Sun bathing or going for a walk in the sun can have many health benefits (with sunblock to protect your skin from ultraviolet rays), including battling depression. But what can bright lights do for our hormones? Well , researching scientists at the University of California ,San Diego , have discovered that great ammounts of LH (Luteinizing hormone) increased about 69% when male patients were exposed to bright lights very first in the morning for five days. Keep in mind that LH is the pituitary hormone that raises testosterone levels.Getting an hour of sunlight a day can be beneficial to releasing testosterone signals in the brain. Sunlight can also release endorphins which cause your seritonin levels to rise , which in effect can lift your mood. Getting sunlight also creates leptin in our body which has fat burning elements.Keeping a raised and healthy testosterone level may have many anti-depressant elements , help build muscle mass and keep a optimal libido. The next time you decide to watch TV the first thing in the morning , perhaps you could go for a short walk in the sunlight for a healthy alternative.
