One of the things I notice in the Portland summers is that people get manic here when the days are longer and people are “enjoying the sun”. Sometimes I think it's a simple matter of sleep deprivation, which will make anyone crazed!
Melatonin, the sleep hormone, is produced in the pineal gland of the brain and is triggered by darkness. Not enough darkness causes a disruption in the bodies ability to produce melatonin, making sleep difficult.
Melatonin supplements are popular, but it's possible to help your body to create its own melatonin!: just add darkness! Having a dark bedroom is an excellent choice, stopping the use of electronic devices (screens, phones, etc) well before bedtime is sleep changing. Having an eye pillow can be one of the best tools for turning the body towards sleep, increasing melatonin and helping the body relax deeply. Sleeping better makes life better! Our eye pillows are silky soft and just heavy enough to keep the light out.
