Three ways to protect oneself from the sun is;
1. Wearing sunscreen protection
2. Wearing sunglasses, long sleeves, and a hat
3. Getting outdoors before 10 am and after 4 pm when the sun rays are least strong
When sun rays hit the skin, a cascade of biochemical pathways is significant in the uptake of vitamin D from the gut. Vitamin D is important in the absorption of calcium and minerals into bone and making them strong. This prevents diseases such as rickets.
When you feel the need to sneeze, the best step to follow would be to put the crease in your mid-arm up to your nose and sneeze into that. This will prevent germs from spreading to others if you sneeze into the air or your hand.
Depending on what your answer options are, it is either perspiration (sweat) or sweat glands.
