• Hydrate before and after, skip alcohol, and build up session length slowly.
• Keep cold plunges short, breathe slowly, and never plunge alone.
• Wear eye protection for red light and tell us about light-sensitizing medicines.
• Our mild hyperbaric sessions are wellness sessions, not hospital HBOT.

Why heat, cold and light?

Sauna, cold plunge, red light and hyperbaric sessions have become popular recovery tools, and Minnesota has a long sauna tradition. Used thoughtfully, they can be a relaxing part of your routine. Research is growing but still mixed on many claims, so this guide sticks to what's known and how to use each one safely.

The golden rules

• Hydrate before and after. Drink a glass or two of water before heat sessions and again afterward. Sweat is mostly water and salt, and you can lose a fair amount.
• Start low, go slow. Begin with shorter sessions and build up over several visits.
• Skip alcohol before and during heat or cold sessions. It raises the risk of dehydration, low blood pressure and fainting.
• Eat lightly. A big meal right before can leave you lightheaded.
• Listen to your body. Dizziness, nausea, headache, chest pain or a pounding heart mean stop, cool down and tell a team member.
• Stand up slowly after heat, since blood pressure can dip when you rise.

Infrared sauna

Our far infrared sauna is tuned to 4.4 to 14.4 microns, wavelengths that warm your body directly, so the air feels milder than a traditional sauna. Many guests describe it as deeply relaxing, and heat may help ease minor muscle aches. Studies of regular sauna bathing, mostly traditional Finnish saunas, suggest possible benefits for relaxation and heart health, though more research is needed (Harvard Health, Cleveland Clinic).

• On your first visits, try about 10 to 15 minutes, then build up if you feel well.
• Wear light clothing or a swimsuit and sit on a towel.
• Any weight you lose in a sauna is water, which returns when you rehydrate.

More on our Far Infrared Sauna page.

Cold plunge and contrast therapy

Cold water sets off a "cold shock" response: fast breathing and a jump in heart rate and blood pressure during the first minute. That's why slow, steady breathing and short dips matter. Cleveland Clinic notes possible benefits for post-workout soreness and feeling alert, along with real risks for people with heart conditions.

• Start with 30 seconds to a minute or two, and keep your head and neck above water.
• Never plunge alone. Get out if you feel numb, shiver hard or feel dizzy.
• If building muscle is your goal, Mayo Clinic notes that cold immersion right after strength training may blunt some gains. Consider spacing them apart or plunging on rest days.

Contrast therapy alternates sauna heat with a cold tub. A simple routine: 10 to 15 minutes of heat, 1 to 2 minutes of cold, a few minutes of rest, repeated for 2 to 3 rounds. Many people end on cold to feel energized, or on warmth to wind down. See our Contrast Therapy page and membership options.

Red light therapy

Red light therapy (also called photobiomodulation) uses low-level red and near-infrared light. It doesn't burn or tan your skin. Cleveland Clinic describes the research as promising but still limited, mostly around skin appearance. Safety basics:

• Wear the eye protection provided, and don't stare into the lights.
• Tell us if you take anything that makes you sensitive to light (some antibiotics, acne medicines and St. John's wort, for example), if you have a history of skin cancer or a light-sensitive condition, or if you're pregnant.
• Come with clean skin, free of heavy lotions or makeup.
• More isn't better. Follow the session times we recommend.

More on our Red Light Therapy page.

Mild hyperbaric sessions

Our hyperbaric sessions use a soft, mild chamber that's gently pressurized while you rest for about 90 minutes. This is a wellness session, not hospital hyperbaric oxygen therapy (HBOT). The FDA has cleared medical HBOT only for specific conditions, delivered under medical care, and warns consumers about claims beyond those uses. Our chamber is the only wheelchair-accessible soft hyperbaric chamber in the Twin Cities.

• Your ears will feel pressure, like on an airplane. Swallow, yawn or gently pinch your nose and blow to equalize.
• Wear comfortable clothing and follow our team's guidance on what to bring inside.
• We'll screen you for recent ear or sinus surgery or infection, pregnancy, certain lung conditions and claustrophobia.

Always check with your physician to see if a service is right for you. More on our Hyperbaric page.

