Cold Weather Emergencies in Texas
While Texas is known for heat, cold weather emergencies are a real and often underestimated danger. Texas winters, particularly in the Panhandle, Hill Country, and North Texas, regularly bring freezing temperatures, ice storms, and occasional Arctic blasts that catch many ranchers unprepared. The 2021 Winter Storm Uri demonstrated how quickly cold can become deadly, with over 700 Texans losing their lives.
Ranch work doesn't stop for cold weather. Livestock still need feeding, water systems freeze and break, and animals may require emergency care during the worst conditions. Knowing how to recognize and respond to hypothermia and frostbite can save lives - including your own.

Understanding Hypothermia
What is Hypothermia?
Hypothermia occurs when the body loses heat faster than it can produce it, causing core body temperature to drop below 95°F (35°C). The body's normal temperature is 98.6°F (37°C). Even a small drop can impair brain function and muscle control, and severe hypothermia can stop the heart.
How Hypothermia Develops
- Conduction - Direct contact with cold surfaces (sitting on cold metal, wet ground)
- Convection - Wind carrying heat away from the body (wind chill effect)
- Evaporation - Wet skin or clothing accelerates heat loss dramatically
- Wind exposure while working
- Fatigue reducing the body's ability to generate heat
- Inadequate clothing for conditions
- Extended time outdoors
- Dehydration (reduces circulation)
- Alcohol consumption (dilates blood vessels, accelerates heat loss)
Stages of Hypothermia
#### Mild Hypothermia (90-95°F / 32-35°C)
- Cold, pale skin
- Numbness in extremities
- Difficulty with fine motor tasks (buttoning, using tools)
- Mild confusion or impaired judgment
- Increased urination
- Fatigue
- Increased confusion, disorientation
- Slurred speech
- Poor coordination, stumbling
- Drowsiness
- Slow, shallow breathing
- Weak pulse
- Making poor decisions (may try to remove clothing)
- Extreme confusion or unconsciousness
- Very slow or absent pulse
- Very slow or absent breathing
- Rigid muscles
- Dilated pupils
- May appear dead
Hypothermia Emergency Response Protocol
Step 1: Recognize the Emergency
- Person is showing any signs described above
- "The Umbles" - stumbles, mumbles, fumbles, grumbles
- The victim may deny feeling cold
- Confusion may be mistaken for fatigue, intoxication, or other causes
Step 2: Call for Help
- Exact location
- Estimated duration of cold exposure
- Current condition (conscious? breathing? shivering?)
- Environmental conditions
- Barn or building
- Any structure that blocks wind and wet
- Insulate from ground (hay, blankets, saddle pads - anything)
- Create a shelter using available materials
Step 4: Handle Gently
- Keep horizontal if possible
- Avoid jarring movements
- The cold heart is extremely irritable and can develop fatal arrhythmias with rough handling
- Allow them to walk or exert themselves
- Give them alcohol
Step 5: Remove Wet Clothing
- Replace with dry layers
- If dry clothing unavailable, remove wet clothing and insulate with any dry material available
Step 6: Rewarm Appropriately
#### For Mild Hypothermia (Shivering, Alert):
- Warm (not hot) drinks - NO alcohol or caffeine
- Warm environment
- Skin-to-skin contact (share body heat)
- Warm water bottles or chemical heat packs to trunk (armpits, chest, groin) - wrap in cloth to prevent burns
- Handle extremely gently
- Do NOT apply external heat sources to extremities
- Focus warmth on the core (trunk) only
- Warm, humidified oxygen if available
- Transport to medical facility ASAP
Step 7: Monitor Continuously
- Pulse (may be very slow and weak - check for 60 seconds)
- Level of consciousness
- Temperature if thermometer available
- Continue CPR until help arrives - "Nobody is dead until they're warm and dead"
- Cold patients have survived prolonged CPR that would be futile at normal temperatures
Frostbite Recognition and Response
What is Frostbite?
Frostbite is actual freezing of body tissue. Ice crystals form in and between cells, damaging tissue. It most commonly affects fingers, toes, nose, ears, cheeks, and chin - areas with less blood flow and more exposure.
Stages of Frostbite
#### Frostnip (Pre-Frostbite)
- Numbness or tingling
- Skin still soft when pressed
- No permanent damage if treated at this stage
- Soft tissue beneath still pliable
- Stinging, burning during rewarming
- Blisters may form (often clear fluid) after rewarming
- Medical evaluation recommended
- May heal completely with proper care
- No sensation
- May appear mottled, blue, or black
- Blisters may be blood-filled after rewarming
- Tissue death is likely
- May require surgery, possible amputation
- Do NOT rewarm if refreezing is possible - frozen tissue survives better than tissue that's been frozen, thawed, and refrozen
Frostbite Emergency Response
Step 1: Protect the Tissue
- Do NOT rub or massage the affected area
- Do NOT walk on frostbitten feet unless absolutely necessary
- Do NOT apply snow or ice
- Do NOT pop blisters
Step 2: Assess for Hypothermia
- Then address frostbite
Step 3: Determine Whether to Rewarm
- The tissue will NOT refreeze
- Evacuation to medical care is not possible for hours
- Medical care is available within 1-2 hours
- The person needs to use the frozen part to reach safety (walk on frozen feet)
Step 4: Rewarming Protocol (If Appropriate)
- The water should feel warm but NOT hot to an unaffected hand
- Immerse the frostbitten area completely
- Do NOT use direct heat (fire, heating pad, vehicle heater) - tissue can burn without feeling it
- Keep water at constant temperature - add warm water as it cools
- Continue for 20-30 minutes or until skin is red/pink and soft
- REWARMING IS PAINFUL - this is expected and actually a good sign
- Place sterile gauze between fingers/toes
- Elevate the affected area
- Cover loosely with sterile dressings
- Give ibuprofen for pain and to reduce inflammation
- Seek medical attention
Special Situations
Wet Cold vs. Dry Cold
- A soaked rancher in 40°F weather is at higher risk than a dry rancher in 20°F weather
- Falling through ice or into stock tanks is an extreme emergency
- Remove all wet clothing
- Aggressive rewarming needed
- Near-drowning may accompany hypothermia
- Consider CPR if unresponsive
Alcohol and Hypothermia
- Impairs shivering response
- Impairs judgment about seeking shelter
- Creates false sensation of warmth
- Seek shelter before confusion sets in
- Call for help while you still can
- Begin self-rewarming
Livestock Emergencies in Cold
- Breaking ice on stock tanks
- Rescuing animals from frozen ponds
- Extended time treating sick animals
- Take breaks to warm up
- Use buddy system
- Prepare warm shelter nearby

