What is the science behind a sudden burst of energy without any external influence

18 March 2019

 

Have you ever experienced a sudden increase in energy even though you are tired? Well, you are not alone. Most people experience an increase or a decrease in their levels of energy to perform a task. There are many reasons behind this phenomenon, some of which have been mentioned below.


Recovering from a cold or a mild fever:
 

The effect of virus that causes a mild fever or a cold leaves the body tired, but, soon after you recover from the effects of these diseases, your immune system stops hogging the energy from various sources. This may result in a sudden burst of energy. It is more commonly experienced by people who are cured by antibiotics.

 

Increase or Decrease in thyroid production
 

A person may experience a sudden burst in energy due to an increase or a decrease in thyroid level.

 

Release of growth hormones
 

Growth hormones are released in occasional bursts. The effects of release of growth hormones are usually felt after 24 hours. The energy released is noticeable more in people over the age of 30, since the release of growth hormones is less frequent at that age.

 

After the first stage of digestion

 

If you have a light afternoon meal and don’t indulge in any physical activity after it, you will feel the need to move around after an hour or so. This happens mainly after ingestion and as soon as the food enters the digestion phase when the food is being broken by the acids.

 

Adrenaline

 

This is the most common reason why one gets a sudden burst of energy. Technically, adrenaline, also known as Epinephrine acts by linking to adrenergic receptors. Epinephrine is an agonist and is nonselective. You may experience an adrenaline rush at a pleasant surprise or when you need to beat a deadline.