Who should check with a doctor first

Talk with your physician before heat, cold, light or pressure sessions if you:

• Are pregnant or trying to become pregnant
• Have heart disease, an irregular heartbeat, a past heart attack or stroke, or high or low blood pressure
• Have Raynaud's or strong cold sensitivity (for cold plunges)
• Have a pacemaker or other implanted device
• Take medicines that affect sweating, heart rate, blood pressure or light sensitivity, such as diuretics or beta-blockers
• Have trouble sensing heat or cold, for example from nerve changes in your feet
• Have a fever, an active infection, recent surgery or a recent injury with swelling

• Your nervous system has a stress branch and a rest branch; both matter.
• Slow breathing with a longer exhale is a free, anytime way to feel calmer.
• Sound baths are a relaxation practice, with early but limited research.
• Steady sleep times, morning light and a dark, cool room support better sleep.

Your nervous system, in plain words

Your autonomic nervous system runs the things you don't think about: heartbeat, breathing, digestion and sweating. It has two main branches that work like a gas pedal and a brake.

• Sympathetic ("fight or flight"): speeds up your heart and breathing and sends energy to your muscles when you face a challenge.
• Parasympathetic ("rest and digest"): slows your heart, supports digestion and helps you recover. The vagus nerve, which runs from your brain down to your belly, is a major part of this calming branch.

Both are healthy and necessary. Trouble starts when the gas pedal stays pressed for weeks or months with little time on the brake.

Signs you may be running on stress

• Trouble falling asleep or staying asleep
• Feeling "wired but tired"
• Tight shoulders, a clenched jaw or frequent headaches
• Upset stomach or changes in appetite
• Irritability, racing thoughts or trouble focusing

These signs can have many causes, including medical ones, so mention them to your doctor if they stick around.

Small daily resets add up: a short walk outside, a few slow breaths between tasks, gentle stretching, time with people you trust, and breaks from news and scrolling. Regular physical activity is one of the most dependable ways to ease everyday stress.

Breathwork you can do anywhere

Breathing is the one part of your autonomic nervous system you can easily steer on purpose. Harvard Health notes that slow, deep breathing can help quiet the stress response. Try one of these for 2 to 5 minutes. Kristin also shares simple breathing tools in a short video on our YouTube channel.

1. Belly breathing: Place one hand on your chest and one on your belly. Breathe in through your nose so your belly rises more than your chest. Breathe out slowly through pursed lips.
2. Longer exhale: Breathe in for a count of 4, then out for a count of 6 to 8. Many people find a longer exhale especially calming.
3. Box breathing: Breathe in for 4, hold for 4, breathe out for 4, hold for 4. Repeat.

If you feel dizzy or lightheaded, go back to normal breathing. If you're pregnant or have a heart or lung condition, keep breath holds short or skip them.

Sound baths and other calming practices

In a sound bath, you lie down comfortably while a practitioner plays instruments like singing bowls and gongs. Many people describe feeling calm, drowsy or deeply relaxed, and falling asleep is common. Cleveland Clinic notes the research is early and mostly small studies, so we offer sound baths as a relaxation practice, not a treatment.

We offer a 30-minute introductory sound bath, 60-minute private sessions, and couples and group sound baths. See our Sound Therapy page. If you have epilepsy, tinnitus, sound sensitivity or a serious mental-health condition, or you're pregnant, check with your provider first and let us know.

Other gentle options include craniosacral therapy, a light-touch, hands-on relaxation technique, and energy healing. These are complementary practices, not substitutes for medical or mental-health care. Our Wednesday seminars and peer support groups, listed on the events calendar, are another way to practice calm with others. Support groups offer peer support, not therapy.

Sleep habits that help

Most adults need at least 7 hours of sleep a night, according to the CDC. These habits can help:

• Keep a steady schedule, even on weekends.
• Get daylight in the morning and dim the lights in the evening to support your body clock.
• Make your bedroom cool, dark and quiet.
• Put screens away 30 to 60 minutes before bed.
• Limit caffeine after midday, and avoid alcohol and big meals close to bedtime. Alcohol may make you drowsy at first, but it tends to disrupt sleep later in the night.
• Move during the day, but finish hard workouts a few hours before bed.
• Build a wind-down routine: a warm shower, light stretching or a few minutes of slow breathing.
• Can't sleep after about 20 minutes? Get up, do something quiet in dim light, and go back to bed when you feel sleepy.

When to get professional help

Talk with your doctor if:

• Trouble sleeping lasts more than a few weeks or affects your days
• You snore loudly, gasp or stop breathing during sleep, or feel very sleepy during the day, which can be signs of sleep apnea
• Stress, worry or low mood make it hard to work, connect with others or enjoy life

If you're in crisis or thinking about harming yourself, call or text 988 (the Suicide & Crisis Lifeline), or call 911.

