What is Cortisol? ~The 'Stress Hormone' You Need to Know About to Protect Your Brain~ [Read or Listen in 1 Minute: Brain Science Keywords ~Health Edition~]

▶Click here to watch the video

When you feel stressed

your brain secretes a hormone

called 'cortisol'.

This plays an important role

when we face a crisis

by temporarily increasing focus

and generating energy.

It is, so to speak, a hormone

that acts like 'first aid'

to protect the brain and body during emergencies.

However, research has shown that

if this cortisol continues to be secreted

over a long period of time,

it can have a negative impact on the brain.

In particular,

it damages nerve cells in the 'hippocampus'

and 'prefrontal cortex' involved in memory and emotion,

leading to a decline in memory

and emotional instability.

It can become a cause that triggers it.

Furthermore, cortisol

can cause inflammation in the brain

and is also considered to be related

to structural changes known as atrophy.

Therefore,

if you feel 'vaguely tired'

or 'unable to concentrate on things'

and these states persist,

it is worth considering

the influence of stress and cortisol.

Managing stress well

and preventing the excessive secretion of cortisol

is the key to protecting brain health.

Exercise,

breathing techniques,

sufficient sleep,

and human connection—

all of these are simple,

but daily practice

It brings about significant effects.

The significance of learning brain science keywords

By understanding how the brain works, you can improve your learning efficiency

and discover ways to reduce stress.

Acquire knowledge based on scientific evidence

and put it to use in your daily life.
