Explain if the statement is true or false.

“It becomes difficult to breathe when we go to higher altitudes.”

The given statement is TRUE.

As we go to higher altitudes, the air pressure decreases, and the amount of oxygen in the air also decreases. This decrease in oxygen availability makes it difficult for our lungs to take in enough oxygen, leading to shortness of breath and difficulty breathing. This is commonly known as altitude sickness or acute mountain sickness. 

It is more common at altitudes above 8,000 feet (2,400 meters) and can cause symptoms such as headache, nausea, dizziness, fatigue, and difficulty sleeping. It is important to acclimate gradually to higher altitudes to allow the body to adjust to the lower oxygen levels.
