Sleep is one of the most beneficial and important things for the human body, but there are some important things you should avoid to get the best sleep possible.
Professor Russell Foster, a world-renowned expert on circadian rhythms, says he has provided a simple checklist to follow to help you sleep better. daily mail.
Late night cravings for a snack or even a meal before bed are one of the worst things that can happen to your body.
Professor Foster claimed that eating a large meal could raise your core body temperature, making it harder to fall asleep.
Everything about sleep is produced by a natural process called circadian rhythms, which repeat in your body approximately every 24 hours.
If the body's circadian rhythm is active, a drop in core body temperature is formed before a person falls asleep.
“If the food is spicy and especially rich, the increase in body temperature is even worse,” he says.
Another thing on Foster's list is avoiding late-night exercise, which also has implications for body temperature levels.
Exercise is thought to be an intense activity that raises your body temperature, making it harder to fall asleep.
Elsewhere, Foster emphasizes avoiding phone use before bedtime, as it is correlated with stimulating certain areas of the brain.
Natural light generally plays a vital role in the sleep-wake cycle and affects melatonin levels, so high levels of artificial light have a big impact on your body before bed.

“I think it's certainly a good rule of thumb to minimize light exposure, but you don't have to stick to it,” Foster says.
Foster says using a phone before bedtime makes it difficult for people to relax and unwind because the device causes an “alert” to the brain.
“Most people don't have sleep problems; they have stress and anxiety problems,” Foster said.
“So many people use their smartphones as alarm clocks, so when you wake up in the middle of the night, it's naturally easy to get sucked into all the distractions.”
Last but not least, Foster emphasizes the importance of avoiding caffeinated and alcoholic drinks.
Alcohol may be known to help you fall asleep, but Foster says it actually interrupts the rapid eye movement (REM) phase of sleep.
Sleep gurus say that drinking too much alcohol to the point of falling asleep disrupts some of the most “important things going on in your brain.”
“Chronic alcoholics are notorious for having poor sleep and have significant problems with memory loss and memory processing,” he added.
When it comes to coffee, it's clearly a no-no.
This drink causes sleep problems due to increased levels of caffeine, which is similar to a chemical called adenosine, which is an inhibitory neurotransmitter that helps signal pathways and various functions in the body to promote sleep.
Caffeine is structurally similar to adenosine, so it fits snugly into adenosine receptors, blocking the chemical and making you more alert.
“The problem is, you can wake up all day feeling full of caffeine,” Foster points out.
“Drinking it later in the day increases what's called a half-life. Both can still be hanging around for five or nine hours at high concentrations.”
