Your extreme fatigue might be coming from hidden sources. Nixing these spirit-depleting factors from your life will automatically help reboot your verve.
It turns out that even moderate dehydration (which results in the loss of 3 percent of your body weight) can make you feel mentally sluggish and mess with your concentration. The next time you're feeling foggy or lightheaded, don't just assume you're in serious need of some food. Try downing a glass or two of water.
2. Cell Phones
Checking your cell before bed amps up brain activity, making it harder to doze off. Plus, any electronic gadget's artificial blue light can suppress the sleep hormone melatonin. A 2011 poll by the National Sleep Foundation found that 20 percent of people ages 19 to 29 are awakened by a call, text, or e-mail at least a few nights a week. Power it down well before bedtime.
Many drugs have veiled energy-sapping side effects. Chief among them are some classes of antidepressants and certain beta-blockers used to prevent migraines or treat high blood pressure. If you start a new med and feel more lethargic than usual, see doctor Bert for an alternative. (If there isn't one, take your dose right before bed.)
While working out zaps the stress hormone cortisol, prolonged sweat sessions--like, for example, regularly running for more than 30 minutes at a steady rate--can actually rev cortisol production. Interval training (bursts of intense activity) combined with strength training (free-weight and body-weight moves) helps keep cortisol in check.
5. Low Iron
The mineral shuttles oxygen around your body and removes waste from your cells. If you're not getting around 18 milligrams a day, your body struggles to function properly and you can feel worn out; low iron levels in your diet can cause iron deficiency anemia. If you feel sluggish, call our office and ask for a simple blood test to see if you should be taking a supplement.

| Stroke volume is not about improving your golf score. At least, not directly. :-)
Physiologically, stroke volume is the amount of blood your heart pumps every time it beats. The more blood pumped per heartbeat, the less times your heart has to contract to provide the needed amount of blood.
Our heart's efficiency is directly related to stroke volume. Increased stroke volume means less work for the heart.
As you do more and better aerobic exercise, you are training your heart to be more efficient. Stroke volume increases over time as a result of this exercise, and you notice a number of things. First, it's much easier to walk up hills and other inclines. Stairclimbing requires no extra effort. If you're a swimmer, you can go longer between breaths and you can stay underwater longer.
And, you notice your heart rate goes down. A good resting pulse is 60 beats or less per minute. Most people who aren't exercising have resting heart rates of 70 or greater, even 80 or greater. Less heartbeats per minute means less work for your heart.
Aerobic exercise, done correctly, makes a person much healthier overall, positively impacting many body systems.
