Soaking in a hot tub brings many health benefits. After a few minutes in the tub, blood vessels will dilate, which lowers blood pressure. Soaking also provides buoyancy, reducing the workload for your body and heart by 10 percent to 20 percent. As the body goes through this process, muscles relax, temporarily relieving pain. The body begins sweating, riding toxins. The heat and pressure from the jets raise the level of antibodies and white blood cells, promoting the healing process.
HydrotherapySimply put, hydrotherapy is the therapeutic use of warm water - a proven, natural remedy. Whether it's to unwind from the complexities of everyday life or to rejuvenate sore muscles and joints caused by sports or arthritis pain, hydrotherapy can help you feel better - naturally.
How Does Hydrotherapy Work?There are three factors at work in a spa: heat, buoyancy and massage. Together, they create an experience that is both relaxing and healing. Immersion in hot water raises the body temperature and causes the blood vessels to dilate, resulting in increased circulation. The buoyancy of the water reduces body weight by approximately 90%, relieving pressure on joints and muscles and creating the relaxing sensation of weightlessness. The massaging action of a spa is created by sending a mixture of warm water and air through jet nozzles. This "energized" stream of water relaxes tight muscles and stimulates the release of endorphins, the body's natural pain killers.
Who Needs Hydrotherapy?
In a word, everyone. Soaking in the hot, swirling water of a spa leaves you feeling both mentally and physically relaxed. Ever have trouble getting to sleep? Fifteen minutes in a spa before bedtime can make it easier to drift into a deep, restful sleep. If you've ever felt stiff or sore or tense (and who hasn't?), you'll appreciate hydrotherapy. Many arthritis sufferers find that a soak in the morning provides day-long relief. And anyone who engages in strenuous sports, hard physical labor, or just spends the day on their feet can find relief in a spa, too.
Of course, a spa is more than just good hydrotherapy. It's also good fun. So it's something you'll want to experience every day. And once you own an Alberta Home Spa, you'll probably find yourself echoing what so many of our customer tell us. "I don't know how to I got along without it."
The Physiology of Hot WaterFrom the moment your body becomes immersed in a warm spa, it begins to experience mild changes that make you feel better...
Dipping your body into water of any temperature makes you feel weightless and, because of a change in hydrostatic pressure, can help dull any pain you may be feeling. But what separates soaking in a hot spa from treading water in a pool -- or even soaking in a warm bath -- is the fact that the warm temperature is sustained. Medical experts say that, over time, this brings about changes in your circulatory system that affect other aspects of your body's operations.
Your body's first reaction to being immersed in hot water is to try to get back to its normal temperature by pumping the heart faster, so as to bring blood to the surface and, normally, disperse extra body heat into the air. This causes a temporary increase in blood pressure.
But because spa water is maintained at a high temperature -- and because water is one of the most effective conductors of heat - the blood being carried to the body's surface is warmed, rather than cooled. The longer the soaker remains in the spa, the more times the blood cycles through the body -- and the deeper into the body the warm temperature is carried. Studies have shown that immersion in a spa maintained at 104 degrees can raise the core body temperature to 102 degrees Fahrenheit in less than 20 minutes.
After a few minutes, the warm blood causes the blood vessels to dilate, lessening the resistance to blood flow and dropping the blood pressure. As the body goes through this process, several benefits are enjoyed -- most of which are enhanced further by the jet action:
Muscle relaxation : This occurs when the warm blood reaches deeper and deeper into the muscles, causing the vessels to expand. The muscle-relaxation effects of hot water also help deaden muscle pain by easing any pinching of nerves or blood vessels, and by helping the muscle rid itself of lactic acid and other metabolic wastes.
Temporary pain relief : As the body tries to register a temperature change, the central nervous system becomes depressed, contributing to muscle relaxation and temporarily relieving, or at least lessening, pain. This can happen with any drastic change in temperature -- hot or cold -- but most people are more comfortable sitting in warm water than holding an ice pack. (Remember, for recent injuries where there is swelling or broken skin, an ice pack is more suitable.)
Bodily cleansing : In trying to regain its normal temperature, the body will begin sweating so that moisture on the skin will evaporate and cool the body. But this process also helps rid the body of toxins.
Priming the muscles : By relaxing muscles, hot water helps increase their range of motion to allow for gentle exercise and stretching in the spa.
Promotion of healing : The jet action found in spas can promote healing by providing even more oxygen to the area than is provided by warm water alone. The heat and pressure from the jets can also raise the level of antibodies and white blood cells delivered to the area, promoting the destruction of bad cells and stimulating the formation of new tissue.
Help for insomnia : It has been found that sleep deepens as body temperature falls. As a result, some medical experts recommend that anyone wanting to induce sleep (especially those being kept up by pain) soak in water of approximately 103 degrees Fahrenheit about two hours before bedtime.
