Insomnia
When a person is not getting enough sleep, their body can’t replenish and repair itself. As a result, testosterone levels will naturally drop.
Insomnia affects one in three people over 65 years old, and it’s even more common among younger men with stressful jobs or children to take care of.
The best way to treat insomnia is by improving sleep habits, for example, keeping a regular bedtime schedule and avoiding caffeine at night. If a person still has trouble sleeping after trying these methods, they should talk to a doctor about taking a supplement that contains valerian or melatonin (natural substances found in plants).
