What is what level of alt is dangerous?

A dangerous level of altitude, also known as high altitude sickness or acute mountain sickness, typically occurs at elevations above 8,000 feet (2,400 meters) above sea level. Symptoms can include headache, fatigue, dizziness, nausea, and shortness of breath. If left untreated, high altitude sickness can progress to more severe forms such as high altitude pulmonary edema (HAPE) and high altitude cerebral edema (HACE), which can be life-threatening.

It is important for individuals traveling to high altitudes to acclimatize slowly by allowing their bodies time to adjust to the decrease in oxygen levels. It is recommended to ascend no more than 1,000 feet (300 meters) per day above 10,000 feet (3,000 meters) and to take frequent breaks to rest and hydrate. If symptoms of high altitude sickness develop, it is important to descend to a lower altitude immediately to allow the body to recover.

It is also important to stay hydrated, avoid alcohol and tobacco, and eat a high-calorie diet to help prevent high altitude sickness. In severe cases, supplemental oxygen or medications may be necessary to treat high altitude sickness. It is important to be aware of the dangers of high altitude and to take appropriate precautions when traveling to high elevations.
