Proper sauna use is important; just like we warm up and cool down our bodies when we exercise, there are some basic steps to follow to ensure you gain maximum benefits of using a sauna.

Before Sauna Use:

Drink a minimum of 8 oz. of water to prepare your body for an increase in core body temperature.
Prep your sauna: Pre-heat your sauna for 15 minutes. Your sauna will heat up approximately one degree per minute, depending on room temperature.
Lay down towels on the bench to absorb sweat. It’s also nice to have an extra around to wipe your face during sessions.

During Sauna Use:

Watch your time: Make sure to adjust your session length in accordance to your body’s needs. If you are just beginning with regular sauna use. We recommend beginning with 10-15 minute sessions at 100°F every other day. Gradually increase toward 40 minute daily sessions in the optimal temperature range. Always listen to your body and adjust based on what it’s telling you.
Stick with it for long-term benefits: Just as with exercise or eating healthy, sauna use takes time and consistency to see results. You may not even sweat the first few times you use your sauna, but know that sweating (and the detox that comes with it) will increase over time, leaving you feeling rejuvenated and healthy.

After Sauna Use:

Rehydrate with at least 24 oz. of water or electrolyte drink.
Dry off and cool down naturally, or with a refreshing shower.
Keep it clean: Using towels on the bench to absorb sweat and excess moisture will help keep your sauna clean during regular use. Clean the wood and glass in your sauna every six months with our Natural Sauna Cleaning Kit.

Most people partake in a 30-45 minute session, 3-4 times a week, but it is safe to use every day and at whatever heat suits you best.

HEAL ™ Sauna with unique Rapid Internal Heating System™. Set to the desired temperature and allow the sauna to warm up for 10-15 minutes.

HEAL ™ Sauna Cleaner is made specifically for use with your sauna. At least every six months, dampen a cloth with Healthlighten All Natural Wood Cleaner. Clean glass door and windows with Healthlighten All Natural Glass Cleaner. You may dust the outside of the sauna with a dry dust cloth. Do not use chemical cleaners on your sauna. Light sandpaper can be used to treat stains on the inside of the sauna. Healthlighten Natural Sauna Cleaning Kit can be purchased at the Healthlighten Online Store or through your local dealer.

We offer a variety of shipping options, including curbside delivery (free), white-glove service (shipping to customer-specified location), and installation. Different options have different prices. Customers can choose their shipping method on the checkout page.

We unpack the sauna and place it in a wooden box. The wooden box is reinforced and anti-fall. We will compensate for any damage during transportation free of charge.

The core body temperature of children rises much faster than adults. This occurs due to a higher metabolic rate per body mass, limited circulatory adaptation to increased cardiac demands and the inability to regulate body temperature by sweating. When using your sauna with a child, operate at a lower temperature and for no more than 15 minutes at a time. A general rule of thumb is 1 minute inside your sauna per year of age for the child, but always accompanied by an adult. And remember to keep you and your children hydrated, even if you don’t see them sweating.

The sauna runs on the same wattage as a blow dryer and will cost little to run monthly: typically 15 to 35 cents per hour. This varies with the model and local utility cost. Your utility company can help you understand a more exact per hour cost if needed.

Just as you would not leave your cell phone in your car on a hot day, we do not recommend taking cells phones, Apple watches or other electronics in the sauna. The electronics that are built into the sauna are designed for a heated environment.

No. Because HEAL™ saunas have double-wall re-enforcement, thicker wood than the industry standard and Magne-Seal assembly to create a better heat seal, when your sauna is on you will still not feel heat coming off the exterior walls.
