As winter brings colder temperatures and shorter days, many people in the UK experience dry skin, irritated scalps, and dull hair. While central heating and low humidity are well known contributors, experts say water quality is another factor that is often overlooked.

Hydration plays a central role in overall wellbeing, supporting mood, memory, skin health, and sleep quality. Dehydration and poor water quality have been linked to fatigue, dry skin, reduced concentration, and longer term risks such as urinary tract infections and kidney strain.

Alexander Provins, general manager at Tappwater and an expert in water filtration, says a broader approach to hydration is particularly important during winter. He emphasises the value of clean, filtered water for both internal hydration and daily washing routines.

Protecting the skin barrier

Tap water in many parts of the UK contains chlorine and limescale, which can strip the skin and scalp of natural oils. This may lead to dryness, irritation, and increased sensitivity, particularly during colder months.

Shower filters such as the Tappwater ShowerPro Rain showerhead and ShowerPro Diamond filter are designed to remove these impurities while helping the skin retain moisture. According to the company, regular use can support balanced skin pH, reduce acne, and limit oxidative stress linked to premature ageing. Users also frequently report softer hair and calmer skin after continued use.

Encouraging better hydration habits

Drinking enough water remains essential for brain function, energy levels, skin and hair condition, and kidney health. However, average water consumption in the UK remains low.

• The average Brit drinks 726ml of water per day.
• Women consume an average of 675ml daily.
• 7% of people report drinking no water at all.

NHS guidance recommends a daily intake of 1.5–2.5 litres. At the same time, 42% of the UK population say they distrust tap water, most commonly due to taste. Filtered water, which many describe as fresher and cleaner, may help encourage more consistent intake at home, at work, and when travelling.

Managing dry indoor environments

Winter heating can significantly reduce indoor humidity, leading to dry throats, chapped lips, and irritated eyes on waking. Low humidity also affects the skin and respiratory system by accelerating moisture loss.

Experts recommend maintaining balanced indoor humidity through humidifiers or smart heating controls. Improving air moisture levels can reduce irritation and support the body’s ability to retain hydration during prolonged periods indoors.

By addressing both water quality and indoor conditions, individuals may be able to reduce the effects of winter dehydration. Measures such as filtering shower water, drinking adequate amounts, and managing indoor humidity are associated with noticeable improvements in skin, hair, and general comfort.