Please note: You can, of course, get too much of a good thing. Soaking in a spa raises your core temperature without discomfort. This isn't healthy for more than a brief period -- and for some people it's not OK at all. The hot-water industry recommends that you soak no longer than 15 minutes at a time, refrain from performing rigorous exercise in hot water, and, if you have a medical condition, consult your doctor before taking a dip
Sleep Better with Spa TherapyRelaxing in a Hot Tub Can Help Ease Your Body into a Deeper Sleep
Sleep researchers believe that many cases of insomnia can be traced to hectic, stressful lifestyles lived by basically healthy people. The results of sleep deprivation are varied and may cause battered nerves, grogginess, lapses in memory, depression, and even erratic mood swings. Rather than reaching for over-the-counter sleeping aids, a simple solution to this dilemma may be relaxing in a hot tub before bedtime.
Studies suggest that immersion in hot water (such as a hot tub which has a constant temperature) before bedtime can ease the transition into a deeper, more restful sleep. This may be due to a temperature shift since the body's core internal thermostat drops after leaving the water, which signals the body that it's time to sleep. Or, the sleep improvement may also be related to hot water's relaxing properties -- the buoyancy of water reduces body weight by approximately 90%, relieving pressure on joints and muscles creating the sensation of weightlessness. The hot, swirling water leaves you feeling both mentally and emotionally relaxed.
In addition, many healthful benefits are derived from sophisticated, state-of-the-art hot tubs. The massaging action -- creating by sending a combination of hot water and air through jet nozzles -- results in an energized stream of water that loosens knots of tension and can provide a variety of therapeutic benefits including relaxing tired and aching muscles, easing arthritis pain, improving circulation, and increasing mental acuity.
Help Control DiabetesRecent studies published in the September 16, 1999 issue of the New England Journal of Medicine give new hope to the millions who suffer from diabetes. It stated that "hot tub therapy" helped a group of Type 2 diabetics reduce their blood sugar levels and improve sleep patterns. The effects of partial immersion in a hot tub simulate the beneficial effects of exercise. Physical exercise is recommended for patients with type 2 diabetes mellitus.
An independent study led by Dr. Philip L. Hooper at the McKee Medical Center in Loveland, Colorado studied a group of Type 2 diabetes patients for three weeks. The patients were required to soak in a hot tub for thirty minutes a day, six days a week, for the duration of the study. The results were astounding! The patients' average blood sugar levels were reduced by an average of 13 percent. Hooper also explained that one of the subjects was able to reduce his daily dose of insulin by 18 percent after only ten days of the study.
In reference to these findings, Dr. Hooper states that hot tubs are especially helpful for patients who are unable to exercise, and recommends that hot tub treatments should be included as regular therapy for patients with diabetes.
*IMPORTANT NOTE* It is highly recommended for those with diabetes to consult with their physician prior to beginning hot tub treatments.
Cardiovascular BenefitsA study at the Mayo Clinic found that since bathing in your hot tub simulates exercise, soaking in one gives you the same health benefits of exercise - with less stress to the heart! A hot tub increases the heart rate while lowering blood pressure, instead of raising it as does other forms of exercise.
A recent medical article titled "Mayo Clinic OK's Spas for Heart Patients" indicates that hot tubs and spas may not present as much of a risk to heart patients as previously thought. The report stated that relaxing in a spa might actually be less stressful to your heart than working out on an exercise bicycle.
The research, led by Dr. Thomas G. Allison of the world-renowned medical center, examined the body temperature and cardiovascular stress experienced by 15 patients at risk for heart disease both in hot water and on bicycles. The studies showed that exercise caused blood pressure to rise from an average of 121/73 to 170/84. By contrast, sitting in a spa made the blood pressure drop from an average of 117/77 to 106/61. The article also states that hot tub use will raise heart rates 25.7 beats per minute.
"When you get in a hot tub, your heart naturally beats faster," Dr. Allison explained, "and many heart disease patients want to know if the stress placed on the heart is too great."
*IMPORTANT NOTE* We strongly urge people who are at risk for heart disease to consult with your physician before entering a spa.
Help Reduce WeightAs unbelievable as it may sound, recent studies have proven that the regular use of hot tubs can aid in the reduction of weight, as well as diminish the appearance of cellulite. This stems from the fact that soaking in a hot tub simulates exercise. The hydrotherapy dilates the blood vessels, promoting better circulation as it relaxes the skin and muscles. It also raises the heart rate, while lowering blood pressure. This seems to indicate that soaking in a hot tub may be healthier for your heart than the traditional methods of exercise.
An article that appeared in the September 16, 1999 issue of the New England Journal of Medicine followed a group of subjects who were required to soak in a hot tub for thirty minutes a day, six days a week, for three weeks. Though this study was for diabetes research, the results were wide reaching. The patients' weight was reduced by an average of 3.75 pounds each! The subjects lost over one pound per week, just by soaking in a spa.
Regular use of hot tubs can also help to diminish the appearance of cellulite. The fatty deposits that typically gather on the hips, thighs, and buttocks of most women past their 30s can never be fully eliminated. The design of a woman's body naturally causes the skin to dimple out, whether she is overweight or thin. However, by improving circulation to the areas affected by cellulite, it has been proven that the appearance of the unsightly deposits can be reduced.
