A runny nose, dry skin and the winter flu may come to mind when thinking of the most common cold season health concerns, according to express.co.uk.
Dehydration is often disregarded as a summer-only issue. As we expect to sweat more in warmer months, we're more likely to carry a water bottle and take other precautions to avoid the condition.
But dehydration is just as likely to strike in the colder months, especially during exercise warns nutritionist Amy Morris.
She explained: "The winter air is drier which makes your lungs work harder to humidify the air and warm it up. The harder your body works, the more you need to hydrate. Often people don't recognize the signs of dehydration in winter, which makes it more dangerous."
According to Amy, there are a few key signs of winter dehydration to look out for.
The dull ache and throbbing pain in your temple could be the sign of more than stress in the office.
Amy said: "Of course the most obvious sign of dehydration in that situation is 'hangover' headaches."
Whether it's from having too much coffee instead of H20, there's no better way to combat a dehydration headache than with water.
Difficulty concentrating and increased fatigue
If staying focused is a struggle throughout the day, it could be due to lack of water consumption.
Amy said: "One of the primary signs of dehydration is poor concentration. This is because of the very high water content of the brain making it sensitive to dehydration.
"Fatigue and lowered immunity are (also) signals water are so vital in helping to flush acidic toxins from our bodies. If we do not neutralize the by-products of inappropriate and often excessive consumption of acid forming foods and drinks this will result in impaired immune response."
To stay properly hydrated, Amy advises eating plenty of fruit, an excellent source of water, among other helpful habits.
She said: "If you're concerned about what's in your tap water, or mindful of contributing to the environmental impact caused by disposable plastic water bottles, you can try a water filter.
"It transforms the water into alkaline antioxidant water which helps (it) be better absorbed into the body."
And in what may come as a surprise to some, the expert advises drinking room temperature beverages rather than cold.
Amy explained: "While cold drinks are absorbed quicker, warmer or room temperature drinks keep your body temperature optimal, which is ideal when exercising in the cold.
"Try to cut down on the caffeine too as this is dehydrating."
