Did you know that you can exercise the muscles you use to breathe? A new gadget called an inspiratory muscle-strength training device, originally invented to help people with respiratory diseases including asthma and COPD, can help. To use it, plug your nose, hold it up to your mouth and inhale. The device provides resistance, forcing you to work hard to breathe in. A University of Colorado, Boulder, study concluded that doing 30 of these inhalations each day can reduce blood pressure. In fact, the average results were comparable to what people can achieve with medications or daily half-hour walks. If you opt for this strategy, choose a device that offers up to 100 cmH2O, a suitably high amount of resistance. You may be able to buy one over the counter, depending on where you live.
