At Aion, we’ve designed our vests to do more than just add resistance—they harness the power of heat to elevate your performance. But to truly maximize this benefit, it helps to understand how heat impacts your body and how you can use it to your advantage. In this post, we’ll dive into the fascinating science behind heat and its effects on your physiology, showing you how Aion’s thermal technology works to make every movement more powerful, efficient, and impactful.
Understanding Heat and the Human Body
Heat plays a vital role in keeping your body running smoothly. It’s all part of a natural process called thermoregulation, where your body works to maintain the perfect temperature. This sweet spot is crucial for enzyme activity, cellular function, muscle function, overall vitality, and many more body processes.
Here’s how your body manages heat:
Heat Production: Powering Up from Within
Your body generates heat, a process called thermogenesis, in three ways:
- Through everyday cellular activity
- Exercise or physical activity
- Involuntary movement when needed (aka shivering)
Through cell metabolism, cells in your body use the fuel from food to produce energy and heat. Even when your body is at rest, your cells are constantly working, using fuel from food to create energy–and, in the process, giving off heat.
When you exercise or perform any physical activity, your body generates more heat because your cells are working more. In fact, up to 75-80% of the energy your body uses is released as heat during intense physical exercise. When exposed to cold conditions, your body can automatically initiate physical activity through shivering, generating more heat to regulate your body temperature.
Heat Loss: Cooling Down When It Counts
When your body gets too hot, it can regulate its temperature through the following heat-loss mechanisms:
Heat Acclimatization: Adapting and Thriving
Due to the natural thermoregulatory effects that the body goes through in the face of elevated temperature conditions, there is a growing interest in heat therapy and its benefits. By reaching temperatures slightly above the normal core body temperature, you can induce your body to undergo a potentially beneficial process called heat acclimatization. Most heat therapy studies report that a core body temperature of around 100-101°F is necessary for safe thermoregulatory response and beneficial heat acclimatization. Although some heat benefits of varying levels of magnitude have been reported at temperatures below and above this range.
But what is heat acclimatization?
It is simply the human body’s way of adapting to heat load. If done right, heat acclimatization ultimately improves body functions, physical performance, and exercise capacity.
When your body is subjected to heat load, your cardiovascular, cellular, metabolic, fluid-electrolyte, and thermoregulatory systems respond to protect your cells, power your systems, and make you comfortable. When you repeatedly perform physical activity while exposed to heat load, your body works hard to acclimatize to this strenuous activity and heat cycle.
Over time, this process strengthens your ability to handle challenging conditions, enhances endurance, and boosts your overall resilience. In other words, heat acclimatization doesn't just make you more comfortable in the heat—it makes you stronger, more capable, and ready to take on more, whether in your workouts or daily life.
The Power of Heat: How It Benefits Your Body
Heat isn’t just a byproduct of physical activity—it’s a powerful tool your body uses to optimize performance and recovery. Whether generated naturally through movement or enhanced by external sources like Aion’s Wearable Resistance™ vests, heat can unlock a range of benefits that elevate your fitness and well-being. Harnessing the benefits of heat can transform how your body moves, recovers, and feels. Aion’s innovative vests are designed to enhance your body's natural heat regulation, maximizing these benefits in every movement, whether working out or just going about your day.
1. Boosts Blood Circulation
When your body warms up, blood vessels dilate, allowing blood to flow more freely. This improved circulation delivers more oxygen and nutrients to your muscles, fueling them for better performance. Increased blood flow also helps flush out metabolic waste, speeding up recovery and reducing soreness after intense workouts. Heat therapy has been shown to improve cardiovascular health by increasing skin blood flow, which helps regulate body temperature and promotes heart health. Additionally, studies have found that regular heat exposure can lower the risk of cardiovascular disease and improve overall blood circulation.
2. Enhances Muscle Flexibility
Warm muscles are more flexible and less prone to injury. By promoting muscle elasticity, heat prepares your body for movement, reducing stiffness and the likelihood of strains or pulls. This is why athletes warm up before exercise—heat makes your muscles more pliable and ready for action. In fact, this research revealed that applying heat before stretching exercises increases tissue extensibility and range of motion, making muscles more flexible and preventing injuries.
3. Accelerates Recovery
Heat can work wonders after a workout too. It helps relax tense muscles, alleviates soreness, and promotes faster recovery by improving blood flow to the affected areas. Whether through active heat generated during exercise or the gentle warmth of Aion’s vests, this process aids in reducing post-exercise muscle fatigue. Many studies have demonstrated that heat therapy is effective in reducing muscle soreness after intense exercise by improving blood flow to the muscles, which aids in faster recovery and reduces inflammation.
4. Supports Metabolic Function
Your metabolism is a heat-driven process. When exposed to heat, your body increases its metabolic rate to dissipate excess heat and maintain its core temperature. This means your body can burn more calories and sustain higher energy levels during workouts.
This study found that heat exposure increases metabolic activity, promoting fat oxidation and energy expenditure. The findings suggest that regular heat therapy can boost metabolism and aid in weight management.
5. Eases Back Pain and Stiffness
Heat can be a natural form of relief for those dealing with back pain or stiffness. The warmth relaxes surrounding muscles and tissues, reducing tension and increasing mobility. This makes it easier to move freely and stay active without the constraints of pain or stiffness.
Recent studies highlight that heat therapy is particularly effective in alleviating pain from conditions like low back pain and neck pain, two of the most common causes of joint stiffness. By enhancing tissue perfusion and promoting relaxation, heat can significantly reduce pain and improve joint flexibility, making it a highly recommended option for managing chronic issues.
6. Elevates Mental Wellness
Let’s not forget the mental benefits. Heat triggers the release of endorphins—your body’s feel-good hormones. These endorphins lift your mood and help reduce stress and anxiety, giving you a mental boost along with the physical advantages.
