What causes your leg/foot to tingle and "fall asleep"?
Karen L. Gorton, PhD, MS, RN, Emergency Room Nursing, answered on behalf of Honor Society of Nursing (STTI)When your leg/foot tingle and "fall asleep", they are experiencing a decrease in oxygen. The tissues in our body need oxygen to live. Oxygen is delivered to the tissues via our blood. When the blood supply to the tissues is reduced, or cut off, the tissues begin to respond to the decreased oxygen levels. The tingling and falling asleep occur when the decreased oxygen levels occur.
Does the body adjust to altitude changes?
Discovery Health answered
Our bodies make adjustments at higher altitudes. They create more red blood cells to carry oxygen through our bloodstream, which pushes air into normally unused portions of the lungs and produces citrate synthase. Citrate synthase is an enzyme that helps the oxygen found in hemoglobin to make its way into body tissue.
High altitude also triggers an increase in our breathing, heartbeat and urination. Low air pressure and low humidity at high altitudes cause moisture from your lungs and skin to evaporate more quickly, and your body's increased exertion requires more water to remain hydrated.
How does donating blood affect the body?
If you are fit and healthy you should not experience any problems after donating blood. However, you may feel slightly sluggish or tired but that will go away as your body replenishes it's fluids. Be sure to eat regular meals and drink plenty of fluids before and after donating blood.
