Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it has not been clear how. "Our research shows that within seconds, at low levels of oxygen (hypoxia), a protein called small ubiquitin-like modifier (SUMO) is linked...
Open windows or get outside to breathe fresh air.Something as simple as opening your windows or going for a short walk increases the amount of oxygen that your body brings in, which increases overall blood oxygen level. It also has benefits like improved digestion and more energy. Quit smokin...

Get some fresh air: Move to an area with better ventilation or step outside for fresh air, which can help you quickly replenish your oxygen level. 10 Ways To Improve Your Blood Oxygen Levels Over Time The best way to increase oxygen levels in the blood will depend on what the cause is...
In the early 1990s,SemenzaandRatcliffeindependently discovered that cells adapt to changes in oxygen levels by making more of a protein calledhypoxia-inducible factor-1or HIF-1. When oxygen levels decrease, the HIF protein inhibits oxygen-consuming processes of the cells by altering the activity of...
How to Reduce Gift Wrap Waste Wrapping paper may have “paper” in its name, but that doesn’t automatically mean it can be recycled.1Try these suggestions for cutting down the amount of wrapping paper you throw away. Reuse what you have.2It’s estimated that the U.S. produces 4.6 mill...
The concentration of the alcohol in the alveolar air is related to the concentration of the alcohol in the blood. As the alcohol in the alveolar air is exhaled, it can be detected by the breath alcohol testing device. Instead of having to draw a driver's blood to test his alcohol level...
Before we get to the how, it’s important to understand the why. Simply put, your blood oxygen level is the amount of oxygen circulating in your bloodstream. Most of the body’s oxygen is carried within our red blood cells. These cells gather oxygen from the lungs where we breathe it ...
from your daily activity and calorie burn to ongoing heart rate, sleep, and more. There’s one additional useful feature when it comes to heart health that you can get with the Apple Watch: you can take an ECG (electrocardiogram) test to check for irregularities in your heart rhythm, other...
Three scientists who studied how cells sense and adapt to oxygen levels have been awarded the Nobel Prize in Physiology or Medicine. William G. Kaelin, Jr. of the Dana-Farber Cancer Institute and Harvard University, Sir Peter J. Ratcliffe of Oxford University and the Francis Crick Institute, ...
