What cyclists must know about cold-related illnesses
Winter cycling can be just as enjoyable as riding in warmer weather—if you do it right. However, heading out unprepared can turn your ride into a nightmare! That’s why it's essential to understand the cold-weather health issues that cyclists commonly face and know how to prevent them.
### How the Cold Affects the Body
Exposure to cold weather impacts the body in multiple ways, increasing stress on your system. As temperatures drop, your body loses heat more quickly and triggers a defensive response. When this happens, your body works harder to maintain its functions, which is why winter rides feel so much more strenuous.
To protect itself, your body redirects blood flow away from your extremities and toward your core. This means your heart has to work harder, leading to an increased heart rate and blood pressure. Additionally, cold air can cause muscle contractions, making joints stiffer and muscles tighter. This not only makes movement more difficult but also increases the risk of injury and post-ride soreness.
Breathing in very cold air for long periods can also strain your respiratory system. While your nasal passages and airways usually warm the air before it reaches your lungs, prolonged exposure can still lead to discomfort, such as a runny nose or frequent urination.

### Common Cold Weather Biking Ailments
Riding in the cold can increase your chances of various injuries, including muscle strains, sprains, and even more severe conditions like hypothermia and frostbite.
#### Muscle Sprains, Strains, and Tears
Muscles are more vulnerable in colder temperatures, increasing the risk of injury. A **sprain** involves damage to ligaments, often due to twisting or overextending a joint. Symptoms include pain, swelling, bruising, and instability. A **strain** is a stretch or tear in a muscle or tendon, typically caused by overuse or sudden exertion. Signs may include pain, stiffness, weakness, and spasms. A **tear** is a more severe injury involving torn tissue, with symptoms like intense pain, swelling, and visible deformity.
**Prevention:** Always warm up before riding and avoid stopping unless necessary. Wear proper gear like knee warmers and choose lower gears. A good bike fit is also important.
**First Aid:** Rest the affected area immediately. For severe cases, seek medical attention. Use ice or heat and anti-inflammatory medication for milder symptoms.
#### Hypothermia
Hypothermia occurs when your body loses heat faster than it can produce it. Initial symptoms include shivering, fatigue, and confusion. In severe cases, there may be no shivering, blue skin, and loss of consciousness.
**Prevention:** Check the forecast and avoid riding in extreme cold. Dress appropriately and don’t ride if conditions are unsafe.
**First Aid:** Move to a warm place, remove wet clothing, and focus on warming the core. If someone has no pulse, start CPR immediately.
#### Frostbite
Frostbite is the freezing of body parts like fingers, toes, ears, and nose. It can cause permanent tissue damage and even require amputation in severe cases.
**Prevention:** Avoid prolonged exposure to cold without proper gear. Keep feet and hands dry and warm.
**First Aid:** Rewarm the affected area gently in warm (not hot) water. Do not rub or massage the area. Seek medical help if symptoms persist.
#### Immersion Foot (Trench Foot)
This condition results from prolonged exposure to cold, wet conditions. It doesn't involve freezing but can lead to tissue death and gangrene.
**Prevention:** Wear waterproof footwear and keep feet dry. Avoid tight shoes that restrict circulation.
**First Aid:** Dry and warm your feet. Avoid walking if possible. Seek medical attention if symptoms worsen.
#### Frostnip
A mild form of frostbite, frostnip causes numbness and discoloration of the skin. There is no permanent damage, but it should be treated by rewarming the affected area.
**Prevention:** Dress warmly and avoid prolonged exposure to cold.
**First Aid:** Rewarm gradually. No further treatment is usually needed.
#### Pernio (Chilblains)
Pernio is a reaction to repeated exposure to cold and damp conditions. It causes red, itchy, and painful patches on the skin.
**Prevention:** Keep skin warm and dry. Avoid riding in wet conditions if your gear isn’t suitable.
**First Aid:** Warm the skin slowly and use corticosteroid creams to reduce itching and swelling.
#### Bronchoconstriction
Cold air can cause the airways to narrow, making it harder to breathe. This is especially common in people with asthma or other respiratory conditions.
**Prevention:** Warm up properly before riding and avoid intense exercise if you have a respiratory infection.
**First Aid:** Stop riding and move to a warmer environment. Consult a doctor if symptoms persist.

### Be Prepared
Being prepared is the best way to ensure a safe and enjoyable winter ride. Dress appropriately, plan ahead, and take steps to stay warm. With the right gear and mindset, you can make the most of your winter cycling adventures.
#### Dress the Part
Layering is key when it comes to winter cycling. Your head and neck lose a lot of heat, so wear a beanie under your helmet and a balaclava or turtleneck for extra protection. Insulated gloves, thick socks, and waterproof boots are essential. Make sure your clothes are snug but not restrictive, and avoid wearing too many layers that could limit mobility.
#### Keep Your Body Warm
Warming up before your ride is crucial. Don’t stop unless necessary, and plan your route to include places to warm up if needed. Staying active helps maintain body heat.
#### Think Ahead
Check the weather forecast before heading out. Pack essentials like extra layers, tools, water, and snacks. Being prepared for the unexpected can save you from a bad day on the road.
