Dry Desert Air & Your Child’s Skin and Airways This Winter

Why Las Vegas Winters Are Uniquely Challenging for Kids

When most people think of winter health concerns, they picture snow and freezing rain. Here in Las Vegas, our winter challenge is different: extremely low humidity. During February, relative humidity in the Las Vegas valley can dip well below 20 percent — far lower than the 30–50 percent range that the Environmental Protection Agency considers comfortable for indoor environments. For children, whose skin is thinner and whose airways are still developing, this persistent dryness can contribute to a range of uncomfortable symptoms.

Understanding how dry air affects young bodies — and knowing what steps may help — can make a meaningful difference in your child’s comfort and well-being throughout the season.

How Dry Air May Affect Your Child’s Skin

According to the American Academy of Pediatrics (AAP), a child’s skin is more susceptible to moisture loss than adult skin. When the surrounding air lacks humidity, the outermost layer of skin can lose water more quickly, potentially leading to:

• Dryness and flaking — especially on the cheeks, hands, and legs
• Itching and irritation — which may disrupt sleep and daily comfort
• Worsening of existing skin sensitivities — dry conditions can aggravate skin that is already prone to irritation

Infants and toddlers may be especially vulnerable because they have a higher surface-area-to-body-weight ratio, meaning they can lose moisture through the skin more rapidly. School-age children and adolescents who spend time outdoors for sports or recess may also experience chapping on exposed areas of the face and hands.

How Dry Air May Affect Your Child’s Airways

The National Institutes of Health (NIH) note that adequate moisture in the airways plays an important role in the body’s natural defense mechanisms. The mucous membranes lining the nose and throat help trap particles and pathogens, but they function best when properly hydrated. In dry desert air, these membranes can become dry and less effective, which may:

• Contribute to nosebleeds, which are common in children during dry winter months
• Lead to a scratchy or sore throat, especially upon waking
• Increase nasal congestion and discomfort

The AAP notes that younger children, particularly those under age five, may be more affected because their nasal passages are narrower and can become obstructed more easily when mucous membranes are irritated.

Practical Tips to Help Protect Your Child

Supporting Healthy Skin

• Moisturize after bathing. The AAP recommends applying a fragrance-free, hypoallergenic moisturizer within a few minutes of bath time, while the skin is still slightly damp. This can help lock in hydration.
• Keep baths lukewarm and brief. Hot water may strip natural oils from the skin. Aim for baths of 10 minutes or less.
• Dress in soft, breathable fabrics. Layering with cotton or other gentle materials can reduce skin irritation, especially for infants and toddlers.
• Protect exposed skin outdoors. Las Vegas winter days can be sunny and breezy. A gentle, broad-spectrum sunscreen on exposed areas and lip balm can help protect against wind and UV exposure — even in February.

Supporting Comfortable Airways

• Consider using a cool-mist humidifier. The AAP suggests that a cool-mist humidifier in your child’s bedroom may help add moisture to indoor air. Be sure to clean the unit regularly according to manufacturer instructions to prevent mold and bacterial growth.
• Encourage adequate hydration. Offering water throughout the day can support overall hydration. For infants under six months who are exclusively breastfed or formula-fed, additional water is generally not recommended — consult your pediatrician for age-appropriate guidance.
• Use saline nasal drops or spray. According to the AAP, saline drops can help keep nasal passages moist and may provide relief from dryness-related congestion. This approach is generally considered safe for children of all ages.
• Monitor indoor humidity. A simple hygrometer can help you keep indoor humidity between 30 and 50 percent — enough to support comfort without encouraging dust mites or mold growth.

Age-Specific Considerations

• Newborns and infants: Avoid lotions with fragrances, dyes, or alcohol. The AAP recommends ointment-based moisturizers for very young skin, as they tend to retain moisture more effectively.
• Toddlers and preschoolers: Encourage gentle nose-blowing techniques and keep fingernails trimmed to reduce scratching of dry, itchy skin.
• School-age children and adolescents: Remind them to drink water during school and after physical activity. Reapply moisturizer and lip balm as needed throughout the day.

When to Seek Professional Guidance

While dry skin and minor nasal dryness are common during a Las Vegas winter, certain signs may warrant a conversation with your pediatrician. These can include persistent skin cracking or bleeding, frequent or prolonged nosebleeds, difficulty breathing through the nose that does not improve with basic humidity measures, or skin irritation that interferes with sleep or daily activities.
