World Sleep Day - March 15th 2024

March 15th sees the dawn of this year’s World Sleep Day, and with up to 70 million people worldwide experiencing sleep issues,1 a good night’s sleep is on many people’s minds. Sleep is a fundamental part of health, and the rise in disturbances to sleep is now known to be contributing to global health concerns.2

Experts estimate that around 7 hours of sleep or more a night is optimal for most adults3 and that many people achieve far less than this. There are a wide variety of sleep disturbances that occur; this can range from issues falling asleep, staying asleep, waking early, or not getting enough restful sleep’, to sleep apnoea and insomnia – the chronic inability to sleep.?

Impact of sleep disruption?

Quality of sleep is just as important as quantity as it is a time when the body rests, repairs, regenerates, cleanses, and rebalances. A number of biochemical processes occur whilst asleep, and disruption to this is known to impact many aspects of physical health as well as mental health and wellbeing.?

The impact of poor sleep on physical health can not only lead to an increased risk of developing chronic health conditions, such as cardiovascular disease, stroke, obesity, and metabolic syndrome, but also impact mental health and behaviour. Disruption to sleep over time can have an impact on impulse control and decision making,1??2? increase the use of stimulants, alcohol, or other substances and also impair communication and social interaction. There is also a clear link between sleep and emotions. Anger, frustration, and irritability may be common emotions felt. Anxiety and depression are also prevalent in sleep disorders and affect around 50% of people with insomnia.21

Factors affecting sleep?

Sleep is under the control of two systems, the circadian rhythm - the internal body clock, and the sleep drive process. These systems work together to create a balance of alertness or sleepiness.??

The circadian rhythm is influenced by the presence of light stimulation on the retina, which then sends signals to the'master clock’, the Suprachiasmatic Nucleus (SCN) in the brain. This sets off hormone release – namely melatonin.??

Sleep drive is less well understood than the circadian rhythm, but what is known is that during waking hours, a chemical called adenosine builds up in the brain, stimulating the need for sleep. During sleep, adenosine falls– enhancing alertness.?

Factors that directly, or indirectly, affect the circadian rhythm or sleep drive system may lead to sleep disruption. This can include caffeine, alcohol, or other stimulant use, blood sugar imbalances, inactivity, exposure to blue light late in the day, stress, irregular work patterns or shift work.22?2? ?

A number of other factors also influence sleep and genetics can play a role, with insomnia running in families. Gender can also predispose a person to poor sleep patterns and women have a higher risk of developing sleep disruption at any age,2? particularly in the menopausal transition.21?

The environment also influences the ability to sleep and noise, light, and comfort can all prevent a good night’s rest.?

Proactive sleep hygiene?

It is easy to see why disruptions to sleep can have a profound impact on day-to-day living and many people are now taking a proactive approach to sleep issues. Sleep hygiene involves taking measures to enhance sleep drive and balance the circadian rhythm. ?

Steps frequently taken include creating a cool, comfortable, and dark sleeping environment, reducing exposure to blue light from digital devices in the evening, indulging in relaxing baths pre-bedtime and creating a regular bedtime routine. Increased exposure to light in the mornings, the use of a SAD light, and physical exercise are also commonly incorporated. More recently, interventions such as mindfulness, progressive relaxation, and the use of white, pink, or brown noise have also gained popularity.??

Sleep supplement intervention?

The desire to have a holistic approach to sleep has led to a rise in the use of sleep aids and an estimated 56% of adults with sleep difficulties have taken a sleep aid at some point.2?

One in three people have turned to sleep supplements in order to assist with difficulties2? and the global sleep supplement market is showing growth, with expectations to expand at a CAGR of 5.2% and reach a valuation of US$ 12.9 billion by 2034.2? ?

A variety of nutraceuticals show benefits to the sleep cycle, but top of the list for consumers is melatonin. The melatonin sleep supplements market is being predicted to expand between 2023 and 2033, reaching a value of around US$ 1055.6 million by 2033.2??

Increased consumer awareness of the role of melatonin in the circadian rhythm and sleep patterns, alongside an increased diversity of melatonin formats available, is likely driving the growth of the melatonin market.??

Trends in consumer demands for supplements in more versatile and easier to use forms, compared to standard tablets and capsules, has led to an increase in wellness gummies. Consumer preference is based on flavour, texture, and convenience, and there has been a rise in vegan nighttime gummies.?

IMCD sleep solution??

IMCD offers a variety of innovative, evidence-based solutions for relaxation and sleep, using technical expertise to meet consumer demands for palatable, functional formats that have enhanced lifestyle integration. Sleep Well is a vegan, orange blossom and raspberry flavour gummy that contains natural melatonin. Sleep Well is designed with consumer requirements in mind and not only provides actives promoting sleep support but also meets consumer demand for natural and sustainable alternatives. ?
