Running is a popular sport , but is it still a good idea to run in cold weather?
For many people, jogging or exercising early in the morning is a fairly regular habit. Under normal weather conditions, this is a good habit, allowing people to get some light exercise to create a feeling of freshness and relaxation, preparing them for a new workday.
However, if you practice this habit in winter, especially on cold days when the outdoor temperature drops low, it can easily lead to a stroke and negatively impact your health.
Speaking to Gia Dinh Viet Nam (Vietnamese Family) newspaper , Dr. Doan Du Manh, a member of the Vietnam Vascular Disease Association and Deputy Director of the Cardiovascular and Stroke Center at Phuong Dong General Hospital, said that exercising and jogging are good ways to protect the body and boost immunity. However, improper exercise can cause harm, even life-threatening conditions.
In particular, Hanoi has recently been continuously shrouded in fine dust, ranking among the world's worst air pollutants . Exercising in polluted air further increases the risk of respiratory illnesses, as people inhale more polluted air.
Dr. Manh also added that, besides respiratory illnesses, the cold season is also when the rate of stroke increases by 20-30% compared to other seasons.
This is especially true for the elderly and those with underlying conditions such as high blood pressure, diabetes, or cardiovascular disease. Therefore, doctors always warn that the cold season is a time when strokes are more likely to occur.
"In cold weather conditions, improper exercise can cause strokes in all age groups," said Dr. Manh.
The doctor explained that in the early morning, while the body is warm under a blanket, people immediately go out into the cold, polluted air to exercise, leading to inhaling more harmful gases than usual. This can cause blood vessels to constrict suddenly, resulting in increased blood pressure, cardiovascular events, and strokes.
In particular, early morning is when the body is at rest and the blood is more concentrated. If blood pressure rises at this time due to exposure to cold air, it increases the risk of cerebral hemorrhage (brain bleeding) or thrombotic blockage.
"With the current cold weather and air pollution, people should avoid jogging or cycling outdoors, especially in the early morning and late evening, as these are the coldest and most polluted times," Dr. Manh advised.
Therefore, to ensure good health during cold weather, Doctor Manh advises people to choose indoor sports instead. Outdoor exercise should only be done when the weather is warm and the air is fresh.
"Exercising is good for improving health, but we need to protect our bodies. Don't ruin our lungs and hearts because of air pollution," the doctor advised.
If you must run outdoors, dress warmly to ensure your body doesn't get cold. Additionally, warm up thoroughly before going outside and wear a face mask to protect against fine dust.
According to the National Center for Meteorological and Hydrological Forecasting, on February 7th, the weather in Northern Vietnam will be intensely cold, with severe frost; from the night of February 7th, the North Central region will experience intensely cold weather, and the area from Quang Binh to Hue will experience cold weather, with some places experiencing intensely cold weather.
The lowest temperatures during this cold spell in Northern Vietnam will generally range from 9-12 degrees Celsius, 5-8 degrees Celsius in mountainous areas, and below 3 degrees Celsius in some high mountainous regions.
