Altitude & Sun

Boulder is 5,430 feet or 1,655 meters above sea level. For some, the high altitude can cause mild  for all, it means increased exposure to UV rays.

Tips:

  • Drink lots of water.
  • Wear sunblock, sunglasses, a hat and UV protected clothing.
  • Low humidity means that your skin will feel dry and may become irritated. If dry, apply moisturizer to your skin and use lip balm for dry lips.
  • Avoid excessive physical activity and give your body time to adjust to the altitude. Start by taking short walks.

Rocky Mountain Winters

Winter can be a difficult season if you come from a warm climate. Here are a few tips to stay safe and healthy during winter.

  • Drink lots of water.
  • Check the day’s temperature before going outside. A blue sky can look warm, but the air can still be very cold; wind is common.
  • On cold days, dress in layers.
  • Wear boots that have grip or add traction devices to shoes to prevent slipping on ice.
  • Avoid ‘cabin fever,’ the feeling of being stuck in one place for a long period of time. Tips include:
    • Study or do homework in a different location other than your room.
    • Meet up for board game nights or cook a meal with friends.
    • Talk to family on the phone or through video chat.
    • Exercise or go for a walk.
    • Attend a concert or visit an art gallery.
    • If you are feeling lonely, consider the Let’s Talk drop in session at The Rec or visit with Counseling and Psychiatric Services.
