You follow a proper skincare routine every day.
You wash your face, apply toner, and use lotions and serums.
Even so, do you ever wake up in the morning and feel like your skin just isn’t quite right?

Your skin feels dry.
Your face looks tired.
You are concerned about skin roughness.

In such cases, reviewing your skincare products is one approach.
However, when considering the condition of your skin, it is not just skincare that matters.

Last time, we introduced the importance of looking at your daily diet regarding the relationship between food and skin.
And this time, we will turn our attention to another lifestyle habit: sleep.

Skin is a part of the body.
Just as daily meals provide the materials to build the body, sleep is essential for resting the body and maintaining its condition.
It is not just about “what you use,” but also “what you eat” and “how you sleep.”
If you are thinking about your skin, try looking at your daily lifestyle habits along with your skincare.

■ Skincare and sleep. They have different roles to begin with.

■ Skincare and sleep. They have different roles to begin with.

Both skincare and sleep are important when thinking about your skin, but their roles are not the same.
Skincare is care performed from the outside of the skin.
You wash away dirt and excess sebum, and maintain skin moisture with toners and lotions.

On the other hand, sleep is essential for resting the body and maintaining the condition of both mind and body.

In other words, it is not the case that “because I am doing skincare, it is okay if my sleep is a bit short.”

Conversely, it is also not the case that “if I sleep well, I don’t need skincare.”

Caring for the skin from the outside and letting the body rest properly.
Because each has a different role, it is important to consider both.

■ Are you sleeping well every day?

Let’s take a look at one man’s day here.

7:00 AM
Wake up.
I can’t get up even when the alarm goes off.
I was looking at my smartphone until past 1:00 last night.
↓
8:00 AM
Get ready in a hurry and head to work.
↓
7:30 PM
Finish work and return home.
↓
9:00 PM
Watch videos while eating dinner.
↓
11:30 PM
Take a bath and do skincare.
Apply toner and lotion.
↓
12:30 AM
Get into bed, but start looking at the smartphone.
↓
1:30 AM
Finally go to sleep.

Is this person okay because they do skincare every day?
Of course, just because your sleep time was short for one day does not mean that alone determines the state of your skin.
However, what if this lifestyle continues for days or weeks?
Lack of sleep affects the entire body’s condition, such as daytime sleepiness and fatigue.
And various studies have been conducted on the relationship between sleep and skin condition.
When you feel that “my skin condition hasn’t been great lately,” instead of just looking at your skincare products, try looking at your sleep time as well.
That is also one way to face your skin.

■ What is happening in the body while you sleep?

During sleep, the body is not just resting.
While you sleep, hormones such as growth hormone are secreted, and various functions related to repairing damage received during the day and maintaining the body are performed.

Of course, skin is no exception.
During the day, the skin is exposed to various stimuli such as ultraviolet rays and dryness.
Since these functions related to body recovery are performed during sleep, if sleep time is insufficient or the sleep rhythm is disrupted, it may affect the skin’s condition.
In fact, the link between lack of sleep and skin barrier function or visual impression has also been studied.

For example,
・You are concerned about skin dryness
・Your skin condition is unstable
・Your face looks tired
・You are concerned about skin roughness

When that happens, it is a good idea to look back not only at your skincare routine but also at your daily sleep habits.
However, the condition of your skin is not determined by sleep alone.
Various factors are involved, including diet, stress, ultraviolet rays, hormones, genetics, and skincare.
That is why it is important to think about your skin in the context of your entire daily life, rather than jumping to the conclusion that “bad skin equals lack of sleep.”

■ “Sleeping longer” is not necessarily better

So, for the sake of your skin, should you just sleep as long as possible?
That is not necessarily the case.
What is important is to ensure you get the amount of sleep you need and to create as regular a daily rhythm as possible.

While 6 to 8 hours is generally considered a guideline for adult sleep, the amount of sleep required varies from person to person.
It is not as simple as saying, “If you sleep for 8 hours, your skin will definitely become beautiful.”

Do you feel well-rested when you wake up in the morning?
Do you feel strong sleepiness during the day?
Let’s start by getting to know your own sleep state.

■ The “time before bed” that is surprisingly easy to overlook

How you spend your time before bed is just as important as ensuring you get enough sleep.

For example,
・Looking at your smartphone after getting into bed
・Continuing to work late into the night
・Going to bed at different times every day
・Consuming a lot of caffeine after the evening
・Looking at a bright screen right until you go to sleep

Do you have any of these habits?
Smartphones, in particular, tend to make you lose track of time once you start watching videos or checking social media.
You might think, “I’ll just look for a little bit,” but before you know it, 30 minutes or an hour has passed.
As a result, your bedtime may end up getting later and later.
If any of this sounds familiar, try putting your smartphone away at least 30 minutes before bed.
Starting with such a small adjustment is a good idea.

■ Can “sleeping in” solve weekday sleep deprivation?

You are busy with work during the week and your sleep time is short.
To make up for it, you sleep until noon on your days off.
There are probably people who live like that.
Sleeping longer on your days off can reduce sleepiness and fatigue caused by lack of sleep.
However, sleeping a lot on your days off does not mean you can make up for all the sleep you missed during the week.
Rather than continuing a lifestyle of “short sleep on weekdays, sleeping in on weekends,” it is important to ensure a stable amount of sleep on a regular basis.
You don’t need to live a perfect life every day.
Let’s start by trying to secure even a little more sleep during the week.

■ Thinking about how you “sleep” today for the sake of your skin

When you are worried about the condition of your skin, you tend to focus on skincare products.
But your skin is a part of your body.
That is why you should also look at your daily life itself.

How many hours did you sleep today?
Have you been resting properly lately?
Is your bedtime getting later?

You don’t have to change everything at once.
Put your smartphone away a little earlier than usual.
Go to bed a little earlier than usual.
Even such small changes can be the start of reviewing your lifestyle habits.

Skincare is something you do every day.
And sleep is also something you repeat every day.

Improving your diet and ensuring you get enough sleep—neither one alone determines the state of your skin.
It is not just about “what you use,” but also “what you eat” and “how you sleep.”
Why not start being mindful of what you can do for your skin, starting today?
