Too Tired to Sleep?

Ayurveda suggests sleep issues are linked to the body lacking energy reserves, rather than having too much energy. The Ayurvedic strategy for sleep is not to sedate an already exhausted body, but to rejuvenate and rebuild reserves so that we have the energy we needs to sedate ourselves and sleep deeply, naturally.

Taking the Ayurvedic herb ashwagandha before bed supports healthy sleep by rejuvenating the body and addressing stress-related exhaustion. Ashwagandha (Withania somnifera) has emerged as one of the world’s most powerful adaptogens, which means it helps the adrenal system regulate hormones and helps the body cope with stress. In fact, somnifera in Latin literally means sleep inducer.

Health Risks of Poor Sleep

Some 50 to 70 million Americans have trouble getting a good night’s sleep. New research has linked numerous health concerns to poor sleep. Brain lymphatics drain three pounds of toxins each year during sleep. The worse you sleep, the less efficiently the brain drains, and the less the brain drains, the less likely you will get a good night’s sleep.1,2

It is clear that the many shades of stress can dramatically affect one’s ability to sleep. Stress can alter the circadian clock, throw off blood sugar, flood the body with stress hormones, disturb production of neurotransmitters, alter the microbiome and deplete the body’s energy reserves—all factors linked to healthy sleep.

5 Ways Ashwagandha before Bed Supports Healthy Sleep

  1. Lowers Stress Hormones

One of the most well-understood pathways linked to sleep disturbance is overproduction of the stress hormone cortisol. According to our circadian clock, cortisol should naturally decrease in the early evening in preparation for sleep. Stress can overrule these rhythms and cortisol can stay elevated into the night and affect sleep success.

Ashwagandha, in numerous studies, has been shown to help control and limit production of cortisol as a result of stressful situations.3

  1. The Worry Effect

When the body is depleted, not only do we not have enough energy to put ourselves to sleep, we will also not have enough energy to calm the mind during the day, causing unnecessary worry.

Ashwagandha has been shown to positively affect neural receptors responsible for receiving GABA, an important neurotransmitter in reducing neuronal excitability. Appropriate GABA levels are critical to settling the mind and offsetting the tendency to worry.4

  1. The Blood Sugar Effect

One of the main reasons people wake up at night is because blood sugar levels crash during sleep. The body is designed to burn fat at night, breaking the fast with breakfast. If blood sugar levels are unstable and fat burning is compromised, it can be difficult to sleep through the night.

Ashwagandha has been shown in a number of studies to support blood sugar and lipid or fat levels already within normal range.5

  1. Toxic Brain Effect

With four billion pounds of toxins dumped into the American environment each year, it is important that we keep our natural detoxification pathways healthy. As environmental toxins are fat soluble, many of them find their way into the brain, where they congest brain lymphatics that drain toxins during sleep. Poor brain lymph drainage is linked to poor sleep, and poor sleep is linked to poor brain lymphatic drainage.

One study showed that glycowithanolide, a bioactive constituent of ashwagandha, induced an antioxidant effect in the brain and liver, which triggered a natural protective effect against heavy metal damage, shielding the body’s main blood- and lymph-cleansing organ.6

  1. Fat-Burning Effect

Perhaps the most effective way to support healthy sleep is to optimize the body’s ability to burn fat. Fat is a slow burning fuel, required to provide long-lasting fuel reserves to sleep deeply through an entire night. One of the best measures of fat metabolism is the ability to lose weight or burn fat naturally. Studies suggest that ashwagandha supports healthy weight while under heavy stress.

In one study, 52 overweight adults were given ashwagandha or a placebo for eight weeks. At four and eight weeks, they gave the subjects the Perceived Stress Scale, Food Cravings Questionnaire, Oxford Happiness Questionnaire, and Three-Factor Eating Questionnaire, as well as measuring serum cortisol, body weight, and body mass index.

The study showed positive outcomes on all counts, suggesting that ashwagandha root can be effectively used to combat stress and cravings, support mood and happiness, and support healthy body weight management in adults under heavy stress.7
