Sleep is essential for physical, mental and emotional health. The negative effects from lack of sleep are linked to a range of conditions from weight gain and obesity through to neurological disorders.
But for others, the experience is the opposite. A study in the US found that as much as one-third of American adults do not enjoy sufficient and regular sleep. This can lead to a reduction in overall health, compromised daily functioning and mood swings.
What happens when we sleep?
Sleep is governed by our circadian rhythms – which are like a biological clock in the brain. The sleep-inducing hormone melatonin is released when the brain senses that the intensity of light is reducing. Melatonin levels rise as night and reduce again once we sense light, which, according to biology, would be at daybreak.
- The first stage of falling to sleep from being awake
- The second stage of light sleep
- The third and fourth stages of deep sleep.
Research indicates sleep is essential for maintaining healthy brain plasticity, helping us process and remember things we learn and experience during the day. It is also important for repairing and restoring the body, replacing those cellular components used heavily during waking hours.
Is all sleep the same?
When we sleep during the day, the circadian rhythms can alter, becoming arrhythmic. These changes in biological rhythms can disrupt the metabolism and immune functions and effect inflammatory and stress responses. Sleeping during the day can also be a sign of sleep deprivation.
What promotes healthy sleep?
What we do during the day also affects our sleep. By achieving the recommended amount of daily exercise and enjoying physical activity throughout the day, you may feel less fatigued later in the day and reduce the needs for napping before you are due for your evening sleep.

What prevents healthy sleep?
Such signs of sleep deprivation may include sleeping during the day when reading, driving, riding on transport or sitting for a rest. Signs will vary from person to person.
Sleeping at the wrong time of the day can affect a healthy sleep pattern. It can lead to chronic health problems like heart disease, kidney disease, high blood pressure, stroke and depression – all of which can then affect a healthy sleep routine. It can be a vicious cycle of reduced health and reduced healthy sleep.
3 things you can try to improve your sleep
- Try to avoid eating a heavy meal and/or drinking caffeine before bed. A cup of warmed milk (even with a little honey, cinnamon and turmeric) can help settle digestion and prepare the body for sleep in place of more stimulating options.
- Wind down 2 hours before your bedtime, including preventing (or reducing) screen time; using lower lighting such as turning off unnecessary bright lights and maintaining adequate light with lamps.
- Be in bed, ready for sleep before 10pm, with the room nice and quiet, your TV off and mobile phones away.
