It looks like a kid\u2019s game, but\u2026 what if I told you that behind this lies one of the most powerful techniques to care for and improve your voice?<\/strong><\/p>\n<p data-start=\"5721\" data-end=\"5965\">Today I want to talk to you about <strong data-start=\"5755\" data-end=\"5766\">Lax Vox<\/strong>, also known as straw resistance exercises in water (SOVT in water). A classic that, if you\u2019re a singer, teacher, or simply use your voice intensely, can change your life (or at least your voice \ud83d\ude0a).<\/p>\n<h3 data-start=\"5967\" data-end=\"5995\">What exactly is Lax Vox?<\/h3>\n<p data-start=\"5997\" data-end=\"6241\">It is a vocal exercise in which you speak or sing while blowing through a straw submerged in a bottle of water. This gentle resistance generates positive pressure in the larynx, helping the vocal folds vibrate with more freedom and less effort.<\/p>\n<p data-start=\"6243\" data-end=\"6328\">In other words: you\u2019re doing a mini vocal physiotherapy session without realizing it!<\/p>\n<h3 data-start=\"6330\" data-end=\"6365\">Benefits (and they\u2019re numerous)<\/h3>\n<ul data-start=\"6367\" data-end=\"6554\">\n<li data-start=\"6367\" data-end=\"6418\">\n<p data-start=\"6369\" data-end=\"6418\">Enhances resonance and projection of the voice.<\/p>\n<\/li>\n<li data-start=\"6419\" data-end=\"6457\">\n<p data-start=\"6421\" data-end=\"6457\">Reduces vocal tension and fatigue.<\/p>\n<\/li>\n<li data-start=\"6458\" data-end=\"6500\">\n<p data-start=\"6460\" data-end=\"6500\">Aids recovery after intense vocal use.<\/p>\n<\/li>\n<li data-start=\"6501\" data-end=\"6554\">\n<p data-start=\"6503\" data-end=\"6554\">Promotes alignment of airflow and muscular balance.<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"6556\" data-end=\"6704\">Lax Vox is ideal before a concert, after a long class, or even to warm up your voice while driving (spoiler: don\u2019t mess up the inside of your car!).<\/p>\n<h3 data-start=\"6706\" data-end=\"6739\">Where does Lax Vox come from?<\/h3>\n<p data-start=\"6741\" data-end=\"7357\">Lax Vox was created in the early 1990s by Finnish speech therapist <strong data-start=\"6808\" data-end=\"6833\">Marketta Sihvo, Ph.D.<\/strong>, who began presenting this straw-and-bottle method at international conferences from 1991 <a href=\"https:\/\/www.laxvox.com\/history\/\">1<\/a>. The idea arose when she observed how her clients quickly perceived the relaxing and facilitating effect of the straw submerged in water. Later, otolaryngologist <strong data-start=\"7086\" data-end=\"7105\">Ilter Denizoglu<\/strong> proposed explanations on how positive pressure within the larynx releases tension and expands the vocal tract. Additionally, this technique evolves from an earlier Finnish tradition of resonance tubes from the 1960s, attributed to <strong data-start=\"7337\" data-end=\"7356\">Antti Sovij\u00e4rvi<\/strong>\u00a0<a href=\"https:\/\/www.vocalfeel.com\/en\/scientific-history\/\">2<\/a><\/p>\n<h3 data-start=\"7359\" data-end=\"7385\">What does science say?<\/h3>\n<p data-start=\"7387\" data-end=\"7455\">Scientific research has reviewed Lax Vox with very positive results:<\/p>\n<ul>\n<li data-start=\"7457\" data-end=\"7650\">\n<p data-start=\"7460\" data-end=\"7650\"><strong data-start=\"7460\" data-end=\"7480\">Healthy teachers<\/strong>: <strong>a pilot study with healthy educators showed improvements in vocal quality, phonation time, vocal function, and self-assessment after three weeks of regular exercises<\/strong> <b><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0892199716300479\">3,<\/a> <a href=\"http:\/\/\u00c7akan Uzunkavak, M., &amp; G\u00fcl, G.

It\u2019s compact, effective, and you can do it wherever you are (even in a car or public transport).<\/p>\n<p data-start=\"9392\" data-end=\"9878\">I once had an important performance and a strong viral pharyngitis. I wasn\u2019t aphonic, but my voice wasn\u2019t at 100\u202f%, and the repertoire was demanding. Of course, I couldn\u2019t rest my voice completely. I began a daily Lax Vox routine (three times a day, a few minutes each) and\u2026 I won\u2019t say it healed me, but I will say it was key to being able to perform with dignity, with enough voice and\u2014most importantly\u2014without hurting myself. Since then, I consider it part of my basic vocal toolkit.<\/p>\n<blockquote class=\"instagram-media\" style=\"background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15);
