Smoking and its effects on heart rate variability

Due to smoking's widespread prevalence, it is necessary to explore cost-effective and practical prognostic markers indicating its health effects. Heart rate variability (HRV) may be used to foresee the long-term repercussions of smoking as a simple and affordable approach of forecasting cardiovascular health complications. Smoking has been proven to have a detrimental effect on HRV, which may have a detrimental effect on cardiovascular health. Additionally, we present an overview of the different HRV measurements and their diagnostic utility in the context of heart failure. There is a very detailed look at all the available data on how smoking affects HRV, as well as how different HRV indices show changes in the activity of the body's autonomic nervous system when people smoke. Smoking has been shown to change the autonomic nervous system's normal function, including an increase in sympathetic drive, a decrease in HRV, and a decrease in parasympathetic control. The possible reasons for this decrease in HRV and how it might affect patients are thoroughly discussed

COVID-19 and the effect of its infodemic on people’s wellbeing

In this research, it was used to look at social media behaviour during the pandemic and how it might have affected well-being. The WHO-5 Well-Being Index (WHO-5) score was used to do this. COVID-19-related material was sought for and disseminated through social media by those who participated in the study. This research shows how social media might affect people's well-being during this epidemic and other crisis in the future. 73 percent of the 993 participants were women, 91 percent were university graduates, and 50 percent worked in diverse occupations, with 20 percent working in health care. Participants said they got COVID-19-related news mostly via social media and messaging apps, with WhatsApp being the most popular. After authentication, the majority of participants said they shared information. Throughout the coronavirus pandemic, this research offers insight into the usage of Social Media and its influence on well-being. During catastrophes and disasters, social media behaviours may have an influence on public safety. There is also a need for global and local health authorities to better prepare for future challenges by developing policies and actions that address these difficulties. Social media activities may directly affect one's mental health, but more research is required before conclusions can be drawn
