Seeing as breathing is such a vital and fundamental part of our lives, one might think that we do it correctly, however we often don’t. We tend to take shallow breaths and hold our breaths when focusing or under pressure. This lowers our oxygen levels causing fatigue and a lack of clarity and we can make poor decisions and perform poorly as a result. Sitting still in an office chair can also create an oxygen deficit and it is the reason why after vegging-out in front of the TV we feel exhausted even though we haven’t done anything strenuous.
Oxygen thins the blood slightly which helps to lower your blood pressure and speed up the blood flow. This increases your metabolism and burns more calories, therefore the more oxygen you have in your blood, the faster your metabolism will be. You also burn more calories sitting outside than you do sat indoors, as cool air increases your metabolism as it tries to expend more energy keeping your body at a comfortable temperature. Therefore it is more beneficial to exercise outside than indoors.
If you’re unable to exercise then deep, active breathing for a couple of minutes a day can increase your oxygen intake, reduce stress, strengthen muscles and burn more calories.
Also oxygen helps to break down fat molecules and the blood then picks up the waste carbon dioxide to transport it out of the body via the lungs, therefore the more oxygen we take in, the more fat molecules that can be burned off.
‘Oxycise’ is the latest weight loss programme sweeping across America claiming to transform body shape, shed pounds, improve muscle tone and boost energy level based on the information above. Instead of doing high impact aerobic exercise, Oxycise breathing techniques can be done anywhere. The deep breathing forces us to use more of our lungs, to tighten and strengthen the diaphragm muscles which makes our muscles contract and combined with some gentle exercises can burn fat and tone up muscles. A study even found that a women burned 140% more calories than riding an exercise bike.
However sceptics say that breathing too deeply is harmful as it can ‘disturb the balance between carbon dioxide and oxygen needed to neutralise the blood and can cause light headiness and fainting’ and that deep breathing is not going to burn enough calories to transform body shape, it may burn up 2% fat at best, Prof McDonald states.
The jury’s still out without more detailed studies and research but it’s an idea to definitely think about as it is such an easy technique that we can all do.
