Scientifically, it is called dyspnea. Shortness of breath occurs when the airways to our lungs become narrowed or blocked for some reason. Here are the 5 main scientific reasons behind this:<\/p>\n<p>Asthma and inflammation of the bronchial tubes: The most important scientific reason for shortness of breath is asthma. In this condition, the small tubes in the lungs (bronchioles) become very sensitive due to chronic inflammation. When you inhale cold air or dust, these bronchial tubes suddenly constrict (bronchospasm) and fill with mucus, completely blocking the flow of air.<\/p>\n<p>&nbsp;<\/p>\n<div class=\"jetpack-video-wrapper\"><iframe loading=\"lazy\" title=\"\u0d36\u0d4d\u0d35\u0d3e\u0d38\u0d02 \u0d2e\u0d41\u0d1f\u0d4d\u0d1f\u0d41\u0d28\u0d4d\u0d28\u0d35\u0d7c \u0d32\u0d48\u0d02\u0d17\u0d3f\u0d15 \u0d2c\u0d28\u0d4d\u0d27\u0d24\u0d4d\u0d24\u0d3f\u0d7d \u0d38\u0d41\u0d30\u0d15\u0d4d\u0d37\u0d3f\u0d24\u0d2e\u0d3e\u0d2f\u0d3f \u0d0f\u0d7c\u0d2a\u0d4d\u0d2a\u0d46\u0d1f\u0d3e\u0d7b \u0d07\u0d24\u0d3e\u0d23\u0d4d \u0d0e\u0d33\u0d41\u0d2a\u0d4d\u0d2a\u0d2e\u0d3e\u0d7c\u0d17\u0d02 Dr Ajayan Varghese\" width=\"930\" height=\"523\" src=\"https:\/\/www.youtube.com\/embed\/ENM1bDlC05s?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<p>Allergies and Air Pollution (Allergic Bronchitis): Inhaling dust particles in the air, smoke from vehicles, mosquito repellent smoke, strong smells of paint and perfume, pollen, and mold can cause sudden allergies in the lungs. This causes the body to produce a chemical called histamine, which doubles the difficulty in breathing.<\/p>\n<p>COPD or Chronic Obstructive Pulmonary Disease (COPD): This is a fatal condition that is seen in long-term smokers and those who constantly breathe wood smoke in the kitchen. People with Chronic Obstructive Pulmonary Disease (COPD) experience permanent damage to the air sacs (alveoli) in the lungs. This greatly reduces the body&#8217;s ability to absorb oxygen and causes chronic severe shortness of breath.<\/p>\n<p>Heart Failures: Shortness of breath is not always a problem of the lungs alone. When the heart is unable to pump blood properly to the body (Congestive Heart Failure), blood starts to back up in the blood vessels of the lungs (Pulmonary Edema). This fills the lungs with fluid and causes severe shortness of breath when lying down, especially at night.<\/p>\n<p>Anemia and Severe Anemia (Anemia \/ Low Hemoglobin): Anemia is a condition in which the level of hemoglobin in the blood is very low. Hemoglobin carries oxygen from the lungs to other cells in the body. When its level decreases, the body tries to breathe faster to get enough oxygen to the cells. This leads to severe shortness of breath even while doing small tasks.<\/p>\n<p>&nbsp;<\/p>\n<div class=\"jetpack-video-wrapper\"><iframe loading=\"lazy\" title=\"\u0d36\u0d4d\u0d35\u0d3e\u0d38\u0d02 \u0d2e\u0d41\u0d1f\u0d4d\u0d1f\u0d41\u0d28\u0d4d\u0d28\u0d35\u0d7c \u0d32\u0d48\u0d02\u0d17\u0d3f\u0d15 \u0d2c\u0d28\u0d4d\u0d27\u0d24\u0d4d\u0d24\u0d3f\u0d7d \u0d38\u0d41\u0d30\u0d15\u0d4d\u0d37\u0d3f\u0d24\u0d2e\u0d3e\u0d2f\u0d3f \u0d0f\u0d7c\u0d2a\u0d4d\u0d2a\u0d46\u0d1f\u0d3e\u0d7b \u0d07\u0d24\u0d3e\u0d23\u0d4d \u0d0e\u0d33\u0d41\u0d2a\u0d4d\u0d2a\u0d2e\u0d3e\u0d7c\u0d17\u0d02 Dr Ajayan Varghese\" width=\"930\" height=\"523\" src=\"https:\/\/www.youtube.com\/embed\/ENM1bDlC05s?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Sudden shortness of breath, severe shortness of breath while walking &hellip; <\/p>\n","protected":false},"author":9,"featured_media":31351,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-31350","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-job"],"acf":[],"jetpack_featured_media_url":"https:\/\/thozhilvarthalatest.com\/wp-content\/uploads\/2026\/06\/1-2026-06-03T172724.595.png","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=\/wp\/v2\/posts\/31350","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=31350"}],"version-history":[{"count":1,"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=\/wp\/v2\/posts\/31350\/revisions"}],"predecessor-version":[{"id":31352,"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=\/wp\/v2\/posts\/31350\/revisions\/31352"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=\/wp\/v2\/media\/31351"}],"wp:attachment":[{"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=31350"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=31350"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/thozhilvarthalatest.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=31350"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
