Naturally Combatting Insomnia

Naturally combatting insomnia

How many of us haven’t had trouble falling or staying asleep? According to the Public Health Agency of Canada, insomnia affects up to 50% of people. 1 in 2 Canadians have difficulty falling asleep or staying asleep, and 1 in 3 adults have trouble staying awake due to lack of sleep.[1]

Insomnia is a common public health issue,[2] and the prevalence of sleeplessness in adult Canadians continues to increase.[3] There are many factors that can affect our sleep, including caffeine consumption, alcohol consumption, stress levels, and other aspects of sleep hygiene. Fortunately, there are things we can do to help.

We can make changes for more attainable and sound sleep. Healthy habits to support healthy sleep are known as sleep hygiene. Coffee can help to start our day but can interfere with sleep when consumed past noon. We should also avoid consuming alcohol near bedtime. While alcohol can make it easier to fall asleep, these benefits are overshadowed by its negative effects on staying asleep. Exercising earlier in the day helps promote healthy sleep, though may disrupt sleep if done too close to bedtime. Keeping regular hours and minimizing daytime napping are also helpful.[4] Stress management is also vital to healthy sleep.

Bedtime routines are not just for children. Softer bedroom lighting and doing a relaxing activity before bed can be helpful. Laptops or phones should not be used at bedtime, as the blue light has been shown to suppress natural melatonin secretion, leading to sleeplessness.[5] Stretching and breathing exercises can induce the relaxation response, which helps to alleviate stress and improve sleep quality.[6]

Dietary supplements are a non-habit-forming  way to support sleep quality. Ashwagandha root, from the Withania somnifera plant, has been used in traditional Ayurvedic medicine for centuries.  Ashwagandha is an adaptogen that may help increase resistance to stress, and is also used as a sleep aid. It has been shown to decrease the time to fall asleep as well as improve overall sleep quality.[7]

Melatonin helps to reduce the time it takes to fall asleep in those who fall asleep slowly,[8] a more common issue in stressful times. It is normally produced by the pineal gland, though natural secretion is decreased by the blue light from electronic screens.[5] It can also be used to regulate sleep that is disrupted, such as occurs in jet lag.

GABA (gamma-aminobutyric acid) and L-theanine help to promote temporary relaxation, [9,10] and may also help to support healthy sleep. These two supplements are often used together.[11] In addition, 5-HTP can help to promote healthy mood balance as well as supporting healthy sleep. [12,13]

We don’t need to suffer from insomnia or sleeplessness. By supporting sleep hygiene, avoiding stimulatory substances or activities near bedtime, and using dietary supplements as needed, we can support healthy and sound sleep.
