Sponsored Post: Whether it’s freezing cold or scorching summer heat – extreme temperatures can be tough on horses too. To keep your horse healthy all year round, thermoregulation plays a key role. In this article, you’ll learn how horses regulate their body temperature, when they need extra support – and which rugs truly protect them from the cold.

How does your horse protect itself through thermoregulation in cold and heat – and when does it need your help?
Horses are true masters of adaptation: their individual comfort temperature – depending on breed, age, and housing – ranges roughly between -7 °C (dry cold) and +25 °C. But even with this wide range, extreme temperatures can become stressful, leading to reduced performance, discomfort, diarrhea, colic, or in severe cases, heatstroke or frostbite.
What many underestimate: horses regulate their body temperature through their skin, coat, blood vessels, and sweat glands. A thick winter coat, the layer of fat under the skin, and natural oil production provide protection – as long as we don’t disrupt this balance through improper management or equipment.
Key basics of thermoregulation in horses:
How horses generate and release heat
The difference between summer and winter coats
The influence of age, breed, health, and living conditions
Why the wrong rug in rainy weather can do more harm than good
Remember: A sweaty horse under a rug cools down faster than a wet horse without one – moisture trapped against the skin is dangerous.
How do horses regulate their body temperature?
Horses regulate their body temperature through a combination of skin, coat, sweat glands, and blood vessels – but under extreme temperatures, wet conditions, or improper management, this natural thermoregulation can reach its limits.

When does a horse need a rug? – Essential rug guidelines
Whether and when a horse should be rugged depends on several factors – not just the temperature. Important aspects include breed, age, health, housing (outdoor vs. stall), training level, and coat condition.
In general:
Untrained or clipped horses usually need a rug sooner than hardy horses with a full winter coat.
Strong wind, continuous rain, or high humidity greatly increase the chilling effect – in such cases, a rain sheet can be useful even around freezing temperatures.
In severe frost (-5 °C and below), a winter rug may be necessary, especially for clipped or older horses.
Typical temperature guidelines (approximate):
| Outdoor temperature | Recommendation for clipped horses | Recommendation for unclipped horses |
|---|---|---|
| +10 °C to +5 °C | Transitional or lightly lined rug | Usually no blanket needed |
| +5 °C to 0 °C | Lined rug | Possibly a rain sheet if wet |
| 0 °C to -5 °C | 100–200 g filling | Winter blanket only if necessary |
| -5 °C and below | 200–300 g filling | Blanket older horses if needed |
Important: A winter rug provides insulation against the cold, while a rain sheet mainly protects against wet and chilly weather – it’s usually unlined but waterproof and breathable.
Well wrapped for winter – with the right rug, your horse stays protected from cold and wet weather.

