To gain energy fast, try these effective methods:

• Take a short nap (around 20-30 minutes) to immediately boost cognitive function and alertness.
• Drink water to quickly counteract dehydration, which can cause fatigue.
• Eat a protein- and fiber-rich snack or a carb-rich breakfast to provide sustained energy.
• Do some light exercise or stretching to increase blood flow and oxygen to your brain and body.
• Practice fast breathing exercises like the "breath of fire" to stimulate energy.
• Avoid sugary snacks and drinks as they may cause an energy crash later.
  These strategies work quickly to restore energy levels naturally and safely without reliance on caffeine or sugar crashes.
