We are all aware of the need for hydration in summer. But few realise that we need to drink adequate fluids in winter as well. Dr Suranjit Chatterjee, senior consultant, internal medicine, Indraprastha Apollo Hospitals, says: “Dehydration is common in winter because people feel less thirsty in cold weather and often forget to drink enough water. Sweating still happens through daily activity, indoor heating, and exercise, but the body does not give strong thirst signals. Cold air also increases fluid loss through breathing, as moisture is lost every time we exhale. Wearing layers and staying in heated rooms can further dry the body. Since people usually reduce plain water intake in winter, dehydration can slowly develop without being noticed, affecting energy levels, digestion, skin health, and overall well-being.”
Beverages like tea and coffee are diuretics, but people keep guzzling them in place of water. What can be alternatives?
Tea and coffee can increase urine output, especially when taken in large amounts, so they should not replace water completely. Better alternatives include warm water, which is gentle and easy to sip through the day. Herbal teas like chamomile, ginger, tulsi, or fennel are good options as they hydrate without strong diuretic effects. Warm lemon water, soups, broths, and vegetable-based clear soups also help maintain fluid balance. Milk and diluted fruit juices can add hydration too. Keeping a bottle of warm water nearby encourages regular intake even when thirst feels low.
Symptoms of dehydration in winter?
Dehydration symptoms in winter are often subtle and easy to miss. Common signs include dry mouth and lips, dark yellow urine, reduced urination, fatigue, headaches, and dizziness. Some people may feel confused, have difficulty concentrating, or experience muscle cramps. Dry skin, itching, and worsening of existing skin conditions are also frequent. Constipation can occur due to reduced fluid intake. Because cold weather masks thirst, these symptoms may appear gradually. Paying attention to urine colour, energy levels, and skin dryness can help identify dehydration early.
Can being dehydrated in winter become dangerous?
Yes, dehydration in winter can become dangerous if ignored. Severe dehydration can affect kidney function, increase the risk of urinary tract infections, and worsen blood pressure control. Older adults, children, and people with chronic illnesses are especially vulnerable. In extreme cases, dehydration can lead to confusion, rapid heartbeat, low blood pressure, and electrolyte imbalance. It can also thicken the blood slightly, raising the risk of clots in susceptible individuals. Regular fluid intake, even without feeling thirsty, is important to prevent these complications and maintain overall health during winter.