Prevention Strategies
Clothing System (Layering)
- Keep extra dry layers available
- Change out of wet clothing immediately
- Cover head (30-40% of heat loss from uncovered head)
- Protect extremities (gloves, warm socks, face covering)
Work Practices
- Take regular warming breaks
- Stay hydrated (dehydration reduces circulation)
- Eat regularly (calories fuel heat production)
- Avoid alcohol
- Work in pairs when possible
- Know the signs of hypothermia in others
- Don't push through "I'll just finish this task"
Environmental Awareness
|-------------|-----------|------------|----------------| | 20°F | 15 mph | 6°F | 30 minutes | | 20°F | 30 mph | -1°F | 10 minutes | | 0°F | 15 mph | -19°F | 10 minutes | | 0°F | 30 mph | -26°F | <10 minutes |

Bottom Line
- Hypothermia can occur above freezing - especially when wet, windy, or exhausted
- Shivering stopping is dangerous - means the body has exhausted warming ability
- Handle cold patients gently - rough movement can trigger fatal heart rhythms
- Core rewarming only for severe hypothermia - don't warm extremities first
- Nobody is dead until warm and dead - continue CPR until help arrives
- Frostbite: rewarm only if it won't refreeze - refreezing causes worse damage
- Rewarm frostbite in warm water - never with direct heat
- Wet cold is more dangerous - change wet clothing immediately
- No alcohol - it makes hypothermia worse, not better
- Prevention through proper clothing and awareness - layered, dry, and watching for signs
