With the changing weather, it is common to experience skin redness and itching owing to the rising temperatures and the summer heat. Most of them subside within a few days and do not cause pain. However, in some cases, the problem can become severe flare-up can occur. There can be multiple causes of these red spots on the skin. In this article, we have compiled the 10 most commonly occurring skin problems in 2023 which result in the appearance of red spots and patches.

  1. Heat rash

The most common cause of red spots on the skin is sweat production which clogs the skin’s pores. This trapped sweat within the skin gives rise to small blisters which turn into painful and itchy lumps. Areas more prone to be affected by a heat rash are the ones where the skin tissues get rubbed against each other e. g. armpits or the clothes rub with the skin e.g. near the neck. Using a calamine lotion or an anti-rash powder can help with this type of rash.
