Many divers assume post-dive fatigue is due to cold or exertion on a dive. However, we understand that taking a cold shower doesn&#8217;t make you sleepy. Neither does a hard workout in the gym.<\/p>\n\n\n\n<p>If you find yourself inexplicably fatigued, malaised, or sleepy after diving then it can be due to \u2018<a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/subclinical-dcs-decompression-stress-fatigue\/\"><em>decompression stress<\/em><\/a>\u2019.<\/p>\n\n\n\n<div class=\"scuba-b4-h2-2\" style=\"margin-top: 10px;margin-bottom: 10px;\" id=\"scuba-736704668\"><div class=\"scuba-adlabel\">Sponsored Link<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-9354033900485448\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-9354033900485448\" \ndata-ad-slot=\"2393012471\" \ndata-ad-format=\"auto\" data-full-width-responsive=\"false\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What-can-make-you-feel-tired-after-diving\"><\/span>What can make you feel tired after diving?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are a number of factors that can contribute to you feeling tired after diving. You have to be realistic about whether those factors are likely to have a strong physical effect on you during your dive.<\/p>\n\n\n\n<p>Common explanations for feeling tired after diving include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Thermal stress: <\/strong>getting cold burns calories<\/li>\n\n\n\n<li><strong>Exertion:<\/strong> hard physical work burns calories<\/li>\n\n\n\n<li><strong>Anxiety:<\/strong> intense stress burns calories<\/li>\n\n\n\n<li><strong>Sickness:<\/strong> being seasick makes you tired<\/li>\n<\/ul>\n\n\n\n<p>Be honest about whether those factors would be significant enough to account for the level of tiredness that you experience after diving. <\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Scuba diving is normally sedate and relaxing. You shouldn&#8217;t be exerted and breathless on a normal dive.<\/li>\n\n\n\n<li>Typically, you&#8217;ll consume fewer calories on a scuba dive than when light jogging. <\/li>\n\n\n\n<li>Being slightly chilled for a short while doesn&#8217;t deplete your energy. <\/li>\n\n\n\n<li><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/scuba-diving-stress-management-and-diver-panic\/\">High levels of stress<\/a> consumes mental energy to exhaust you are very obvious.<\/li>\n\n\n\n<li>If you are seasick, you won&#8217;t attribute tiredness to your dive.<\/li>\n<\/ul>\n\n\n\n<p>Very rarely will those factors be severe enough to explain why you feel excessively tired after diving. However, there is a very likely alternative. It is possible you have <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/understanding-m-values-eric-baker\/\">decompression<\/a> stress. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Feeling-tired-after-diving-may-be-decompression-stress\"><\/span>Feeling tired after diving may be decompression stress<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There is a scientific explanation for feeling inexplicably tired after diving. It has to do with creating small nitrogen bubbles that trigger your <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/decompression-sickness-immune-system\/\">immune system<\/a>. That issue is known as decompression stress.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What-is-decompression-stress\"><\/span>What is decompression stress?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Decompression stress is theorized to be a physiological effect that arises from too many <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/sub-clinical-decompression-sickness-stress-micro-bubbles\/\">micro-bubbles forming in your body on an ascent<\/a>. <\/p>\n\n\n\n<p>Micro-bubbles are tiny bubbles that are too small to cause you physical injury or be diagnosed as <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/types-decompression-sickness-dcs\/\">decompression sickness<\/a> (DCS). <\/p>\n\n\n\n<p>However, large numbers of micro-bubbles are <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/decompression-sickness-immune-system\/\">believed to trigger an immune response in the body<\/a>. Your body reacts to bubbles as a foreign invader, so your white blood cells are fooled into swarming to attack them. <\/p>\n\n\n\n<p>However, your immune system can do nothing about micro-bubbles. Luckily, they quickly disappear by themselves soon after you surface from your dive. <\/p>\n\n\n\n<p>As a result, your immune response has to switch itself off. As part of that shut-down process, there is a flood of hormones released into the body. One of those hormones is <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/17004850\/\">serotonin and it makes you feel tired and sleepy<\/a>. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What-are-the-symptoms-of-decompression-stress\"><\/span>What are the symptoms of decompression stress?