Dawn Johnson of San Antonio is a veteran insurance and financial services executive. A former member of the executive council of USAA, Dawn Johnson spends some of her free time scuba diving.

Scuba tanks are what hold divers’ air reserves while underwater, allowing them to swim with fish for extended periods of time. They are made from a variety of materials, including aluminum and steel. An average scuba tank holds a standard 80 cubic feet of air, compressed to 3,000 pounds per square inch. It can last a diver anywhere from 45 to 60 minutes at an average depth of 40 feet.

Contrary to popular belief, the tanks are not filled with pure oxygen. Rather, they contain a mixture of oxygen, nitrogen, argon, carbon dioxide, helium, and neon, which are prevalent in the Earth’s atmosphere. Nitrogen is the majority at 78 percent, oxygen comes in second at 21 percent, and the remainder is a mixture of other gases.

There are tanks with hybrid mixtures used by professional divers who intend on staying longer underwater or to compensate for the high pressure at depth. A good example is a nitrox cylinder, which has a higher concentration of oxygen, up to 40 percent, allowing more oxygen into the bloodstream.

Dawn Johnson, USAA former executive council member, has more than two decades’ worth of experience in insurance and financial services. A firm believer in giving back, Dawn Johnson has supported the Leukemia and Lymphoma Society.

Part of the Leukemia and Lymphoma Society’s mission is to improve the quality of life of patients diagnosed with leukemia or lymphoma by offering them free information and support. It recently published an article explaining why weight loss is a red flag for cancer patients.

Body weight is a measurement closely monitored by doctors in the course of cancer treatment. Changes in body weight offer insight into the side effects of cancer, the progress of your treatment plan, and your body’s continuing treatment needs. Unchecked weight loss can lead to treatment delays, decreased treatment progress, reduced germ resistance, and an overall lower quality of life. Strategies that can help you maintain a healthy weight during cancer treatment include:

1. Tackling nutrition problems directly. These problems may include difficulty swallowing, constipation, or dry mouth. Consult your medical team to quickly address these issues.

2. Fixing eating times. Eat small meals throughout the day in two- to three-hour intervals. Alternatively, you can carry a snack to eat when you are feeling hungry.

3. Consuming more calories. Add high calorie condiments such as vegetable oil, margarine, shredded cheese, mayonnaise, and cream to your food.

Drawing on background as a marketing executive at USAA, Dawn Johnson of San Antonio is the founder and CEO of DMJ Consulting, a firm focusing on assisting business executives in the strategic development of marketing plans. Apart from leading her firm, Dawn Johnson stays healthy by engaging in various forms of exercise.

In the warm-weather months, residents of Texas cities like San Antonio should adhere to the following safety tips when exercising in the hot weather:

1. Choose the right clothing: While cotton clothes may be more comfortable, consider investing in an exercise outfit made from a moisture-wicking material. Such a garment will help keep you cool by drawing sweat away from your body.

2. Change up your activities: Instead of choosing a run as your cardio exercise, consider opting for an activity that allows for a reduction in temperature. Biking, for instance, will allow wind to flow over your skin, and swimming can elevate your heart rate while the water temperature keeps you cool.

3. Take it easy: Rather than ramping up the intensity of your workout, maintaining a slow and steady level of physical activity is a better idea in the summer. Make sure to pay attention to how your body feels throughout a workout, remembering not to push yourself too hard in the hot weather.
