Your complexion can reveal a lot more about your health than simply whether you are dehydrated or have spent too much time in the sun. In fact, how your skin looks can be a strong indication of whether you’re making the best food choices for your body. That’s because food allergies and intolerances can compromise the digestive and immune systems, giving rise to acne, eczema, rosacea, and other bothersome skin conditions.
Higher facial temperatures may be linked to the skin disorder rosacea, according to Dr. Mark Dahl of the Mayo Clinic in Scottsdale, Ariz. Characterized by facial bumps and acne, a swollen nose, redness over the nose and cheeks, and small dilated blood vessels in the skin known as telangiectasia, rosacea may be caused by changes in temperature, affecting the toxicity of bacteria in the face. At higher temperatures, an enzyme called lipase is released more readily than at lower temperatures, causing a depletion of nutrients and, thus, dryness in the face.
