If you can’t have another cup of coffee, try it.
When the evil of the pig attacks you, you may be tempted to have a cup of coffee or a can of soda to reactivate yourself. However, a new study in Physiology & Behavior suggests that you don’t need caffeine to get an energy boost .
The researchers did two separate experiments with 18 women, chronically sleep deprived: in the first test, they took 50 milligrams (mg) of caffeine, which is slightly less than you would get in a can of soda. In the second, they went up and down stairs at a steady pace for 10 minutes.
The researchers found that the participants felt significantly more energy after climbing the stairs than they did after taking the caffeine (and felt the renewed vigor immediately after exercise).
The researchers also examined the participants’ memory and their reaction time after completing the tasks. They found no difference between them with the caffeine experiments versus the stairs, showing that physical activity can increase your physical energy without draining your mental energy .
Now, the study was done with women, so it’s not entirely clear if the same effects would apply to men. Nevertheless; trying to be physically active during the day will never have any disadvantages.
