Treatment And Remedies For Rigors

It is advised not to ignore this type of a condition as it is often a marker for significant and sometimes serious infections, most likely being bacteria.

Therefore, it is important to recognize rigor in the individual as the episode is unlikely to be experienced by the person affected and, at the same time, to be aware of the possible significance of its symptoms.

We can treat it through medical treatment or can reduce it from home remedies. It all depends on whether your symptoms are several or mild.

A) Treatment For Rigors

The proper diagnosis for rigors in individuals depending on the clinical assessment and the likely causes.

Very often, the examination may reveal a source of infection, and treatment can be carried out without the need for further extensive diagnosis.

However, in children, extreme care should be taken, which includes seeking a professional doctor to treat the condition.

There is a couple of important diagnoses that are carried out in order to understand the condition properly.

These include:

  • Blood test
  • Urine test
  • CT Scan
  • MRI scan

Upon carefully running the diagnosis, the doctor usually carries out temperature-lowering general measures, particularly in children.

Other than this, the doctor may also prescribe medicines in order to reduce the temperature of the body.

B) Home Remedies For Rigors

If the rigors are for a short time with no fever at all then there are also some important remedies that can be performed at home in order to get relief from the rigors.

Following are some prevention tips and remedies that can provide you comfort and calmness if you are experiencing rigor:

1. Stay Hydrated

This is helpful in preventing a lack of fluid in the body which is known as dehydration. It might be useful to give paracetamol to the sufferer and then try again with drinking in half an hour and so on.

2. Don’t Sponge While Shivering

It is not recommended because if the water is cold, the blood vessels under the skin can become narrower and can further raise the temperature.

According to a study, people with rigors become uncomfortable while sponging during the shivering phase. You can do it with warm water but depending on the condition of the sufferer.

3. Don’t Over-Wrap Children

Children who have high-temperature should not be under-dressed and/or over-wrapped because this can worsen the situation by increasing the temperature furthermore.

4. Glucose Tablet

This is useful for diabetic patients. Take a glucose tablet if you have diabetes and the cause of your chill is hypoglycemia. Drinking orange juice, regular soda, eating a few pieces of candy can also help in balancing your sugar level.

5. Herbal Tea

It is a health provider of vitamins and minerals to the body. It is also a great home remedy to take whenever you experience sudden chills because it can take care of fluctuating body temperature.

6. Chicken Soup

It is a great remedy to fight for people who are suffering from rigors because it provides hydration to the body and it also contains nutritious ingredients. These ingredients are also easy to digest.

However, if after trying all the above remedies, you are still not getting comfort than you should definitely concern a doctor as soon as possible.


Rigors that occur without fever can be treated at home and also with changing of lifestyle like a workout routine.

If it occurs with a fever then you might need some medical treatment to cure it.  Talk to your doctor if you frequently experience sudden rigors or chills.
