From sleepovers to vacations, we've all probably been away from home at some point of time. A lot of people have different things to say about the sleep quality during such times. Many report being unable to sleep, some sleep better, and a considerable few state no difference at all.
If you frequently spend nights away from home in a different city, especially due to your job, your body might get used to the change in the diurnal clock. In fact, if you stay at a particular hotel, it would be easier for you to adjust.
You can even request for a comfortable room, away from the elevator and noise, away from street lights, with black-out curtains, and the like. But if not, remember that there are innumerable ways to get a good night's sleep away from home.
If you're homesick at a sleepover, make your friend's room a little more familiar, like your own bedroom. The familiarity will relax your mind and lull you to sleep.
Any disruption from this routine confuses the brain, which is why you must stick to the same schedule - this will help in overcoming the phobia of not being able to sleep away from home.
But it is likely to force the brain to concentrate and think, resulting in tiredness and drowsiness. So listen to some soft music or watch an interesting movie; you might be able to get better sleep.
So, take a familiar scent along with you - a perfume, talcum powder, fresh parchment, etc. Or, you can try lavender, the best of all. It'll relax your mind, calm your frayed nerves, and help increase the frequency of SWS (slow-wave sleep) - the period of restorative sleep.
However, people believe that drinking chamomile tea, peppermint tea, valerian root, milk, etc., may help increase glycine, which in turn acts as a mild sedative to calm the nerves and induce sleep.
Meditation, yoga, etc., are some great methods that are likely to relax your mind and help you from overthinking. Again, this has no scientific backing; experts simply believe that a relaxed mind results in better sleep.
If any of these activities relaxes you and lulls you to sleep, do so, but stop an hour before sleeping. This way, the body is tired, and a part of the brain is tired too, and you might be able to sleep. Never forget though, while the body sleeps, the brain is always active.
