Introduction

When a person has a cold, viruses or bacteria cause inflammation in the nasal cavity, leading to congestion and swelling of the nasal mucosa. At the same time, increased breathing rate accelerates water loss, making the mucosa dry and fragile. If minor capillary rupture occurs due to forceful nose-blowing or dry nasal passages, resulting in minimal bleeding that can be quickly stopped by applying pressure, this is a common phenomenon mainly representing a localized reaction caused by upper respiratory tract infection.

It is normal to experience minor nosebleeds during a cold if they result from dryness or inflammation of the nasal mucosa and are easily stopped. However, frequent or heavy bleeding, or nosebleeds accompanied by other severe symptoms, are not normal. If abnormalities occur, prompt medical attention is advised. Detailed explanation is as follows:

During a cold, viruses or bacteria can cause nasal inflammation, leading to congestion and swelling of the nasal mucosa. Meanwhile, increased respiratory rate causes moisture loss, leaving the mucosa dry and fragile. Minor rupture of capillaries due to forceful nose-blowing or nasal dryness may cause slight bleeding, which is easily stopped by applying pressure. This is a common phenomenon mainly caused by localized reactions from upper respiratory tract infection and will usually resolve on its own as the cold improves.

However, if nosebleeds frequently occur during a cold, if the bleeding is heavy and difficult to stop, or if symptoms such as persistent high fever, skin bruising, or gum bleeding accompany the nosebleeds, it may indicate complications such as blood disorders, severe nasal pathology, or abnormal coagulation function caused by drug misuse. These situations are not considered normal and require timely medical evaluation to identify the underlying cause and prevent worsening of the condition.

During a cold, avoid blowing your nose forcefully and keep the nasal passages moist. Using saline solution to rinse the nasal cavity can help relieve discomfort. If nosebleeds recur frequently or involve heavy bleeding, seek medical attention promptly and follow the doctor's instructions for appropriate treatment.

Why does sniffing cause coughing?

Sniffing can cause coughing, possibly due to postnasal drip, sensitive respiratory mucosa, allergic rhinitis, acute upper respiratory tract infection, or sinusitis. This can be improved by nasal irrigation, avoiding irritants, and medication. If coughing is frequent or accompanied by fever or worsening runny nose, prompt medical attention is needed.
