The winter season brings several health challenges ranging from common cold to joint pain. Apart from these, a major health issue that can get exacerbated in the cold weather is the risk of strokes.

According to a 2021 report by ICMR - National Centre for Disease Informatics and Research, stroke was the third leading cause of death and sixth leading cause of disability in India.

Explaining how a stroke is caused, Dr Rahul Jankar, Consultant Neuro Physician and Stroke Specialist, AIMS Hospital, Dombivli, says, "A stroke is a medical emergency that can happen to anyone, anywhere and at any time. In this condition, the blood flow to a specific part of your brain is disrupted. This can further lead to the death of brain cells, which can impair your brain's ability to perform various essential functions."

Given the life-threatening complications caused by this condition, it becomes crucial to understand and recognise risk factors for timely intervention. In a conversation with mid-day.com, Dr Jankar reveals risk factors of stroke during winter months and ways to prevent it.

Common risk factors of stroke during winter season

Hypertension: The coldness in the temperature constricts the blood vessels. This can significantly raise your blood pressure. Your appetite may increase during the winter months, which can lead to eating salty foods. It can further increase the risk of high blood pressure which is known to be the major contributor to the occurrence of stroke.

Reduced physical activity: People rarely step outdoors during the winter, which can lead to a reduced range of motion. This can cause complications like sudden weight gain and poor blood circulation, heightening the chances of experiencing stroke.

Dehydration: The cold weather can make your body lose more water through urine which can lead to dehydration. It can negatively reduce the blood flow to your skin and kidneys. Dehydration can thicken the blood while increasing the risk of clotting. This can disrupt the blood flow to your brain and cause stroke.

Respiratory infections: The winter season is associated with an increased prevalence of respiratory infections, such as the flu and common cold. Infections can trigger inflammation and stress on the cardiovascular system, potentially increasing the risk of a stroke.

Tips to prevent stroke during winter season

Dr Jankar shares the following tips to manage the above risk factors, and maintain a healthy lifestyle.

1. Staying physically active can help improve your blood circulation.

2. Keep your diet clean and healthy. Make informed decisions by avoiding foods that are salty or fatty.

3. Manage your stress levels by engaging in mindful activities like deep-breathing exercises, meditation and things that make you happy.

4. Drink enough water throughout the day to stay hydrated as it helps keep your blood thin while maintaining a smooth blood flow.

5. Monitor blood pressure and blood sugar levels and take medication as recommended by the doctor to prevent a stroke.

6. Getting vaccinated against the flu and practising good respiratory hygiene can help prevent infections.
