When you go for a massage or esthetic treatment to relieve yourself of tiredness, you may find that your stiffness is relieved, you feel more comfortable, and your body feels lighter.

What are the benefits of massage and esthetic treatment?　

The fact that we are dealing with this topic here may make some of you think that oxidative stress is related to such things, but actually, it is not.

Why do we experience fatigue and stiff shoulders in the first place?　

About 100 years ago, an experiment showed that lactic acid in the body increases when the body gets tired, but at that time, it was assumed that lactic acid was the cause of fatigue without clarifying the details of its function.

However, recent research has shown that lactic acid is not a fatiguing substance, but a restorative substance, which is quite the opposite of what was previously believed.

It is now known that lactic acid is used as energy in the body. Lactic acid itself is not energy in its original form, but when it is converted into pyruvic acid, it is converted into energy in the mitochondria. In this way, lactic acid is a substance that can be used for energy, so it doesn't accumulate and become the cause of fatigue. It has also been said that lactic acid is the cause of muscle pain, but muscle pain is mainly caused by the tearing of muscle fibers during exercise, which is also not caused by lactic acid.

What is the real cause of stiffness?

So, if lactic acid is not the cause of physical fatigue and stiff shoulders, then what is the real cause?

There are times when muscles get stiff, shoulders get stiff, and balls of stiffness are formed, and it is still often thought that this is the result of muscles being stiffened by tension, resulting in impaired blood circulation and the accumulation of "lactic acid". Both physical fatigue and stiff shoulders are thought to be caused by the accumulation of lactic acid.

However, as I mentioned earlier, lactic acid was not the cause. And now, research has just begun to show that the cause of physical fatigue and stiff shoulders may actually be "oxidative stress substances".

There are many forms of massage, but I tested it with "Shiatsu massage". I found a phenomenon that when I gave a special acupressure massage, the stiffness  disappeared in a very fast time.

When we conducted blood tests on people regarding this phenomenon, the data showed that the oxidative stress levels were going down!  We hope to report on this detailed mechanism as soon as we know more about it in our future research.

Finally.

Last but not least, getting a proper massage or beauty treatment can be effective in reducing oxidative stress. When you feel tired and tired, it is a good idea to go for a massage or beauty treatment as a reward for yourself, because if you leave it as it is, oxidative stress may cause your body to rust.

Take care of yourself in moderation and you will be able to overcome fatigue and stress.
