Will you risk developing high blood pressure if you talk on the phone for too long? Research reveals: Risk increases by more than 20% after 6 hours of talking on the phone
Using a smartphone is not only easy to hurt your eyes, but may also cause high blood pressure? A recent study published in the “Journal of the European Society of Cardiology”, a publication of the European Society of Cardiology (ESC), pointed out that talking on a mobile phone for 30 minutes per week is associated with a 12% increase in the risk of hypertension; if the call time increases to 6 hours per week, The risk will increase to 25%, raising concerns about cardiovascular health.
Are you worried about high blood pressure if you talk on the phone for too long? Study reveals: Risk increases by 25% after 6 hours of talking on the phone
A research team from China Southern Medical University analyzed the health status of 212,046 British people through data from the UK Biobank. The average age of the subjects was 37-73 years old, and the average age was 54 years old. In this study, mobile phone users were defined as “those who make or receive calls at least once a week,” accounting for 88% of the total.
The research team used questionnaires to obtain information such as the age of telephone use of the subjects, the number of hours of use per week, and whether they used hands-free phones. They conducted random interviews over 12 years and found that 13,984 (7%) subjects Patients suffered from hypertension during the follow-up period. The analysis results show that compared with non-mobile phone users, mobile phone users have a 7% increased risk of high blood pressure; those who use mobile phones for more than 30 minutes a week have a 12% increased risk of high blood pressure than those who talk for less than 30 minutes, and the risk of high blood pressure among men and women is The results are similar.
Further analysis of the study results found that compared with subjects who made or answered mobile phone calls for less than 5 minutes per week:
Those who talked for 30-59 minutes per week had an 8% increased risk of high blood pressure.
People who talk on the phone for 1-3 hours a week have a 13% increased risk of hypertension.
People who talk on the phone for 4-6 hours a week have a 16% increased risk of hypertension.
People who talk on the phone for 6 hours or more per week have a 25% increased risk of high blood pressure.
In addition, among subjects with high genetic risk, using mobile phones for at least 30 minutes a day increased their risk of developing hypertension by 33%. Compared with smartphone users, use of hands-free devices or hands-free phones was not significantly associated with the prevalence of hypertension. Previous studies on the relationship between cell phone use and blood pressure have had mixed results, possibly due to the effects of calls, messages and games.
Why is call duration related to blood pressure? Experts speculate on three potential reasons
Professor Qin Xianhui, the lead author of the study, said: “Our findings indicate that keeping the time spent talking on mobile phones to less than half an hour per week may lower the risk of hypertension than talking on the phone frequently.” She said that the amount of calls people spend on mobile phones The longer the duration, the greater the cardiovascular risk. As for the correlation between the two, more research is needed to prove it.
What are the potential causes of hypertension caused by mobile phones? The research team of China Southern Medical University speculates that it may be related to the following reasons:
How to hold the phone. Raising the forearm, holding the phone tightly with the dominant hand, and maintaining a static posture for a long time may increase sympathetic nerve activity and increase the level of adrenaline in the blood, thereby affecting blood pressure. However, there is no significant correlation between the use of hands-free phones and the risk of new-onset hypertension. Therefore, whether the posture in which the phone is held affects blood pressure values requires further exploration.
Affect sleep quality. Frequent cell phone or mobile device use may be associated with adverse mental health consequences and sleep disturbances, both of which can cause damage to blood vessels and increase blood pressure.
The influence of electromagnetic waves. “Radio frequency electromagnetic waves” (RF-EMF) emitted by mobile devices can easily cause harmful effects on body cells, including DNA damage, oxidative stress, and body inflammation, all of which are potential pathogenesis mechanisms of hypertension. Previous single-blind placebo-controlled studies have also noted that exposure of the right hemisphere to RF-EMF for approximately 35 minutes was associated with a 5-10 mmHg increase in systolic blood pressure.
In addition, China Southern Medical University pointed out that due to the increase in oxidative stress in the subjects, as well as DNA materials and cell apoptosis, the longer the number of hours of mobile phone use per day may be negatively correlated with sperm concentration and total number, and this phenomenon is caused by Caused by RF-EMF radiation. Therefore, whether the reduction in sperm quality caused by mobile phone use will affect male fertility and the health of future generations deserves in-depth discussion by the academic community.
