Water has always been a source of pure health. One of the interesting benefits of water is the effect of the cold shower on our bodies. Cold water is an ancient remedy for different conditions, like bad blood circulation or slow metabolism. In the 1920's it was developed into a whole medical movement, called hydrotherapy (therapy by water) and it was successfully used to treat medical conditions and improve the overall heath. With the upgrade of the medicine over the years, these techniques have been left in the past, but it wont hurt to know their benefits. As a mater of fact, I practice the cold shower personally, almost every day, and I can vouch for its benefits. Learn some more of that a simple cold water can do for you.
1. Stronger Immunity
Cold showers have been used as a preventive tool for colds, flu and some infections. Researchers believe that the increased metabolic rate, which results from the body’s attempt to warm itself up, activates the immune system and releases more white blood cellsin response. Therefore, it is reasonable to assume that people who take regular cold showers are less likely to develop colds, flu’s, and even some forms of cancer.
2. Better Blood Circulation
Good blood circulation is vital for overall cardiovascular health.Alternating between hot and cold water while showering, is an easy way to improve circulation. There is a medical term for this process, vasoconstriction, which means that the blood vessels are being tightened to help blood to flow at a higher pressure, or improving of the blood circulation. The natural tendency of the body when it is exposed to cold is that your blood rapidly circulates to your vital organs to keep them warm, hence increasing your over all blood circulation. Good circulation improves the performance of your system and thus help looking and feeling better.
3. Regulates Temperature
Cold showers provide a gentle form of stress that leads to thermogenesis (internal generation of body heat), which in turn activates the body’s adaptive repair systems. If you suffer from chronically cold hands and feet, or feel that you sweat an abnormal amount, try a cold shower.
4. Faster Metabolism/ Easier Weight Loss
Brown fat, as opposed to white fat is heavily involved in burning energy. Exposure to cold naturally stimulates the production of these brown fats. These cells burn glucose to try and produce as much heat energy as possible. Having a higher amount of brown fat leads to more energy being burned per second and therefore, more weight is lost. As a result of the increased brown fat levels, and the increased blood pressure and body temperature, chemical reactions in the body will happen faster than they would have without regular cold showers. An increased metabolism is what a lot of people seek for because it means that any process in the body will become more efficient; meaning more weigh loss will be seen and more growth/repair of muscles and otherwise will be seen.
5. Better Lymphatic Movement
The lymphatic system is a system of tubing separate from our blood vessels that is responsible for carrying away waste from your cells as well as help fight pathogens (disease). Unlike blood vessels, the lymphatic system does not have blood, it has lymph, which carries away waste products and white blood cells which handle infection. Also different from blood vessels is that the heart does not pump lymph around the body like it does the blood. The lymph relies on the contraction of muscles. This contraction squeezes the lymph up to the thoracic duct so that the lymph can mix with the blood and then be dealt with by organs. Cold showers cause whole-body contraction and this works excellently with the lymph system, squeezing the fluid up through the body. If the lymphatic system is compromised and not efficient, then the fluid pools at faraway places (usually the feet). This results in what is known as lymphedema (a type of edema).
6. Deeper Breathing
What you will notice as an effect of cold showers is that you begin inhaling very deeply. This is to try and combat the stress of the shock, the vasoconstriction and the overall need for oxygen to respire and keep oneself warm. This process opens up the lungs much like strenuous physical exercise does and results in a higher average intake of oxygen, which is good for many things like not feeling tired during the day and doing better at sport or other exercises.
7. Healthier Skin and Hair
It is well known that hot water dries out our skin and hair. On the other hand, cold water can make our hair look shinier and our skin look healthier by tightening cuticles and pores, preventing them from getting clogged, thus reducing blemishes like acne. Cold water also contributes to detoxification which results in the squeezing of toxins and waste products out of the skin. This detoxification has a good effect on the skin which appears more clean and young. Additionally, the cold water closes the cuticle which makes the hair stronger and prevents dirt from easily accumulating within our scalp. Stronger hair, of course, prevents hair from easily falling out and it helps in slowing down overall hair loss.
8. Higher Energy and Well-being
There are plenty of mental benefits to ending your shower with cold water. The ancient samurai warriors used to pour buckets of cold river water on their heads every morning in a Shinto practice called Misogi. This was a purification ritual on a spiritual level. They believe that it cleansed their spirit and helped start a fresh new day. A cold shower can definitely leave one feeling invigorated and energized. The heart starts pumping, and the rush of blood through the body helps shake off the lethargy of the previous night’s sleep. Additionally, while there are not many studies to confirm, many people swear that cold showers are a definite stress reducer.
9. Increased Hormone Production
Cold water showers have the ability to increase hormone production and activity by giving the body’s glands a boost. For example, cold showers can be of great benefit to the reproductive system when trying to conceive a child. A man’s testes are not meant to get too hot; that’s why they hang outside of a man’s body. Sperm counts decrease when the temperature of a man’s testes increases. In fact, experiments done in the 1950s showed that hot baths were an effective contraceptive. Men who took a 30 minute hot bath every other day for 3 weeks were infertile for the next six months. More recently, the University of California at San Francisco did a study with men who were exposed to 30 minutes of “wet heat” (hot baths, saunas and such) a week. When the men cut this exposure out, their sperm count went up by 491%, and their sperm’s motility improved as well. While switching from a hot to cold shower may not have as dramatic an effect, if you’re trying to reproduce, it surely won’t hurt. Furthermore, it has been said that cold water therapy helps regulate the endocrine system (including the adrenals and thyroid).
Start small and easy
To start practicing cold showers, it is recommended to gradually adjust from hot to cold showers. For many, a drastic change in temperature would be too much a stress to their body. Push yourself to step outside your comfort zone, while at the same time listen to what your body can handle. A great way to implement cold showers into your daily routine is by turning the water to cold for the last 30 seconds to a minute of your shower. Give it a try and see what benefits you experience. Who knows, maybe the secret to the fountain of youth is hidden within cold showers. The good things in life are simple, make good use of them ;)
