JAKARTA - Walking is known as a simple physical activity that is healthy. However, this habit needs to be done more carefully during the winter, because low temperatures have the potential to put additional pressure on the cardiovascular system.

Quoting Hindustan Times, Senior Director and Head of the Department of Cardiology at Fortis Vasant Kunj Hospital, Dr. Tapan Ghose, explained that morning street activities in winter can increase the risk of heart attacks and strokes. This is related to the narrowing of blood vessels due to cold temperatures which leads to an increase in blood pressure.

"Cold temperatures cause our blood vessels to narrow, which can increase blood pressure and make the heart work harder. This effect is especially felt in the morning when body temperature is lower and the ambient temperature is at its lowest point," said Ghose.

He added that certain groups are at higher risk, especially those with a history of heart disease, uncontrolled hypertension, or a stroke. In this group, the additional burden on the heart can trigger serious health problems.

According to Ghose, the sudden change in temperature from the warm conditions inside the room to the cold air outside can trigger a sudden spike in heart rate and blood pressure.

In addition to temperature factors, environmental conditions in the morning also play a role. The heart specialist reminded that pollution levels tend to be higher in the early hours of the morning, while oxygen levels are lower, so it can increase the pressure on the heart.

However, Ghose emphasized that the level of risk for each individual is not the same. People with good health conditions are generally able to adapt, but those with cardiovascular disorders will find it more difficult to adapt to extreme temperature changes.

Some signs to watch out for and reasons to immediately stop outdoor activities in cold weather include the appearance of discomfort in the chest, unusual shortness of breath, dizziness, and a pounding heart.

"To enjoy safe morning walks in winter, consider warming up gradually indoors before going out, wear layered clothing to keep your body temperature up, and avoid going out too early in the morning when temperatures are at their lowest," Ghose advised.

He also recommends that walking activities be carried out in the middle of the morning, when the air temperature begins to warm, so that it is still possible to get the benefits of exercise without giving an excessive burden on the heart.
