Heat stroke is a serious medical condition that can be fatal if not treated promptly. It occurs when the body is unable to regulate its temperature, resulting in a core body temperature of 104°F or higher. Babies and young children are particularly vulnerable to heat stroke because they have a less developed ability to self-regulate their body temperature and a smaller body surface area to cool down through sweating. Additionally, they may not be able to communicate their discomfort or ask for shade or water. Certain factors, such as medications, weight, and other health conditions, can further increase the risk of heat stroke in children. It is important for caregivers to be vigilant in monitoring for signs of heat exhaustion and heat stroke, as early detection and intervention are crucial for preventing serious health complications or death.

What You'll Learn
Babies' inability to sweat
Babies are less able to sweat when hot. This is because a baby's body is immature and still learning to regulate its own temperature. Overheating in babies can be dangerous as they are less able to regulate their body temperature than adults.
Babies can't tell you if they are feeling hot, so it's important to monitor them during hot weather. If a baby is overdressed or over-bundled, they can get hot and uncomfortable, but they can't do anything to fix the problem. Their skin can't breathe, and they will be unable to cool down through sweating.
Babies who get too hot may be at risk of heat-related illnesses, such as heat stroke, which can be life-threatening. Signs of heat stroke include a high fever, flushed skin, confusion, coma, or shock. Babies with heat stroke will also often not sweat.
To prevent overheating, it is important to dress babies in cool layers and try to keep them in a cool environment. If a baby is sweating, it is a sign that they are too hot, and you should remove a layer of clothing or move them to a cooler area.
If a baby is showing signs of heat-related illness, it is important to begin cooling them down immediately by getting them out of the heat, removing their clothes, and using a fan or cool water. If a baby is showing serious signs of heat-related illness, seek emergency medical help.

Dehydration
Babies and young children are more susceptible to heat-related illnesses, including heat stroke, because they cannot sweat as effectively as adults. Sweating is the body's way of cooling down, and babies and young children are less able to sweat when hot. This means that they can develop heat-related illnesses much faster than adults.
Signs of dehydration in infants and young children include:
- Fewer than four wet diapers in 24 hours for infants (0-1 year)
- Fewer than three wet diapers in 24 hours for children (1-5 years)
- Peeing little, and fewer than four times a day for children not in diapers
- Heavy sweating followed by no sweating at all, with hot, dry, and flushed skin
- Seeming more fussy than normal
- No tears when crying
- Dry mouth and tongue
- Shallow breathing (especially in infants)
- A sunken soft spot on the head (if 18 months or younger)
If you suspect that a baby or young child is dehydrated, it is important to contact a healthcare provider right away. Steps you can take include giving the child lots of breast milk or formula if they are under one year old, and giving older children fluid replacement products such as diluted apple juice (half water, half apple juice).

Sensitive skin
Infants and young children have more sensitive skin than adults, which makes them more susceptible to sunburns. Sunburns can increase the likelihood and severity of heat-related illnesses, such as heat stroke.
Children's sensitive skin is more vulnerable to sun damage because it has less surface area to dissipate heat. Their skin has less space to sweat, and their temperature regulation capacity is not yet fully developed. This means that younger children tend to get heat exhaustion more quickly.
Additionally, children's sensitive skin can burn more easily when exposed to direct sunlight. This is because their skin is thinner and has not yet developed a strong protective barrier. As a result, UV rays can penetrate more deeply and cause more damage.
To protect children's sensitive skin from sunburns, it is important to take precautions such as seeking shade, using sunscreen, and wearing light, breathable clothing that covers their skin. It is also important to limit their time in direct sunlight, especially during the hottest parts of the day, and to ensure they stay hydrated.
By taking these precautions, you can help protect children's sensitive skin from sun damage and reduce their risk of developing heat-related illnesses, including heat stroke.

Inability to recognise distress
Recognising heat stroke in babies can be challenging as they cannot verbally communicate their discomfort. Here are some signs and symptoms to watch out for:
Babies may exhibit unusual behaviours or concerning symptoms when experiencing heat stroke. As babies cannot regulate their body temperature as effectively as older children or adults, it is crucial to monitor them closely during hot weather. They may become sleepy and difficult to wake up, or exhibit signs of lethargy and weakness. You may also notice movement and coordination problems, such as stumbling or appearing fussy.
One of the critical signs of heat stroke is hot, flushed skin. However, in some cases, the skin may feel cool and clammy despite the hot weather. This can be a result of dehydration, which is a significant risk factor for heat stroke. Dehydration can cause a baby to stop sweating, making it harder for their body to cool down.
Another indication of heat stroke is a high body temperature. A temperature above 39°C (102°F) is considered a symptom of severe heat-related illness, while a temperature above 38°C (100°F) indicates a mild to moderate heat-related illness. Take immediate action to cool down your baby and seek medical attention if their temperature rises above these levels.
Vomiting and diarrhoea are additional symptoms of heat stroke in babies. These can further contribute to dehydration, making it even more challenging for the baby's body to regulate its temperature. If you notice any signs of dehydration, such as a dry mouth and tongue or a decrease in wet diapers, it is important to encourage fluid intake and seek medical advice.
It is important to remember that babies may not exhibit all the typical signs of heat stroke, and they may just appear unwell or more irritable than usual. Trust your instincts, and if you suspect your baby is unwell, take steps to cool them down and seek professional advice.

Inability to self-regulate temperature
Babies and young children are at a higher risk of heat-related illnesses, including heat stroke, due to their inability to self-regulate their body temperature. This is because their bodies have a harder time self-regulating internal temperature or recognising that they are in distress. Their ability to regulate their internal temperature is not yet fully developed, and they have less body surface area to utilise to regulate their temperatures.
With less skin space to sweat, younger children tend to get heat exhaustion quickly. Babies cannot sweat, and more than 50% of children with heat stroke do not sweat, which means that they can develop heat-related illnesses much faster than adults. A child's body temperature rises three to five times faster than an adult's, and they also lose heat more slowly due to a less developed sweating mechanism and lower blood volume.
Additionally, toddlers and babies are unable to correct their body temperature independently. They are also unable to ask for water or shade as much as they need to. This makes it especially important to monitor them during periods of extreme heat.

Heat stroke is a life-threatening medical emergency. If you suspect your baby has heat stroke, call 911 immediately. While waiting for emergency services to arrive, move your baby to a cool area, elevate their feet, wet their skin or clothes, remove articles of clothing, and fan them vigorously. If they are conscious, give them cool water to drink.
To prevent heat stroke, ensure your baby is appropriately clothed in light, breathable clothing. Encourage them to play in shaded areas and offer water frequently. Avoid strenuous physical activity during the heat of the day and do not leave your baby unattended in a vehicle.
