What does adrenaline/epinephrine do?

One of the main hormones that help you in dangerous situations is adrenaline. This hormone performs many functions that might even help you save your life in extremely stressful situations.  

Learn more about adrenaline and its functions in this article.  

Adrenaline hormone is produced by the center (medulla) of adrenal glands (which are located at the top of your kidneys). Your bodies produce adrenaline to respond to ‘fight or flight’ situations. This hormone is released with another hormone noradrenaline in the bloodstream to send signals (neurotransmitters) from neurons to various organs to perform various functions such as increasing glucose in the bloodstream, increasing heartbeat, breathing, sensory awareness, etc. 

Functions of Adrenaline 

There are many functions that adrenaline performs to respond to fight or flight situations, including: 

  • Increases heart rate so that your body can pump more blood into the vessels. 
  • Increases blood pressure so that blood flows faster from your vessels into the vital organs. 
  • Expands the air passages in the lungs to ensure more oxygen intake.  
  • Enlarges pupils (of the eyes). This is the natural response of the eyes whenever it gets exposed to too much light.  
  • Decreases your sensitivity to pain and that’s the reason you don’t feel pain in those kinds of situations. 
  • Improves your vision and helps you see clearly in tough situations. 
  • Improves hearing and other senses that helps to listen clearly and sense danger in life-threatening situations.  
  • Slows the digestion process and helps you keep more energy in the body and use energy only for necessary processes. 
  • Redistributes the blood to muscles and other organs and helps to maintain the energy in muscles to use in those situations. 
  • Alters the metabolism to help you to have more energy to perform different tasks.  
  • Increases blood sugar levels which helps to provide more oxygen and nutrients in the body to take certain actions. 

What happens when your body secretes adrenaline? 

Your body secretes adrenaline when you encounter stressful situations. When adrenaline is released in the bloodstream by adrenal glands, your body starts to feel energetic, your brain feels lighter, vision seems clear and sharp and time feels a little bit slower, the body feels less pain, and your heart rate and breathing increase, etc.  

Until the stressful situation ends these feelings, senses, and energy stay in your body. Once it’s over, your body starts feeling down and tired due to the overuse of its energy sources.  

Adrenaline hormone is very important for your body and with the help of this hormone, your body gets the energy, and awareness so that you can survive in stressful situations. If the level of this hormone runs high due to any reason, it can be harmful to you because it can cause health-related problems such as heart damage, insomnia, and jittery or nervous feelings most of the time. So, it is important that you maintain hormonal health.
