Abstract

Background

Sleep deprivation is a very common public health issue that has a negative impact on psychological health and cognitive function. Lack of sleep has been linked to mood problems, difficulty remembering, anxiety, nervousness, and a loss of "functioning”. The purpose of this study was to evaluate the impact of sleep loss on adults' self-reported psychological and cognitive functioning.

Methodology

A descriptive cross-sectional study was done with 110 adult participants. A structured questionnaire was used to collect demographic data such as age. Participants were asked to report the frequency of sleep deprivation and its associated effects on mood swings, forgetfulness, nervousness, anxiety, and brain fog with categorical responses (Never, Rarely, Sometimes, Often, Always). Data analysis was carried out by descriptive statistics, frequencies and percentages.

Results

The total number of participants in the study was 110. The majority (72.7%) were aged 36–45 years. Most of the participants stated that they sometimes experienced mood fluctuations due to lack of sleep (72.7%), and 13.6% often and 4.5% always. Sixty-eight per cent of participants reported forgetfulness occasionally and 18.2 per cent often. 54.5% of participants reported feeling nervous occasionally; 45.5% reported anxiety occasionally. One in two (54.5%) said they sometimes became sleep deprived and 18.2% always became sleep deprived. 45.5% of participants reported experiencing brain fog during normal daily activities sometimes.

Conclusion

Psychological and cognitive changes were frequently reported with sleep deprivation, such as moodiness, forgetfulness, nervousness, anxiety, and brain fog. These results point towards the significance of encouraging healthy sleep patterns for the betterment of mental health and cognitive function in adults.
