Staying active can be a great way to fight fatigue.

Research shows that as little as 10 to 20 weeks of regular exercise may be enough to produce a marked improvement in energy levels, particularly for people who have medical conditions. Just remember to clear any new exercise plan with your healthcare provider first.

Medical conditions associated with fatigue include depression, anxiety, sleep disorders, chronic pain, and hypothyroidism (underactive thyroid). However, a new study reports that physical activity may help people with medical conditions increase their energy levels. Ideally, you should aim to get at least 30 minutes of moderate exercise (brisk walking, cycling, or swimming) every day. If this seems daunting, just start with 5 to 10 minutes of activity per day and work your way up. If you are exercising for the first time, or have a diagnosed health ailment, clear your plans with your healthcare provider first. Eating a balanced diet with adequate vitamins, minerals, and calories from a variety of food sources also can help stabilize your energy levels.
