Most people look forward to hot summer days when they can soak in the sun and enjoy a variety of activities outdoors. But for many rosacea sufferers, summer fun can trigger unsightly flare-ups that inevitably put a chill on the season. Here are some precautions you can take:

• Sun exposure is the most common rosacea tripwire, so wear sunscreen with an SPF (sun protection factor) of 15 or higher every day -- even when it is overcast. If sunscreen irritates your skin, try a pediatric formulation.

• Avoid direct sunlight whenever possible while outdoors. Wear a brimmed hat to shield your face, and opt for shady areas.

• Protect your face on windy days with a light scarf and large-brimmed hat.

• Avoid high-intensity workouts in the heat and sun. Try low-intensity exercise routines at shorter but more frequent intervals, preferably in early morning or evening when temperatures are lower.

• Chew on ice chips; cool your face with a spray bottle filled with water; or drape a cold, wet towel around your neck to avoid flushing and overheating from hot weather or physical exertion.
