Red Flags For Your Skin: Know What Those Red Itchy Spots & Blotches Are Saying

When you get a skin rash, the affected skin becomes red, inflamed and bumpy. Some skin rashes are dry and itchy; some are painful. These red spots or itchy bumps on the skin have various possible causes. The most common are:

• Viruses
• Bacteria
• Overheating
• Allergens
• Skin conditions such as eczema

Itching is a common symptom of all these problems, and other symptoms of rashes often overlap. Many rashes are red, painful, itchy, and bumpy. While most rashes go away fairly quickly and independently, others are long-lasting and require long-term care. Some conditions may even require immediate medical attention. Certain rashes or red, itchy bumps can also lead to blisters or patches of raw skin that can be extremely painful to touch.

Sleepless and Itchy: Bumps, Scratches, and Midnight Mysteries

Perpetually itchy skin at night, also called pruritus or nocturnal itching, occurs when you get itching and the urge to scratch your skin, especially at night. This can disturb your sleep and compromise your overall health.

Itchy bumps or rashes on the skin at night may occur due to changes in body temperature, dry skin, or as a symptom of an underlying disease. There are many reasons your skin may itch at night, and if the problem is constant, it's essential to find out the reasons behind it so you can get the proper support and treatment.

A) Factors Causing Nocturnal Itching

The causes are not fully understood, but some factors play a role.

1. Body Heat

At night, our body's temperature naturally drops 0.5-1℃ to promote better sleep. To release the heat, our skin's temperature rises, and blood flow to the skin increases, which can contribute to nighttime itching and create more rashes and red itchy bumps.

2. Dryness

The increased blood flow and higher temperature increase the skin's permeability. This means that water and moisture are lost more quickly, resulting in skin dryness at night. The dryness may lead to itchy bumps.

3. Inflammation

Inflammation can also contribute to nocturnal itchy bumps. Some cells release cytokines at night, which are small proteins that activate the immune system. Some cytokines cause inflammation, which can cause itching. The body produces less corticosteroids at night, which control inflammation. This may lead to more red, itchy bumps. You can try anti-inflammatory foods for the skin such as turmeric, walnuts, berries to prevent skin inflammation. 

B) Health Conditions Causing Nocturnal Itching

Your rashes and red, itchy bumps associated with certain medical conditions may be worse when you're trying to sleep. Let us see the common reasons for nocturnal itching:

1. Skin Conditions

Common skin conditions like psoriasis, eczema and dry skin may be the culprit behind your itchy bumps, rashes and red spots, which could be worse at night.

2. Old Age

Older people are more prone to red, itchy bumps and rashes at night, partly because their skin tends to dry out with age.

3. Mental Health Problems

Excessive anxiety and stress release the body's cortisol and adrenaline at night, which can contribute to red, itchy skin.

4. Infestations

Bedbugs, lice and scabies cause itching, especially at night. Bed bugs feast on blood while you're in bed, and their bites can cause rashes. Similarly, scabies are caused by tiny mites that burrow into your skin and cause rashes and itchy bumps. 

Rash Attack: The Causes of Itchy Bumps & Blotches On Skin 

Itchy bumps and red (sometimes raw) patches on the skin can be caused by a number of factors, including: 

1. Skin Conditions

• Eczema: A skin condition which is chronic and inflammatory. It causes dry, red patches and itchy bumps on the skin. 
• Psoriasis: A condition that causes raised, itchy bumps and red, scaly patches on one's skin. It is an autoimmune disease.
• Contact dermatitis: Allergic or irritant reaction to certain substances. It results in red, itchy bumps and rashes.
• Pityriasis Rosea: An inflammatory skin condition that first appears as a large patch, usually on the chest, back, or abdomen. 
   

2. Infections 

• Bacterial infection: Conditions such as folliculitis or impetigo can result in red, pus-filled bumps on the skin. 
• Viral infections: Chicken pox or measles can cause red spots or rashes. 
• Fungal infections: Conditions such as ringworm or candidiasis can cause itchy bumps and scaly, small, red patches on the skin. 
   

3. Insect Bites or Stings

A mosquito, flea or bee sting can cause red, swollen and itchy bumps on the skin.

Keep the area clean and avoid scratching the bite to prevent infection. If the itching affects your sleep, your pharmacist can help with antihistamines and mild steroid creams.

4. Menopause

Menopause can make your skin itchy because estrogen is essential for healthy skin, and estrogen levels drop during menopause. When hormone levels drop, your skin can feel thin and dry and break out with itchy bumps and rashes.

5. Pregnancy

Itching is common during pregnancy due to increased blood flow to the skin. However, it can also mean a more severe disease called intrahepatic cholestasis of pregnancy (ICP).

Symptoms of ICP include itching without a rash, often on the hands and feet. It can be worse at night. Other symptoms include dark urine, pale stool, and signs of jaundice, such as yellow eyes.

6. Hives And Allergic Rashes

Hives are patches of raised, red, itchy bumps on the skin that can cover a large area or just one part of the body. An allergic rash can have itchy bumps, blisters, and rough and scaly skin.

Hives and allergic rashes are caused by the release of high levels of histamine, such as an allergic reaction or eating certain foods. Treatment includes over-the-counter antihistamines.

7. Allergy

Airborne or food allergies, medications, or environmental allergens can cause red, itchy bumps or rashes. 

8. Burning Heat

Excessive sweating during exercise or in hot or humid weather can clog skin pores, resulting in small, itchy bumps and red spots, especially in areas where the skin rubs together, such as the armpits or between the thighs.

9. Psychogenic Itch

Chronic itching without an apparent underlying cause could be a symptom of obsessive-compulsive disorders, delusional parasitosis, somatoform disorder or depression. Consult a psychiatrist for proper diagnosis and treatment.

10. Iron Deficiency Anaemia

People with iron deficiency anaemia may have itchy bumps on their skin. Other symptoms include fatigue, pale skin, shortness of breath, and a fast heart rate. Take iron-rich foods or supplements like Spirulina Powder. 

11. Chronic Idiopathic Pruritus

When an itch lasts longer than six weeks without a particular cause, it is called chronic idiopathic pruritus. It can be challenging because it can significantly impair a person's quality of life.

Treatment Options For Itchy Rash All Over Body: Tackling Those Red Spots 

The perfect treatment for itchy bumps and skin rashes depends on the cause. The rash or itch may disappear on its own or may take several weeks of proper care. Treatment for skin rashes and itchy bumps includes:

1. Anti-Inflammatory Creams

Nonprescription corticosteroid creams may offer short-term relief of itchy bumps and inflamed skin.

2. Allergy Medications

Oral antihistamines are a type of allergy medication that reduces itchy bumps and rashes.

3. Immunosuppressants

If the rash is caused by eczema or an immune system reaction, different medications can reduce the reaction, reducing the inflammation and itching.

4. Steroids

If your symptoms persist, your dermatologist may prescribe an oral or topical steroid cream, which can help stubborn itchy bumps and rashes.

5. Topical Immunomodulators

These drugs change (modulate) your body's immune system's response to allergens. Prescription medications include tacrolimus ointment and pimecrolimus skin cream.

6. Alternative Treatment

If your itching won't let you sleep, you can try melatonin. This natural hormone helps regulate sleep. When taken in the evening, it has a soothing effect that can help you sleep through the itching.
