You might think ringworm only appears during hot, humid months. However, you can still catch it in winter. Dry air often makes your skin crack, and you likely spend more time indoors. Shared spaces like gyms and locker rooms increase your risk. In fact, winter accounts for nearly a third of all cases, as shown in the chart below.

Simple habits can help you stay protected. Ringworm Seasonality does not end when summer does, so you should stay aware and take action.
What Is Ringworm?
Ringworm is one of the most common fungal skin infections you can get. Doctors also call it tinea. This infection affects your skin, hair, or nails. You may notice a ring-shaped, itchy, red rash if you have it. Three main types of fungi cause ringworm:
Trichophyton
Microsporum
Epidermophyton
These fungi live on your skin and can survive on surfaces for a long time.
Symptoms
You might see different symptoms depending on where ringworm appears on your body. The table below shows the main types and their signs:
Type of Ringworm |
Symptoms |
---|---|
Body Ringworm |
- Red, ring-like rash with raised edges. |
Scalp Ringworm |
- Red, scaly rash on the scalp. |
Athlete's Foot |
- Whitening of the skin between the toes. |
Jock Itch |
- Red, ring-like patches in the groin area. |
Tip: If you notice a red, itchy rash that looks like a ring, you should check with a doctor. Early treatment can stop the infection from spreading.
How It Spreads
Ringworm spreads easily, especially in winter when you spend more time indoors. You can catch it in several ways:
Touching the skin of someone who has ringworm
Petting or grooming animals with the infection
Using objects or touching surfaces that have the fungus, such as towels, gym mats, or hairbrushes
You can lower your risk by washing your hands often and not sharing personal items.
Ringworm Seasonality in Winter

Why It Happens
You may think ringworm only grows in warm, humid weather. In reality, ringworm seasonality affects you all year. The fungus that causes ringworm survives on skin and surfaces, even when temperatures drop. During winter, you spend more time indoors. This creates close contact with others and increases your risk. Dry air makes your skin crack, which gives fungi more places to enter. You touch shared items like towels, gym mats, and clothing more often. These habits help ringworm spread.
Ringworm seasonality does not stop in cold months. Scientific studies show that ringworm cases remain high in winter. One study found that the prevalence of ringworm in calves reached 54% in winter. The risk was lower than in summer, but still much higher than in spring or autumn. You can see that ringworm seasonality continues, even when the weather turns cold.
Note: Fungi that cause ringworm can survive on surfaces for weeks. You should clean shared spaces often to lower your risk.
Common Winter Triggers
Winter brings new triggers for ringworm seasonality. You face different risks compared to summer. Here are some common triggers:
Dry, cracked skin: Cold air and indoor heating dry out your skin. Cracks make it easier for fungi to infect you.
Shared indoor spaces: You spend more time in gyms, locker rooms, and schools. These places have many surfaces that carry fungi.
Damp clothing: Wet socks, gloves, and hats stay on your skin longer. Moisture helps fungi grow.
Close contact: You gather with family and friends indoors. This increases skin-to-skin contact and the chance of spreading ringworm.
Winter Trigger |
How It Increases Risk |
---|---|
Dry skin |
Cracks allow fungi to enter easily |
Shared spaces |
More surfaces for fungi to survive |
Damp clothing |
Moisture helps fungi multiply |
Close contact |
Spreads infection between people |
Ringworm seasonality means you must stay alert in every season. You can protect yourself by knowing these triggers and changing your habits. Simple steps help you avoid infection, even when winter brings new risks.
Winter Risk Factors
Damp Clothing
You face a higher risk of ringworm when you wear damp clothing in cold weather. Wet socks, gloves, or hats can trap moisture against your skin. This creates a perfect environment for fungi to grow. Your body works harder to stay warm when your clothes are wet, which can weaken your immune system. Microbes and fungi thrive in damp conditions and can enter your skin through small cuts or cracks.
Damp clothing promotes the growth of fungi, including ringworm.
Wet clothes create a favorable environment for microbes to multiply.
Microbes can penetrate your skin through openings, leading to infections.
Wearing wet clothing in cold weather can weaken your immune system.
Increased dampness raises your risk of infections and illnesses.
Tip: Change out of wet clothes as soon as possible. Dry your skin thoroughly before putting on fresh clothing.
Shared Indoor Spaces
You spend more time indoors during winter, often in places like gyms, locker rooms, and schools. These shared spaces can become breeding grounds for fungal infections. Sweat and direct contact with surfaces help fungi spread quickly. Warm and moist conditions inside these environments allow ringworm to thrive.
Shared indoor spaces like gyms encourage fungal infections due to sweat and contact.
Warm, moist conditions help fungi grow, including ringworm.
Practicing good hygiene is essential to prevent ringworm in these places.
Shared spaces during winter increase your risk of fungal infections.
Showering after workouts reduces your risk of skin infections.
Prolonged contact with sweaty clothes encourages fungal growth, especially in shared facilities.
Note: Always use your own towel and avoid sharing personal items in public spaces.
Dry, Cracked Skin
Cold air and indoor heating can dry out your skin. When your skin becomes cracked, its natural barrier weakens. This makes it easier for fungi like ringworm to infect you. Irritated skin increases your risk because fungi can enter through small breaks. You should keep your skin moisturized to help protect against infection.
Keeping your skin healthy and hydrated lowers your chance of getting ringworm during winter.
Prevention Tips for Winter