According to a variety of medical sources available on the Internet, the hydrotherapy that a hot tub provides stimulates the blood vessels, increasing circulation. It also tones the body tissue, reduces fluid retention, and relieves swelling. All of these benefits combined can result in the diminishment of the appearance of cellulite.
Soothe Arthritis & FibromyalgiaMany Canadians suffer from some form of arthritis pain. The good news for these victims is that there are safe and effective ways to both minimize the discomfort and prevent further damage.
According to a publication from The Arthritis Foundation, Spas, Pools, and Arthritis , "Regular sessions in your hot tub helps keep joints moving. It restores and preserves strength and flexibility, and also protects your joints from further damage. Exercise can also improve a person's coordination, endurance, and the ability to perform daily tasks, and can lead to an enhanced sense of self-esteem and accomplishment."
"A hot tub fulfills the need perfectly . . . providing the warmth, massage, and buoyancy that is so necessary to the well-being of arthritis sufferers. The buoyancy of the water supports and lessens stress on the joints and encourages freer movement. Water exercises may even act as a resistance to help build muscle strength."
Improve Athletic PerformanceBoth professional and "weekend" athletes can use their hot tubs to aid in repairing sore muscles and injuries. Neck and back pain, sports injuries, muscle pulls, spasms and soreness are often eased simply by a quick dip in your hot tub.
Before You Exercise. Soaking in a hot tub before exercising relaxes your body and loosens muscles, making exercise easier and reducing the risk of injury. A pre-exercise soak will also help to improve performance. In fact, some golfers swear it has actually reduced a couple strokes off their game.
After You Exercise. Soaking in a hot tub after exercising is a great way to wind down after the exercise and to relax your muscles. The hot, swirling water embraces you . . . massaging your neck, shoulders, arms, back, thighs, calves, and feet. But most importantly, hot tub use after you exercise will greatly reduce or even eliminate the stiffness typically felt the next day.
Your hot tub can also be used as preventive medicine. Water's therapeutic powers lie in its ability to alter the body's blood flow. According to an article in Tennis Magazine , "When you immerse yourself in the hot water of a whirlpool, the temperature of your skin and muscles rise, causing blood vessels to dilate and thus increases blood flow to the skin and muscles. Turn on the whirlpool jets and the pulsating water massages the skin, increasing blood flow even more. The result? Your skin and muscles loosen and relax from the increased blood circulation.
You can improve your athletic performance by using your hot tub both before and after you exercise.
*IMPORTANT NOTE* If an injury occurs, it is essential to apply ice to the swollen area first. Never get into a hot tub when you have swelling! Allow ample time for the swelling to reduce before soaking in your hot tub. The warm, circulating water will speed healing to any damaged tissue as well as bring much-needed nutrients to the problem area.
Relax and Reduce Stress The link between stress and illness should be of interest to anyone concerned with their health. We all have stress in our daily lives relating to work, family, and society. Mental tensions, frustrations, and insecurity are among the most damaging types of stress.
Affected by stress, the heart works harder, breathing becomes more rapid and shallow, and digestion slows. Nearly every process of the body is degraded. Researchers have estimated that 80% of disease is stress related. Since we usually can't avoid it, the key to dealing with stress is relieving it!
A soothing and relaxing soak in a hot tub can help counteract stress and its effects on the human body. It is the perfect antidote to a hectic and stressful lifestyle. The warm waters and soothing massage work to relieve anxiety and relax your tense muscles.
Numerous independent studies have proven that a warm water massage stimulates the release of endorphins, the body's natural "feel good" chemical. Your hot tub will enhance your sense of well being, and leave you feeling fresh, clean, and ready to tackle life's daily challenges.
Recommended Guidelines for Spa Use Persons suffering from heart disease, diabetes, high or low blood pressure, etc., should not enter a hot tub without medical consultation. In addition, use by the elderly and infants is not recommended without medical consultation.
Be aware that water attracts children. Prevent child drowning. NEVER let children use the hot tub unsupervised! Keep your hot tub covered and locked between periods of use. Don't leave an open hot tub unattended.
Never use a hot tub while under the influence of alcohol, anti-coagulants, antihistamines, vasoconstrictors, vasodilators, stimulants, hypnotics, narcotics, or tranquilizers. Spa heat accelerates the effects of alcohol and drugs and cause unconsciousness. Leave the hot tub immediately if you feel uncomfortable or drowsy.
Never use the hot tub alone.Observe a reasonable time limit when soaking in a hot tub, then shower, cool down, and if you wish, return for another brief stay. Long exposures may result in nausea, dizziness, or fainting.
Excessive water temperature is potentially dangerous. Always check the water temperature in the spa with an accurate thermometer - and your hands - before use. The recommended maximum temperature of the water is 104°F. Persons new to a spa will probably prefer 100°F as a beginning temperature.
Pregnant women should consult their physicians before use. It is important to note that the critical point in fetal development occurs in the first three months of pregnancy. Women of childbearing years are advised to observe caution in their use of a spa, in that they might be in the very earliest stages of pregnancy and not yet know it. Limit soaking use to ten minutes at a time.
