According to Bruce Becker, M.D., immersing yourself in water in general up to your neck gives you a cardiac workout. This is because water puts more pressure on your body which increases your cardiac volume. In other words, when you’re soaking in water, your heart works harder and that helps it stay healthy.
Hot water promotes relaxation which helps you sleep. This is easy enough to explain. When you put your tense body is a tub of hot water, the heat raises your body temperature and relaxes your muscles. This makes you tired and relaxed which can help you sleep better. However, you should not attempt to fall asleep in a spa bath. That’s a terrible idea.
As we just explained, hot water in general helps relax your body. This can also alleviate aches and pains associated with athletic injuries like muscle pulls or even arthritis. If you’re in pain and it’s not a broken bone, a good soak will probably help you feel better.
A small study that was conducted has shown that people with diabetes who take regular spa baths can reduce their blood sugar and blood glucose levels. It also showed that taking a spa bath for 30 minutes, six days a week lost four pounds in a month without making a single change to their diet or exercise. It’s not the next big diet but every little bit helps!
