“Alone” is a reality television show that airs on the History channel. It follows a group of contestants who are dropped off in remote wilderness locations with limited supplies and are required to survive alone for as long as possible. The show has gained popularity for its portrayal of the contestants’ struggles to find food, water, and shelter in harsh environments.

One of the concerns of the show is the health and safety of the contestants. As such, they undergo regular medical checks throughout their time on the show. The exact frequency of these medical checks is not specified, but it is known that the contestants are checked at least once a week. These checks are performed by the show’s medical team, which includes a physician, a nurse practitioner, and an EMT.
During these medical checks, the contestants are examined for any signs of injury or illness. They are checked for weight loss, dehydration, and signs of malnutrition. If any health issues are identified, the medical team will provide treatment or recommend that the contestant be removed from the show.
In addition to regular medical checks, the contestants are also required to wear a satellite phone at all times, which they can use to call for help in case of an emergency. The medical team is on call 24/7 and can be reached by the contestants at any time.
The safety of the contestants is taken very seriously on the show. The producers have stated that they have a duty of care to ensure the health and well-being of the participants. As such, the medical checks are an important part of the show’s safety protocols, and they are taken very seriously.
