2 Key Concepts
Core Body Temperature Drop for Sleep
When you fall asleep, your core body temperature naturally decreases. Activities like taking a hot shower or bath right before bed can elevate your core temperature, creating a competing signal that may hinder the natural cooling process needed for sleep onset and quality.
Pre-Sleep Snack Strategy
To manage late-night hunger without disrupting sleep, a strategic pre-sleep snack should consist of approximately 50% complex carbohydrates and 50% lean protein. This combination provides slow-digesting fuel that can sustain you through the night, preventing hunger from waking you up.
4 Questions Answered
If you are accustomed to it and it helps you relax, it is generally fine. However, avoid having the TV on with bright light exposure in the hour before bedtime, as it can be psychologically stimulating.
A cooler temperature, specifically between 60 to 67 degrees Fahrenheit (16 to 20 degrees Celsius), has been shown to help individuals fall and stay asleep.
It is encouraged to shift the timing of a hot shower or bath to about an hour and a half before you plan to go to bed. Taking one right before bed increases your core temperature, which conflicts with the natural drop needed for sleep, potentially hindering deep sleep and muscle recovery.
Opt for a pre-sleep snack that is about 50% complex carbohydrate and 50% lean protein, such as whole-grain cereal with milk, cottage cheese with fruit, whole wheat crackers with peanut butter, nuts, or yogurt with fruit. These options are slow-digesting and can sustain you through the night without causing sleep disruption.
8 Actionable Insights
1. Optimize Sleep Temperature Gradually
Gradually lower your bedroom temperature by 1-2 degrees every couple of days to find your optimal cool setting, ideally between 60-67°F, which is conducive to falling and staying asleep.
2. Time Hot Showers/Baths Earlier
Shift hot showers or baths to 1.5 to 2 hours before bedtime, as this timing allows your core body temperature to drop, aiding in faster sleep onset and enhanced deep sleep.
3. Choose Smart Pre-Sleep Snacks
If hungry before bed, opt for a small snack combining complex carbohydrates and lean protein, such as whole-grain cereal with milk, cottage cheese with fruit, or nuts, to prevent hunger-induced awakenings and provide slow-digesting fuel.
4. Avoid Heavy Meals Before Bed
Refrain from consuming large, fried, fatty, or heavy meals in the hour directly before bedtime, as these can disrupt your sleep quality.
5. Utilize White Noise for Sounds
Employ white noise machines, especially adaptive ones, to mask uncontrollable external noises like construction or traffic, which can help you maintain sleep throughout the night.
6. Dampen Noise with Earplugs
Use earplugs, particularly when traveling or at home, to effectively dampen external noise and improve sleep continuity.
7. Mind Pre-Sleep Audio Choices
If accustomed to sleeping with sound, continue using a relaxing radio or podcast, but avoid bright TV screens in the hour before bed due to their stimulating light and psychological effects.
8. Regulate Bed Temperature for Partners
Consider using mattress covers that allow for individual temperature regulation, accommodating different preferences between bed partners for a more comfortable sleep environment.

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.
