Be sure to make the transition gradually. This goes out to the freshman especially as they have never gone through this before. I remember the first time I came home after college, I slept for 15 hours and was in the worst physical shape I had ever been. I ended up getting pretty sick for a few days too. Be sure to get your rest, but set an alarm so you do not over sleep or you will have no energy the next day. Getting your body used to drastically different sleep schedules doesn’t happen overnight (I know, I know, I’m sorry but I had to).
This gradual transition tip also goes for caffeine. Going from a constant IV drip of caffeine to none at all can leave you with mild to severe headaches, insomnia or exhaustion, irritability, constipation, lack of concentration, etc. Tone down your caffeine once you get home and get back on your home schedule, but do not cut it out completely. Reduce your intake and form of intake. For instance, if you were drinking energy drinks, try having a small amount of coffee the next day for caffeine, then black tea, then white tea. Some are more sensitive than others to caffeine shifts; be sure to listen to your body.
If you travel far for school, you may even feel a bit of culture shock when going back home for a few months. Try to do some things at home that you would have normally done at school. Keeping a similar schedule. Work out the same time you would if you were at school. Simply staying busy can be a good idea. You may end up feeling restless or bored, feeling stuck at home instead of living the exciting college lifestyle. In college, you are surrounded by people. If you go home to the suburbs or a rural area, you may feel a bit isolated at times. Be sure to stay busy catching up with family and friends not just getting right into your summer work schedule (if you have one). Keeping in touch with friends from school can be good too, but be sure to live in the present and interact with the people who are physically around you.
Having things to look forward to in this regard can do you some good. Getting a couple friends together for a road trip, sports game, or concert can be just the thing you need to get through the hours at a boring summer job.
If you do find yourself with a day completely free and bored, remember that it was only a few weeks ago that you were stressed out beyond belief, and there weren’t enough hours in the day. Enjoy the days when you’ve got nothing to do since before you know it, you will be a graduate and enter the real world where there are no summers when you’re completely off.
