Poor sleep has significant consequences for both health and performance. Chronic sleep deprivation is linked to an increased risk of cardiovascular diseases, diabetes, and obesity, with insufficient sleep raising the risk of developing these conditions by up to 30% (Walker, 2017; Afshin et al., 2019). In the UK, it’s estimated that one in three adults regularly fail to get enough sleep, placing a growing strain on healthcare systems (Public Health England, 2018). Sleep deprivation directly impacts cognitive performance, impairing memory, decision-making, and concentration. Research shows that getting fewer than six hours of sleep per night can impair cognitive function to a level equivalent to being over the legal alcohol limit for driving in the UK (Harrison & Horne, 2000; CHTF, 2020). Additionally, sleep is critical for physical performance and recovery; athletes who experience poor sleep see declines in strength, endurance, and recovery (Fullagar et al., 2015). On the other hand, consistent, restorative sleep enhances both physical and cognitive performance, supports immune function, and increases life expectancy by reducing the risk of age-related diseases such as Alzheimer’s (Lo et al., 2016; Van Cauter & Knutson, 2008). Prioritizing sleep is essential for long-term health, performance, and well-being.
