As winter sets in with full force, hydration is often the last thing on our minds. The first month of the year brings cold, dry weather, which makes thirst feel non-existent. Even though so many people think of dehydration as something that only occurs in hot weather, doctors tell us that the problem during winter months is much more widespread than one imagines. However, the only difference is that it often remains undetected until symptoms begin to show.
According to our expert, Dr Pooja Pillai, Consultant – Internal Medicine, Aster CMI Hospital, Bangalore, the water loss of the body during winter goes unnoticed because one of the body’s functions responsible for feeling thirsty diminishes in cold weather. “Thirst is one of the body’s signals to drink enough water, and it is less active during winter in the case of most people who sweat less. Even though the body loses less water through perspiration, it still loses water through breathing, urine, and dry air absorption. Regular intake of water, even when you don’t feel thirsty, is the only way to keep dehydration at bay during winter," she explained.
Causes of Winter Dehydration
Cold air is dry, and indoor heating further strips moisture from the environment. Every time we inhale, our body loses some moisture, and frequent urination, also known as cold-induced diuresis, is another factor contributing to fluid loss. On top of that, wearing too many clothes, reduced physical exertion, and having fewer water breaks make it very easy to become dehydrated without noticing.

The symptoms of dehydration first show very mildly, for example, dry lips, dull skin, headaches, fatigue, less urination and dark-coloured urine. Many people confuse these with winter tiredness instead of dehydration.
What Is the Sure-Shot Hydration Technique?
The best way to ensure proper water intake in January is to keep hydrating regularly. According to Dr Pillai, the winter months are not the time to depend on the thirst signal as the only indicator of hydration. Rather, it should become a habit.
“At the beginning of the day, drink a glass of warm water. This will slowly wake up your digestive system and also indicate the time for a regular intake of fluids. Instead of taking a large drink all at once, drink small amounts throughout the day. Having a water bottle within reach is a simple way to remind you visually,” she recommended.
“Warm Fluids Make Hydration Easier.”
Even though cold water might not be very inviting in winter, do not limit yourself to plain water as the only source of hydration. Warm fluids do not just comfort you but are also equally effective in hydrating. Herbal teas, clear soups, warm lemon water, and traditional broths not only help to maintain the fluid balance but also soothe the throat and the digestive system.
“Regular consumption of these beverages can make it easy to obtain the daily hydration requirements without having to drink cold drinks,” Dr Pillai suggested.
How To Enhance Hydration in Winter
Hydration is not only through ingested liquids. Fruits and vegetables are also a prime source of a day’s fluid intake. Fruits and seasonal vegetables are very high in water content. Dr Pillai added that seasonal fruits, cooked vegetables, soups, dals, and stews help support hydration while providing essential nutrients.

This is also because foods that contain natural water and moisture also help maintain the balance of electrolytes, which is particularly important for winter energy levels and muscle function.
Importance of Monitoring Dehydrating Practices
Tea, coffee, and alcohol in excess can result in fluid loss, and this occurs more during winter when the body is already losing moisture to the cold. “You do not have to cut them altogether, but have to consume them in moderation. For every cup of caffeine or alcohol, you should drink water or a hydrating warm beverage to counter that,” Dr Pillai said.
Bottomline
Dehydration in winter is real, and the most effective way to prevent it is very simple. Experts recommend drinking water at regular intervals, sipping warm fluids, eating water-rich foods, and not waiting until you feel thirsty.
