If you\u2019re a skincare junkie, chances are you\u2019ve introduced peptides into your daily routine. But did you know they\u2019re buzzing around the world of sleep too?<\/p>\n\n\n\n
\u201cCertain peptides help regulate your internal clock<\/a>, influence sleep-wake cycles, and interact with systems involved in stress, hormones, and recovery,\u201d says Greg Jones<\/a>, board-certified naturopathic physician and founder and medical director of Enovative Wellness Center<\/a>.<\/p>\n\n\n\n But what is the connection between peptides and sleep, exactly? Ahead, we\u2019re breaking down everything you need to know about peptides and their impact on how you get your beauty rest.<\/p>\n\n\n\n Let\u2019s start by discussing what peptides actually are. Basically, these tiny chains of amino acids are the building blocks which make up proteins. <\/p>\n\n\n\n \u201cThese little messengers in the body act as signaling molecules, helping signal cells perform specific functions,\u201d explains Jones. <\/p>\n\n\n\n He adds that different peptides can help with hormone release, inflammation, tissue repair, and immune responses.<\/p>\n\n\n\n There are a lot of different peptides, and some are more commonly known than others. For example, you may have heard of insulin, oxytocin, or endorphins. <\/p>\n\n\n\n And, while we\u2019re focusing on sleep specifically here, it\u2019s worth noting that within the skincare world, they can help strengthen elastin and collagen<\/a>, which can help reduce the appearance of fine lines and wrinkles, dullness, or crepey skin. (Not too shabby, right?)<\/p>\n\n\n\n Jones stresses that peptides aren\u2019t all the same. <\/p>\n\n\n\n While some are well-established medications that can help people with specific medical issues, \u201cmany of the peptides marketed online have limited evidence supporting their benefits,\u201d he says.<\/p>\n\n\n\n \u201cYour body is constantly sending signals to help regulate when you feel awake and when you feel sleepy,\u201d says Jones. <\/p>\n\n\n\n Peptides can work their way into this process because of their ability to act as signaling molecules\u2014so they may be used to do the following:<\/p>\n\n\n\n One such peptide is orexin, which helps stabilize the transition between sleep and waking up. <\/p>\n\n\n\n When orexin signals are strong, it stimulates the production of dopamine<\/a>, which pretty much is the exact opposite of what you want when you\u2019re trying to get your beloved eight hours of sleep.<\/p>\n\n\n\n Jones says that since \u201cthe science varies significantly depending on the specific peptide,\u201d it\u2019s important to understand which peptides actually work for sleep and recovery. <\/p>\n\n\n\n \u201cMany marketed for sleep or recovery still lack strong human evidence establishing their safety and effectiveness,\u201d he explains.<\/p>\n\n\n\n \u201cPeptides are getting a lot of attention in the sleep and recovery world,\u201d says Jones. He specifically calls out the following peptides in relation to sleep:<\/p>\n\n\n\n CJC-1295 is especially interesting in regards to sleep since Jones says that \u201cgrowth hormone is released primarily during deep slow-wave (non-REM) sleep and simultaneously deep sleep<\/a> promotes growth hormone release.\u201d <\/p>\n\n\n\n What does this mean? In a study by University of California, Berkeley<\/a>, it was found that this growth hormone helps build muscle and bone and reduce fat, while a brainstem feedback mechanism helps promote wakefulness after a good night\u2019s sleep.<\/p>\n\n\n\n The short answer? Maybe, maybe not. While peptides are buzzy, they might not actually do much for your overall sleep habits\u2014and could even be harmful. And while some peptides signal the brain to rest or release growth hormones, they shouldn\u2019t be used as quick-fix sleeping pills.<\/p>\n\n\n\n Jones stresses that not only are they not<\/em> established sleep aids<\/a>, but \u201cthere\u2019s limited high-quality evidence showing that they safely improve sleep quality or treat insomnia,\u201d he says. <\/p>\n\n\n\n He also cautions against peptide supplements sold online, since he says they may have \u201cquestionable purity, dosing accuracy, or contamination risks.\u201d<\/p>\n\n\n\n His biggest concern is where peptide supplements are sourced. <\/p>\n\n\n\n \u201cAlmost all peptides people buy online are sold as \u2018research use only\u2019 chemicals, without oversight of purity, potency, or sterility,\u201d he says, cautioning that independent testing can lead to mislabeling or contamination.<\/p>\n\n\n\n Instead of relying on peptides you buy blindly, Jones says you should work with a clinician\u2014and, even then, they influence so many things in the body that it might still be dicey. <\/p>\n\n\n\n \u201cPeptides are still potent signaling molecules,\u201d he says. \u201cThey can influence hormones, blood sugar, and immune function. That’s why they belong inside a supervised medical relationship with proper screening and monitoring, not in an online shopping cart.\u201d<\/p>\n\n\n\n The bottom line? Before you start taking peptides and introducing them into your sleep routine, make sure you consult your doctor to see if they\u2019re right for you.<\/p>\n\n\n\n Wondering how to get your Z\u2019s without using peptides? Jones has some simple tips and tricks for you.<\/p>\n\n\n\n Maybe. While peptides can be beneficial for sleep, they aren\u2019t a one-size-fits-all solution. And since many of the peptides sold online may be labeled wrong or contaminated, they can actually end up being more harmful than helpful. Before you start using peptides, you should speak with your doctor to find out if they\u2019re right for you.<\/p>\n\n\n\n Some specific peptides can help increase the time you spend in deep sleep (aka slow-wave sleep). This is because they can help stimulate the release of growth hormones, reduce stress or neural arousal, and regulate circadian rhythms.<\/p>\n\n\n\nWhat are peptides?<\/h2>\n\n\n\n