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Decompression stress is considered a sub-clinical form of DCS. The following symptoms after diving are indicators of decompression stress:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Feeling inexplicably tired<\/li>\n\n\n\n<li>Sleepiness<\/li>\n\n\n\n<li>Lethargy and low-energy<\/li>\n\n\n\n<li>A general feeling of malaise<\/li>\n\n\n\n<li>An unusual decrease in vitality<\/li>\n<\/ul>\n\n\n\n<p>Importantly, those post-dive symptoms should not have an obvious cause. If you hadn&#8217;t slept well the night before diving, you might expect to feel tired. Likewise, if you had skipped breakfast, it might explain why you experienced low energy after a scuba dive. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What-causes-micro-bubbles-to-form-when-diving\"><\/span>What causes micro-bubbles to form when diving?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A small number of nitrogen micro-bubbles form during ascent on every scuba dive you conduct. Our dive computers are only programmed to avoid large, harmful, bubbles from forming. They are not concerned with small bubble and whether you feel tired after diving. <\/p>\n\n\n\n<p>However, a small number of micro-bubbles do not provoke a strong immune reaction. A large amount of micro-bubbles are needed to cause decompression stress. <\/p>\n\n\n\n<p>The following bad diving habits allow larger amounts of micro-bubbles to form:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Too fast ascents<\/li>\n\n\n\n<li><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/best-ascent-speed-scuba-diving\/#Slow-Versus-Best-Ascent-Speed\">Too slow ascents<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dan.org\/alert-diver\/article\/defensive-dive-profile-planning\/\" target=\"_blank\" rel=\"noreferrer noopener\">See-saw dive profiles<\/a><\/li>\n\n\n\n<li>Repetitive dives<\/li>\n\n\n\n<li>Poor <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/diving-buoyancy-control-tips\/\">buoyancy control<\/a> on safety stops<\/li>\n\n\n\n<li>Skipping safety stops<\/li>\n\n\n\n<li>Popping up to the surface quickly after safety stops<\/li>\n<\/ul>\n\n\n\n<p>Additionally, any of the normal precursors for <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/types-decompression-sickness-dcs\/\">decompression sickness<\/a> will increase the number of micro-bubbles forming in your body during ascent:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/diving-dehydration-and-dcs\/\">Dehydration<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dan.org\/health-medicine\/health-resource\/dive-medical-reference-books\/decompression-sickness\/contributing-factors\/#thermal-stress\" target=\"_blank\" rel=\"noreferrer noopener\">Getting cold on a scuba dive<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/dan.org\/health-medicine\/health-resource\/dive-medical-reference-books\/decompression-sickness\/contributing-factors\/#workload\" target=\"_blank\" rel=\"noreferrer noopener\">Heavy exertion during a dive<\/a><\/li>\n\n\n\n<li>Having a <a href=\"https:\/\/dan.org\/health-medicine\/health-resource\/health-safety-guidelines\/guidelines-for-patent-foramen-ovale-and-fitness\/\" target=\"_blank\" rel=\"noreferrer noopener\">Patent Foramen Ovale<\/a> (PFO)&nbsp;<\/li>\n\n\n\n<li><a href=\"https:\/\/alertdiver.eu\/en_US\/articles\/identifying-decompression-risk-factors\" target=\"_blank\" rel=\"noreferrer noopener\">Certain stages of the menstrual cycle<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.ddrc.org\/diving\/can-i-dive\/can-i-dive-if-obese\/\">High BMI<\/a> through fat-biased body composition<\/li>\n<\/ul>\n\n\n\n<div class=\"scuba-b4-h2-3\" style=\"margin-top: 10px;margin-bottom: 10px;\" id=\"scuba-4052417008\"><div class=\"scuba-adlabel\">Sponsored Link<\/div><script async src=\"\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-9354033900485448\" crossorigin=\"anonymous\"><\/script><ins class=\"adsbygoogle\" style=\"display:block;\" data-ad-client=\"ca-pub-9354033900485448\" \ndata-ad-slot=\"6151212517\" \ndata-ad-format=\"auto\" data-full-width-responsive=\"false\"><\/ins>\n<script> \n(adsbygoogle = window.adsbygoogle || []).push({}); \n<\/script>\n<\/div><h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How-to-prevent-feeling-tired-after-diving\"><\/span>How to prevent feeling tired after diving<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The good news is that you don&#8217;t have to feel tired after diving anymore! Follow these simple steps to ensure that you maintain your vitality and energy after scuba diving:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Use-nitrox\"><\/span>Use nitrox<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>One of the least understood <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/why-use-nitrox-diving-advantages-benefits\/\">benefits of nitrox when scuba diving<\/a> is that it reduces micro-bubble formation during ascent. In turn, this can <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/subclinical-dcs-decompression-stress-fatigue\/#Nitrox-NitrogenAbsorption-and-Release\">reduce decompression stress<\/a> and stop you from feeling tired after diving.