Why You Should Use the Infrared Sauna After Your Workout — and How It Supports Longevity

You’ve just finished your workout. Your muscles are warm, your heart rate is up, and your body is buzzing with endorphins. This is the perfect time to step into the soothing warmth of an infrared sauna.


Far from being just a post-workout luxury, the infrared sauna is a powerful recovery tool with benefits that go beyond relaxation. It can help your muscles recover faster, enhance your performance, and even support your long-term health and longevity.

1. Faster Muscle Recovery

After exercise, your muscles have tiny microtears (that’s how they get stronger). The infrared sauna’s gentle heat penetrates deep into muscle tissue, increasing blood flow and delivering oxygen and nutrients exactly where they’re needed for repair.


Benefits:

  • Reduces post-workout soreness
  • Speeds up muscle healing
  • Helps you get back to your workouts sooner

 

2. Reduced Inflammation and Joint Pain

Inflammation is your body’s natural response to exercise, but too much can slow recovery and cause stiffness. Infrared heat helps calm inflammation, making it easier to move and stretch without discomfort the next day.

This is especially helpful if you’re doing Pilates, weight training, or high-intensity workouts that challenge your joints.

 

3. Detoxification for a Lighter, Energized Feel

Sweating in an infrared sauna helps your body release toxins and metabolic waste built up during exercise. This isn’t just about “detox” as a buzzword; it’s about helping your body’s natural cleansing systems function optimally, which supports overall energy levels and vitality.

 

4. Stress Reduction and Nervous System Recovery

Exercise is a good kind of stress, but it still activates your body’s “fight or flight” response. Stepping into the infrared sauna helps switch you into “rest and digest” mode by lowering cortisol (your stress hormone) and increasing relaxation hormones like serotonin.


The calmer your nervous system, the better your body can repair, regenerate and adapt.

 

5. Longevity Advantages

Here’s where it gets exciting. Research has linked regular sauna use to improved long-term health:


  • Cardiovascular Health: The heat gently elevates heart rate and improves blood vessel function, similar to light cardio exercise, supporting heart health over decades.
  • Cellular Health: Heat exposure triggers heat shock proteins, which help repair damaged cells and may protect against age-related decline.
  • Metabolic Benefits: Improved circulation and hormonal balance from sauna sessions may help regulate metabolism and support healthy weight maintenance.
  • Neuroprotection: Regular sauna use has been associated with lower risks of neurodegenerative diseases, potentially due to improved circulation to the brain and reduced inflammation.


In short: You’re not just recovering for tomorrow’s workout; you’re investing in how your body will feel years from now.

 

How to Use the Infrared Sauna Post-Workout


  • Timing: 15–30 minutes after exercise is ideal.
  • Hydration: Drink water before, during, and after your session.
  • Frequency: 2–4 times per week can offer noticeable benefits.

 

Final Word

Think of the infrared sauna as your workout’s finishing touch. It’s the bridge between today’s effort and tomorrow’s performance, and it gives you a head start on the kind of vibrant, pain-free, active life you want for years to come.


Your muscles will thank you tomorrow. Your future self will thank you decades from now.

What is the purpose of a cold plunge? Cold plunge helps reduce inflammation and muscle soreness. The list of health benefits is much longer. How long should I stay in the cold plunge? A good target time is three minutes. How often is it safe to cold plunge? It is recommended to cold plunge two to three times per week for a total of 11 minutes per week for metabolism-boosting results. What is infrared heat? Infrared is radiated heat. It penetrates human tissue, producing a host of anti-aging and health benefits. How often should I use an infrared sauna? It is recommended three to four days per week, for a total of 57 minutes per week for metabolic results. How will I feel after using an infrared sauna? Usually, the same as you do post-workout. Within 30 minutes, you should experience a boost in energy and mood. This should also result in a restful night’s sleep. Many other health benefits ensue. Do I burn calories while sweating? By increasing your core temperature and inducing sweating, infrared saunas increase blood flow and heart rate and can burn 400-600 calories in just one 30-minute session. What is Contrast Therapy? Contrast therapy is a method of alternating between hot and cold environments to induce certain physiological responses. It involves two to three rotations between the cold plunge tub and infrared sauna. When new to contrast therapy, it is recommended to start slowly. Ease into it by limiting the time spent in the sauna and the cold plunge. You can gradually increase the duration as your body adapts. What should I wear for the infrared sauna, cold plunge or Contrast Therapy? Bathing suits, loose clothing or athletic wear are recommended. How should I prepare for my session? Hydrate prior to your session. Do I need to bring a towel? Towels are provided in the private room and for showering (although we do not recommend showering after any of our services). Will I be sharing the room with anyone? Only if you bring a friend! Our room is private, whether you book a sauna, cold plunge or Contrast Therapy appointment. What is the HaloRed booth? The HaloRed booth has roots in a NASA study that measured the effects of light waves on salt particles in the Earth's atmosphere. The translucent, multi-sided salt crystals in our HaloRed system work by refracting light, creating billions of micro-bursts of red light, making it the most powerful and effective red light therapy available worldwide. During each session, red light waves energize and heat salt particles, enhancing their dryness and effectiveness beyond traditional halotherapy, offering a dual-benefit therapy unmatched in efficacy. How often can I do Red Light therapy? No more than once every 24 hours. All you really need is 5-15 minutes per day. What are the EMF levels of the HaloRed? Our booth is engineered to have low EMFs. However, anything with electric current running through it is going to generate some electromagnetic field. At the recommended usage distance of 6+ inches, our devices emit no detectable levels of EMF. What is Salt Therapy/Halotherapy? Halotherapy, also known as dry salt therapy, is a fast-growing holistic approach that mimics the microclimate of a salt cave. When you breathe in the micro-sized salt particles, they are immediately transported to every part of the respiratory tract, even the smallest alveoli and bronchioles. Then, the dry salt molecules dissolve and attract small impurities — the reason why it is called “the toothbrush of the lungs.” Salt therapy may eliminate the root of inflammatory respiratory illnesses in the lower and the upper tract, such as asthma, bronchitis and allergies, by destroying bacteria and restoring health and immunity. How often should I do Halotherapy for best results? The best results can be achieved when practiced regularly. The benefits are cumulative, so consistency and frequency are the key. People with chronic issues will benefit greatly from visiting salt rooms at least three to four times a week. What else should I know? Please refrain from using oils, creams, makeup and perfumes prior to your appointment. If needed, we have a shower you can use before your session. If you will be utilizing the cold plunge, bring a wet bag to carry your damp clothing after your session.

It’s almost time! Body Aligned’s Comprehensive Pilates Teacher Training in Tampa will begin in January 2024. Are you still on the fence about joining? In my last two blog posts ( Is Comprehensive Pilates Teacher Training Right for You and Considering Body Aligned Pilates Teacher Training ), I shared the enthusiasm of recent graduates as applied to a career as a Pilates instructor. But you don’t have to plan to teach for this training to be a great fit. Body Aligned’s Comprehensive Pilates Teacher Training is equally beneficial to those who simply want to improve their practice — with no intention of teaching others. One of my past graduates recently told me about how Teacher Training has helped her become more aware of her own body and enhanced the classes she takes.
