11 Reasons Why You Have Red Dots On Your Skin
Heat Rash: Hot and humid weather can cause your sweat glands to clog, leading to tiny red bumps or dots on your skin. They often appear on areas like the back, chest, and neck.
Allergic Reactions
Exposure to allergens from food, medicine, or environmental factors can trigger red spots. These might itch or swell and often disappear after removing the allergen.
Petechiae
Tiny red dots that appear when small blood vessels under the skin break. Petechiae don’t fade when you press them and could indicate infections or blood disorders.
Keratosis Pilaris
Commonly called “chicken skin,” this condition causes small, rough red bumps, especially on the arms, thighs, and cheeks, due to clogged hair follicles.
Contact Dermatitis
Skin irritation caused by touching chemicals, soaps, plants, or metals. It leads to itchy red patches or dots that can blister if not treated.
Insect Bites
Mosquitoes, bedbugs, or fleas often leave behind red, itchy dots that can sometimes swell. Scratching them may worsen the irritation.
Cherry Angiomas
Small, harmless growths of blood vessels that appear bright red on the skin. They usually increase with age and are typically not a cause for concern.
Fungal Infections
Conditions like ringworm can create red, circular dots or patches on the skin. They often spread if untreated and usually itch a lot.
Eczema
A chronic condition that can cause red, inflamed, and sometimes dry patches. Stress, allergens, and weather changes often trigger flare-ups.
Psoriasis
This autoimmune disorder leads to the rapid buildup of skin cells, forming scaly, red patches that may itch or burn. It’s a lifelong condition with manageable symptoms.
Viral Infections
Certain viruses like chickenpox, measles, or hand-foot-and-mouth disease cause widespread red dots. These conditions often come with fever and other symptoms.
Conclusion
Red dots on your skin can range from harmless to signals of deeper health issues. If they persist, spread, or are accompanied by other symptoms, consulting a healthcare provider is a smart move.
