The scorching summer sun can cause a heat stroke even in a healthy person. The heat just seems to suck away all your energy, making you feel weak and lethargic. Extreme dehydration can occur, and this heat stroke can easily progress into an illness that lasts longer than required. If you or anybody you know suffers from a heat stroke, use the remedies mentioned in this article for quick relief.

A heat stroke is also called sunstroke and is quite common during the summer months. It is important to understand the cause of this and also know how to identify the signs and symptoms. This way you can choose the right remedy for its treatment.

Hence, before delving into the home treatment solutions for a heat stroke, let’s examine the causes and symptoms.

What Causes Heat Stroke?

The fluids in our body are responsible for maintaining the body’s temperature during the hot weather conditions. The body sweats to release the excess heat and cool down when it is exposed to heat for a longer duration. When the body loses sufficient fluids (hydration), we experience dehydration and heat stroke. This heat exhaustion can easily progress to a life-threatening condition wherein the body temperature can rise up to 105 degrees Fahrenheit and cause neurological damage. A heat stroke can happen due to two reasons-

  • Exertion of the body in hot weather conditions, for example, playing a sport in the heat for many hours
  • Older people, children, and people with illnesses usually have trouble regulating their body temperature. They may suffer heat stroke on exposure to high temperatures, even without any physical activity (1, 2).

Heat stroke can be tackled easily by paying attention to the following symptoms.

Signs Symptoms Of Heat Stroke

Few warning signs indicate the onset of a heat stroke. These are as given below:

  • High body temperature (104 degrees Fahrenheit and above)
  • Nausea and vomiting
  • Headache
  • Dizziness and weakness
  • Flushed skin
  • Rapid breathing and increased heart rate
  • Muscle cramps and abdominal cramps
  • Lack of sweat or sweating heavily

Heat stroke starts after these warning signs appear and the symptoms of this are usually neurological. The patient may experience:

  • Irritability
  • Delusions and hallucinations
  • Bizarre behavioral changes
  • Seizures

A heat stroke can even progress to coma. Hence, these signs and symptoms should not be ignored and should be dealt with as soon as possible. Here are the best remedies that you can use to treat heat stroke and alleviate the signs and symptoms.
