If you tend to wake up during the night, do this every hour during the day for 5 minutes, and right before bed: Flex your feet up and down as if you’re stepping on a gas pedal. The journal Respiratory Physiology & Neurobiology says that’ll keep fluid from building up in your legs, which spreads through your body when you lie down at night. That puts pressure on your airway, and can lead to labored breathing during sleep, which can cause micro-arousals throughout the night. So, pump your feet for 5 minutes after every hour of sitting. You’ll stop the fluid buildup, breathe easier at night, and sleep better.
