Although caffeine remains the preferred stimulant for those seeking an extra energy boost, it is not without its downsides.
Caffeine can cause a sudden spike in blood pressure, and for those with severely high blood pressure, drinking two or more cups of coffee a day may double the risk of death from a heart attack or stroke, according to the American Heart Association.
Caffeine is also not recommended for pregnant women, because it travels through the bloodstream and can reach the placenta, where it may increase the fetal heart rate and accelerate metabolism.
Experts point out that caffeine can be dispensed with to get an energy boost with minimal physiological side effects, through aromatherapy, which has proven to be safe and effective.
Experts suggest three specific scents that can invigorate the mind and body:
A scientific study has shown that inhaling lemongrass essential oil for just five minutes can significantly improve cognitive functions, memory, and attention.
Recent research has also proven its effectiveness in lowering blood pressure and heart rate and reducing anxiety, especially in patients awaiting medical procedures.
Peppermint oil has numerous scientifically proven benefits, including increased alertness and enhanced memory. Most interestingly, it also helps reduce aggressive driving behavior, thanks to its compounds that positively affect mood and stress management.
The Greeks used rosemary centuries ago to enhance memory and concentration, and today scientific research confirms these benefits.
Studies have shown a marked improvement in anticipatory memory in older adults, and greater brain wave activity has been observed after inhalation.
The plant contains neuroprotective compounds that may contribute to the prevention of degenerative diseases.
Rosemary has additional health benefits, as its oil is used as a natural remedy to stimulate hair growth and prevent premature graying, and studies have proven its effectiveness to be comparable to some specialized medical preparations.