Rugging, changing, and removing – how to adjust your horse’s rug to the weather
The weather changes – and with it often comes the question: Rug on or off? Especially during the transition periods between autumn and winter or in early spring, sensitivity is key. Incorrect rugging can disrupt your horse’s natural thermoregulation – leading to overheating, sweating, or in the worst case, chilling.
Important everyday tips:
Check the weather daily: Pay attention not only to temperature but also to wind, rain, and humidity – they greatly increase the cooling effect.
Regular touch test: If your horse feels warm and dry behind the withers, everything is fine. If it feels hot and damp, overheating may be imminent. If it feels cold, your horse might already be freezing.
Don’t forget to change rugs: When temperatures rise or fall, switching rugs can make sense – for example, a lighter one in the morning and a warmer one in the evening.
Gradually remove rugs in spring: To prevent the winter coat from shedding too early, reduce rug use step by step as temperatures become consistently warmer.
To avoid interfering too much with your horse’s thermoregulation, always choose rugs based on both weather conditions and your horse’s individual type – one-size-fits-all solutions rarely work.
What happens inside a horse’s body during overheating or hypothermia?
It’s not just freezing cold that can stress a horse’s body – extreme heat can be just as dangerous. On hot summer days, horses reach their limits quickly: they overheat up to ten times faster than humans. When temperatures exceed 35 °C, intensive training or transport should be avoided whenever possible. If a horse must still be exercised or transported – for example, in an emergency – it’s essential to provide proper cooling: shade, airflow, and cool (not cold) water help stabilise circulation.
Horses with dark coats heat up more quickly because they absorb more sunlight. Similarly, northern breeds like Icelandic or Fjord horses are generally more sensitive to heat than hardy warmbloods or Iberian horses accustomed to warmer climates.
However, cooling also requires care: while cold water is beneficial, it should never be applied abruptly or in large, icy amounts. Otherwise, circulatory issues, muscle tension, or even shock may occur. Sensitive areas such as the kidney and loin regions should always be cooled carefully.
Cold weather poses its own challenges: when exposed to low temperatures, blood vessels constrict; as the body warms up again, they dilate. This natural mechanism can even be used therapeutically to stimulate circulation and help flush out inflammatory substances.
What are the symptoms of disrupted thermoregulation?
When a horse’s thermoregulation is impaired, symptoms vary depending on the cause. In cold conditions, signs include muscle trembling, low body temperature, and stiffness. In hot conditions, horses may show excessive sweating, rapid breathing, and signs of overheating.
What warning signs does your horse show in heat or cold?
Here’s an overview of the most important signs to watch out for:
| Condition | Typical signs |
|---|---|
| Overheating | – Rapid breathing, flared nostrils – Lethargy – Pale or dark mucous membranes – Elevated body temperature – Heavy sweating, dehydration – Stumbling or uncoordinated movement (ataxia) – Circulatory failure or collapse |
| Freezing | – Muscle trembling – Tense muscles, tucked tail – Stiff gait – Raised coat – Displeased or tense expression – Low body temperature |
Normal body temperature in horses
Does your horse feel hot – or rather cool? A thermometer gives you reliable clues. But what’s considered normal, and when does it become dangerous? Here’s a quick guide:
| Temperature | Classification |
|---|---|
| 32.0 – 37.2 °C | Hypothermia |
| 37.3 – 38.2 °C | Normal temperature |
| 38.3 – 39.5 °C | Mild fever |
| 39.5 – 40.5 °C | Fever |
| 40.5 – 42.0 °C | High fever |
| 39.0 – 39.5 °C | Typical after exercise (can reach up to 40 °C with intense effort). Combined with high ambient temperatures, this can quickly become dangerous for the circulatory system. |
What is the comfort temperature for horses?
The comfort temperature for horses ranges roughly between -7 °C (in dry cold) and +25 °C, depending on the horse’s breed, age, health condition, and housing.
How to blanket your clipped or actively trained horse in winter
Sport horses or horses that are in regular winter training are often clipped to prevent excessive sweating and to help them dry off more quickly after exercise. However, once the coat is clipped, the horse loses an essential part of its natural thermoregulation – it can no longer retain warmth effectively and becomes far more sensitive to cold, wind, and moisture.
What’s especially important:
Start rugging early, once temperatures drop below around 10 °C, depending on the type of clip and weather conditions.
Keep multiple blankets on hand for different situations – e.g. a cooler, a lightweight transitional rug, a padded winter rug, or a rain sheet. Tip: All new turnout rugs in the Winter Collection are now liner compatible. This means you’ll need fewer rugs overall – just adjust the inner layer depending on the weather. It saves space in your tack room, money in your wallet, and makes washing much easier.
Remove the blanket before training to avoid overheating – and always use a cooler afterward to help the horse dry safely.
Provide proper insulation at night, especially for horses kept outdoors or in stables with fluctuating temperatures.
Important: For clipped horses, regularly check that the blanket still fits well, sits correctly, and meets your horse’s current warmth needs. Too much protection can be just as harmful as too little.
