2. Eating spicy food just before bedtime
Imagine the countless nights waking up with a burning chest pain and taking Gaviscon, etc?
3. Eating sweets and desserts full of sugar
Sleep is like your car being in a garage with the engine turned on and humming without moving. Eating sweets, etc, is like putting high-octane fuel in a resting vehicle, making the engine speed up and warm up at night time instead of cooling down
4. Snaking before bedtime
This is like putting more heavy stuff in the back of the bonnet of the car at night time, so not letting it rest and overloading the system
5. Having alcohol just before bedtime
Your sleep is like a carefully conducted symphony with different instruments (sleep stages). Alcohol is like a disruptive guest who barges in and starts banging on the drums loudly and erratically. At first, it might make the music seem slower and more relaxed (you feel sleepy), but soon it throws off the rhythm and harmony, causing the symphony to fall apart (fragmented, poor-quality sleep).
