Low iron levels:
About 12% of American women and 7% of men have an iron deficiency,
which leaves you feeling drained and lethargic. In Spinning classes,
this effect may even be worsened, since you're indoors, focused on your
heart rate monitor, and literally not moving. Vegetarians,
dieters and athletes are at an increased risk. Iron-rich foods such as
meat, beans and cereals can keep iron levels high. To maximize
absorption into your system, they are best consumed with a food high in
Vitamin C. You can also purchase over-the-counter iron pills or
multivitamins with iron. However, you may want to consult your doctor
due to some small risks associated with the onset of too much iron in
your system.
Low blood sugar:
Food is energy. If you regularly skip meals—especially breakfast —you
are going to pay dearly for it. In addition, meals should be
well-balanced with the proper amount of carbs, protein and fats. Take a
serious look at your diet, and make lifestyle changes.
Medications: Many
drugs, including blood pressure medication and some birth control
pills, can affect energy. Antibiotics can cause strange fluctuations in
your strength. If you suspect that your medicine is zinging your
stamina, check with your doctor about making a switch.
Poor sleep: Are
you trying to survive on six hours of sleep? Quit it. Does your spouse
snore? The quality of your sleep can have as much of an impact as the
quantity. We often have to make a conscious effort to get in bed an
hour earlier. This may be tough at times but will make you a much
better athlete ... and person. Turn down some of those engagements so
you can turn down the sheets.
Unrecognized allergies: Histamines
and other chemicals released by an allergic reaction can make people
feel tired. Allergies can also interfere with breathing, which deprives
your muscles of rich oxygen.
Dehydration:
Are you getting enough water? Eight glasses plus? Think about it this
way: your blood is practically 80 percent water. If you are dehydrated,
it gets really thick and can’t move around your body as effectively to
feed your muscles with much needed oxygen. Then your heart has to pump
much harder. Drink more.
Depression:
Even mild forms of depression (e.g., from lack of sunlight) and anxiety
are associated with low levels of serotonin, a chemical in the brain
that can affect energy and mood. You may want to seek professional help
if you think your tiredness may be associated with depression.
Overtraining:
Are you doing too much? Have you followed a hard/easy regimen or are
you constantly pushing yourself day after day with no plan, no goal?
What’s the use if you are going to feel like this? Keep a journal of
your daily workouts. Refer to it often to see if you are following a
structured plan.
