(It says “food grade” on the bag.) A 60 g bag costs about $40.IOS and iPadOS devices have built-in protections to prevent overheating. You can buy crystals on Amazon, but be sure to buy menthol crystals for food and not menthol crystals to put in the bath. The second technique is much simpler and involves depositing menthol crystals in water heated to a temperature above 40 ☌ (between 41 and 44 ☌) until the crystals dissociate. The first is more complex and consists of dissolving menthol crystals in a solution of ethanol (ethyl alcohol) to obtain the desired concentration. Two techniques exist to prepare a menthol drink.

Interventions that affect our psychology, for example the presence or absence of competitors, the use of music during an effort or the possibility of making money, can have a significant effect on our physiology, and therefore on our performance. our level of motivation to continue a difficult effort) and vice versa. Our physiology (how our muscles work during an effort) affects our psychology (e.g. It’s important to understand that physiology and psychology are two interrelated fields. Several studies have shown that the ingestion of menthol reduces the feeling of heat and reduces the perception of effort, which has the effect of improving performance during an effort until exhaustion, or a time trial in hot conditions. By altering our perception of heat, we alter how our brain perceives the effort we are providing, which can slightly alter our effort management and allow us to increase our intensity, or speed, a little. Our brain takes into consideration many variables, including the distance remaining to be traveled, the level of pain in our muscles, the temperature of our skin and different regions of the body, our perception of effort and our perception of heat. It is the brain that allows us to adjust our intensity, or speed, during a competition. In other words, menthol helps to fool the brain. Menthol is beneficial because it somehow makes the brain believe that it is less hot. You are probably wondering how bringing a feeling of cold, without actually cooling the skin or body, can be beneficial for performance in hot conditions. Unlike other cooling strategies, such as using a cooling jacket or ingesting slush that reduce the temperature of the body and/or skin, menthol only provides a feeling of cold. Related: Why training in the heat is good By rinsing the mouth, the menthol comes into contact with the receptors in the mouth and acts on them to bring a cooling sensation. It has even been shown that you don’t actually have to ingest the menthol solution – you can just rinse your mouth with the solution and then spit it out. So, when we apply a cream with menthol on our skin, or ingest a menthol solution, we feel a cold sensation. This receptor is present on our skin and even in our mouth. Menthol acts on a receptor called TRP-M8 (Transient Receptor Potential Melastatin-8) that detects cold. For several years, many researchers have been interested in using menthol to cool down (or at least to feel colder) in hot conditions. This substance brings a feeling of freshness and cold. Menthol is a substance found in many products, including toothpastes and chewing gum.