• The lymphatic system balances fluid and carries infection-fighting white blood cells.
• Lymph has no pump; muscle movement and deep breathing keep it flowing.
• Lymphatic drainage uses very light, slow strokes, not deep pressure.
• Sudden swelling in one limb, or swelling after cancer care, needs a doctor.

What the lymphatic system does

Your lymphatic system is a network of vessels, lymph nodes and organs such as the spleen, thymus and tonsils. Each day, some fluid seeps out of tiny blood vessels into your tissues. The lymphatic system collects this extra fluid, now called lymph, filters it through lymph nodes and returns it to your bloodstream.

It has three big jobs:

• Keeping fluid levels balanced so tissues don't swell
• Carrying infection-fighting white blood cells and filtering germs in the lymph nodes
• Absorbing fats from your digestive tract

Lymph nodes are the small, bean-shaped glands you can sometimes feel in your neck, armpits and groin. They often swell a bit when your body is fighting a cold or other infection, and they usually settle back down within a week or two.

How lymph moves

Unlike blood, lymph has no heart to pump it. It moves mainly through:

• Muscle movement, which squeezes nearby lymph vessels
• Breathing, as deep breaths change pressure in your chest and belly
• Gentle squeezing of the vessel walls, with one-way valves keeping lymph headed toward your heart

That's why long stretches of sitting, like a flight or a long drive, can leave your ankles puffy, and why a short walk often helps.

Everyday habits that support lymph flow

• Move often. Walking, swimming, yoga or a few minutes of movement every hour you sit. Try ankle pumps and calf raises at your desk.
• Breathe deeply. A few minutes of slow belly breathing, a few times a day.
• Stay hydrated. Lymph is mostly water, and drinking enough supports normal fluid balance.
• Put your feet up at the end of a long day on your feet.
• Choose comfortable clothing that doesn't dig in at the waist, legs or ankles.

Manual lymphatic drainage and self-care

Lymphatic drainage massage uses very light, slow, rhythmic strokes that gently stretch the skin in the direction lymph flows. It's much gentler than a deep-tissue massage. In medical settings, certified lymphedema therapists use it as part of care for lymphedema. In a wellness setting, many people enjoy it for relaxation and a feeling of lightness, especially in the face and neck.

You can try gentle self-care at home, too. Cleveland Clinic offers a step-by-step self-massage guide, and Kristin demonstrates a gentle neck technique on our YouTube channel. Keep pressure light: you're moving skin, not muscle.

Endermologie and Gua Sha

Endermologie uses a device with motorized rollers and gentle suction that lift and roll the skin while you wear a special body stocking. Sessions are 60 minutes, and many guests describe the feeling as a deep, rolling massage. It's designed to temporarily improve the look and feel of skin, including the appearance of cellulite, and many guests find it relaxing. Results vary and aren't permanent, so regular sessions are usually part of the plan. See our Endermologie page.

Our 45-minute Endermologie Gua Sha Facial combines gentle lymphatic-style facial techniques with gua sha, a traditional practice of gliding a smooth stone tool across the skin. Many guests say their face looks refreshed afterward. Learn more on our Holistic Facials page.

Power Plate and whole-body vibration

The Power Plate is a whole-body vibration platform. As it vibrates, your muscles make many small, quick contractions while you stand, squat or stretch on it. Since muscle movement helps lymph move, many people use it as a short, low-impact way to get their body moving. Sessions are 20 minutes.

Mayo Clinic notes that whole-body vibration may offer some benefits, such as for muscle strength and balance, but research is mixed and it doesn't replace regular exercise. Skip it, or ask your doctor first, if you're pregnant or have had recent surgery, joint implants, a pacemaker, a history of blood clots, epilepsy or retinal problems. See the Power Plate FAQ.

Who should check with a doctor first

Lymphatic drainage, Endermologie and vibration are gentle, but they aren't right for everyone. Talk to your doctor first, and let us know, if you have:

• Congestive heart failure or another heart condition
• A current or past blood clot (deep vein thrombosis)
• An active infection, fever or skin infection such as cellulitis
• Kidney disease
• Current or recent cancer treatment
• Pregnancy
• Lymphedema (work with your doctor and a certified lymphedema therapist)

See a doctor promptly for sudden swelling in one leg or arm, especially with pain, warmth or redness, which can signal a blood clot; swelling after cancer surgery or treatment; or a lymph node that stays swollen, feels hard or keeps growing for more than two weeks. Swelling with shortness of breath needs emergency care.

• Complementary care works alongside medical care, never in place of it.

• In Minnesota, unlicensed practitioners must give you a written Client Bill of Rights.
• Tell all your health care providers about the wellness services and supplements you use.

