As a diver descends, the ambient <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> in the water increases, leading to a disparity between the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> inside the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> and the surrounding water <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a>. If the diver fails to equalize the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> in the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>, the resulting suction effect can cause discomfort, tissue swelling, and even permanent damage. To prevent <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a>, divers must be aware of the need to equalize their <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">masks<\/a> and understand the proper techniques for doing so.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Causes and Mechanism<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When a diver descends into deeper water, the increasing water <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> compresses the <a href=\"https:\/\/www.divertown.com\/en\/air\/\">air<\/a> in the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>. This causes a partial vacuum to form within the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>, creating a suction effect on the diver&#8217;s face and eyes. If the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> is not equalized, the blood vessels in the face and eyes can be subjected to undue stress, leading to tissue swelling and capillary damage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The likelihood of <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a> increases with the rapidity of descent and the depth attained. The greater the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> difference between the inside of the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> and the surrounding water, the more severe the potential consequences. <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">Mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a> is not typically a problem during slow, controlled descents, as the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> difference remains manageable.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Symptoms and Consequences<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The symptoms of <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a> can range from mild discomfort to severe pain, and may include:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Sensation of tightness or <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> on the face and eyes.<\/li>\n\n\n\n<li>Redness and bruising around the eyes and face.<\/li>\n\n\n\n<li>Swelling of the face, particularly around the eyes.<\/li>\n\n\n\n<li>Subconjunctival hemorrhage (broken blood vessels in the white part of the eye).<\/li>\n\n\n\n<li>In severe cases, retinal detachment or permanent vision loss.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">If a diver suspects they are experiencing <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a>, they should ascend slowly to a shallower depth and equalize the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> in their <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>. Continuing to dive without addressing the issue can result in lasting damage to the facial tissues and eyes.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Prevention and Equalization Techniques<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The key to preventing <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a> is learning to equalize the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> in the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> regularly and effectively during a dive. Here are some techniques divers can use to achieve this:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Exhale gently through the nose: By exhaling gently through the nose, a diver can create a positive <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> within the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>, helping to balance the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> inside and outside the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>. This method is the most straightforward and can be performed throughout the descent.<\/li>\n\n\n\n<li>Press and blow: This technique involves placing gentle <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> on the top of the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> while simultaneously exhaling through the nose. This creates a seal between the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> and the face, allowing the <a href=\"https:\/\/www.divertown.com\/en\/air\/\">air<\/a> <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> inside the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> to increase and equalize with the surrounding water <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a>.<\/li>\n\n\n\n<li>Finger <a href=\"https:\/\/www.divertown.com\/en\/equalization\/\">equalization<\/a>: If the previous techniques are insufficient, a diver can insert a finger under the edge of the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> to create a small opening, allowing <a href=\"https:\/\/www.divertown.com\/en\/air\/\">air<\/a> to flow in and equalize the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a>. This method should be used cautiously, as it can momentarily break the seal between the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> and the face, potentially allowing water to enter.<\/li>\n\n\n\n<li>Choose a low-volume <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>: Low-volume <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">masks<\/a> sit closer to the face, resulting in a smaller <a href=\"https:\/\/www.divertown.com\/en\/air\/\">air<\/a> space that is easier to equalize. This can help to reduce the risk of <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a>, especially for divers who have difficulty equalizing their <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">masks<\/a> using other techniques.<\/li>\n<\/ol>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Additional Factors and Considerations<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are several factors that may increase a diver&#8217;s susceptibility to <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a> or make <a href=\"https:\/\/www.divertown.com\/en\/equalization\/\">equalization<\/a> more challenging:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Nasal congestion: A diver with nasal congestion may have difficulty exhaling through their nose, making it challenging to equalize the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> in the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>. In such cases, it is advisable to postpone diving until the congestion clears or to use a decongestant before the dive, as recommended by a healthcare professional.<\/li>\n\n\n\n<li>Facial hair: Divers with facial hair may experience difficulties creating a proper seal between the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> and their face, potentially increasing the risk of <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a>. Trimming facial hair or applying a thin layer of petroleum jelly to the beard or mustache can help create a better seal.<\/li>\n\n\n\n<li>Ill-fitting <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>: A <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> that does not fit properly can make <a href=\"https:\/\/www.divertown.com\/en\/equalization\/\">equalization<\/a> more difficult, as well as increase the likelihood of water entering the <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>. Divers should ensure that their <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> fits securely and comfortably, with a snug seal around the face.<\/li>\n\n\n\n<li>Inexperience or anxiety: Inexperienced divers or those with anxiety about diving may be more prone to rapid descents, increasing the risk of <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a>. Proper dive training and practice, as well as relaxation techniques, can help to alleviate anxiety and promote controlled descents.<\/li>\n<\/ol>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Treatment and Recovery<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If a diver experiences <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a>, they should immediately cease their descent, ascend slowly to a shallower depth, and equalize the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> in their <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">mask<\/a>. In mild cases, symptoms such as redness and swelling may resolve on their own within a few hours to a few days. Over-the-counter pain relievers and anti-inflammatory medications can help alleviate discomfort and reduce inflammation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In cases of subconjunctival hemorrhage, the affected eye may appear bloodshot but should not be painful. The condition typically resolves on its own within one to two weeks. However, if pain, vision changes, or other concerning symptoms develop, the diver should seek medical attention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For severe cases involving retinal detachment or other serious eye injuries, prompt medical evaluation and treatment are crucial. Divers should not attempt further dives until cleared by a healthcare professional, as additional dives may exacerbate the damage.<\/p>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Key Takeaways<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">Mask<\/a> <a href=\"https:\/\/www.divertown.com\/en\/squeeze\/\">squeeze<\/a> is a preventable condition that can cause significant discomfort and potential harm to divers who do not equalize the <a href=\"https:\/\/www.divertown.com\/en\/pressure\/\">pressure<\/a> in their <a href=\"https:\/\/www.divertown.com\/en\/diving-mask\/\">masks<\/a> during rapid descents.