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conduct-better-safety-stops\"><\/span>Conduct better safety stops<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Safety stops allow nitrogen to leave your body before you surface. In turn, this can prevent excess amounts of micro-bubbles from forming. The quality of your safety stops makes a big difference. For that reason, follow these tips:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Conduct safety stops with accurate buoyancy:<\/strong> Pressure fluctuates more in shallower water. Improve your buoyancy control so that you stay within 50cm (1.5ft) of your planned safety stop depth.<\/li>\n\n\n\n<li><strong>Use additional safety stops:<\/strong> The arbitrary 5m (16ft) stop for 3 minutes isn&#8217;t necessarily the best option. Consider adding further stops to reduce the speed of pressure change on your body. On deeper dives, it is a great idea to spend one minute at 9m (30ft). Also, add a couple of minutes at 3m (10ft) to reduce feeling tired after diving.<\/li>\n\n\n\n<li><strong>Ascend very slowly from your safety stop:<\/strong> After you have finished your safety stop, ascend very slowly to the surface. You should aim for a <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/best-ascent-speed-scuba-diving\/\">maximum ascent rate<\/a> of 3m (10ft) a minute. For example, try to spend at least 1\u20132 minutes between the safety stop and the surface.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Ascend-at-the-optimal-speed\"><\/span>Ascend at the optimal speed<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/best-ascent-speed-scuba-diving\/\">Ascend at the optimal speed<\/a> of 9m (30ft) per min between the bottom and your safety stop. Definitely <a href=\"https:\/\/dan.org\/alert-diver\/article\/ascent-rates\/\" target=\"_blank\" rel=\"noreferrer noopener\">don&#8217;t ascend faster<\/a>. However, you should also avoid crawling up to the surface at a slower speed. Too slow ascents from depth are proven to increase bubble formation. <\/p>\n\n\n\n<p>It is very counter-intuitive to consider that slow ascent speeds would cause more bubbles. The DAN study below illustrates that a slow ascent rate of 3m (10ft) per minute causes significantly more bubbles than ascending at 9m (30ft) per minute.<\/p>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/03\/DAN-What-Ascent-Profile-For-The-Prevention-Of-Decompression-Sickness.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of DAN-What-Ascent-Profile-For-The-Prevention-Of-Decompression-Sickness.\"><\/object><a id=\"wp-block-file--media-ef74f945-c2cb-47ec-bc2e-d5ac687db26f\" href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/03\/DAN-What-Ascent-Profile-For-The-Prevention-Of-Decompression-Sickness.pdf\">DAN-What-Ascent-Profile-For-The-Prevention-Of-Decompression-Sickness<\/a><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2023\/03\/DAN-What-Ascent-Profile-For-The-Prevention-Of-Decompression-Sickness.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-ef74f945-c2cb-47ec-bc2e-d5ac687db26f\">Download<\/a><\/div>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Use-square-dive-profiles\"><\/span>Use square dive profiles<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Changes in pressure cause micro-bubbles to form.

Consequently, it is important to allow ample time for those bubbles to disappear before you dive again. Additionally, waiting longer before your next dive allows more nitrogen to leave your body. In turn, you will produce fewer micro-bubbles on the subsequent dive.<\/p>\n\n\n\n<p>For those reasons, your surface interval between dives should be at least one hour. Ideally, you should wait longer. As a result, you won&#8217;t feel as tired after diving.<\/p>\n\n\n\n<p>Descending with micro-bubbles remaining in your body does not get rid of them. They will crush in size as you descend, but more nitrogen will go inside them. As a result, they&#8217;ll re-grow even larger as you ascend.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Limit-repetitive-diving\"><\/span>Limit repetitive diving<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>When you go on a scuba diving vacation it is tempting to cram in as many dives as possible each day. However, you are taught during open water diver certification that this causes residual nitrogen to accumulate. In turn, that residual nitrogen causes more micro-bubbles to form on subsequent dives as you ascend.<\/p>\n\n\n\n<p>Limiting the number and depth of your dives will prevent decompression stress. Instead of feeling tired after diving, you will better enjoy your vacation evenings. Furthermore, you won&#8217;t feel fatigued and exhausted after diving for a couple of days.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Improve-your-hydration\"><\/span>Improve your hydration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>When you are dehydrated your blood thickens. This reduces your ability to get rid of nitrogen. In turn, you will produce more micro-bubbles as you ascend. <\/p>\n\n\n\n<p><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/diving-dehydration-and-dcs\/\">Active hydration is important when you dive<\/a>. This is especially true when you are on a scuba diving vacation in a tropical destination.