Our brain and our skin develop from the same group of cells
0:03
in the early embryo, and they're intimately linked.
0:08
When the brain is under stress, your skin can feel it, too.
0:12
Here's how humans evolved to feel stress as a natural response to threats.
0:18
In small doses, it can help us be more alert and react appropriately.
0:24
Stress can become harmful when we start to feel like you cannot control it,
0:30
or that it is unpredictable.
0:35
Stress activates the amygdala,
0:37
a part of the brain involved in primitive emotions.
0:40
This signals to a command center called the hypothalamus,
0:43
which triggers glands to make various hormones like cortisol and adrenaline.
0:47
These travel in the bloodstream all over the body, including to your skin.
0:52
We are wired from head to toe to feel stress.
0:57
As well as receiving hormones from the brain's stress response.
1:00
The skin releases its own stress chemicals too.
1:04
The skin will talk to your brain and your brain will talk to your skin.
1:07
And then the effects of those combined is what causes the skin changes that we can see.
1:17
The stress chemicals can boost inflammation
1:19
and reduce the fatty lipids that make up the outer skin barrier.
1:23
This can make the skin more porous, leaving it
1:26
feeling drier or more sensitive.
1:30
What we tend to lose from the skin barrier is important things like water.
1:34
We also can become more sensitive to things in the outside environment.
1:39
So for example, allergens like pollen
1:41
or someone else's fragrance get into the skin and cause irritation.
1:48
A number of small studies looked at stress and measured the skin barrier
1:52
by pulling a piece of sticky tape off the skin,
1:55
then seeing how quickly it recovers and stops water escaping in one study,
2:01
volunteers were told to deliver a speech,
2:03
then solve a maths problem in front of a hostile audience.
2:08
Their skin barrier recovered more slowly compared to
2:10
a non-stressed group who were asked to simply read an article on their own.
2:15
Stress also activates cells within the skin
2:17
to release chemicals like histamine that make you feel itchy.
2:21
Supercharging what's called the itch scratch cycle.
2:25
You feel itchy, you scratch, you cause further skin damage,
2:29
and that triggers you to feel even more itchy.
2:31
So you scratch again.
2:34
At the same time, stress reduces antimicrobial peptides in the skin.
2:38
Small molecules that normally kill off germs,
2:41
making infections like cold sores or shingles more likely.
2:44
What's more, the stress chemicals are thought to stimulate glands in the skin
2:48
to make more of an oily substance called sebum, which can contribute to spots.
2:53
This might be one of the reasons why
2:55
people with more stress also tend to have worse acne in various studies.
2:59
For example, one small study looked at medical students early
3:04
in the academic quarter and again just before an exam.
3:07
The more their stress increased, the worse their acne got.
3:11
Stress can trigger flare ups in other skin conditions
3:14
like eczema, psoriasis, and hives, too.
3:17
And while it's less researched, there is some evidence that stress might change
3:21
and reduce the amount of collagen and other building blocks of the skin.
3:26
Then technically, you can experience issues like loss
3:29
of firmness, loss of suppleness, increasing lines and wrinkles.
3:34
So what can you do about it?
3:39
Noticing the stressor is the first thing.
3:41
And and we can notice the stress on our skin.
3:44
You might feel some neck pain or your stomach in a nod.
3:48
Difficulty sleeping. Forgetting things. Irritability.
3:53
Experts say exercise, seeing friends,
3:56
and even meditation can help relieve the stress your brain's feeling.
4:02
But what about the skin?
4:05
Simple things that you can do yourself
4:08
are to think about your skin barrier in your normal skincare.
4:11
Looking for more hydrating products? For example,
4:14
if your skin is feeling dry, I normally recommend diets that are good
4:18
in healthy fats, lean proteins, fresh fruit,
4:22
and vegetables, making sure you're well hydrated.
4:26
Some experts say it can take three months to know if any treatments
4:30
or lifestyle changes are really improving the skin,
4:33
so consistency is important.
4:37
If you have a skin condition that is aggravated by stress,
4:40
it's of course important to address the stress element
4:43
and address the actual skin condition.
4:45
Skin is a manifestation of the health of your body.
