Sleep and Hormones

[GavinParkPT]

Sleep and hormones are closely interconnected, with sleep playing a crucial role in regulating various hormones in the body. Here are some key points about how sleep affects hormones:

Melatonin: Produced by the pineal gland, melatonin helps regulate sleep-wake cycles. It signals to your body that it's time to sleep.

Cortisol: Known as the stress hormone, cortisol levels peak in the morning to help you wake up and decrease throughout the day. Poor sleep can disrupt this cycle, leading to elevated cortisol levels.

Growth Hormone: Released during deep sleep, growth hormone is essential for cell growth and repair.

Leptin and Ghrelin: These hormones regulate hunger. Leptin decreases appetite, while ghrelin increases it. Lack of sleep can lead to higher ghrelin levels and lower leptin levels, increasing hunger and potentially leading to weight gain.

Insulin: Sleep affects insulin sensitivity. Poor sleep can lead to insulin resistance, increasing the risk of type 2 diabetes.

Reproductive Hormones: Hormones like estrogen and testosterone are also influenced by sleep. Disrupted sleep can lead to imbalances, affecting reproductive health.

Getting adequate, quality sleep is essential for maintaining hormonal balance and overall health. If you have trouble sleeping, consider establishing a regular sleep schedule, creating a relaxing bedtime routine, and avoiding caffeine and electronics before bed.
