Swimming Pools and Hot Tubs with Diabetes: Safety, Risks, and Benefits
Comprehensive guide to safely enjoying swimming pools and hot tubs for people with diabetes, covering risks, benefits, and precautions.
For many, swimming pools and hot tubs are synonymous with relaxation, exercise, and social enjoyment. But if you are living with diabetes, you may wonder whether it’s safe to indulge in these aquatic activities. This comprehensive guide addresses the risks, benefits, and essential safety considerations for people with diabetes using swimming pools and hot tubs.
Understanding Diabetes and Water Activities
Diabetes can affect multiple systems in the body, impacting circulation, nerve function, and skin health. While swimming and soaking in hot tubs can offer physical and mental relaxation, water environments pose unique risks for those managing blood glucose levels and potential complications.
Can People with Diabetes Use Swimming Pools and Hot Tubs?
Yes, most people with diabetes can safely use swimming pools and hot tubs—but with extra precautions. Water-based activities can provide excellent cardiovascular benefits and muscle relaxation, but the combination of diabetes-related health concerns and specific risks of aquatic environments means safety should always come first.
Why Caution Is Needed: Main Risks for People with Diabetes
- Peripheral Neuropathy: Diabetes can lead to nerve damage, especially in feet and legs, resulting in reduced sensation. People with neuropathy may not feel extreme temperatures or injuries, raising the risk for burns or unnoticed wounds.
If soaking in water that’s too hot, the lack of sensation may prevent you from knowing when your skin is being damaged before it is too late. - Slow Wound Healing: Diabetes affects blood flow and can impair wound healing. Cuts or abrasions exposed to water, or that go unnoticed due to neuropathy, have higher risk of infection. Open wounds especially should never be exposed to public pools or hot tubs.
- Overheating and Heart Stress: Excessive heat from hot tubs can increase heart rate and body temperature, which is dangerous for people with heart problems or poor circulation commonly associated with diabetes.
- Blood Glucose Fluctuations: Heat and physical activity can influence blood glucose levels, sometimes leading to hypoglycemia (low blood sugar), especially in those taking insulin.
- Infection Risk: Pools and hot tubs can harbor bacteria. Diabetes makes people more susceptible to skin infections, especially if cuts, cracks, or ulcers are present.
Benefits of Safe Water Activities for People with Diabetes
- Improved Circulation: Warm water aids vasodilation—expanding blood vessels and boosting oxygen and nutrient delivery to extremities, potentially reducing risk for ulcers and aiding healing.
- Potential Lower Blood Glucose Levels: Regular use of hot tubs has been shown in small studies to reduce blood glucose for some people, especially those who find traditional exercise challenging. The mechanism: increased circulation and relaxation can aid glucose metabolism.
- Muscle Relaxation and Stress Relief: Gentle exercise and heat can relieve muscle pain, promote relaxation, and reduce overall stress levels—a key factor in effective diabetes management.
- Safe, Low-Impact Exercise: Swimming is accessible for people with joint pain, obesity, or mobility limitations, offering aerobic exercise without high impact on joints.
Are Hot Tubs Safe for People with Diabetes?
Hot tubs are not categorically unsafe for diabetes, but risks are elevated particularly for those with nerve damage, poor circulation, or other complications. Some studies have shown health improvements such as better blood glucose control, but these benefits must be balanced against the risk of burns, changes in insulin absorption, and increased risk of infection.

Considerations for Hot Tub Use:
- Check Water Temperature: Never exceed 104°F (40°C). For extra safety, keep water at or below 100°F (37.7°C) if you have known neuropathy or sensitivity issues.
- Limit Soaking Time: Avoid prolonged exposure. 15–20 minutes is generally considered safe for most adults, but always consult your healthcare provider.
- Test Water with Elbow: Because you may not feel heat in your feet due to neuropathy, use your elbow to test water temperature before entering.
- Do Not Use Alone: Always make sure someone else is present, especially when using a hot tub.
How Swimming Pools Can Be Beneficial
Swimming is often recommended for people with diabetes because it is a low-impact, aerobic exercise that helps control blood glucose, improves heart health, and enhances overall well-being.
- Cardiovascular Fitness: Swimming raises heart rate and improves fitness safely.
- Muscle Strength and Mobility: Water resistance helps build and tone muscles.
- Weight Management: Regular swimming can support healthy weight, improving insulin sensitivity.
Precautions for Safe Water Activity With Diabetes
Essential Steps Before Entering Pools or Hot Tubs
- Consult Your Healthcare Provider: Always speak with your doctor before starting any new activity, especially if you have complications like neuropathy, heart disease, or wounds.
- Check Your Blood Glucose: Test immediately before and after using a hot tub or swimming. If you use an insulin pump, ask your doctor whether to remove it before water exposure.
- Inspect Your Feet: Examine feet for cuts, sores, or blisters. Do not enter water if you have any open wounds.
- Keep Hot Tub Clean: Only use properly maintained, chlorinated pools and tubs. Private hot tubs present less risk than public facilities, which may harbor more bacteria.
- Stay Hydrated: Bring water and sip regularly to prevent dehydration, which can affect blood sugar.
- Monitor for Hypoglycemia: Be aware that heat can accelerate insulin absorption, causing blood glucose to drop faster. Always have a quick-acting carbohydrate nearby, such as glucose tablets, juice, or candy.
Special Advice for Those Using Insulin or with Neuropathy
- Insulin Pumps: Remove before swimming or hot tub use, as heat and water can interfere with device function and insulin delivery.
- Watch for Signs of Hypoglycemia: Symptoms such as sweating, shakiness, confusion, and dizziness may be harder to detect in warm environments. Monitor frequently.
- Extra Foot Care: Wash feet after soaking, dry thoroughly, and use powder or cornstarch to absorb moisture and reduce infection risk.
Frequently Asked Questions (FAQs)
Q: Is swimming recommended for people with diabetes?
A: Yes. Swimming is a safe, effective exercise that helps control blood sugar, enhances heart health, and is easy on joints. Always monitor glucose before and after swimming, and be cautious of foot injuries.
Q: Can hot tubs lower blood sugar in people with diabetes?
A: Sometimes. Small studies indicate regular hot tub use can help lower blood sugar, particularly in people unable to exercise conventionally. However, the risk of hypoglycemia and burns is increased, so always consult your provider.
Q: What is the safest water temperature for people with diabetes?
A: Keep hot tub water temperature between 100°F and 104°F (37°C to 40°C) and always use a thermometer if you have neuropathy or poor sensation.
Q: Should I use swimming pools and hot tubs if I have open wounds?
A: No. Open wounds increase infection risk, especially for people with diabetes. Wait for wounds to fully heal before using communal or private pools and hot tubs.
Q: How can I protect myself from infections in pools and hot tubs?
- Use well-maintained, chlorinated pools or tubs
- Shower before entering
- Do not share towels, shoes, or personal items
- Inspect feet and skin for any breaks, sores, or ulcers
