A sauna session should be restorative, not risky. This guide covers everything you need to know to use your Gravity sauna safely and get the most from every session.
## Who Should Exercise Caution
Saunas are safe for the vast majority of healthy adults. However, the following groups should consult a medical professional before use:
- Pregnant women
- Individuals with cardiovascular conditions (hypertension, heart disease, arrhythmia)
- Those with active inflammatory skin conditions
- Individuals taking medications that affect thermoregulation or blood pressure
- Children under 12 (who should always be accompanied by an adult)
- Those who have consumed alcohol
## Hydration is Essential
The most common cause of sauna-related adverse events is dehydration. During a 30-minute session, a typical adult loses 0.5–1 litre of fluid through perspiration. Drink 500ml of water before your session, and continue hydrating afterwards.
## Session Length Guidelines
**Beginners**: Start with 10–15 minute sessions at the lower end of the temperature range. Allow your body to acclimatise over several sessions before extending duration or increasing temperature.
**Regular users**: Sessions of 20–40 minutes are well tolerated by most. Listen to your body — dizziness, nausea, or heart palpitations are signals to exit immediately and cool down.
**Maximum recommended session**: 45 minutes. If you wish to extend your sauna time, take a break, cool down, rehydrate, and re-enter.
## During Your Session
- Sit on a towel — both for hygiene and to prevent direct contact with heated wood
- If you feel dizzy or unwell at any point, exit calmly and cool down
- Never sleep in the sauna
- Keep the door unlocked — always ensure someone knows you are using the sauna
## After Your Session
Cool down gradually. A cool shower is ideal; avoid immediately entering very cold water or cold air if you are a beginner, as this can cause a sudden cardiovascular response. Rest for 10–15 minutes before resuming normal activity.
## Maintenance and Hygiene
- Wipe down benches after each use with a damp cloth
- Leave the door ajar after use to allow the cabin to air and dry
- Clean the interior monthly with a mild natural wood cleaner — avoid chemical cleaners that may leave toxic residues when heated
- Inspect the heater and electrical connections periodically for any signs of wear

This depends on the nature of your condition and your current medication. Please consult your GP before using a sauna if you have a diagnosis of hypertension or any cardiovascular condition.
Is it safe to use a sauna every day?
Daily sauna use is well tolerated by most healthy adults, and research suggests that frequent use compounds the health benefits. Ensure you are adequately hydrated and take rest days if you notice signs of fatigue.

A towel is sufficient and recommended for hygienic reasons. Avoid synthetic fabrics, jewellery, and any items that may become uncomfortably hot or that you are concerned about exposing to heat.
