About this study

The body has a natural 24-hour rhythm. This rhythm affects factors like body temperature, sleep and Heart Rate Variability (HRV). Dietary choices influence these physiological processes of the body. Poor sleep quality can increase stress and raise levels of a hormone called cortisol, affecting our heart and insulin levels. Heart rate variability (HRV) which is the time between heartbeats, is also influenced by sleep and the body's rhythm. Lower HRV levels have been linked to heart and mental health issues. Little research is present on the effects of post-dinner snacks and pre-breakfast interventions on sleep quality, Heart Rate Variability (HRV), temperature, Interleukin-6, and cortisol levels. It is hypothesised that eating a post-dinner snack and first pre-breakfast will affect sleep quality, heart rate variability, IL -6, cortisol levels and temperature in healthy males.
