Many people do not realize how connected exercise is to sleep habits. Studies have shown that regularly exercising leads to better and more consistent sleep. However, exercising intensely or sporadically right before bed could lead to sleep deprivation or insomnia. If you do any exercise before sleep, make sure it is low intensity like stretching or yoga.

Cuddling, hugging, or any physical contact with another person has been shown to reduce stress and blood pressure because it boosts oxytocin--the 'love' hormone.

If you weren't convinced by the 'love' hormone, sharing your bed with a partner can reduce inflammation, too! This happens through a reduction in cytokines.

Know any tired single women? Research has proven that women in serious relationships wake up less frequently throughout the night and fall asleep faster than single women or women in inconsistent relationships.
