Hydration keeps body temperature stable. Lack of fluid in the body can cause the core temperature to drop to dangerous levels.
Low body temperature can dull skin and lower immunity- staying hydrated helps our immune system fight colds and flu and gives skin a natural glow.
Individuals with low immunity are more prone to colds and flu in winter. Eating a balanced diet is essential for boosting immunity. Have pulses, legumes, whole grains, lean meat, poultry, fish, nuts and seeds, spices and herbs, and plenty of fresh fruits and vegetables.
Take foods rich in vitamin C (citrus fruits) since they strengthen our immune system and keep the body healthy. Foods that keep the body warm in winter include corn, pearl millet, jaggery, eggs, mustard leaves, and herbs.
Vitamin D is essential for bone health and immunity. During winter, it may not be possible to get adequate sun exposure due to multiple layers of clothing. Have a vitamin D-rich diet to get enough sun exposure, and take supplements if you have a vitamin D deficiency.
Winter can be more severe for heart patients. The cold temperature causes blood vessels to contract, raising blood pressure, putting pressure on the heart, and increasing the risk of heart attacks and stroke.
Health problems such as asthma, flu, sore throat, and painful joints are also more prevalent in cold weather. A preventive health checkup is the best way to avoid winter illnesses and maintain good health even in cold weather.
Smoking is dangerous in any weather but is especially harmful in winter- cold air and smog harm the lungs, and smoking worsens it, causing swelling and narrowing of the lung airways, resulting in shortness of breath.
