If you’ve ever felt the sand man come over you at work, you’re not alone. Around 1pm in the afternoon, a lot of people start to feel that midday slumber come over them. There are ways you can reenergize yourself. One idea in particular is to spend at least 10 minutes outside twice a day.

Getting fresh air and sunlight will help to create a positive hormone response that increases energy.

This works because the longer you’re indoors, the more melatonin is produced, which increases your desire to sleep.
