Sleep patterns and health impacts of insufficient rest

Research indicates that approximately one in five people in the UK are not receiving adequate sleep, even when meeting the recommended seven to nine hours. Poor sleep is linked to impaired cognitive performance, weakened immune systems, and increased risks of obesity, diabetes, and cardiovascular disease.

As individuals age, sleep patterns naturally shift. Older adults often experience an earlier body clock, leading to increased sleepiness in the early evening and early waking, such as at 4am or 5am. This is often due to a weaker circadian rhythm, less time spent in deep sleep, and reduced light exposure.

Lifestyle factors including stress, late-night eating, and screen time contribute to sleep issues. Experts suggest that addressing nutrient gaps through botanicals like chamomile, which interacts with GABA receptors in the brain, may help improve sleep quality.
