resulting in poor sleep quality and daytime drowsiness. When watching TV in a relatively quiet environment, it becomes easier to fall asleep. Symptoms may also include excessive daytime sleepiness and difficulty concentrating. Under medical supervision, medications such as Zaoren Anshen Capsules, Baille Mian Capsules, or Jieyu Anshen Granules may be used for treatment.
5. Depression
Depression is generally associated with chronic high-pressure states and other factors. Patients often experience sleep disturbances and reduced energy levels, making them prone to drowsiness while watching TV due to lack of interest or low energy. Symptoms may also include low mood and loss of interest. Under a doctor’s guidance, patients may take medications such as maprotiline hydrochloride tablets, clomipramine hydrochloride tablets, or paroxetine hydrochloride tablets.
When watching TV, try to limit viewing time, get up and move periodically, ensure good indoor ventilation, and avoid maintaining the same posture for extended periods to prevent drowsiness.
