Skipping your workout to save energy actually works against you. Regular exercise boosts strength and endurance, helps make your cardiovascular system run more efficiently, and delivers oxygen and nutrients to your tissues. - Being even slightly dehydrated takes a toll on energy levels, says. Dehydration causes a reduction in blood volume, which makes the blood thicker. This requires your heart to pump less efficiently, reducing the speed at which oxygen and nutrients reach your muscles and organs.

- Constant blood sugar spikes followed by sharp drops cause fatigue over the course of the day. Keep blood sugar steady by having a lean protein along with a whole grain at every meal.

This is why you're more likely to wake up in the middle of the night after you've been drinking.
