Diabetes and Hot Tubs: Safety Tips and Benefits
Living with diabetes often means making thoughtful lifestyle choices that help you stay balanced, both physically and emotionally. The words “diabetes” and “hot tubs” may not typically be used in the same sentence, but for many diabetics, hydrotherapy can offer a range of health benefits when practiced safely. From improved circulation to stress relief, spas can be a great way to complement a diabetic-friendly wellness routine.
With that being said, like all therapies, it’s also important to understand the potential risks and how to safely enjoy a soak. In this blog, we’ll explore the specific benefits of hot tubs for people with diabetes, while also covering important safety tips to ensure every session supports your well-being.
Understanding Diabetes and Its Challenges
Before we dive into the specifics of hot tubs, let’s briefly review how diabetes affects the body. There are two main types of diabetes:
- Type 1 Diabetes: An autoimmune condition where the pancreas produces little or no insulin.
- Type 2 Diabetes: A metabolic condition where the body either resists insulin or doesn’t produce enough.
Both types result in high blood glucose levels, which can lead to long-term complications like:
- Poor circulation
- Nerve damage (neuropathy)
- Increased risk of infections
- Muscle stiffness
- Stress and fatigue
Hot tubs, when used appropriately, may help alleviate some of these symptoms and support overall wellness.
Health Benefits of Hot Tubs for Diabetics
1. Improved Circulation
Hot water promotes vasodilation, which is the widening of blood vessels. This improves circulation throughout the body—something that’s often compromised in individuals with diabetes. Better circulation also helps deliver oxygen and nutrients to the extremities, reducing the risk of foot ulcers and other complications potentially associated with diabetic neuropathy.
Tip: Keep your water temperature between 100°F and 104°F (37°C to 40°C) to encourage safe circulation improvements without overheating.
2. Lower Blood Sugar Levels
Some studies have shown that regular hot tub use can lower blood glucose levels. In a 1999 study published in the New England Journal of Medicine, patients with Type 2 diabetes who soaked for 30 minutes a day, six days a week, experienced a significant reduction in blood glucose levels—up to 13% to be more specific.
While it’s not a replacement for insulin or medication, hydrotherapy may support metabolic function, particularly for people with mobility challenges who find exercise difficult.
3. Stress Reduction
Chronic stress can elevate cortisol levels, which in turn can lead to insulin resistance and unstable blood sugar levels. Hot tubs are well-known for their relaxing effects—warm water, gentle massage jets, and a quiet environment all contribute to lowering stress hormones.
Over time, regular soaks can become a powerful part of your mental and emotional diabetes management plan.
4. Muscle Relaxation and Pain Relief
People with diabetes often suffer from muscle stiffness, joint pain, or peripheral neuropathy (nerve pain in the hands and feet). Fortunately, a hot tub’s buoyancy reduces pressure on joints while the warm water relaxes tense muscles. Targeted jet action can also ease discomfort in the back, legs, and feet, helping diabetics move more freely and sleep more soundly.
5. Better Sleep Quality
Sleep disturbances are common in people managing diabetes, and poor sleep can negatively affect blood sugar control. Soaking in a hot tub 90 minutes before bedtime can help raise core body temperature and induce a natural cooldown effect, which signals to the body that it’s time to rest. This can result in deeper, more restorative sleep, potentially improving insulin sensitivity over time.
Safety Tips for Diabetes and Hot Tubs
Despite the many benefits of hot tub use, diabetics need to take some specific precautions when soaking in the spa. Here’s how to make sure your soak is safe and beneficial:
1. Monitor Blood Sugar Levels Before and After
Hot water can increase insulin sensitivity, which may cause hypoglycemia (low blood sugar), especially in those taking insulin or glucose-lowering medications. Always check your blood sugar before entering the tub and again afterward. Have a snack or glucose tablet on hand in case your levels drop.
Also, aim to soak when your blood sugar is stable, not at a peak or low point.

2. Limit Soak Time
Stick to 15–20 minutes per session to prevent overheating or dehydration. Overexposure to high temperatures can lower blood pressure and cause dizziness, fainting, or heart palpitations, which is especially risky if you already have cardiovascular complications.
3. Inspect Feet and Skin Regularly
Diabetics can be more prone to infections and slow wound healing, especially in the feet. Before and after hot tub use, check for cuts, blisters, or dry skin. Never use a hot tub if you have open sores, ulcers, or active infections.
4. Stay Hydrated
Even though you’re surrounded by water, soaking can lead to dehydration, which can be especially dangerous for diabetics. Drink a glass of water before and after your soak, and avoid alcohol or caffeine, which can dehydrate you further.
5. Avoid Soaking Alone
If you're prone to blood sugar swings or have diabetic complications like neuropathy or heart disease, always let someone know you’re using the hot tub or have someone nearby. In case of dizziness, a fall, or a blood sugar emergency, make sure help is within reach.
Additional Considerations for Diabetes and Hot Tubs
Talk to Your Doctor First
Everyone’s diabetes journey is different. Before adding hot tub therapy to your routine, check with your healthcare provider, especially if you:
- Have cardiovascular disease
- Take insulin or blood pressure medication
- Have diabetic neuropathy
- Have kidney problems
- Are pregnant
A simple conversation could help you avoid complications and develop a smart soaking plan tailored to your needs.
Choose the Right Hot Tub
If you’re shopping for a hot tub with diabetes in mind, here are a few features to prioritize:
- Easy Entry/Exit: Steps or handrails for stability.
- Adjustable Jets: For gentle massage and foot therapy.
- Temperature Control: Precision settings to avoid overheating.
- Efficient Water Care: Brands like Sundance® Spas and Jacuzzi® offer advanced filtration and water care systems that reduce bacteria, important for people with higher infection risk.
Can Hot Tubs Replace Exercise?
Not quite—but they can help support it. If your mobility is limited due to diabetic complications or weight issues, hot tubs offer a low-impact way to loosen up muscles and encourage movement. Some users find that hot tub sessions help them stretch, improve range of motion, and prepare the body for physical activity like walking or gentle yoga.
Over time, this increased flexibility and reduced pain may make it easier to engage in regular exercise, which is critical for long-term diabetes management. You can learn more about our variety of fitness-focused swim spas here.
When to Avoid Hot Tubs
Hot tubs are not for everyone. You should avoid hot tubs entirely if:
- You have uncontrolled high blood pressure
- You’re experiencing dizziness or fatigue
- You have open wounds, sores, or infections
- You’ve consumed alcohol or drugs that impair your response
- Your blood sugar is too low or extremely high
Also, never sleep in a hot tub, even if it feels relaxing. Falling asleep while soaking poses a serious risk of overheating, dehydration, or accidental drowning.
Soak Smart for Better Health
When used safely and mindfully, hot tubs can be a wonderful addition to a diabetic’s wellness plan. From better circulation and stress relief to muscle relaxation and improved sleep, the benefits of hydrotherapy are both physical and mental. With just a few smart precautions—like checking blood sugar, staying hydrated, and keeping sessions short—most people with diabetes can enjoy the healing power of warm water.
As always, talk to your doctor before starting any new wellness routine. But once you get the green light, feel free to sink into the comfort of a well-designed hot tub and let it support your journey toward better health, one soak at a time.
