Upper UTIs are infections of the kidneys. These are potentially life threatening, if bacteria move from the infected kidney into the blood. This condition is called sepsis. Sepsis can cause dangerously low blood pressures, shock, and death.
So whe you hold your breath, you stop getting oxygen in your lungs that go to your heart. The oxygen level in the blood drops, so your muscles need more oxygen, so the heart pumps faster. This is like running, your muscles need more oxygen so heart pumps faster
It is VERY dangerous to hold your breath for long periods of time. The human body can only last about 2 minutes without oxygen before making your lungs breathe in more. When y â¦ ou hold your breath, your heart uses the oxygen you used in your last breath. Once it's done, it needs more right away.
