A concerned reader has reached out to Doctor Vikatan, expressing worry about the potential health risks associated with working night shifts. The reader, a 39-year-old individual with several years of experience in night shifts, specifically inquires about the increased risk of heart attacks and seeks guidance on preventive measures. Cardiologist Arun Kalyanasundaram, based in Chennai, responds to these concerns.
Kalyanasundaram acknowledges the inherent risks of long-term night shift work, which may not only contribute to heart disease but also increase the susceptibility to conditions such as diabetes, high blood pressure, and obesity.
Recognizing the unavoidable nature of night shift work for many individuals, Kalyanasundaram offers practical advice to minimize the associated health risks. Recommendations include avoiding stimulants like coffee, tea, and cigarettes after the night shift, prioritizing immediate sleep upon its conclusion, wearing sunglasses to protect sleep from sunlight exposure, and creating a conducive sleep environment at home.
The cardiologist emphasizes the importance of maintaining a well-lit workspace during night shifts to promote alertness and prevent sleep disturbances.
Additionally, he suggests establishing a daily exercise routine, ensuring adequate daytime sleep, and considering vitamin D supplements under medical guidance, particularly due to reduced daylight exposure.
Kalyanasundaram advises individuals engaged in night shifts to undergo a comprehensive annual full-body checkup and seek medical attention for any unusual symptoms.
While advocating for a balanced approach to food, sleep, and exercise to mitigate the impact of night shift work, he encourages individuals to avoid unnecessary worry.
