When You Sleep Less Than Six Hours a Night

Sleep and Reproductive Health

Sleep deprivation can disrupt hormonal balance, particularly in women. Studies show that insufficient sleep may increase thyroid-stimulating hormone (TSH) levels, which can interfere with reproductive function.

These hormonal shifts have been linked to menstrual irregularities, missed ovulation, absent periods, and even recurrent miscarriages. While sleep may not be the sole factor, maintaining consistent, adequate rest supports hormonal stability and overall reproductive wellness.
Weight, Focus, and Everyday Performance

The effects of poor sleep extend far beyond feeling tired. Chronic sleep loss can lead to:

Reduced concentration and slower reaction times
Lower productivity and impaired decision-making
Increased irritability and mood swings

Sleep deprivation also affects metabolism and hunger-regulating hormones, increasing cravings and raising the risk of weight gain. When sleep becomes a priority, the body gains time to repair tissues, regulate appetite, and support cognitive performance.