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"You-dont-need-to-feel-tired-after-diving\"><\/span>You don&#8217;t need to feel tired after diving<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>In conclusion, feeling tired after diving isn&#8217;t normal. Post-dive fatigue can often be attributed to decompression stress. This arises due to the formation of tiny bubbles in the body as you ascend. You may have decompression stress if you feel lethargic, fatigued, sleepy, or malaised after diving. Importantly, these symptoms are not something that you have to put up with as a scuba diver. <\/p>\n\n\n\n<p>To stop feeling tired after diving, you can take several precautions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Perform more effective safety stops<\/li>\n\n\n\n<li>Ascend at the optimal speed<\/li>\n\n\n\n<li>Minimize depth fluctuation <\/li>\n\n\n\n<li>Take longer surface intervals<\/li>\n\n\n\n<li>Limit repetitive diving<\/li>\n<\/ul>\n\n\n\n<p>Do remember that using <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/why-use-nitrox-diving-advantages-benefits\/\">nitrox<\/a> is helpful in reducing micro-bubble formation. Also, consider that your diving computer only plans to keep you safe from large, harmful, bubbles. <\/p>\n\n\n\n<p>Follow the simple but effective measures described in this article and you can avoid feeling tired after diving. Instead, start enjoying a more energetic and revitalized dive experience!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"References-about-feeling-tired-after-diving\"><\/span>References about feeling tired after diving<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/subclinical-dcs-decompression-stress-fatigue\/\">Subclinical DCS, Decompression stress, and post-dive fatigue<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/best-ascent-speed-scuba-diving\/\">The best ascent speed for scuba diving<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/why-use-nitrox-diving-advantages-benefits\/\">The three benefits of nitrox for scuba divers<\/a><\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-dots\"\/>\n\n\n\n<div class=\"wp-block-columns alignwide is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-content-justification-center is-layout-constrained wp-block-column-is-layout-constrained\" style=\"flex-basis:25%\">\n<p><\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-medium is-resized is-style-default\"><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/andy-davis-technical-diving\/\"><img decoding=\"async\" width=\"300\" height=\"296\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2018\/03\/Cartoon-Andy-900x900-1-300x296.png\" alt=\"Andy Davis Technical Sidemount Wreck Diving Subic Bay Philippines RAID Courses Training\" class=\"wp-image-6812\" style=\"width:225px;height:222px\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2018\/03\/Cartoon-Andy-900x900-1-300x296.png 300w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2018\/03\/Cartoon-Andy-900x900-1-1024x1009.png 1024w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2018\/03\/Cartoon-Andy-900x900-1-768x757.png 768w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2018\/03\/Cartoon-Andy-900x900-1.png 1280w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-constrained wp-block-column-is-layout-constrained\" style=\"flex-basis:75%\">\n<h2 class=\"wp-block-heading has-text-align-center\"><span class=\"ez-toc-section\" id=\"About-The-Author\"><\/span>About The Author<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><a href=\"https:\/\/buymeacoffee.com\/andydavistech\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"274\" height=\"77\" src=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/bmc-button-1-1.png\" alt=\"\" class=\"wp-image-27046\" srcset=\"https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/bmc-button-1-1.png 274w, https:\/\/scubatechphilippines.com\/scuba_blog\/wp-content\/uploads\/2022\/12\/bmc-button-1-1-250x70.png 250w\" sizes=\"(max-width: 274px) 100vw, 274px\" \/><\/a><\/figure>\n\n\n\n<p><a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/andy-davis-technical-diving\/\">Andy Davis<\/a> is a <a href=\"https:\/\/scubatechphilippines.com\/raid-diving-courses-philippines\/raid\/\">RAID<\/a>, PADI TecRec, ANDI, BSAC, and SSI-qualified independent <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/what-is-technical-diving\/\">technical diving<\/a> instructor who specializes in teaching <a href=\"https:\/\/scubatechphilippines.com\/sidemount-courses\/\">sidemount<\/a>, <a href=\"https:\/\/scubatechphilippines.com\/technical-diving-courses\/\">trimix<\/a>, and <a href=\"https:\/\/scubatechphilippines.com\/technical-diving-courses\/\">advanced wreck<\/a> diving courses.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p>Currently residing in <a href=\"https:\/\/scubatechphilippines.com\/scuba_blog\/subic-bay-wreck-diving-sites\/\">Subic Bay, Philippines<\/a>; he has amassed more than 10,000 open-circuit and CCR dives over three decades of challenging diving across the globe.<\/p>\n\n\n\n<p>Andy has published numerous diving magazine articles and designed advanced certification courses for several dive training agencies, He regularly tests and reviews new dive gear for scuba equipment manufacturers.
