It is self-evident that sleep is important but the cost of sleepless nights goes far beyond feeling grouchy the next day.
Regular poor sleep puts you at risk of serious medical conditions, including obesity, heart disease and diabetes – and it shortens your life expectancy.
It is therefore imperative to make sure you get the recommended amount of sleep each night to ensure a long and healthy life.
Participants who took three grams of glycine before bedtime showed improved objective measures of sleep quality compared to the placebo and glycine supplements also helped participants fall asleep faster.
Glycine can also be found in a number of foods such as bone broth, meat, eggs, poultry, fish, beans, spinach, kale, cabbage and fruits like bananas and kiwis.
One potential explanation lies in glycine’s ability to stimulate and inhibit cells in the brain and central nervous system, affecting cognition, mood, appetite and digestion, immune function, pain perception, and sleep, according to the Sleep Doctor.
Glycine is also involved in the production of other biochemicals that influence these body functions, the website says.
You should also make sure your bedroom is sleep-friendly to promote a good night’s sleep.
The NHS explains: “Your bedroom should be a relaxing environment. Experts claim there’s a strong association in people’s minds between sleep and the bedroom.”
However, as the health site notes, certain things weaken that association, such as TVs and other electronic gadgets, light, noise, and a bad mattress or bed.
“Keep your bedroom just for sleep and sex (or masturbation). Unlike most vigorous physical activity, sex makes us sleepy. This has evolved in humans over thousands of years,” it advises.
