A bad night of sleep will do more than make you feel groggy the following day. In fact, it can do much worse than just that. Recent studies have shown that there is a direct link between lack of sleep and overeating, as well as lower levels of testosterone. Sound frightening? It should.
WHAT LINKS LACK OF SLEEP TO OVEREATING AND LOW TESTOSTERONE
SLEEP DEPRIVATION AND HUNGER
After a night of crappy sleep, your brain begins to crave fatty foods. This is no coincidence since the incomplete sleep cycle disrupts the regulation of appetite-related hormones called leptin and ghrelin.
Leptin is the hormone that regulates the feeling of satiety and ghrelin is our hunger hormone. When these two hormones are out of balance the result is an increase in appetite that causes us to eat on average more than 400 extra calories per day.
Studies showed that test subjects opted for food higher in saturated fat to satisfy their hunger. Apart from weight gain, this poses numerous heart-related health risks.
SLEEP DEPRIVATION AND TESTOSTERONE LEVELS
It has been shown in several studies that men who sleep less than five hours per night throughout the week experience a significant decrease in testosterone production. This is bad for several reasons.
Less testosterone means less anabolic activity in your body. This equates to higher cortisol levels resulting in more body fat and a decrease in lean muscle mass. Ever notice that after a period of poor sleep you look more bloated? That would be the cortisol spike in your body.
It’s obvious that sleep is a crucial part of our daily function in all areas of our physiology. If you have trouble sleeping at night, the first and best way to improve his situation is to turn off all devices an hour before you go to bed. Should this if you still experience problems sleeping, speak to a doctor about non-addictive remedies that you can take.
