A recent study published in BMC has linked late-night screen time, especially watching short videos on platforms like Instagram Reels and TikTok, to an increased risk of hypertension in young and middle-aged adults. The study, which involved 4,318 participants, found that more time spent on these videos before bed was associated with higher blood pressure levels.

Dr. Deepak Krishnamurthy, a cardiologist in Bengaluru, emphasized the potential health risks of this behavior. He noted that addiction to short videos not only serves as a major distraction but can also contribute to raising blood pressure. He advised limiting the use of apps that encourage late-night screen time to reduce this risk.

The study found that the sedentary nature of watching short videos, as opposed to traditional screen time activities like watching TV or playing video games, plays a significant role in exacerbating health issues like hypertension. While traditional screen activities often involve slight physical movements, watching short videos is typically a more passive activity that encourages less movement and can be harmful to overall health.

Watching emotionally charged or exciting content may activate the sympathetic nervous system, triggering a "fight-or-flight" response, which results in increased heart rate and elevated blood pressure. Since many people remain inactive while viewing these videos, relaxation is minimized, leading to a heightened physiological response that can contribute to the development of hypertension.

The research team, which included Fengde Li, Fangfang Ma, Shangyu Liu, Le Wang, Lishuang Ji, Mingqi Zheng, and Gang Liu from Hebei Medical University, recommended several strategies to reduce the risk of hypertension. They urged the public, especially young people, to limit their screen time before bed. This simple adjustment not only helps prevent hypertension but also promotes better sleep hygiene and overall health.

The researchers also highlighted the importance of maintaining a healthy lifestyle, including regular physical activity, proper nutrition, and effective stress management. These measures can contribute to lowering the risk of hypertension and improving general well-being.

In conclusion, the study provides a crucial reminder of the health risks associated with excessive late-night screen time, urging the public to be mindful of their habits to safeguard their long-term health.
