Summarize the following:
Individuals with psoriasis are often very sensitive to weather conditions. Cold and dry conditions can exacerbate psoriasis, while warmer and more humid environments may ease and prevent uncomfortable flare ups. Checking the environmental conditions at your destination can help you better prepare for your trip, including knowing what types of supplies, medications, and clothing to bring. Look at the environmental conditions such as the temperature, relative humidity, and sun index for the time of year you plan to travel. Organizations such as the Environmental Protection Agency and local county extensions can give you information on these conditions. No matter where you’re traveling, having the proper gear can help minimize your risk of flare ups or worsening psoriasis. Once you’ve checked the environmental conditions, pack clothing and other gear that is appropriate for your destination.  Bring small bottles to carry a small amount of lotion, water, or another necessities during day trips. Pack cotton clothing if you can as it is less likely to irritate your skin or cause overheating. Loose clothing can also minimize rubbing that can irritate psoriasis. Consider specific conditions when packing clothing. For destinations with warmer and more humid aid, choose light and airy fabrics such as cotton and even viscose. Dresses and loose pants and shirts are excellent options. For cooler and drier temperatures, consider leggings or wider-legged jeans with shirts and natural fabric sweaters you can layer. Stressful travel conditions can trigger flare ups. Ask friends, family, or travel agents about the infrastructure at your destination. This can minimize stress or other factors that trigger flare ups.  Visit a local travel agent and ask for information on your destination. Even if you didn’t book your travel through them, they may be able to help you navigate public transportation or side trips with minimal cost. Understanding local infrastructure can ease stress and prevent flare ups. Ask friends or family members if they or someone they know have been to your destination. These individuals often have great tips from their travels. Check the web for local information. For example, if you want to go to Berlin, you can easily access local transport maps at http://www.bvg.de/en/. For someplace like India, you can find information at sites such as or http://www.goatsontheroad.com/backpackers-guide-transportation-in-india/. There is no special psoriasis diet, but some foods may make symptoms worse. Getting a sense of the cuisine at your destination may help you avoid foods that can worsen symptoms or cause flare ups. Going to restaurants in your area that serve the cuisine may give you an idea of what you can expect when you are abroad and help you figure out dishes you can safely eat. You can also look up recipes for common dishes and check the ingredients. Be aware that the following can make psoriasis symptoms worse:  Gluten Alcohol Red meat Dairy products Nightshade plants such as peppers, white potatoes, eggplant and tomatoes Citrus fruits such as grapefruit, oranges, lemons, and limes

Check the environmental conditions at your destination. Select items to pack based on the conditions. Ask about local infrastructure. Try the cuisine ahead of time.
