When is flu season? Flu season varies from year to year – it can start as early as August and last into late spring.
What is the best way to prevent contracting the flu? For those who are eligible to receive it, vaccination is the number one prevention method. For those are not eligible to receive the vaccine – infants under 6 months old or those with certain allergies and medical conditions – it’s important for the other people in their household to get vaccinated.
What are the most common [...]
1. Hydrate for performance. When you are well-hydrated you perform better. Drink 2-3 cups of fluid two hours before you plan to workout and 1-2 cups about 30 minutes before. Being well-hydrated will help you feel more energized and alert.

2. Hydrate to prevent injury. Lack of fluid can leave you feeling tired, dizzy and clumsy, making you more likely to stumble and hurt yourself. Plan to drink eight gulps of fluid about every 15 minutes during a hard workout, especially if you are outdoors.
3. Choose the right drink at the right [...]
Ten years ago as part of standard preseason cognitive testing, a famous pro athlete tried to recite from memory the dozen words I had just read aloud.
At first, he gave me only four of the words. After two more repetitions, he got up to five.

I did not feel that he was giving me his best effort, so I told him he was performing like a patient who had either a severe head injury or was in the early stages of Alzheimer’s disease. “Sorry, doc,” he said. “That’s all I’ve got.”
He was [...]

2. Mix up your workouts to include both cardiovascular and muscle training exercises for a whole body fitness improvement plan. Cardiovascular exercise helps keep your heart healthy while muscle training exercise can improve posture and strength.
3. Try interval training to improve cardiovascular fitness and burn up calories. Interval training requires you to alternate bouts of high intensity with lower intensity during your workout.
4. Lift heavy enough to make a difference to build muscle. When strength training, the weight should be heavy enough to [...]
The West Nile Virus is a seasonal illness transmitted to humans through infected mosquitoes that flares up between May and October. UT Southwestern infectious disease experts Jeffrey Kahn, MD, PhD, and James Luby, MD, discuss the disease that affects as many as 1,000 people across the country each year.
1. Who is most at risk to contract and become ill from West Nile Virus?Dr. Luby: Everyone can become infected, but elderly persons and those with a compromised immune system have an extra risk of becoming ill after being bitten by an infected mosquito.
2. Is [...]
Newest labeling could help stem sun’s skin damage
Buying a sunscreen that really offers protection against skin cancer was supposed to get easier this summer. Instead, it could get even more confusing for consumers looking to protect their skin from the sun’s damaging rays.
Gabriela M. Blanco, MD
New guidelines from the Food and Drug Administration to simplify over-the-counter sunscreen labeling were expected to go into effect in June. A six-month delay, however, means that not all product lines will be following the adjusted rules. Still, informed consumers should keep an eye out for sunscreens that [...]

During the first month of my intern year in residency, I met a young female college student who had to leave school due to her ongoing battle with ulcerative colitis. She was hospitalized for two weeks to control her symptoms and required aggressive immunosuppressive therapy. I witnessed, firsthand, how diseases like ulcerative colitis and Crohn’s can affect someone’s physical wellbeing but can also change people’s lives—especially the lives of young women! I became interested in these diseases as a result. Over the years, thankfully, there has been increasing [...]
My medical education has supplied more than its share of medical terminology mouthfuls, but I had to tackle this troublesome tongue-twister during an altogether different occasion. I am a singer and have been privileged to record for Walt Disney Records over the years. As that famous song from Mary Poppins proves, the lyrics are sometimes as difficult to master as the tune.
As a recently appointed Assistant Professor of Laryngology in the Department of Otolaryngology-Head & Neck Surgery, it is thrilling for me to combine my musical interests with my passion for medicine [...]
