Cold weather constricts blood vessels and increases blood pressure, potentially triggering heart attacks, particularly in people with pre-existing cardiovascular conditions: Doctors
As winter tightens its grip, health experts have expressed concerns about heightened risks of heart attacks and also stressed the importance of preventive eye care during the colder months.
With recent studies too showing a notable rise in
heart attack rates during the winter season, the experts said chilling
temperatures and unique seasonal factors contribute to an increased
susceptibility to cardiovascular issues and eye-related complications.
Cold weather constricts blood vessels and increases
blood pressure, potentially triggering heart attacks, particularly in people
with pre-existing cardiovascular conditions, the doctors said.
They advised the public to remain vigilant about heart
health during the winter by maintaining regular exercise, a heart-healthy diet
and staying adequately warm.
Senior consultant interventional cardiologist at the
Ujala Cygnus Group of Hospitals Dr Vijay Kumar said, “It is imperative to
address the heightened risk of heart attacks during the winter season, a
phenomenon attributed to a confluence of environmental factors.”
“The surge in pollution levels during this time not
only triggers inflammation but also intensifies respiratory challenges for
those with pre-existing conditions such as asthma and smokers,” he added.
Additionally, Dr Kumar said, the plummeting temperatures
burden the heart, necessitating increased effort and making individuals more
susceptible to cardiac events.

Dr Abhinit Gupta said the constriction of blood vessels in colder weather poses
a significant threat particularly for hypertensive patients, amplifying the
likelihood of debilitating brain strokes.
“Disturbingly, data reveals a higher mortality rate
post heart attacks in winters as compared to those occurring in the summer
months,” he said.
“However, there is hope in adopting proactive
lifestyle measures to counteract these risks. Regular exercise, moderate eating
habits and proper hydration with lukewarm water can play a pivotal role in
mitigating the vulnerabilities associated with winter-induced heart attacks,”
Dr Gupta added.
“As we navigate the colder months, individuals must
prioritise their cardiovascular health through these practical steps,
empowering themselves to weather the seasonal challenges with resilience and
well-being,” he further said.
Global non-profit organisation Orbis International’s
country director Dr Rishi Raj Borah emphasised the significance of eye care
during winter. Orbis is dedicated to preventing and treating avoidable
blindness.
The winter months present distinctive challenges to
maintaining optimal eye health as dry air, indoor heating and exposure to harsh
winds can lead to dry eyes, irritation, and even more severe conditions, he
said.
“Preventive measures such as staying hydrated, using
artificial tears and protecting the eyes from harsh weather conditions are
crucial to preserving optimal eye health during this season,” Dr Borah added.
According to the experts, regular health check-ups,
adherence to a heart-healthy lifestyle and proactive eye care can make a
significant difference in preventing health complications associated with the
winter season.
