Is there any harm to the human body from ice cream patches? Are ice cream patches useful?

Ice cream patches are generally harmless to the human body and can relieve local fever or pain when used correctly. However, people with sensitive skin may experience allergic reactions. Ice cooling patches mainly function through physical cooling and are suitable for mild fever or cooling after exercise, but cannot replace medication for disease treatment.

The main ingredients of the ice cream patch are cool substances such as gel layer and menthol, which can take away heat on the body surface through water evaporation to achieve cooling. Normal skin use for 4-6 hours usually does not cause damage, and temporary whitening of the skin at the affected area is a normal phenomenon. When the product meets the national medical device standards, it will not contain harmful chemical components to the human body. The infant specific version will also reduce the concentration of menthol and reduce stimulation. Summer outdoor workers or athletes can use it to prevent heatstroke, and the auxiliary antipyretic effect is more significant when the fever is below 38.5 ℃.

Some people may have contact dermatitis after use, which is characterized by redness, swelling and itching of the application site, which is related to individual allergy to hydrogel or adhesive. The use of the damaged skin may delay the wound healing. Those with diabetes who are insensitive at the end need to prevent low-temperature burns. Continuous use for more than 8 hours may cause pore constriction disorders, and there is a risk of ingestion during nighttime sleep. Pregnant women are prohibited from using ice cold patches containing camphor ingredients, as the use of menthol containing products by epilepsy patients may trigger seizures. Applying ice cold patches to large blood vessels such as the carotid artery may cause blood pressure fluctuations, which heart disease patients should avoid.

When choosing ice cream patches, attention should be paid to checking the medical device registration certificate number to avoid purchasing three no products. Clean the skin before use and avoid mucous membrane areas such as the eyes, mouth, and nose. Apply for no more than 6 hours each time. When the antipyretic effect is not significant or the body temperature exceeds 38.5 ℃, medical attention should be sought in a timely manner. Do not rely on ice cream patches to treat diseases. Store in a cool place to prevent ingredients from evaporating, and use as soon as possible after opening to ensure cooling effect. If there is an allergic reaction on the skin, stop immediately and rinse with water. If the symptoms persist, seek medical treatment.
