8 Ways to Boost Your Energy

Enjoy some java.

Caffeine is currently the most widely used stimulant in the world, and scientific studies confirm that caffeinated beverages like coffee can help keep you temporarily alert and focused. So feel free to enjoy a few cups of joe, but certainly know your personal tolerance level — an eight-ounce cup of coffee has approximately 100 mg of caffeine; a cup of green or black tea has around 40 mg — and don’t rely solely on caffeine as your means to stay energized. What’s more, be sure to “decaffeinate” by late afternoon so the caffeine doesn’t keep you awake at night (remember, you want to get seven to nine full hours of sleep!). The jolt from caffeine typically peaks within the first hour and can linger in your system between three and eight hours, so adjust accordingly.
