Think bedtime scrolling is relaxing? It could lead to hypertension, study finds; Indian doctors concurAn informative article prepared by @chetanabelagere published in @TheSouthfirst , which has my quotes alongside that of other experts.

Neuro and heart effects also seen
"Dr Sudhir Kumar, consultant neurologist at Apollo Hospital, told South First, “This association was dose-dependent, meaning those who spent more than four hours watching videos at bedtime had a higher risk—40 times higher—of hypertension compared to those who watched videos for three to four hours, whose risk was nine times higher.”

"He explained possible reasons for the increased hypertension risk with prolonged video watching, including more sedentary time and sympathetic arousal, depending on the content of the videos."

"Dr Kumar added that exposure to screens (via mobile phones, laptops, or TVs) at bedtime negatively impacts sleep quality and duration."

"This includes increased sleep latency (time taken to fall asleep after turning off the lights), frequent awakenings, shorter sleep duration, and not feeling refreshed upon waking."

“Poor sleep, in turn, is linked to a higher risk of being overweight, obesity, type 2 diabetes, hypertension, cardiovascular diseases, and some types of cancer.

"Excessive screen exposure close to bedtime can also increase stress and anxiety, depending on the content being watched. Watching a mobile screen in a dark room has even been reported to cause transient (short-duration) blindness,” he said.

"Dr Sudhir Kumar, however, emphasised that the study only shows an association, adding, “More well-designed research is needed to confirm these observations.”
