You have to do a google search for "Pubmed", which is the U.S. government medical database. Search "Light Therapy SAD". The SAD is seasonal affective disorder. There are dozens of actual double-blind studies providing details of the protocols and outcomes.
Light therapy does not work unless the exposure is for at least thirty minutes at a specified time every day and preferably at least 45 minutes.
Thank you for your tips. He has been seen by a few psychologists over the years, but not a psychiatrist maybe they would be more helpful.
I was going to recommend the same thing, sounds like he's suffering from SAD.
IN the meantime, here's a list of sleep tips I've comprised, as I've pretty much been an insomniac my entire adult life. If a person REALLY makes a concerted effort to do these things consistently, it DOES really help! Definitely recommend to him that he should be seen by another psychiatrist though, for further treatment.
Here are some tips to help with your sleep:
1. Avoid any and all stimulants (caffeine, nicotine, energy drinks, etc) as much as possible, especially within 4+ hours of bedtime.
2. Exercise is a great way to induce sleep, as it releases natural endorphins. Even a brisk evening walk will help. Your exercise should be an hour or more before your bedtime..you don't want to exercise right before bed.
3. Try to avoid eating a heavy meal close to bedtime. If you're hungry, stick to a light snack an hour or more before bed. Avoid ALL fluids 3 (or more if you can) hours before bed. Nothing worse than finally getting to bed and have mother nature wake you up!
4. Stick to a consistent bedtime and a consistent bedtime routine. Even on days when you don't FEEL tired at your bedtime, try to stick to your routine...that conditions your body and brain. Pick a reasonable time. If you work 3-11:30 and get home at 12, a reasonable time isn't 12:30, as you would need time to unwind after getting home.
5. Create an environment conducive to sleep and relaxation. Your bedroom and bed should be an inviting place that you look forward to retiring to. Keep the room clean and clutter free, keep dust levels down. Keep your bedding washed with clean or fresh smelling scents. Choose comfy, non-binding clean smelling PJs. ALL of our 5 senses affect our mood, and also our sleep. If you have a quiet room, but your sheets smell like feet (lol), that won't be very relaxing. Keep the room DARK. Keep weather in mind. In the summer, you would only need a light sheet or blanket, in the winter, heavier blankets are necessary to keep you comfy. Again, back to the senses...if you create a bed that keeps you too hot or too cold, that will interfere with your sleep. Keep a glass or bottle of water at your bedside, in case you awaken with that dry mouth and need for a drink. This way you don't have to get out of bed to get something to drink. Light soothing music or white noise machines for LOW (not blaring) background noise can be helpful. Try to avoid using TV as a background noise, as our brains are still working while asleep, and the things you hear from the TV could affect your anxiety levels and even dreams. Basically, sleeping with sounds of "The Chainsaw Massacre" in the background won't lead to happy thoughts. ;0) A warm bath or shower is great before bed...dry your hair. Never go to bed with wet hair. NOT comfy!
6. Ignore the urge to get out of bed. Even when you're feeling frustrated, try to remain in bed, reposition yourself, adjust your sheets, read a book if you are not falling asleep, but the more up and down you do, the harder it is to get and stay asleep it is. The same goes for nighttime awakening. If you DO fall asleep and wake up in the middle of the night, ignore the urge to get out of bed...again, reposition yourself, adjust the sheets, and try to go back to sleep. When you get up out of bed, you're waking yourself more. If you stay lying in bed, you are not as awake. If nature calls...go to the BR, and get right back to bed..no snacking, no smoke breaks (I'm bad at this...lol). Those things are murder for sleep. Get up...go potty, right back to bed.
7. When you DO manage to finally start on a consistent routine, you'll find things that help and hurt your sleep. Take note of them and adjust your regimen as needed. Sleep patterns will change, and life happens, so sometimes, adjustments need to be made. Consistency is TRULY the key..I cannot stress that enough.
8. Listen to your body. For a while, while your sleep is lousy, you will feel tired at odd times of the day. Your body is telling you it needs rest, so heed the wanring...take a nap. Lie down on the sofa, and catch a 1 hour (or less) nap. Don't nap for hours at a time, that will interfere with your nighttime sleep. An hour is the perfect amount of time for a refresher. Also, don't nap in bed. Once you're conditioned, your bed should be for nighttime sleeping only.
Hope these tips help some...I know these are the things I do that help me get some decent sleep. It's not always foolproof, but it works pretty well. If you are going days without any sleep, definitely see your doctor. Sleep depivation is a whole other ballgame, it can be dangerous.
Thank you for your response. He did try the box light a number of years ago, but maybe he should try it again.
S.A.D.
Seasonal Affective Disorder
It sounds like this. I have it. I get more depressed, anxious, and fatigued in the months with less sun. I have had to go to a few therapists for it. It's also hereditary (as most things are). Try asking a Dr for information about it.
He could probably benefit from light-therapy, which is relatively inexpensive. Do a google search. It involves exposing the eyes to a variety of light wavelengths in the morning for at least thirty minutes.
