Sleep-Weight Connection

Researchers at Northwestern University have found a link between eating and sleeping that can in fact affect your weight. Since the 1960s, the average amount of sleep American adults get has dropped from 8.5 hours to less than 7 hours per night. A similar pattern is occurring for young adults. As of 2004, only 23.5% of young adults are getting 8 hours of sleep per night.

Participants in the study who slept for four hours a night on two consecutive nights showed an 18% increase in appetite, especially for high fat and carbohydrate snacks. The study suggests that sleep deprivation alters the hunger-regulating hormones in your body (increasing ghrelin, the hunger hormone, and decreasing leptin, the satiety hormone). This leads to an increased appetite with a preference for high fat, high calorie and sugar-containing foods. Thus, an adequate amount of sleep is an essential part of a healthy lifestyle and for weight maintenance.

If you are losing sleep due to feelings of negative thoughts or anxiety, increasing the amount of serotonin in your body may help improve your mood and promote better sleeping patterns. Serotonin is a hormone in the brain that acts as a chemical messenger that transmits nerve signals between nerve cells. Changes in the serotonin levels in the brain can alter mood.

Here are some natural ways to increase serotonin:

• Catch some rays! Research indicates that serotonin levels increase when the sun is shining. Ever wonder why you crave carbohydrates at the end of the day? When the sun goes down, so do your serotonin levels. Consider exposing yourself to sunlight in the late afternoon, or use light therapy to boost your serotonin and leave you feeling refreshed and more energized.
• Smile! Serotonin is part of positive chemistry so when you put yourself in a joyful situation with good thoughts, your serotonin levels increase. Smile when walking past a stranger or find something good in your day to give yourself a boost!
• Get moving! Exercise increases both endorphins (“feel good hormones”) and serotonin levels in our bodies due to the increase in the amount of oxygen we use when engaging in physical activity. While you want to aim for 30-60 minutes of exercise most days of the week, even as little as 20 minutes can enhance your mood.
• Socialize! Getting together with a close friend or relative can help you feel bonded, which in turn increases serotonin levels. Research suggests that feeling a bond with another individual decreases negative emotions (such as fear or anxiety) and thus naturally increases serotonin production.

Additional Tips for Getting a Good Night’s Sleep 

• Take a warm bath prior to bedtime.
• Improve your sleep environment. Select a comfortable mattress, pillow, sheets, and clothing, and keep the room temperature moderate or cool.
• Improve sleep hygiene by developing a pre-bedtime routine and follow it regularly. This will help signal your body that it’s time to sleep.
• Try to get to bed around the same time each night.
• Make yourself a cup of warm herbal tea (i.e. Chamomile) or warm milk, and read until you feel drowsy.