Keep Skin Dry
You can lower your risk of ringworm by keeping your skin dry. Fungi love moist, warm places. After you shower or exercise, dry off completely. Use a towel or let your skin air dry. If you sweat during winter activities, change out of wet clothes as soon as possible. Showering after sports helps wash away sweat and reduces moisture on your skin. You can also use a cool hair dryer to help dry hard-to-reach areas, like between your toes.
Tip: Always dry between your fingers and toes. These spots often stay damp and can become a home for fungi.
Change Clothes Promptly
Damp clothing creates the perfect environment for ringworm. You should change out of wet socks, gloves, or hats right away. Do not wait until you feel cold or uncomfortable. Wash your undergarments after every use. For other clothes, like jeans or sweaters, wash them after every three wears, or sooner if they get sweaty or damp. Quick changes and clean clothes help keep fungi away from your skin.
Change out of damp clothes immediately after use.
Wash undergarments after each wear.
Wash other clothing items after three uses, or sooner if damp.
Practice Good Hygiene
Good hygiene protects you from ringworm. Wash your hands often, especially after touching shared surfaces or animals. Keep your nails short and clean. Clip them regularly to prevent fungi from hiding underneath. Shower after sports or gym sessions. Always use your own towel and personal care items.
Wash hands with soap and water.
Clip and clean your nails.
Shower after physical activities.
Use your own towel and toiletries.
Avoid Sharing Items
You can stop ringworm from spreading by not sharing personal items. Do not share towels, hats, hairbrushes, or clothing. In gyms or locker rooms, use sandals or shower shoes instead of going barefoot. Clean gym equipment before and after you use it. Disinfect surfaces at home and in shared spaces. If you have pets, check them for signs of ringworm and avoid contact if they show symptoms.
Note: Keeping your environment clean and not sharing items are simple ways to protect yourself and others from ringworm during winter.
If You Notice Symptoms
Early Signs
You should watch for early signs of ringworm, especially during winter. Fungal infections often start with small changes on your skin. Look for these signs:
Red or pink patches on light-colored skin
Brown or gray patches on skin of color
Slow-growing patches that can appear on various body areas
Center of patches may clear first
Intense itching
Fungal infections may look different on each person. You might see patches on your arms, legs, scalp, or even your feet. The itching can become very strong. If you notice these changes, you should act quickly. Early action helps stop fungal infections from spreading to others.
Home Care
You can manage mild fungal infections at home. Start by keeping the affected area clean and dry. Try these home care tips:
Use aloe vera gel directly on the affected area to soothe symptoms.
Apply oregano oil mixed with a carrier oil to help fight fungal infections.
Use lemongrass oil for its antifungal properties by mixing it with a carrier oil.
Consider over-the-counter antifungal treatments containing clotrimazole or terbinafine.
Wash your hands after touching the rash. Change your clothes and bedding often. These steps help prevent fungal infections from spreading in your home. If you have pets, check them for signs of fungal infections as well.
Tip: Always finish the full course of any antifungal cream, even if the rash looks better. Stopping early can let fungal infections return.
When to See a Doctor
You should see a doctor if home care does not help. If the rash gets worse, spreads quickly, or covers a large area, seek medical advice. Fungal infections on the scalp, face, or nails often need prescription medicine. If you have a fever, pain, or pus, call your doctor right away. Some fungal infections can look like other skin problems, so a doctor can give you the right diagnosis.
Doctors can prescribe stronger treatments for stubborn fungal infections. Early treatment keeps you healthy and protects others from getting sick.
You can protect yourself from ringworm this winter by following a few simple steps. Keep your skin clean and dry. Wear sandals in public locker rooms. Change into clean socks and underwear every day. Avoid sharing personal items like towels or bedding. Moisturize your skin often, especially after washing. Use plain soap and avoid very hot water. If you notice symptoms, act quickly. Staying alert and caring for your skin helps you stay healthy all year. 😊
