2. Get Yourself A Good Pillow
A good medium-firm pillow that properly supports the head has been found to improve the quality of sleep significantly. Keeping a clean pillow is also important, a pillow that’s not clean could contribute to allergy-related impairment when it comes to breathing properly (down pillows and dust mites being the main offender). Tossing your pillow into the dryer once every couple of months will kill dust mites.
