Summer days: can your skin take the heat?
Whether you’re on holiday or staying at home, summer heat can seriously deplete your body’s mineral levels, leading to skin feeling tighter and more sensitive.
We asked dermatologist Dr. Nina Roos for her tips on surviving the city’s summer heat, while taking care of our skin.
How does heat affect the body’s mineral levels?
Alongside vitamins, minerals help fulfil key functions for metabolism and the skin's structure and its functions, helping skin to remain healthy. With perspiration, our body’s mineral salts evaporate and need replenishment. In total, the human body loses between 1,600ml and 1,800ml of fluid each day due to perspiration, including minerals such as sodium, iron, and phosphate ions, all of which are essential to healthy skin, bones and teeth. In addition to the negative effects of dehydration, the sun’s UV rays also encourage the development of free radicals, which can contribute to premature aging by speeding up cell breakdown.*Research suggests that a significant amount of skin degradation, including cancer is linked to the exposome, particularly pollutants, UV rays and ozone. ** Studies have also shown that extended exposure to heat can contribute to a breakdown in skin elasticity.

Rehydrating skin in summer: how mineralizing water can help
So, how best to keep the body’s mineral levels in check when it’s hot outside? To help strengthen from the inside out, spritz a mineral-rich water fortified with all the elements your skin needs across your face and body as soon as you begin to feel dehydrated. Dermatologist Dr. Nina Roos says: “A facial mist rich in diverse mineral elements will help to calm and soothe skin irritated by summer heat. It’s important to choose a gentle, hydrating product that won’t stress out delicate skin.”
Certain elements are known for their beneficial effects on skin. Sulphur and silicon promote collagen production and help with wound healing, while magnesium and lithium promote cell repair - ideal for when you’ve spent too long in the sun! Drinking enough water and making sure your diet contains enough trace minerals (minerals not naturally produced by the body) will have your skin looking as good on the outside as it feels on the inside. The better hydrated your skin, the more your body will feel the benefits of the vitamins and minerals it needs.
