How Long Should You Stay in a Hot Tub? A Complete Safety & Relaxation Guide

Hot tubs are one of the best ways to relax, ease muscle tension, and improve overall wellbeing. Whether you use your spa to unwind after work or as part of a wellness routine, one question is asked more than any other: how long should you stay in a hot tub?

While soaking for too little time may limit the benefits, staying in a hot tub for too long can increase the risk of dehydration, overheating, and dizziness. Understanding the ideal hot tub session length, how temperature affects safety, and who should take extra care allows you to enjoy your spa responsibly.

In this guide, CenturaHeat explains the recommended time to spend in a hot tub, how factors like temperature and health impact your soak, and essential safety tips for adults, children, and elderly users.

What Is the Recommended Time to Stay in a Hot Tub?

For most healthy adults, experts agree that the ideal hot tub session lasts between 15 and 30 minutes.

Health guidance suggests that 15–20 minutes is optimal when the water temperature is set between 38°C and 40°C (100–104°F). This timeframe provides muscle relaxation, stress relief, and circulation benefits without placing unnecessary strain on the body.

Staying longer than 30 minutes may increase the risk of:

• Overheating
• Dehydration
• Lightheadedness or nausea

If you’re new to hot tub use, start with shorter sessions and gradually build up as your body adapts.

How Hot Tub Temperature Affects Safe Soaking Time

Water temperature plays a major role in determining how long you can stay in a hot tub safely. The hotter the water, the shorter your recommended session.

Hot Tub Temperature Guidelines

• 37–38°C (98–100°F): Up to 30 minutes for healthy adults
• 39–40°C (102–104°F): Limit sessions to 15–20 minutes
• Above 40°C (104°F): Not recommended due to increased heat stress risk

Keeping your spa within a safe temperature range allows you to enjoy longer, more comfortable sessions. Always check your hot tub settings before entering.

Who Should Limit Time in a Hot Tub?

Not everyone should follow the same hot tub session length. Certain groups need to take extra precautions.

Children

Children heat up faster due to their smaller body size. They should:

• Spend no more than 5–10 minutes in the hot tub
• Use lower temperatures (below 38°C)
• Always be supervised

Elderly Users

Older adults may be more vulnerable to dehydration and dizziness. It’s best to:

• Limit sessions to 10–15 minutes
• Take frequent breaks
• Consult a GP if unsure

People With Health Conditions

Those who are pregnant or have heart conditions, high blood pressure, or diabetes should seek medical advice before hot tub use. Shorter sessions or avoidance may be recommended.
