Tiredness throughout the day can be caused by a variety of reasons. Not getting enough sleep, eating a large breakfast/lunch, skipping meals, stress, dehydration, sleep disorders, and other medical conditions can be common culprits. Getting a cup of coffee or other caffeinated drink (such as soda or energy drinks) will actually not help the problem as much as you would think. Instead, grab a drink of water or try to keep a water bottle with you to avoid dehydration and re-energize. If you’ve skipped a meal, try to find a snack. Fruit and nuts can make a great pick me up if you’ve missed breakfast or lunch. When you do have meals and snacks don’t over indulge, and try to select a plenty of fruits, vegetables and whole grains. Poor nutrition can also lead to tiredness.
If skipping meals and dehydration aren’t the cause, get up and move around for a few minutes. About 10 minutes should do the trick. Or try aromatherapy; orange peel, peppermint or rosemary oils can get you going again. If none of that works, then try having a healthy snack.
If you repeatedly have daytime tiredness and you are sleeping enough (7-8 hours a night), there could be an underlying medical cause, and in that case, you should see your doctor.
