The sun is officially set in Alaska, and it won't be coming up for a while. Here are some tips that can keep you healthy if you're not seeing the sun for long stretches: 1. Make sure to still get outside and get some rays, even if it's not directly bright from the sun. 2. Take vitamin D supplementation. 3. Go to sleep at regular intervals. 4. Get a light therapy box to keep next to your bed or at your desk
