I'm someone that tells myself that I sleep with something playing. I grew up with a radio in my room, so as an adult now I'm always looking to play something as I fall asleep. Is that going to hurt my sleep quality? I would say if you're accustomed to this, I would say that's fine to continue to do so. I am not a fan of having the TV on and having the bright light exposed to you in that hour before bedtime, because it also can just be very psychologically stimulating. But if, like you said, it's a radio or it's a podcast that you feel is helping you relax, then I'm a fan of it.

Do you think diuretica will help people relax? It might. It might help you at least think about your sleep a bit more and challenge you to do maybe one change tonight. We consider that to be a scientific endorsement of the podcast. Okay, so I've got sound down. You are a fan of the white noise machines. I am because sometimes there's external noises like a garbage truck or construction that you're not always able to control. So if you can at least mask over it temporarily, that

can sometimes be helpful to keep individuals more asleep during the nighttime. And there's even some now that are adaptive. So if the door slams, then the volume temporarily increases and then will decrease. So there's almost these smart white noise machines that are coming out on the market. So that's from a noise standpoint.

And earplugs are going to be helpful if you're traveling. When you're at home, you can obviously use those to dampen down any external noise. From a, from a temperature standpoint, you want it to be cool. I think this is an area that a lot of people can benefit from because they often sleep in much warmer temperatures than what we know is probably more conducive to sleep, which is cooler.

60 to 67 degrees has been shown to help individuals stay asleep and fall asleep. That may be frigidly cold for some, but you have to find the temperature that's right for you. I would say decrease your temperature by say one degree or two degrees every couple of days, and then you can find the temperature that works well for you. And there's even technology now where there's mattress covers that can help you regulate temperature from much cooler to warmer so if there's differences in bed partners that's a way that you can actually accommodate both of their preferences. So that's about 16 to 20 degrees Celsius. What about when I shower or I bath because often I go and

have a shower then I get straight into bed after. Yes. Is that good or bad? I would encourage you to shift that timing a little bit earlier into the night so I go and have a shower, then I get straight into bed after. Yes. Is that good or bad? I would encourage you to shift that timing a little bit earlier into the night. So an hour and a half before you are planning to go to bed, I would shift your shower. Because when you are taking a hot bath or hot shower, it increases your core temperature.

But when you fall asleep, your core temperature drops. So you don't want that competing signal to be right before bedtime. But if you back that shower up an hour and a half, that should be sufficient time that we think potentially there's an augmentation of helping that drop in temperature. And some smaller studies have shown that that can help decrease the time to fall asleep and also enhance deep sleep, which has implications for muscle recovery, regeneration, and you get more of that in the earlier part of your night. So it's an easy fix just to tweak the timing of your shower and your

hot bath to be just an hour or two before bedtime, not right before bed. So it's a strategy too if you have difficulties winding down and relaxing to implement that hot shower, hot bath earlier in the evening. One of the problems I also have when I sleep sometimes is I hear people say you can't eat like three or four hours before bed. However, I sometimes get home at 10 p.m. and I get hungry as hell at 10 p.m.

And then sometimes if I order food, for example, it might come at like 11. Which means that I end up eating at 11. And then I really see it in my sleep scores. I think as well that I'm someone that tends to fall asleep later. Again, this might just be me telling BS to myself, but that's what tends to happen. And I know I'm not supposed to eat before bed, but I'm so hungry. So is there anything that I can eat before bed that won't disrupt my sleep, but will get rid of the hunger?

Yes, the preference is not to have a huge meal right before bed that's fried, fatty, you know, really heavy sitting in your stomach that hour right before bedtime. So if you're able to time them, be strategic, then that's obviously the preference. But I'm okay with you having a pre-sleep snack. A lot of times for my athletes, right before bedtime. So if you're able to time them be strategic, then that's obviously the preference. But I'm okay with you having a pre-sleep snack.

A lot of times for my athletes, that means we'll go for something like 50% of a complex carb and like 50% of a lean protein. So for example, cereal and milk is an easy one. Cereal. Yes, cereal and milk. Of course we want something that's whole grain and not necessarily a sugary cereal,

but cereal and milk is an easy one that many people have access to, or cottage cheese and fruit or 100% whole wheat crackers and peanut butter. And the reason why is because I don't want you waking up in the middle of the night being hungry or even trying to fall asleep and you feel like you're hungry. But we want something that's slow digesting through the night, because ideally you're going to be sleeping seven, eight, nine hours during the night. And we want it to be able to get you to the morning time and then you will fuel when you wake up. So a pre-sleep snack can be a great strategy if you're coming home late and

you want to obviously be able to fuel before bed, or if you have a really early dinner and you're hungry before bedtime. Yeah, that happens sometimes as well. Sometimes I'll eat dinner at about 5 pm. Yep. And then I get to about 10, 11 pm and I'm still awake and I'm starving. Okay, so what's a pre-sleep snack that you think you can grab for? Some nuts. Okay, yeah.

Does that work? Yeah, yeah. Nuts have protein in them. Yeah, you can grab a good nut mix. Maybe you can partner that also with like some yogurt too. Raspberries. Raspberries? Yeah, you can grab a good nut mix. Maybe you can partner that also with like some yogurt too. Raspberries. Raspberries. Yeah, fruit. Yeah, and some, yes, a protein and carbon there. And those are good, good pre-sleep snack.
