In conclusion, saunas have many benefits that have a positive effect on the body.If you experience symptoms such as losing consciousness or feeling unwell during the sauna, there is a high possibility that there is a problem with the way you enter the sauna.In order to get the various benefits from a sauna, you need to learn how to use it correctly.
A sauna warms your body by bathing in hot air at a high temperature (80 to 90 degrees) and provides various benefits.We will explain 11 benefits of using a sauna in order.
One of the benefits of saunas is that they promote blood flow.It is said to be nearly twice as strong as at rest, and has the effect of increasing the amount of oxygen carried in the blood and secreting substances that cause muscle fatigue.Since it regenerates energy in the body, you can expect a fatigue recovery effect.
Another great thing about it is that it helps relieve fatigue not only for the body but also for the mind.When you warm up in the sauna, your muscles will release tension and your blood vessels will relax.As a result, palpitations are relieved and anxiety and stress are relieved.
When you enter a sauna and the hot air stimulates the skin all over your body, your central nervous system becomes activated.It is said that it also promotes the adjustment of bodily functions by the nervous system, leading to stress relief.
Immediately after entering the sauna, blood pressure increases temporarily, but afterward, both systolic and diastolic blood pressure decrease due to the dilation effect of blood vessels.There is also an overseas paper (*) that shows that regular use of a sauna is effective in preventing high blood pressure.However, saunas can put a considerable strain on the heart and blood vessels, so if you already have high blood pressure, you should consult your doctor before using a sauna.

In particular, saunas with low temperatures can help you sleep better.Slowly entering the sauna has a sedative effect.Your body switches from an active rhythm during the day to a restful rhythm at night, improving the quality of your sleep.To get a good night's sleep, it's best to sit on the lower level of the sauna room.This is because warmed air has a tendency to rise, so it becomes colder at the bottom.
When sauna promotes blood circulation, it has the following effects on muscles.
Due to the above effects, it is said that it can be expected to improve neurosensory symptoms such as muscle-related stiff shoulders and muscle pain, as well as lower back pain.
When you take a sauna, you sweat a lot, so when you weigh yourself after taking a bath, you may have lost about 1 kg.However, the weight loss effect of saunas is temporary.What is important is the improvement of metabolism by increasing body temperature and the effect of discharging lactic acid, which inhibits fat burning.By combining exercise and diet changes with a sauna session, you will be able to achieve a diet effect.
A series of temperature changes such as saunas, cold baths, and outdoor air baths increases the ability to regulate the autonomic nervous system and improves blood circulation in the capillaries.
When you enter the sauna, your pulse rate will gradually increase.The increase in pulse rate is due to an increase in the amount of blood pumped by the heart.By increasing blood output from the heart, oxygen and nutrients are more efficiently supplied throughout the body.
Work up a sweat in the sauna, or cool down in a cold bath or shower.Furthermore, the experience you get while taking a break in the open air is often described as ``settling'', and some of you may have heard of it.The autonomic nervous system consists of two parts: the sympathetic nervous system and the parasympathetic nervous system.In a hot sauna or cold water bath, the sympathetic nervous system becomes dominant (an excited state), while in an open air bath, the parasympathetic nervous system becomes dominant (a relaxed state). condition).A state in which these two coexist is ``adjusted''.
A bathing method that uses both a sauna and a cold bath to "condition" is called "alternate bathing," and it works on both the sympathetic and parasympathetic nerves and is a training exercise that trains the autonomic nervous system.
It is said that when a human's body temperature reaches approximately 38 degrees, sweat is produced from sweat glands all over the body.By sweating in a sauna, you can also remove sebum and dirt accumulated in your pores and apocrine glands, cleaning your skin and subcutaneous tissue.
When you enter a sauna and your body temperature exceeds 38 degrees, a protein called HSP (heat shock protein) is produced. HSP is a substance deeply related to the human natural healing power that has the function of restoring damaged proteins.
Most cells in the human body are made of protein.HSPs are also produced at the same time that proteins within cells are damaged.High fever, fatigue, heat and cold.Furthermore, HSPs are responsible for repairing damage to cells caused by various stresses such as ultraviolet rays.If you can increase your HSP by taking a sauna, it will lead to increasing your natural healing power.

Although saunas have advantages, they also have disadvantages.
What you especially want to remember is that saunas are taxing on your body.When you use a sauna, the stress on your body is similar to that of a light exercise.Naturally, if the frequency and time you use the sauna increases, the load will naturally increase.If you use it too much, it can become such a burden that it interferes with your daily life and work.
Also, using the sauna for long periods of time can lead to dehydration and heat stroke.Heat shock is a phenomenon in which rapid changes in temperature cause blood pressure to rise and fall, causing heart and blood vessel disease, and saunas can also cause this phenomenon.If you have a chronic illness or have high blood pressure, we recommend that you consult your doctor before using this product.
Influenced by the sauna boom in recent years, ``Sa-katsu'', such as having a relaxing experience in a sauna and enjoying sameshi, has become popular.There may be many people who want to enjoy sa-katsu as a date for couples.Couples can enjoy sauna together, but men and women are generally not allowed to enter the sauna room together.By not going into the sauna room together, there is often a time lag between the sauna, cold bath, and outside air bath, which has the disadvantage of not being able to enjoy the sauna together.
In order to eliminate the disadvantages of saunas, we will explain the countermeasures you should know.
Please use the sauna as much as you can, depending on your physical condition.You should refrain from using the sauna if you are extremely tired, lack sleep, or have consumed alcohol.
If you experience unusual symptoms such as a headache, lightheadedness, or dizziness while taking a sauna, immediately stop using the sauna and take a rest in a cool place.If your symptoms do not subside, seek help from those around you.
When you sweat in a sauna, both water and salt are removed from your body.Before and after the sauna, drink around 300 to 500 milliliters of a drink containing electrolytes, such as mineral water or salt.It is important to stay hydrated before sauna even if you are not thirsty.
Many people like to drink alcohol after sauna.However, it is strictly prohibited to drink alcohol or anything containing caffeine, such as coffee, before or immediately after taking a sauna.These drinks have a diuretic effect, making it easier for your body to eliminate water.If you want to enjoy alcohol, make sure you are well hydrated and rested.
There are also saunas that you can enjoy in a private space without other customers.If you want to enjoy a sauna as a couple, use facilities and services that allow you to use the sauna in a private space.For example, some glamping facilities have saunas that can be used in private spaces, such as private saunas or saunas for guest rooms.What's more, with the in-room sauna, you can enjoy the sauna whenever you like during your stay.
