Effects of Sleep on Physical Health

We all know sleep is important, but do you know why?

In a study done by Erin C. Hanlon, PhD, Research Assistant Professor at the University of Chicago, Dr. Hanlon stated that sleep-deprived study participants had higher levels of chemical signals that can make high-fat, high-calorie foods more pleasurable than when not sleep-deprived and that following sleep deprivation, subjects ate nearly twice as many carbohydrates and fat. This begs the question, what else does sleep affect?

Poor sleep can cause increased risk of falls or injuries, heart problems and metabolic issues like diabetes. Poor sleep can also decrease immune function leading to:

• Increased risk of infection and inflammation
• Increased chances of getting a cold and flu
• Increased risk of developing or worsening depression
• Increased risk of cancer from inflammation

Good quality and quantity of sleep can:

• Help repair, grow and rejuvenate the body
• Help the brain clear cellular and protein debris (decreasing buildup that can cause damage leading to inflammation and cell death)
• Speed recovery from illness and reduced allergic reactions
• Help create more efficient response to vaccines
• Assist memory consolidation
• Improve mental health

Practicing good sleep hygiene will give you a jump start. Try these tips:

• Establish a bedtime routine
• Limit electronic devices before bed
• Keep the bedroom dark and cold
• Keep the same sleep schedule
