00:02 When it comes to sleeping conditions,
00:06 some like it hot, others prefer cooler and even cold.
00:10 But the debate isn't just a relationship disagreement.
00:13 Sleep psychologist, Dr. Michelle Dreerup says,
00:16 room temperature can disrupt sleep,
00:18 which can affect health and cognitive functioning.
00:20 - For most people, the ideal range
00:23 is having the thermostat set between 60 to 67 degrees
00:28 Fahrenheit for the most comfortable sleep.
00:30 - People vary within that range,
00:32 so it's important to figure out what your body prefers.
00:34 Sleeping too hot or too cold can affect a good night's rest.
00:38 - So 65 is kind of, you know,
00:40 kind of the number that's given.
00:42 Really anything over 70 is too toasty and hot.
00:47 - Think of your bedroom as your cave.
00:49 It should be cool, dark, and quiet.
00:51 - The temperature, I think people tend to have
00:55 more difficulties with the heat,
00:56 and maybe it's because that they're not able
00:58 to self-regulate that temperature as much.
01:02 - Thermoregulation is important for staying
01:04 in the restorative slow-wave sleep stage.
01:07 - Our brain activity is very slow during that time.
01:10 That's where a lot of physical restoration is occurring.
01:14 - If your bedroom is above 70 degrees Fahrenheit,
01:16 it's too hot.
01:17 - Higher temperatures or warmer temperatures
01:20 can cause decreased slow-wave sleep
01:23 and poor quality sleep.
01:26 - While sleeping too cold may not affect
01:28 sleep cycles as much,
01:29 it can cause your body to kick into high gear to get warm
01:33 if your bedroom temperature is lower
01:34 than 60 degrees Fahrenheit.
01:36 It's too cold.
01:37 Dr. Drew up advises couples who disagree over temperature
01:40 to keep the room on the cooler side
01:42 and have extra blankets handy.
01:44 - I can take off a layer, right?
01:46 And then it can be, you know, if I have a bed partner,
01:49 even if the house is too cold for me,
01:51 I can put on another layer of a blanket
01:55 or comforter to stay warm.
01:57 - Keeping a fan in your room is a quick way to cool down
02:00 if warm.
02:01 Avoid drinking caffeine or foods high in sugar near bedtime.
02:05 They can increase your body temperature
02:07 and sleep for the season with the right pajamas,
02:09 bed sheets, and blankets.