Complementary, alternative, integrative: what's the difference?

The National Center for Complementary and Integrative Health (NCCIH) uses three terms:

• Complementary: a non-mainstream practice used together with conventional medicine.
• Alternative: a non-mainstream practice used instead of conventional medicine.
• Integrative: conventional and complementary care brought together in a coordinated way.

Healing Within offers complementary wellness services. We see them as partners to your medical care, never replacements. Please don't stop or delay medical care you need because of a wellness service.

How to read the research

Not all studies carry the same weight. Here are common study types, roughly from earliest clues to strongest evidence (NCCIH's guide to research types goes deeper):

1. Lab and animal studies test ideas in cells or animals. They offer early clues, but results often don't carry over to people.
2. Case reports and case series describe what happened to one person or a few people, with no comparison group.
3. Observational studies follow groups of people over time. They can show links, but not cause and effect.
4. Pilot or feasibility studies are small first tests in people, often to see whether a bigger study is practical.
5. Randomized controlled trials (RCTs) randomly assign people to the practice or a comparison, like a placebo or usual care. Well-run RCTs are the best way to test whether something works.
6. Systematic reviews and meta-analyses pull together all the good studies on a question. They carry the most weight.

Why small and pilot studies are only a starting point

Small studies can be exciting, but they're easy to over-read. With only a handful of people, a result can happen by chance. Without a comparison group, it's hard to tell the effect of a practice apart from the placebo effect, the extra attention, or simply time passing. Many promising early findings shrink or disappear in larger, better-controlled trials.

Our own reading list on energy medicine includes pilot studies, case series and lab research. We share it because these are interesting starting points, not proof. When you read any study, ask: How many people were in it? Was there a comparison group? Who paid for it? Has anyone repeated the results? NCCIH's free Know the Science series is a great place to build these skills.

Questions to ask any practitioner

• What training or certification do you have, and from where?
• Are you licensed in Minnesota? If not, may I see your Client Bill of Rights?
• What happens during a session, and what might I feel?
• What does the research say, and what are its limits?
• Are there risks or side effects? Is it safe with my health conditions and medicines?
• How many sessions do you suggest, and what will it cost in total?
• How will we know whether it's helping?
• Are you comfortable working alongside my doctor?

A good practitioner welcomes these questions. Be cautious of anyone who promises a cure, tells you to stop medical treatment, or pressures you to decide on the spot. NCCIH's checklist for considering a complementary approach is another helpful resource.

Your rights in Minnesota

Minnesota allows unlicensed complementary and alternative health care practitioners to practice, with protections for clients under Minnesota Statutes section 146A.11. Before services begin, an unlicensed practitioner must give you a written Client Bill of Rights, post a copy in the office, and have you sign that you received it. Among other things, it must tell you:

• The practitioner's name, business address, phone number and qualifications, along with a statement that Minnesota has not adopted education or training standards for unlicensed practitioners
• That an unlicensed practitioner may not diagnose or advise you to stop prescribed treatment, and that you may see a licensed provider at any time
• A plain-language summary of their approach, their fees and how they bill
• Your right to complete information about recommended services, to confidentiality, and to see your records
• Your right to courteous treatment free from abuse, to refuse services, and to speak up without retaliation
• How to file a complaint with the state office that oversees unlicensed practitioners

Our practitioners provide this document before services. You can read the full text on the Minnesota Department of Health website.

Keep your doctor in the loop

NCCIH encourages everyone to tell all their health care providers about any complementary approaches they use. It keeps your care safe and coordinated.

• Bring a written list of supplements, herbs and wellness services to appointments.
• Mention services that involve heat, pressure, water or diet changes, which can matter for heart, blood pressure, kidney or diabetes care.
• Ask before starting something new if you're pregnant, nursing, managing a chronic condition or preparing for surgery.
• Let your wellness practitioner know about medical changes, too.

HSA basics

A Health Savings Account (HSA) lets people with a qualifying high-deductible health plan set aside tax-advantaged money for qualified medical expenses. Healing Within accepts HSA payments. A few things to know:

• The IRS defines what counts as a qualified medical expense (IRS Publication 502). Many general wellness services don't qualify on their own.
• Some services may qualify when a doctor recommends them for a specific medical condition, often documented in a Letter of Medical Necessity.
• You're responsible for making sure HSA spending follows IRS rules, and your HSA administrator may ask for receipts or documentation.
• Keep receipts and any doctor's letters with your tax records.

Questions? Ask your HSA administrator or a tax advisor. IRS Publication 969 covers HSA rules in detail. For membership questions, see our Memberships page.
