Cardiovascular problems
Cardiovascular problems may have many causes and are as likely to occur in the mountains as they are in an urban environment. In particular, a state of exhaustion brought on by physical exertion can give rise to cardiovascular problems. The circulatory system can be adversely affected, for example, if you don’t eat or drink enough or fail to take adequate rest stops.
Typical symptoms for cardiovascular problems include a drop in physical performance, dizziness, nausea, unsteadiness walking, shock symptoms such as paleness and a cold sweat, and even temporary loss of consciousness.
A person suffering from cardiovascular problems should take a rest, drink fluids and lie with their legs in a raised position. On warmer days, a cold compress wrapped around the calves may help. You can do this by soaking a T-shirt in water and wrapping it around the calves.
Generally, the body will soon recover. If after a short time the person shows little sign of recovery, and the intake of food and drink has brought about no improvement, an emergency call will be necessary.
If the person remains unconscious but breathing, they should be placed in the stable recovery position; if they are not breathing, you should begin resuscitation.
