Ray Mears' Extreme Survival - Survival skills - Netflix
Survival skills are techniques that a person may use in order to sustain life in any type of natural environment or built environment. These techniques are meant to provide basic necessities for human life which include water, food, and shelter. The skills also support proper knowledge and interactions with animals and plants to promote the sustaining of life over a period of time. Survival skills are often associated with the need to survive in a disaster situation. Survival skills are often basic ideas and abilities that ancients invented and used themselves for thousands of years. Outdoor activities such as hiking, backpacking, horseback riding, fishing, and hunting all require basic wilderness survival skills, especially in handling emergency situations. Bush-craft and primitive living are most often self-implemented, but require many of the same skills.
Ray Mears' Extreme Survival - Water - Netflix
A human being can survive an average of three to five days without the intake of water. The issues presented by the need for water dictate that unnecessary water loss by perspiration be avoided in survival situations. The need for water increases with exercise. A typical person will lose minimally two to maximally four liters of water per day under ordinary conditions, and more in hot, dry, or cold weather. Four to six liters of water or other liquids are generally required each day in the wilderness to avoid dehydration and to keep the body functioning properly. The U.S. Army survival manual does not recommend drinking water only when thirsty, as this leads to underhydrating. Instead, water should be drunk at regular intervals. Other groups recommend rationing water through “water discipline”. A lack of water causes dehydration, which may result in lethargy, headaches, dizziness, confusion, and eventually death. Even mild dehydration reduces endurance and impairs concentration, which is dangerous in a survival situation where clear thinking is essential. Dark yellow or brown urine is a diagnostic indicator of dehydration. To avoid dehydration, a high priority is typically assigned to locating a supply of drinking water and making provision to render that water as safe as possible. Recent thinking is that boiling or commercial filters are significantly safer than use of chemicals, with the exception of chlorine dioxide.
