Take her body temperature and apply a cold ice bag on the injured body areas. Have Monica drink lots of water to stay hydrated. Yogurt is a fabulous medicine for sunburned skin, but an aloe vera body cream is even better. Rub it all over the burned areas, continuing the first aid with a burn relief spray and syrup. Monica is out of danger and she does not need to be rushed to hospital. She will use a protective sun tanning lotion next time she goes to the beach, as well as a big sun hat and sunglasses.
