Have a question or a request? We love to hear from you!

In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

So, no question/request too big or small 😎

❝I’m one of those older folks that have a hard time getting 7 hrs. I know a lot of it my fault…like a few beers at nite…🥰am now trying THC gummies for anxiety, instead of alcohol……less calories 😁how does THC affect our sleep,? Safer than alcohol…..I know your next article 😊😊😊😊❣️😊alot of us older kids do take gummies 😲😲😲thank you❞

Great question! We wrote a little about CBD gummies (not THC) before:

Do CBD Gummies Work?

…and went on to explore THC’s health benefits and risks here:

Cannabis Myths vs Reality

For starters, let’s go ahead and say: you’re right that it’s safer (for most people) than alcohol—but that’s not a strong claim, because alcohol is very bad for pretty much everything, including sleep.

So how does THC measure up when it comes to sleep quality?

Good news: it affects the architecture of sleep in such a way that you will spend longer in deep sleep (delta wave activity), which means you get more restorative and restful sleep!

See also: Alpha, beta, theta: what are brain states and brain waves? And can we control them?

Bad news: it does so at the cost of reducing your REM sleep, which is also necessary for good brain health, and will cause cognitive impairment if you skip too much. Normally, if you are sleep-deprived, the brain will prioritize REM sleep at the cost of other kinds of sleep; it’s that important. However, if you are chemically impaired from getting healthy REM sleep, there’s not much your brain can do to save you from the effects of REM sleep loss.

See: Cannabis, Cannabinoids, and Sleep: a Review of the Literature

This is, by the way, a reason that THC gets prescribed for some sleep disorders, in cases where the initial sleep disruption was because of nightmares, as it will reduce those (along with any other dreams, as collateral damage):

One thing to be careful of if using THC as a sleep aid is that withdrawal may make your symptoms worse than they were to start with:

Updates in the use of cannabis for insomnia

With all that in mind, you might consider (if you haven’t already tried it) seeing whether CBD alone improves your sleep, as while it does also extend time in deep sleep, it doesn’t reduce REM nearly as much as THC does:

The effects of a brand-specific, hemp-derived cannabidiol product on physiological, biochemical, and psychometric outcomes in healthy adults: a double-blind, randomized clinical trial

👆 this study was paid for by the brand being tested, so do be aware of potential publication bias. That’s not to say the study is necessarily corrupt, and indeed it probably wasn’t, but rather, the publication of the results was dependent on the company paying for them (so hypothetically they could have pulled funding from any number of other research groups that didn’t get the results they wanted, leaving this one to be the only one published). That being said, the study is interesting, which is why we’ve linked it, and it’s a good jumping-off-point for finding a lot of related papers, which you can see listed beneath it.

CBD also has other benefits of its own, even without THC:

❝Why do I get tired much more quickly running outside, than I do on the treadmill? Every time I get worn out quickly but at home I can go for much longer!❞

Short answer: the reason is Newton’s laws of motion.

In other words: on a treadmill, you need only maintain your position in space relative the the Earth while the treadmill moves beneath you, whereas on the road, you need to push against the Earth with sufficient force to move it relative to your body.

Illustrative thought experiment to make that clearer: if you were to stand on a treadmill with roller skates, and hold onto the bar with even just one finger, you would maintain your speed as far as the treadmill’s computer is concerned—whereas to maintain your speed on a flat road, you’d still need to push with your back foot every few yards or so.

More interesting answer: it’s a qualitatively different exercise (i.e. not just quantitively different). This is because of all that pushing you’re having to do on the road, while on a treadmill, the only pushing you have to do is just enough to counteract gravity (i.e. to keep you upright).

As such, both forms of running are a cardio exercise (because simply moving your legs quickly, even without having to apply much force, is still something that requires oxygenated blood feeding the muscles), but road-running adds an extra element of resistance exercise for the muscles of your lower body. Thus, road-running will enable you to build-maintain muscle much more than treadmill-running will.

Some extra things to bear in mind, however:

1) You can increase the resistance work for either form of running, by adding weight (such as by wearing a weight vest):

Weight Vests Against Osteoporosis: Do They Really Build Bone?

…and while road-running will still be the superior form of resistance work (for the reasons we outlined above), adding a weight vest will still be improving your stabilization muscles, just as it would if you were standing still while holding the weight up.

2) Stationary cycling does not have the same physics differences as stationary running. By this we mean: an exercise bike will require your muscles to do just as much pushing as they would on a road. This makes stationary cycling an excellent choice for high intensity resistance training (HIRT):

HIIT, But Make It HIRT

3) The best form of exercise is the one that you will actually do. Thus, when it’s raining sidewise outside, a treadmill inside will get exercise done better than no running at all. Similarly, a treadmill exercise session takes a lot less preparation (“switch it on”) than a running session outside (“get dressed appropriately for the weather, apply sunscreen if necessary, remember to bring water, etc etc”), and thus is also much more likely to actually occur. The ability to stop whenever one wants is also a reassuring factor that makes one much more likely to start. See for example:
