Common wisdom suggests that we should dodge exercising during the hottest parts of the day, increase our hydration, and perhaps even take a break from being active, which can lead to a sedentary lifestyle. Adapting our exercise and rest routines to accommodate the sweltering heat is essential.<\/p>\n<p><!-- BREAK 1 --> <\/p>\n<h2>The Thermal Shock<\/h2>\n<p>When we exercise, our muscles create energy; however, only about 20-25% of this energy translates into mechanical movement. The rest is released as heat. Adding a hot environment complicates matters, leading the body to face a double thermoregulatory challenge.<\/p>\n<p>According to a comprehensive <a rel=\"noopener, noreferrer nofollow\" href=\"https:\/\/journals.physiology.org\/doi\/full\/10.1152\/physrev.00038.2020\" target=\"_blank\">2021 review<\/a>, during heat stress, our bodies divert a considerable amount of blood to the skin to help dissipate heat through sweat. This blood diversion results in reduced availability for working muscles and the heart, causing heart rates to skyrocket and leading to quicker exhaustion.<\/p>\n<p><!-- BREAK 2 --><\/p>\n<h2>Embracing Acclimatization<\/h2>\n<p>Fortunately, our bodies are remarkable heat adapters. By progressively exposing ourselves to heat, we activate a process known as acclimatization. A <a rel=\"noopener, noreferrer nofollow\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/38051495\/\" target=\"_blank\">study published in 2024<\/a> quantified this process, showing that participants who were repeatedly exposed to heat could lower their resting core temperature by 0.19 \u00baC and their heart rate by 6 beats per minute.<\/p>\n<p>Following a structured acclimatization process of <a rel=\"noopener, noreferrer nofollow\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/38051495\/\" target=\"_blank\">8 to 14 days<\/a> improves both performance and thermoregulation. Cardiac adaptations begin to manifest as early as the fifth day.<\/p>\n<p><!-- BREAK 3 --><\/p>\n<h2>Understanding the Physiology<\/h2>\n<p>During the first week of heat training, the body retains more water and sodium, which helps increase blood volume circulation in the arteries and veins. This effectively enhances cardiac output and oxygen delivery to the muscles.<\/p>\n<p>Moreover, if the thermal stimulus is maintained long-term, the body produces more hemoglobin\u2014the oxygen-transporting protein in our blood\u2014leading to a more efficient training experience as muscles receive more oxygen.<\/p>\n<p><!-- BREAK 4 --><\/p>\n<h2>Guidelines for Training in Heat<\/h2>\n<p>Although training in the heat offers physiological benefits, it\u2019s not advisable to conduct high-intensity workouts at peak temperatures, such as a sweltering August afternoon, due to the risk of heatstroke. A gradual approach is essential: start with short, low-intensity sessions and progressively increase duration over two weeks.<\/p>\n<p>Hydration is also vital; losing more than 2% of body weight through dehydration can nullify the benefits of acclimatization and dangerously raise internal body temperatures. Thus, training in heat can indeed be challenging, but with a sensible approach that involves adjusting training schedules to cooler times, adapting is possible.<\/p>\n<p><!-- BREAK 5 --><\/p>\n<p>Image | <a rel=\"noopener, noreferrer nofollow\" href=\"https:\/\/unsplash.com\/es\/@unsplash?utm_source=unsplash&amp;utm_medium=referral&amp;utm_content=creditCopyText\" target=\"_blank\">Unsplash<\/a><\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/teknomers.com\/category\/general\/\" rel=\"dofollow\">General News &#8211; 2<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Summer is upon us, and as temperatures rise, engaging in outdoor sports like running or cycling can feel daunting.
