The Perfect Times of Day to Do Just About Everything

What's the perfect time of day to do, well, everything? Mental Floss has come up with precisely that list, grounding its calendar in physiological science. Following is a list of the best times of day to undertake various tasks, as well as the scientific explanation for why:

  • 7.a.m. Make a baby. Some studies say men's sperm counts are higher in the morning.
  • 8:30 a.m. Decide something. Researchers have found we make our best decisions right after we wake up.
  • 9:30 a.m. Update your blog. Many people check their favorite websites before 10 a.m.
  • 10 a.m. Take an aspirin. Mornings, particularly Mondays, are the most common times for both migraines and heart attacks.
  • 11 a.m. Send an email. Analysis of more than 200 million emails found that people are most likely to read their mail shortly before their lunch break. 
  • 1 p.m. Watch a funny YouTube video. Exhaustive analysis has shown that "the national mood" is lowest at 1 p.m., so cheer yourself up!
  • 2 p.m. Take a power nap. At around 2, your body temperature starts to drop the same way it does at night, and researchers have found that a 10-minute power nap is the most effective way of combating a mid-afternoon slump.
  • 4:30 p.m. Clean the house. It's best to clean when your hand-eye coordination is highest, which is between 4 and 5 p.m.
  • 5 p.m. Get some exercise. Your body temperature is highest from 5 to 6 p.m. The heat increases your stamina and strength, making your workouts more effective.
  • 9 p.m. Sell something on eBay. According to the site's experts, the best time to end an auction is 9 p.m.
  • 10 p.m. Solve the world's problems. Difficult problems require creative thinking, and studies show that people do their most abstract thinking when they are tired.
