To achieve the best sleep possible, our body needs to produce melatonin and serotonin. These hormones are released from our pineal gland which is located in the centre of our brains to regulate the sleep-wake cycle or circadian rhythm.
The pineal gland is relevant because it is sensitive to all types of light. When exposed to light in the form of laptops, kindles, mobile phones and alarm clocks, melatonin production is slowed down.
Therefore it is best to avoid using any of these devices close to bedtime. It is also be recommended to not turn on any lights when getting up in the night to go to the bathroom. If all else fails, a sleep mask is a great option to block out any artificial light.
Your circadian rhythm is your body’s internal clock. When your circadian rhythm is disrupted, the immediate issues are that your sleeping and waking systems are put out, resulting in feeling tired during the day, and awake at night.
