- Sleep is a hormonal process - Circadian rhythm involves two hormones, melatonin and cortisol.
- Our sleep-wake cycle is in line with the earth's rotation around the sun. We sleep at night and are awake during the day.
- Hormone disruption - Artificial light impacts the hormone signalling that tells our body it is either time to sleep or be awake.
- Sleep hormones - Melatonin is the hormone that tells our body it is time for sleep in the evening and cortisol is the hormone that tells our body to wake up in the morning.
- Hunger hormone - Ghrelin, our hunger hormone, is increased when we are tired or sleep-deprived. Hence the feeling of being tired and hungry.
- Why not go to bed earlier? People enjoy their alone time in the evening when the kids are in bed and they can finally relax and have some time to themselves. Also screen addiction!
- Sleep Apnea - A new medical condition when people stop breathing during their sleep. Common in people who are overweight.
- The importance of prioritising sleep - Aim for at least 7.5 hours of sleep each night and work with your circadian hormones. Keep lighting low in the evening and avoid screen time just before bed.
