Read on to better understand hives.
What is urticaria?
Before going further, it is necessary to know how these red patches appear. Here are some explanations.
Definition
If you present red, blistered patches on the skin, you have hives. These seizures are often accompanied by itchy.
Seizures are due to the activation of mast cells (white blood cells). They react to allergens and cause an inflammatory reaction.
Most of the time, attacks of urticaria are benign and go away in less than 48 hours. However, some of them are more alarming. They portend other reactions in the body that can be much more serious, such as angioedema.
Different types
There are 2 types of hives.
- Acute urticaria: a single outbreak is observed, it lasts a few days at most. It is possible to develop this form several times in one’s life. Generally, the red patches appear in different places from previous times.
- Chronic urticaria: outbreaks are repeated regularly (every 2 to 3 days or even every day) over a period of at least 6 weeks. It is a chronic inflammatory disease. It can be accompanied by other symptoms: fevers, joint pain, stomach aches. It disappears following a few months or even a few years.
Urticaria episodes affect a large number of people. Often not serious, it is still necessary to consult in case of doubt.
What causes this rash?
Red, itchy patches can occur for many reasons.
The allergies
Your body may react to an allergy to:
In this case, the inflammation can be very virulent and angioedema may follow the crisis. An allergological assessment is strongly recommended once the crisis has passed.
Cold
It is enough to be exposed to the cold for a few minutes to notice a rash. The reactions are very varied from one individual to another.
In some people, the cold causes a drop in blood pressure. This can cause discomfort with loss of consciousness or even a state of shock.
The sun
After a few minutes in the sun, red or streaky spots appear on your skin. These are accompanied by itching. This means that you are having an allergy to the sun’s rays.
This case is quite rare. However, it can cause chronic hives.
Intense effort and stress
Here we are talking regarding cholinergic urticaria. Stress, the heat of a bath, intense effort increase body temperature. Most of the time, the red patches appear on the torso.
Infections
Viral infections like the common cold, covid, mononucleosis or hepatitis may cause rashes. UTIs and strep throat can also cause this type of rash.

How to relieve skin rashes?
Most of the time, the red patches and itching disappear within 48 hours. However, this period remains particularly unpleasant. Here are some remedies to relieve you.
Natural remedies
Hives can be itchy and feel hot. A bath in lukewarm water can relieve you. Be careful to use a neutral pH soap. You can add baking soda to your water. It has a very interesting anti-inflammatory action.
In addition, it is possible to calm the itching thanks to soothing essential oils. Lavender or peppermint essential oils are very effective, for example.
A few compresses of cold water or cider vinegar on the affected area relieves you. Finally, aloe vera is a plant with many virtues. Apply a little gel on the redness.
Medication
Creams and ointments are often ineffective. Often, antihistamines are offered in case of skin reaction. In effect, this limits the effects of the potential allergy.
Responding to hives: what to remember
Most attacks of hives are often mild. Use a few remedies to relieve yourself. The plaques and itching fade on their own.
However, it can also reveal a more serious allergy and cause a very virulent reaction that can go as far as asphyxiation. Follow the recommendations carefully in order to adopt the right behavior in the event of rashes.
