Perceptions of the Importance of Sleep in Common Cold—Two Online Questionnaire-Based Surveys

Abstract

Sleep deprivation affects the immune system and can render subjects more susceptible to symptoms associated with the common cold. The aim of this research was to investigate cold sufferers' and doctors' perceptions of the role of sleep in recovery from cold/flu. An online survey of 4000 adults who had suffered from cold/flu in the previous 12 months was conducted in eight countries and an online survey of 150 doctors was conducted in Germany. Responses were collected to questions regarding aspects of life affected by, and concerns while suffering from, cold/flu symptoms including nighttime awakening and actions taken to aid recovery. Responses were also collected to questions regarding advice given to cold/flu patients and the importance of sleep. Ability to sleep well was widely reported as negatively impacted by cold/flu (mean 46.1% of respondents across eight countries), especially in Western Europe, and inability to sleep well was a frequently reported concern associated with suffering from cold/flu (21.8%). To sleep more than usual was a frequently reported action taken to feel better (40.5%). Ninety-four percent of respondents reported waking up at night because of symptoms, cough being the most frequently reported symptom to awaken respondents. There was evidence of a possible relationship between sleep quality and medication taken at night for symptom relief. Countries with the highest proportions of respondents who reported sleep to be the aspect of life most negatively affected by a cold (France, Germany and Italy) were also those with the lowest proportions of respondents who reported that taking medications at night was the most effective way of getting back to sleep after waking due to cold symptoms. The majority of doctors believed sleep helped cold/flu patients to recover faster and that a good night's sleep was important. Sleep is widely considered to be important in promoting recovery from cold/flu. Hence, the relief of symptoms that disrupt sleep is also likely to be important for a faster recovery.

A real-world study of quality of life following treatment with xylometazoline hydrochloride in individuals with common cold

“… 1 Symptoms typically include nasal congestion, cough, sore throat, sneezing, runny nose, and headaches. 1 In addition, people with the common cold may also experience sleep disruption, 7 fatigue, 6 cognitive impairment, 6 , 8 and reduced alertness. 8 Consequently, these symptoms impact individuals’ quality of life (QoL), such as the performance of daily activities, and individuals’ occupational functions.…”
